Assessing obstetric outcomes: A systematic review and meta-analysis comparing fresh, artificial, and natural thaw embryo transfer cycles

BACKGROUND

The increasing utilisation of in vitro fertilisation (IVF) has prompted significant interest in determining the optimal endometrial environment to increase pregnancy rates and minimise the obstetric complications associated with various embryo transfer strategies.

AIMS

To determine which cycle is associated with increased obstetric complications: fresh embryo transfer (FreshET), natural thaw (NatThawET) or artificial thaw (ArtThawET). Outcomes of interest included: hypertensive disorders of pregnancy (HDP), gestational diabetes (GD), pre-term birth (PTB), post-partum haemorrhage (PPH) and large for gestational age (LGA).

MATERIALS AND METHODS

A comprehensive search of MEDLINE, EMBASE, CENTRAL, and PUBMED was conducted from 1947 to May 17, 2022. Two independent reviewers carried out the screening, and data extraction for the following comparisons: ArtThawET vs NatThawET, ArtThawET vs FreshET, and NatThawET vs FreshET. Meta-analysis was conducted using a fixed-effect Mantel-Haenszel model. The quality of the studies was assessed using GRADEpro.

RESULTS

A total of 23 studies were included in this review. ArtThawET was associated with a significantly increased odds of HDP (odds ratio (OR) 1.76, confidence interval (CI) 1.66-1.86), PTB (OR 1.18, CI 1.13-1.23), PPH (OR 2.61, CI 2.3-2.97) and LGA (OR 1.11, CI 1.07-1.15), compared to NatThawET. ArtThawET was also associated with increased odds of HDP (OR 2.13, CI 1.89-2.4), PPH (OR 3.52, CI 3.06-4.04) and LGA (OR 2.12, CI 1.77-2.56), compared to FreshET. Furthermore, NatThawET demonstrated increased odds of HDP (OR 1.20, CI 1.11-1.29), PPH (OR 1.25, CI 1.14-1.38) and LGA (OR 1.85, CI 1.66-2.07) compared to FreshET.

CONCLUSION

When clinically feasible, ArtThawET should be avoided as a first-line option for IVF to reduce the risk of obstetric complications. An adequately powered, multicentre randomised controlled trial is necessary to confirm these findings and investigate the underlying pathophysiology.

Assisted reproductive technology (ART) is not an independent risk factor for breech presentation among singleton term births in Vienna, Austria

Assisted reproductive technologies (ARTs) such as in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) are still discussed critically, as there is no consensus on whether these treatments could be the cause of risk factors for obstetric problems such as breech presentation. The aim of this study was to test the association between ART and breech presentation among 11920 singleton term births taking place in Vienna from 2010 to 2020. In this single-centre medical record-based study, data concerning the conception mode (spontaneous versus IVF or ICSI), child presentation, birth mode, newborn sex and size as well as age, height, weight, and reproductive history of the mother were included. Three hundred twenty-six newborns (2.7%) were conceived by IVF or ICSI, and 527 newborns (4.4%) were delivered in breech presentation. Breech presentation occurred in 7.6% of IVF/ICSI children but only in 4.3% of spontaneously conceived children (P = 0.019). ART increased the crude risk of breech presentation significantly (OR = 1.67; 95% CI 1.71 - 2.38). After adjusting for maternal age, height, number of previous births, smoking, and newborn sex, however, ART had no longer a significant impact on the risk of breech presentation. In contrast, breech presentation was significantly associated with higher maternal age as well as a lower number of previous births, but not with ART. This study shows that the adverse outcomes of IVF and ICSI pregnancies may not be due to the ART treatment alone but might also be due to the mostly higher age and lower parity of the mothers using ART.

Limited Effects of Ultra-low Oxygen Concentration during Extended Embryo Culture on In vitro Fertilisation Outcomes in Indian Women: A Retrospective Cross-sectional Study

Background

Amongst various other factors, oxygen (O2) concentration in embryo culture plays an important role in determining pregnancy outcomes in women undergoing in vitro fertilisation. Some studies have reported that lowering O2 levels in embryo culture provides better results.

Aims

To explore the effects of low- and ultra-low- O2 concentrations (5% and 2%, respectively) in extended embryo culture on various outcome parameters of pregnancy.

Settings and Design

This was a retrospective cross-sectional study.

Materials and Methods

In this study 382 participants had their embryos cultured in varying O2 concentrations (5% or 2%), followed by either a fresh embryo transfer (ET) or frozen embryo transfer (FET). Outcomes such as pregnancy rate, implantation rate, abortion rate, twinning rate, and live birth rate were compared between the groups.

Statistical Analysis Used

Chi square test was applied to compare the primary and secondary outcomes between different groups.

Results

No significant differences were observed in pregnancy rate and implantation rate between 5% and 2% O2 groups, irrespective of their mode of ET. The abortion rate was significantly higher in 5% O2 group than in 2% group during FET (24.71% vs. 11.49%, P = 0.02). While the proportion of good-quality embryos was higher in 5% O2 group, these did not translate to better pregnancy outcomes. Additionally, embryos cultured in 2% O2 concentration had a significantly better implantation rate when they were transferred fresh rather than frozen (71.34% vs. 61.46%, P = 0.04). There were no other differences observed.

Conclusion

Only marginal benefits were observed in switching human embryos to ultra-low O2 concentration after the initial days of culture.

Non-arteritic anterior ischemic optic neuropathy after uneventful delivery in a healthy woman

INTRODUCTION

Non-arteritic anterior ischemic optic neuropathy (NAION) is the most common cause of optic nerve swelling and optic neuropathy in adults over 50 years of age. It has been rarely reported during pregnancy, mostly related to systemic and ocular predisposing conditions.

CASE REPORT

We report the case of a 44 years-old healthy female with no previous remarkable clinical history. She had in vitro fertilisation treatment to get pregnant. 18 days after uneventful cesarean section she referred sudden painless vision loss in her right eye (RE), denser inferiorly, with concurrent optic disc edema and relative afferent pupillary defect. Steroid intravenous treatment during the acute episode showed no improvement. Our patient showed normal magnetic resonance imaging (MRI), blood test, autoimmune disease biomarkers, infectious serology and inflammatory markers. She was diagnosed of RE NAION. After one year follow-up visual field defect remains stable.

CONCLUSION

As far as we know this is the first report of NAION after in vitro fertilisation, uneventful pregnancy and cesarean section showing no systemic or ocular risk factors other than a small cup to disc ratio. Hemodynamic and hormonal changes during late pregnancy and uneventful cesarean section can trigger an episode of NAION in a healthy young woman.

Improving Fertility Treatment Documentation - A Survey

Background

Many couples do not have adequate documentation following fertility treatments.

Aims

To conduct a survey to understand the information needs of assisted reproductive technology physicians when assessing the reasons affecting treatment outcomes after intrauterine insemination (IUI) and in vitro fertilisation (IVF).

Settings and Design

Online survey.

Materials and Methods

Anonymous online survey of 14 parameters related to IUI treatment and 21 parameters related to IVF treatment, followed by recommendation of selected parameters for routine documentation.

Statistical Analysis Used

Frequency distribution calculation of responses.

Results

For IUI, total motile sperm count and post-wash sperm count and motility and for IVF, the quality and number of gametes, embryo number and morphology were the most important parameters.

Conclusion

The study creates recommendations for the minimum information desirable in the fertility treatment documentation given to the couple undergoing treatment.

Inequity of Access: Scoping the Barriers to Assisted Reproductive Technologies

Infertility impacts millions of people of reproductive age worldwide, with approximately 10-15% of couples affected. When infertility is present, there are many potential barriers to treatment, leading to inequity of access. Assisted reproductive technologies (ART) are the mainstay of medical treatment for infertility and include procedures such as in vitro fertilisation. This scoping review aims to explore the barriers to accessing assisted reproductive technologies to highlight a potential role for the pharmacist in addressing these barriers. Five databases, including CINAHL, Emcare, Medline, Scopus, and Web of Science, were searched using keywords that resulted in 19 studies that explored barriers to initially accessing or continuing ART. Studies identified more than one barrier to accessing ART, with the most mentioned barrier being the geographic location of the patient, with others themed as psychological, financial, minority groups, educational level, and the age of the patient. Recommendations were made to address barriers to accessing ART, which included changes to government regulations to increase health education and promotion of infertility. Pharmacists' accessibility, even in geographically remote locations, places them in an ideal position to address many of the challenges experienced by people accessing infertility treatment to improve outcomes for these people.

Adult granulosa cell tumour of the ovary incidentally discovered during caesarean section in a pregnant patient after IVF: a rare case and a review of the literature

Adult granulosa cell tumours (AGCTs) of the ovary are very rare during pregnancy. To date, only five cases of ovarian AGCT in pregnancy have been reported in the literature and the patients all conceived spontaneously. We report a case of AGCT of the ovary that was incidentally discovered during a caesarean section in a patient undergoing In vitro fertilisation (IVF). To the authors' knowledge, this is the first case of AGCT incidentally discovered during caesarean section in a pregnant patient after IVF. A 44-year-old primigravida with 39 weeks gestation was admitted to our hospital due to premature rupture of membranes in May 2019. She was treated by in vitro fertilisation due to being an elderly mother and she was pregnant after the first cycle. She was indicated for caesarean section due to conceiving following in vitro fertilisation and being an elderly mother. She gave birth to a 3,000 g baby boy and his Apgar scores were 8/1^'-9/5^'. When examining the adnexa, the left ovary had a tumour with a size of 7 × 4 × 4 cm. Left oophorectomy was performed and specimen sent to for histopathology. The histopathological diagnosis was an AGCT of the ovary. A month later, the patient received chemotherapy with Carboplatin and Paclitaxel for four cycles. After 32 months of follow-up, no recurrence was detected. In conclusion, AGCTs of the ovary are very rare during pregnancy. Pre-operative diagnosis is difficult. Conservative surgery should be considered in women who wish to have children. Patients should receive adequate counselling and long-term follow-up to ensure the highest survival rates and early detection of recurrence.

Is There a Relationship between Serum Anti-Mullerian Hormone Levels and Abortion Rates in Patients Who Received In vitro Fertilisation-Embryo Transfer Cycles?

Background

The studies which investigated the relationship between anti-Mullerian hormone (AMH) level and abortion rate have conflicting results.

Aims

This retrospective study aimed to evaluate the relationship between AMH levels and abortion in women who achieved pregnancy with in vitro fertilisation (IVF) treatment.

Settings and Design

This retrospective study was conducted in the Department of Gynecology and Obstetrics, Etlik Zubeyde Hanim Women's Health Training and Research Hospital, between January 2014 and January 2020.

Materials and Methods

Patients below 40 years of age who conceived after IVF-embryo transfer treatment during a 6-year period and had a serum AMH level measurement were included. The patients were divided into three groups according to the serum AMH levels as low AMH (L-AMH, ≤1.6 ng/mL), intermediate AMH (I-AMH, 1.61-5.6 ng/mL) and high AMH (H-AMH, >5.6 ng/mL). The groups were compared in terms of obstetric, treatment cycle characteristics and abortion rates.

Statistical Analysis Used

The Mann-Whitney U-test was used in comparison of non-parametric data of two groups; the Kruskal-Wallis test was used to compare the data of more than two groups. When a statistically significant difference was found in the Kruskal-Wallis test result, the groups were compared in pairs using the Mann-Whitney U-test, and the groups that made a statistical difference were determined. The Pearson's Chi-square and Fisher's exact tests were used to compare the independent categorical variables.

Results

L-AMH (n = 164), I-AMH (n = 153) and H-AMH (n = 59) groups were similar in terms of obstetric histories and number of cycles applied, with an abortion rate of 23.8%, 19.6% and 16.9%, respectively (P = 0.466). The same analyses were repeated in two subgroups under 34 years of age and above, and no difference was found in terms of miscarriage rates. The number of oocytes retrieved and the number of mature oocytes were higher in H-AMH group compared to intermediate and low groups.

Conclusion

No relationship was found between serum AMH level and abortion rate in women who achieved clinical pregnancy with IVF treatment.

The effect of hypnofertility on fertility preparedness, stress, and coping with stress in women having in vitro fertilization: A randomized controlled trial

BACKGROUND

In vitro fertilisation is a stressful process for women. Hypnofertility is a method that can be used to relieve stress during in vitro fertilisation. It is based on an effective and strong body-mind interaction, as well as balancing the brain and body via positive words and thoughts.

OBJECTIVE

This study aimed to investigate the effects of hypnofertility on fertility preparedness, stress, and coping with stress in women undergoing in vitro fertilisation.

METHODS

This study was conducted with a randomised controlled trial design. Hypnofertility-based relaxation, visualisation, imagination, and affirmation techniques were applied to the intervention group at four stages, and no initiative was applied to the women in the control group. The Clinical Trial Registration number of the study is NCT04755270.

RESULTS

After the hypnofertility method, the mean score of the intervention group in the positive feelings and thoughts subscale of the Fertility Preparedness Scale was higher than that of the control group (p < 0.05). The hypnofertility method caused a significant decrease in the level of infertility stress in the intervention group, and the intervention group used the active-confronting and passive-avoidance methods more than control group did (p < 0.05).

CONCLUSION

The hypnofertility method increased the levels of preparedness for fertility, reduced stress levels and provided effective strategies to cope with stress.

Surveys of clinician and patient attitudes to an add-on for in vitro fertilisation

BACKGROUND

Add-ons at the time of in vitro fertilisation (IVF) have become commonplace, despite a general lack of evidence that they are effective and safe. The 'Colorado Protocol' is a commonly used add-on consisting of aspirin, steroid and an antibiotic. Before commencing planning for a clinical trial evaluating the Colorado Protocol, researchers and funders need evidence that the Colorado Protocol is being prescribed, and to be assured that sufficient numbers of participants can be recruited for a clinical trial.

AIMS

To survey fertility clinicians and patients on attitudes toward use of add-ons during IVF, willingness of patients to be randomly assigned to an add-on trial treatment or placebo, and what would be the clinically meaningful outcomes, using the Colorado Protocol as a test case.

MATERIALS AND METHODS

Two online surveys were conducted: clinicians from fertility clinics across the United Kingdom, Australia, and New Zealand; and patients from Auckland-based clinics and NZ patient support groups.

RESULTS

Of 58 clinicians, 44 (75%) had recommended an add-on within the preceding year. Thirty-nine (67%) clinicians were aware of the Colorado Protocol, with 17 (29%) having recommended it within the preceding year. Of the 289 patients, 80% indicated willingness to take trial medications during IVF, and 68% were willing to be randomly assigned to the placebo arm of a trial. The median perceived minimum clinically important difference in live births in both samples was 5%.

CONCLUSIONS

A future trial of this add-on in IVF would be supported by patients in the context of the New Zealand fertility healthcare system.

Premature Progesterone Elevation in in vitro Fertilisation Cycles - Current Perspectives

The impact of premature elevation of progesterone (PPE) on the day of the trigger on pregnancy outcome in in vitro fertilisation (IVF) cycles has been a matter of contention and debate for decades. Research over the last 30 years has indicated that PPE >1.5 ng/ml is associated with declining live birth rates following fresh embryo transfer. Freeze-only approach has become a universal solution to overcome the issue of PPE. However, the topic is still mired with controversy. Few studies have not shown a negative impact on pregnancy rates. The impact of PPE on embryological parameters such as oocyte and embryo quality and ploidy is still very controversial. An important contentious issue is the choice of the threshold P value above which it is considered abnormal and a freeze-all strategy would be cost-effective. Currently, though a cutoff of >1.5 ng/ml is widely used, practices are not uniform and varying thresholds from 0.4 to 3 ng/ml are utilised. This review addresses the current understanding of PPE in IVF and the above controversies. The incidence, aetiology and source of progesterone rise, impact on endometrial receptivity, oocyte and embryo quality, impact on live birth and cumulative live birth and impact on frozen embryo transfer and donor oocyte cycles are discussed. Current controversies regarding the optimal threshold, assay performance and future directions are addressed.

Stimulation Duration in Patients with Early Oocyte Maturation Triggering Criteria Does Not Impact IVF-ICSI Outcomes

Results from studies reporting the optimal stimulation duration of IVF-ICSI cycles are inconsistent. The aim of this study was to determine whether, in the presence of early ovulation-triggering criteria, prolonged ovarian stimulation modified the chances of a live birth. This cross-sectional study included 312 women presenting triggering criteria beginning from D8 of ovarian stimulation. Among the 312 women included in the study, 135 were triggered for ovulation before D9 (D ≤ nine group) and 177 after D9 (D > nine group). The issues of fresh +/− frozen embryo transfers were taken into consideration. Cumulative clinical pregnancy and live-birth rates after fresh +/− frozen embryo transfers were similar in both groups (37% versus 46.9%, p = 0.10 and 19.3% versus 28.2%, p = 0.09, respectively). No patient characteristics were found to be predictive of a live birth depending on the day of ovulation trigger. Postponing of ovulation trigger did not impact pregnancy or live-birth rates in early responders. A patient’s clinical characteristics should not influence the decision process of ovulation trigger day in early responders. Further prospective studies should be conducted to support these findings.

Crossing the Hurdle of a Low Oocyte Yield in an in vitro Fertilization Cycle to Obtain Mature Oocytes

The complex process of oocyte maturation involves a coordinated set of events to take place so that an adequate number of oocytes can be obtained during an oocyte pickup procedure following controlled ovarian stimulation. A weak link in any of the steps can yield a sparse number of oocytes which can be a setback in the process.

The Use of Integrative Medical Services to Address Psychological Concerns around Infertility in an Indian Academic Medical Centre

Background

Alternative and complementary therapies have been gaining popularity as ways to reduce anxiety in patients.

Aim:

This study aimed to assess whether yoga and meditation could decrease the severity of anxiety in Indian women diagnosed with infertility Study.

Study Setting and Design:

This was a retrospective data analysis of anxiety score of 354 women undergoing treatment at a tertiary infertility hospital between January 2016 and December 2018.

Materials and Method:

Women participated in group yoga, meditation and counselling therapy intervention during their treatment period. A self-reported questionnaire that used the Generalised Anxiety Disorder-7 criteria measured the participants’ severity of anxiety at the start of and again at the end of the intervention.

Statistical Analysis:

Demographic analysis and a two-tailed paired t-test were applied between groups.

Results:

The results indicated that there was a statistically significant mean reduction (7.3 ± 2.7) in the anxiety scores of the participants between entry (12.94 ± 2.65) and following exposure (5.39 ± 1.99) to the intervention (P < 0.0001). The mean reduction in scores remained similar between participants who received ≤6 sessions (7.50 ± 2.68) and participants who received >6 sessions (7.10 ± 2.64) (P > 0.05). Among the participants that experienced mild anxiety at baseline (n = 43), 72.1% (n = 31) reported experiencing minimal anxiety following the intervention (P < 0.0001). Among those that experienced moderate anxiety at baseline (n = 213), 32.4% (n = 69) reported experiencing minimal anxiety post-intervention (P < 0.0001). Participants who expressed severe anxiety at baseline (n = 94, 26.6%), reported experiencing minimal anxiety (13.8% [n = 13)], mild anxiety (81.9% [n = 77]) and moderate anxiety (4.3% [n = 4]) after exposure to the intervention (P < 0.0001). None of the participants reported experiencing severe anxiety post-intervention.

Conclusion:

The benefits of alternative anxiety-reduction therapies for women diagnosed with infertility have been demonstrated in this study. These therapies can be used to complement the routine treatment of such patients.

Impact of COVID-19 Pandemic on Clinical and Embryological Outcomes of Assisted Reproductive Techniques

Background:

The emergence of the COVID pandemic unfolded a series of precautions and dilemmas and the complete suspension of health services. With the gradual emergence of data showing near minimal effects of the virus on pregnancy, Assisted Reproductive Techniques (ART) services were gradually resumed following guidelines and advisories.

Aim:

The purpose of this study was to detect the COVID positivity rate in women undergoing ART treatment during the COVID pandemic and compare clinical and embryological outcomes to the ART cycles performed in the pre-COVID era.

Study Setting and Design:

This was a retrospective cohort study of all women undergoing controlled ovarian stimulation, followed by a fresh or frozen embryo transfer (ET) between 1st October 2019 and 31st March 2020 (control group) and between 1st April 2020 and 31st September 2020 (study group) at Nova IVF Fertility Clinic, Ahmedabad.

Material and Methods:

The study group underwent ART during the first wave of COVID-19 pandemic in India and when gradual unlocking of facilities including ART was advised as per the national ART advisory by the ICMR in December 2020. The outcomes were compared with the control group (cycles in pre-covid time).

Statistical Analysis:

Statistical analysis was performed in SPSS (v25.0) and included Mann-Whitney U, Fisher's exact and Pearson Chi-square as appropriate. Values of P < 0.05 were considered statistically significant.

Results:

A total of 367 in vitro fertilisation (IVF) stimulations were initiated. A total of 342 retrievals and 606 ETs (171 fresh and 435 frozen) were completed during the study period with a COVID positivity rate of 6.8% (25/367) amongst fresh and 3.9% (18/453) amongst frozen ETs, respectively; the PR and IR in the study group was similar to the control group (47.6 vs. 55.1 P = 0.4 and 68.7 vs. 66.4; P = 0.52, respectively). The maternal complication rates were similar in both groups with a COVID positivity rate of 10.2% (23/225) and 1 maternal death in the study group. The live birth rates were similar.

Conclusions:

We did not find a noteworthy difference in the clinical and embryological outcomes in the IVF cycles conducted in the COVID era as compared to the pre-COVID time. Thus, with adequate precautions and safety measures, ART services conducted during the COVID pandemic have comparable birth outcomes and can be safely advocated.

Gastroenterology team members' knowledge and practices with fertility therapy for women with inflammatory bowel disease

INTRODUCTION

Fecundity may be reduced in women with active inflammatory bowel disease (IBD) or prior IBD-related surgery, and these women may require assisted reproductive technology (ART). There are no guidelines for women with IBD to outline referral criteria for ART.

METHODS

We performed a prospective, multicentre, international questionnaire of gastroenterologists, gastroenterology trainees, and IBD nurses. The primary outcome was to establish clinical practices and fertility therapy referral patterns among gastroenterology team members. We hypothesised that the lack of knowledge and awareness may delay or prevent initiation of fertility consultation referrals.

DISCUSSION

Of 182 participants, most had never initiated a referral for fertility therapy (69.8%), and of respondents who do initiate referrals, 50% wait until the patient has been unsuccessfully attempting conception for 12 months. Participants were significantly more likely to initiate a fertility therapy referral if they believed ART was effective (p = 0.038), not impeded by IBD-related surgery (p = 0.053), and if they had access to a dedicated IBD-pregnancy clinic (p = 0.027). Superior pregnancy knowledge was predictive of a greater likelihood of fertility therapy referrals (p = 0.037). All participants thought they had inadequate knowledge about ART in IBD, and 96.2% expressed desire to improve their knowledge.

CONCLUSION

Gastroenterology team members infrequently initiate referrals for fertility therapy consultation in women with IBD, increasing their risk of remaining childless. Implementation of dedicated IBD pregnancy clinics and targeted education programmes to increase awareness of ART in women with IBD might increase referral rates and reduce infertility.

Multifoetal gestations mediate the effect of in vitro fertilisation (IVF) on ischaemic placental disease in autologous oocyte IVF more than donor oocyte IVF

BACKGROUND

Ischaemic placental disease (IPD) affects 16%-23% of pregnancies in the United States. In vitro fertilisation (IVF) is a risk factor for IPD, and the magnitude of increase in risk differs for individuals using donor oocytes (donor IVF) versus their own oocytes (autologous IVF). In addition, multifoetal gestations, which are more common in IVF than non-IVF pregnancies, also are a risk factor for IPD.

OBJECTIVE

To quantify the contribution of multifoetal gestations to the association between IVF and IPD.

METHODS

We conducted a retrospective cohort study at a tertiary hospital from 1 January, 2000 to 1 August 2018 using electronic medical records and state vital statistics data. IPD was defined as preeclampsia, placental abruption, small for gestational age (SGA) birth or an intrauterine foetal demise due to placental insufficiency. We used mediation analysis to decompose the total effect of IVF on IPD into a natural direct effect and an indirect effect through multifoetal gestations. We repeated the analyses separately for donor and autologous IVF. All models were adjusted for maternal age, race, parity, insurance, year of delivery and account for multiple pregnancies per person.

RESULTS

We identified 86,514 deliveries, of which 281 resulted from donor IVF and 4173 resulted from autologous IVF. IVF pregnancies had 1.99 (95% CI 1.88, 2.10) times the risk of IPD compared to non-IVF pregnancies, and 75.5% of this increased risk was mediated by multifoetal gestations. Autologous IVF pregnancies had 1.95 (95% CI 1.84, 2.07) times the risk of IPD compared to non-IVF pregnancies, and the per cent mediated was 78.8%. Donor IVF pregnancies had 2.50 (95% CI 2.09, 2.92) times the risk of IPD, but the per cent mediated was 37.5%.

CONCLUSION

The majority of the association between autologous IVF and IPD was mediated through multifoetal gestations; however, this was not the case for donor IVF pregnancies.

Is Hysteroscopy Prior to IVF Associated with an Increased Probability of Live Births in Patients with Normal Transvaginal Scan Findings after Their First Failed IVF Trial?

(1) Background: Nowadays, pregnancy can be achieved by in vitro fertilisation (IVF) or by intracytoplasmic sperm injection (ICSI) for many infertile couples. However, implantation failure still remains a significant problem and it can be stressful for both patients and doctors. One of the key players for pregnancy achievement is the uterine environment. Hysteroscopy is the most reliable method to evaluate the uterine cavity and to identify any intauterine pathology. The aim of this retrospective study was to compare live birth ranges in between women who after a first failed IVF/ICSI attempt underwent a hysteroscopy and those who were evaluated by a transvaginal scan. (2) The retrospective study took place at the Assisted Reproductive Unit of the University Hospital of Ioannina, Greece, from 2017 to 2020. It included 334 women with normal findings in a repeat ultrasound scan after a failed IVF/ICSI trial, 137 of whom underwent in turn diagnostic hysteroscopy before the next IVF/ICSI. (3) Results: Live birth rates were higher in the study group (58/137 vs. 52/197 p = 0.0025). Abnormal endometrial findings were identified in 30% of the patients of the study group. (4) Conclusions: The addition of hysteroscopy as an additional investigation to those patients with a first failed IVF/ICSI could improve the rates of live births. A properly conducted RCT could lead to a robust answer.

'Just have some IVF!': A longitudinal ethnographic study of couples' experiences of seeking fertility treatment

We present findings from a longitudinal ethnographic study of infertile couples seeking treatment following initial GP referral to specialist fertility services. Repeated observations and interviews were undertaken with the same 14 heterosexual participants over an 18-month period. Heterosexual, non-donor couples comprise the majority of fertility clinic patients; however, research interest in this group has dwindled over time as IVF cycles have increased. In the United Kingdom, IVF is presented as a logical response to involuntary childlessness, and as an entirely predictable, and linear, course of action. The market is well-developed and often patients' first experience of privatised health care in the NHS. Our couples were challenged by this, and while they felt expected to move on to IVF, some wished to explore other options. While IVF is ubiquitous, the discomfort and challenge around fertility treatments remain; experiences are prolonged and characterised by recursive narratives and expressions of disequilibrium, which are rarely acknowledged and reflected in ongoing clinic-patient interactions. Our findings develop understanding of the process of 'mazing' (Image - The Journal of Nursing Scholarship, 1989, 21, 220), the pursuit of parenthood, by showing that the routine and normative status of IVF, at least in the current health care context, is at odds with the lived experiences of individuals.

Pregnancy outcome prediction after embryo transfer based on serum human chorionic gonadotrophin concentrations

OBJECTIVE

The aim of the study was to evaluate the predictive value of the human chorionic gonadotropin (hCG) concentration on the 14th and 16th post-ovulation day after embryo transfer/cryoembryo transfer as well as the dynamics of its increase with respect to the outcome of pregnancy.

MATERIALS AND METHODS

In total, 130 embryo transfers and cryoembryo transfers in women aged 22 to 38 years who experienced a single embryo transfer or single cryoembryo transfer with confirmed pregnancy (hCG level over 15 IU/l on 14th post-ovulation day - D14) were selected. The input parameters (hCG D14, hCG D16, hCG D16-D14, hCG D16/D14 and positivity of at least 2.5-fold increase in hCG D16 compared to hCG D14) were evaluated by regression analysis in relation to the outcome parameters (bio-chemical pregnancy, clinical pregnancy, clinical pregnancy terminated by abortion up to 12 weeks of gestation, clinical pregnancy terminated by childbirth).

RESULTS

Single concentrations of hCG D14 and D16, as well as the difference between these concentrations, were a statistically significant indicator of the prediction of bio-chemical pregnancy (P = 0.000215, P = 0.000227 and P = 0.000421). Contrary to expectations, the proportion of hCG D16 and D14 concentrations did not show statistical significance for either parameter, as well as the fulfilment of the condition of at least a 2.5fold increase in hCG D16 compared to D14. None of the studied input parameters was confirmed as a statistically significant marker for the prediction of miscarriage in the whole group of patients. However, in the group of confirmed clinical pregnancies, the serum concentration of hCG D16 (P = 0.0248) and the difference between concentrations D16 and D14 (P = 0.0185) were confirmed as a positive predictor of the progression of pregnancy until delivery.

CONCLUSIONS

Single hCG concentrations are a good prognostic factor for predicting the outcome of pregnancy, but the determination of the cut-off limit is limited by inter-laboratory deviation as well as by timing of blood collection for hCG determination on the exact post-ovulatory day. The results of individual studies are therefore difficult to use in clinical practice. The dynamics of hCG concentrations appear to be a more reliable predictor of pregnancy outcome. In our cohort, we confirmed the statistical significance of the difference in hCG concentration between the 16th and 14th post-ovulation day not only for the prediction of bio-chemical pregnancy, but also as a predictor of the progression of clinical pregnancy into childbirth. To determine the optimal values of this difference, it is necessary to evaluate a larger group of patients. Conversely, the statistical significance of the proportion of hCG concentrations between the 16th and 14th post-ovulation day was not  confirmed.

Use of kisspeptin to trigger oocyte maturation during in vitro fertilisation (IVF) treatment

Infertility is a major global health issue and is associated with significant psychological distress for afflicted couples. In vitro fertilisation (IVF) utilises supra-physiological doses of stimulatory hormones to induce the growth of multiple ovarian follicles to enable surgical retrieval of several oocytes for subsequent fertilisation and implantation into the maternal endometrium. The supra-physiological degree of ovarian stimulation can lead to potential risks during IVF treatment, including ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. The choice of oocyte maturation trigger, such as human chorionic gonadotrophin (hCG) or gonadotrophin releasing hormone agonist (GnRHa), can impact both the efficacy of IVF treatment with a bearing on luteal phase hormonal dynamics and thus the degree of luteal phase support required to maintain optimal pregnancy rates, as well as on safety of treatment with particular respect to the risk of OHSS. Kisspeptin regulates gonadotrophin releasing hormone (GnRH) release and is therefore a key regulator of the hypothalamo-pituitary-gonadal (HPG) axis. Kisspeptin has been shown to be requisite for the occurrence of the physiological ovulatory luteinising hormone (LH) surge. In this review, we discuss the potential use of kisspeptin as a novel trigger of oocyte maturation.

Effect of Acupuncture on Outcomes of In Vitro Fertilisation: A Scoping Review

OBJECTIVES

To identify, examine and summarize the available evidence on the effectiveness and safety of acupuncture for in vitro fertilisation (IVF) outcomes.

METHODS

Eight electronic databases, including PubMed, EMBASE, Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Database and VIP Database, were searched, supplemented by manual searches. Two researchers independently conducted the literature screening, data extraction, and methodological quality assessments. A narrative description was provided to show the general information and specific characteristics of the included studies. A bubble plot was used to visually display the overall effects of acupuncture on IVF outcomes.

RESULTS

Eighty-two studies were identified, including 64 primary studies and 18 systematic reviews. Transcutaneous electrical acupoint stimulation, electric acupuncture and manual acupuncture were applied in most studies and compared with no acupuncture, sham acupuncture and placebo acupuncture control groups. Sixty-three (98.4%) primary studies reported clinical pregnancy rate, and positive effects of acupuncture were found in 34 studies (54.0%). Live birth rate was reported in only 18 (28.1%) primary studies, of which 10 (55.6%) showed positive results. In addition, only 8 and 2 systematic reviews showed that acupuncture could increase clinical pregnancy events and live birth events, respectively. However, none of these reviews was of high methodological quality.

CONCLUSIONS

Available evidence suggests that acupuncture therapy could improve clinical pregnancy rates. However, whether acupuncture could increase live birth events was difficult to determine based on the few studies that have reported this outcome indicator. Furthermore, the methodological quality of most systematic reviews was assessed as critically low or low. Studies with a rigorous design and standardized implementation should be performed to refine the available evidence.

Effect of dehydroepiandrosterone administration before in vitro fertilization on the live birth rate in poor ovarian responders according to the Bologna criteria: A randomised controlled trial

OBJECTIVE

To evaluate the effect of dehydroepiandrosterone (DHEA) pre-treatment before in vitro fertilization and embryo transfer (IVF-ET) on the live birth rate in infertile women with poor ovarian response (POR) defined according to the Bologna criteria.

DESIGN

A randomized, double-blind, placebo-controlled trial.

SETTING

Nine reproductive medical centers in China.

POPULATION

A total of 821 participants with POR defined according to the Bologna criteria were enrolled in the study between April 2016 and December 2018.

METHODS

Eligible participants were randomly assigned to receive either DHEA (n = 410) or placebo (n = 411) treatments for 4-12 weeks prior to IVF-ET, in a 1:1 ratio.

MAIN OUTCOME MEASURES

Live birth rate after the first embryo transfer.

RESULTS

Thirty-six (8.8%) of 410 women in the DHEA group and 37 (9.0%) of 411 women in the placebo group had a live birth, with no significant difference observed between groups (relative risk, 0.98, 95% CI, 0.63-1.51; p = 0.911). There were no significant differences in the number of retrieved oocytes, and the rates of clinical pregnancy, pregnancy loss, and cumulative live births between the two groups.

CONCLUSIONS

DHEA administration prior to IVF-ET had no beneficial effect on the live birth rate relative to placebo in women with POR defined according to the Bologna criteria.

TWEETABLE ABSTRACT

No benefit was found in poor ovarian responders who received DHEA administration prior to IVF.

Use of platelet-rich plasma in the treatment of infertility in poor responders in assisted human reproduction procedures

Couple infertility is a pathology with an absolute number of cases growing markedly over the last decade in connection mainly with the increased age of couples wishing to conceive. Platelet-rich plasma (PRP) is an alternative treatment used for several years for experimental purposes. Yet, this method is not yet defined as a standard therapeutic option in the infertility protocol for poor responders in assisted human reproduction procedures. Thus, the present study is a retrospective study conducted between February 2019 and February 2020 to evaluate the effect of ovarian PRP injection in patients with a poor ovarian response (POR) to ovarian stimulation. Women (n=20; age 31-44 years) diagnosed with POR based on the European Society of Human Reproduction and Embryology criteria underwent ovarian injection with autologous PRP injection. Markers of ovarian reserve before, during the following two menstrual cycles, and at six months after treatment were followed as well as stimulation and fertilisation parameters before and post-treatment. PRP treatment resulted in increased antral follicle count and serum anti-Mullerian hormone, while levels of serum follicle-stimulating hormone and luteinising hormone were decreased. These changes were more pronounced during the 2nd menstrual cycle following treatment. By six months following the injection, their values return to pre-treatment levels and any small differences were not considered statistically significant. The average dose of gonadotropin used and duration remained statistically unchanged, but a significant increase in estradiol achieved by the day of the human chorionic gonadotropin trigger day was achieved. The cancellation rate decreased following PRP treatment while the number of collected oocytes, number of oocytes in metaphase II rose. The number of embryos (of A and B quality) resulting also increased but fell short of the significance level set (α=0.073). Following the PRP injection, two singleton pregnancies were achieved, resulting in live births at term without complications during pregnancy. Another pregnancy was achieved spontaneously 45 months following the PRP and a failed assisted human reproduction procedure. Although the group included a small number of women, the results indicate the potential benefits of an ovarian autologous PRP injection in women with POR. Positive results appear to be short-term for 2-6 months after the procedure.

Function of Follicular Cytokines: Roles Played during Maturation, Development and Implantation of Embryo

A balance within the immune system is necessary for the proper development of ovarian follicles. Numerous cytokines were detected in follicular fluid, the role of which in reproductive physiology seems crucial. They influence the development and maturation of the follicle, ovulation, and corpus luteum formation, as well as embryo implantation and maintenance of pregnancy. The analysis of follicular fluid requires its collection by puncturing of the ovary, which is usually executed in connection with various gynaecological procedures. When interpreting such test results, clinical indications for a given procedure and the method of patient preparation should be taken into account. This review revealed the results of currently available studies on the concentration of pro-inflammatory cytokines in follicular fluid in various forms of infertility. Additionally, it presented cytokines, whose concentration has a significant impact on the size of ovarian follicles, their number, the effectiveness of in vitro fertilisation, development of the embryo, and chances of correct implantation. Despite the many recent publications, the knowledge of follicular fluid immunology in the context of reproductive pathology is superficial and further research is required to extensively understand the roles of individual cytokines in reproductive pathology. In the future, this knowledge may enable patients’ individual qualifications to individual methods of infertility treatment, as well as the possible adjustment of the treatment regimen to the patient’s immune profile.

Severe Ovarian Hyperstimulation Syndrome in a Case of Nonmutated Recurrent Genuine Empty Follicle Syndrome

Empty follicle syndrome (EFS) is a rare event in which no oocytes are retrieved from apparently normal growing follicles with normal steroidogenesis despite meticulous follicular aspiration in assisted reproductive technology (ART) cycles. EFS is mainly of two types, genuine EFS and false EFS. Here, we report a case of a 24-year-old woman presenting with primary infertility with normal ovarian reserve and regular menstrual cycles, husband having severe “oligo-astheno-teratozoospermia,” and planned for ART treatment. We could not retrieve any oocytes in successive cycles despite optimum human chorionic gonadotropin (hCG) levels on the day of oocyte retrieval and using different management protocols mentioned until now in the literature. The whole genomic analysis was found to be normal (46, XX). Further, the patient had experienced severe ovarian hyperstimulation syndrome (OHSS) after the second cycle of ovarian stimulation despite no luteal hCG support. We were ineffectual to find the cause of recurrent EFS in this patient and therefore counseled the patient for donor oocytes. This case highlights the difficulty in treating genuine EFS patients and the need for monitoring serum estradiol levels during ovarian stimulation to prevent another serious complication of OHSS.

Enacting evidence-based medicine in fertility care: Tensions between commercialisation and knowledge standardisation

In this article we explore the recent enactment of evidence-based medicine (EBM) in the field of fertility care. We aim to contribute to the medical sociology literature through an analysis of how evidence is produced, interpreted and institutionalised in a relatively new medical field such as in vitro fertilisation (IVF), characterised by high uncertainty due to limited knowledge and high levels of commercialisation. Drawing on extensive ethnographic research conducted in England, this article explores the challenges IVF professionals encounter in producing credible data on the effectiveness of additional treatments, offering novel insights on the tensions between commercialisation and standardisation in the enactment of EBM. Extant medical sociology and Science and Technology Studies literature has shown the hidden professional work required to enact randomised control trials in practice. Our analysis shows that this hidden work is not enough when there is a broader lack of standardisation in both clinical and research practices, as producing 'good quality' evidence requires high levels of standardisation of knowledge production.

National Survey Highlights the Urgent Need for Standardisation of Embryo Transfer Techniques in the UK

Embryo transfer (ET) is one of the vital steps in the in vitro fertilisation (IVF) process, yet there is wide variation in ET technique throughout the UK, without a nationally approved standardised approach. The aim of this study was to gain contemporaneous information regarding the current clinical ET practice in the UK. Method: A 38-question electronic survey was distributed to the 79 UK Human Fertilisation and Embryology Authority (HFEA) registered clinics performing ETs. Results: In total, 59% (47/79) of units responded, 83% (39/47) performing ultrasound-guided transfers, with 42% (20/47) of units using a tenaculum; 22% (10/45) would proceed with transfer regardless of fluid in the endometrial cavity. In 91% (43/47) of units, embryos were deposited in the upper/middle portion of the uterine cavity, but interpretation of this area ranged from 0.5 to >2 cm from the fundus, with 68% (32/47) allowing patients to mobilise immediately after transfer. In 60% (27/45) of clinics, success rates were based on clinical pregnancy rates (CPR). Conclusion: Within the UK there is a wide range of variability in ET techniques, with >70% of discordance in survey-responses between clinics. Whilst there are areas of good practice, some disadvantageous techniques continue to persist. This survey emphasises the importance of developing a standardised, evidence-based approach to improve ET success rates.

In Vitro Fertilisation of Mouse Oocytes in L-Proline and L-Pipecolic Acid Improves Subsequent Development

Exposure of oocytes to specific amino acids during in vitro fertilisation (IVF) improves preimplantation embryo development. Embryos fertilised in medium with proline and its homologue pipecolic acid showed increased blastocyst formation and inner cell mass cell numbers compared to embryos fertilised in medium containing no amino acids, betaine, glycine, or histidine. The beneficial effect of proline was prevented by the addition of excess betaine, glycine, and histidine, indicating competitive inhibition of transport-mediated uptake. Expression of transporters of proline in oocytes was investigated by measuring the rate of uptake of radiolabelled proline in the presence of unlabelled amino acids. Three transporters were identified, one that was sodium-dependent, PROT (SLC6A7), and two others that were sodium-independent, PAT1 (SLC36A1) and PAT2 (SLC36A2). Immunofluorescent staining showed localisation of PROT in intracellular vesicles and limited expression in the plasma membrane, while PAT1 and PAT2 were both expressed in the plasma membrane. Proline and pipecolic acid reduced mitochondrial activity and reactive oxygen species in oocytes, and this may be responsible for their beneficial effect. Overall, our results indicate the importance of inclusion of specific amino acids in IVF medium and that consideration should be given to whether the addition of multiple amino acids prevents the action of beneficial amino acids.

Solved problems of reproductive medicine in the Czech Republic 2020

INTRODUCTION

During the 30th symposium of assisted reproduction held on November 11, 2020 in Brno, the solved problems in reproductive medicine in the Czech Republic in 2020 were presented. The selected topics have concerned not only current issues in the field of clinical embryology and genetics as well as gynecology, but also legislation and ethics. Discussed topics: 1. How much time does the doctor have in the CAR (centrum of assisted reproduction) outpatient clinic per patient and how does the embryologist communicate with clients? 2. Reproduction and PGT-M in oncology patients and patients at risk with hereditary oncogenic mutations. 3. Non-invasive genetic testing of embryos from culture medium. 4. Genome editing. 5. What is the need to monitor hormonal levels in stimulation protocols? 6. Monitoring and embryo selection for transfer/kryo. 7. Is it time to change the law on donor remuneration?

METHODS

The topics were prepared in advance by authorized members of our company with the task of elaborating theses, which they presented in a separate conference block. The presentation and the discussion were broadcast directly from the broadcast studio at Hotel International via an online connection. After the conference, all discussion topics and comments were incorporated.

CONCLUSION

The work presents the state of the solved problems of reproductive medicine in the Czech Republic.

Does acquired obstructive azoospermia have less impact than congenital azoospermia on ICSI results? Systematic review and meta-analysis

An electronic-based search was performed with MEDLINE bases through PubMed, Cochrane through Central, and Embase until August 2020 for the purpose of evaluating the impact of the aetiology of obstructive azoospermia on ICSI cycles. In the final analysis, there were 15 cohort studies included, comparing a group of patients with acquired azoospermia and others due to congenital bilateral absence of the vas deferens submitted to ICSI. Those 15 articles within 4,480 couples were analysed, and similar fertilisation rate (65.1% vs. 65.3%; p = .38), pregnancy rate per cycle (40.0% vs. 43.1%; p = .06) and live birth rate (29.6% vs. 30.0%;p = .76) were found between groups. Comparing specifically post-vasectomy azoospermia and congenital groups, both presented a similar fertilisation rate (62.4% vs. 53.4%, respectively; OR 1.10; 95% CI, 0.79, 1.54; p = .56; I²  = 89%) and pregnancy rate per cycle (39.4% vs. 35.6%, respectively; OR 1.26; 95% CI, 0.96, 1.66; p = .09; I²  = 0%). However, a higher live birth rate was identified in the congenital group compared to vasectomy group (28.4% × 19.5%; OR 1.54; 95% CI, 1.11, 2.15; p = .01; I²  = 0%). The reasons for that are unclear and factors such as couple age and sperm DNA fragmentation should be considered.

A report of pregnancy following ICSI in one of two sisters with familiar primary ciliary dyskinesia

Primary ciliary dyskinesia (PCD) is a disorder of structure and function of motor ciliary and dyskinetic activity of ciliary in the fallopian tubes of affected women and could lead to infertility in some cases. In vitro fertilisation (IVF) is a choice of treatment in infertile women with PCD, which could conquer the tubal dysfunction. In this case study, we report a PCD affected woman with infertility who was treated by IVF and pregnancy was achieved but it failed due to the spontaneous abortion. We also performed whole-exome sequencing for this case and her PCD-affected sister, which did not reveal any genetic abnormality related to the PCD or infertility.

Increased risk of severe maternal morbidity in women with twin pregnancies resulting from oocyte donation

STUDY QUESTION

Is there a difference in the risk of serious maternal complications during pregnancy and the postpartum in twin pregnancies according to mode of conception: natural conception, non-IVF fertility treatment, IVF, ICSI or oocyte donation?

SUMMARY ANSWER

Women with twin pregnancies after medically assisted reproduction (MAR) had an overall risk of serious maternal complications 30% higher compared with women with natural twin pregnancies, and this association varied according to the MAR procedure; the risk was increased by 50% with IVF using autologous oocytes and by 270% with oocyte donation.

WHAT IS KNOWN ALREADY

IVF has been reported as a risk factor for serious maternal complications in several concordant studies of singleton pregnancies. For twin pregnancies, this association is less well documented with imprecise categorisation of the mode of conception, and results are contradictory.

STUDY DESIGN, SIZE, DURATION

This is a secondary analysis of the national, observational, prospective, population-based cohort study of twin pregnancies (JUmeaux Mode d'Accouchement), which took place in France from 10 February 2014 through 1 March 2015. All French maternity units performing more than 1500 annual deliveries were invited to participate, regardless of their academic, public or private status or level of care. Of the 191 eligible units, 176 (92%) participated.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Women with a twin pregnancy who gave birth at or after 22 weeks of gestation were eligible (N = 8823 women included). We excluded women whose mode of conception was unknown (n = 75). Serious maternal complications were regrouped within the recently emerged concept of severe acute maternal morbidity (SAMM), as a binary composite outcome. The exposure of interest was the mode of conception, studied in five classes: natural conception (reference group), non-IVF fertility treatment including insemination and ovarian stimulation, IVF with autologous oocyte, ICSI with autologous oocyte and oocyte donation. To assess the association between the mode of conception and SAMM, we used multivariate logistic regression to adjust for confounders. Structural equation modelling (SEM) was used to explore the contribution to this association of potential intermediate factors, i.e. factors possibly caused by the mode of conception and responsible for SAMM: non-severe pre-eclampsia, placenta praevia and planned mode of delivery.

MAIN RESULTS AND THE ROLE OF CHANCE

Among the 8748 women of the study population, 5890 (67.3%) conceived naturally, 854 (9.8%) had non-IVF fertility treatment, 1307 (14.9%) had IVF with autologous oocytes, 368 (4.2%) had ICSI with autologous oocytes and 329 (3.8%) used oocyte donation. Overall, 538 (6.1%) developed SAMM. Women with twin pregnancy after any type of MAR had a higher risk of SAMM than those with a natural twin pregnancy, after adjustment for confounders (7.9% (227/2858) compared to 5.3% (311/5890), adjusted odds ratio (aOR) 1.3, 95% CI 1.1-1.6). This association varied according to the MAR procedure. The risk of SAMM was higher among women with IVF using either autologous oocytes (8.3%; 108/1307) or oocyte donation (14.0%; 46/329) compared with the reference group (respectively aOR 1.5, 95% CI 1.1-1.9 and aOR 2.7, 95% CI 1.8-4.1) and higher after oocyte donation compared with autologous oocytes (aOR 1.7, 95% CI 1.1-2.6). Conversely, the risk of SAMM for women with non-IVF fertility treatment (6.2%; 53/854) and with ICSI using autologous oocytes (5.4%; 20/368) did not differ from that of the reference group (5.3%; 311/5890) (respectively aOR 1.1, 95% CI 0.8-1.5 and aOR 0.9, 95% CI 0.6-1.5). The tested intermediate factors poorly explained these increased risks.

LIMITATIONS, REASONS FOR CAUTION

Beyond the confounders and intermediate factors considered in our analysis, specific causes of infertility and specific aspects of infertility treatments may explain the differences in the risk of SAMM by mode of conception. However, these data were not available.

WIDER IMPLICATIONS OF THE FINDINGS

Our study showed an increased risk of SAMM in women with twin pregnancies after MAR, notably after IVF using autologous oocytes and particularly after oocyte donation. To avoid unnecessary exposure to the high-risk combination of MAR and multiple pregnancies, transfer of a single embryo should be encouraged whenever possible. Knowledge of these differential risks may inform discussions between clinicians and women about the mode of conception and help to optimise obstetric care for women in subgroups at higher risk.

Cost effectiveness of in vitro fertilisation and preimplantation genetic testing to prevent transmission of BRCA1/2 mutations

STUDY QUESTION

Is it cost-effective to use in vitro fertilisation and preimplantation genetic testing of monogenic defects (IVT/PGT-M) to prevent transmission of BRCA1/2 mutations to second-generation new births in comparison with naturally conceived births?

SUMMARY ANSWER

In this cost-effectiveness analysis, we found that IVF/PGT-M is cost-effective for BRCA1 and BRCA2 mutation carriers if using a willingness to pay of $50 000 per quality-adjusted life-year (QALY).

WHAT IS KNOWN ALREADY

Carriers of a BRCA1 or BRCA2 mutation have a significantly increased risk of several types of cancer throughout their lifetime. The cost of risk reduction, screening and treatment of cancer in this population is high. In addition, there is a 50% chance of passing on this genetic mutation to each child. One option to avoid transmission of an inherited deleterious gene to one's offspring involves in vitro fertilisation with preimplantation genetic testing.

STUDY DESIGN, SIZE, DURATION

We implemented a state transition model comparing the healthcare impact of a cohort of healthy children born after IVF/PGT-M, who have a population risk of developing cancer, to a cohort of naturally conceived live-births, half of whom are carriers of the BRCA mutation. Transition probabilities are based on published sources, a lifetime horizon and a perspective of a provincial Ministry of Health in Canada.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The target population is the second-generation new births who have at least one parent with a known BRCA1 or BRCA2 mutation.

MAIN RESULTS AND THE ROLE OF CHANCE

At a willingness-to-pay threshold of $50 000 per QALY, IVF/PGT-M is a cost-effective intervention for carriers of either BRCA mutation. For BRCA1, the incremental cost-effectiveness ratio (ICER) for IVF/PGT-M is $14 242/QALY. For BRCA2, the ICER of intervention is $12 893/QALY. Probabilistic sensitivity analysis results show that IVF/PGT-M has a 98.4 and 97.3% chance of being cost-effective for BRCA1 and BRCA2 mutation carriers, respectively, at the $50 000/QALY threshold.

LIMITATIONS, REASONS FOR CAUTION

Our model did not include the short-term negative effect of IVF/PGT-M on the woman's quality of life; in addition, our model did not consider any ethical issues related to post-implantation genetic testing.

WIDER IMPLICATIONS OF THE FINDINGS

In countries in which the healthcare of a large segment of the population is covered by a single payer system such as the government, it would be cost-effective for that payer to cover the cost of IVF/PGT-M for couples in which one member has a BRCA mutation, in order to avoid the future costs and disutility of managing offspring with an inherited BRCA mutation.

Gynaecological and IVF procedures billed through the Medicare Benefits Schedule (MBS) during the COVID-19 pandemic

Background

In response to the COVID‐19 pandemic in Australia, restrictions to elective surgeries were implemented nationwide.

Aims

To investigate the response to these restrictions in elective gynaecological and In vitro fertilisation (IVF) procedures during the first wave of the COVID‐19 pandemic.

Materials and Methods

We analysed the Medicare Item Reports for the number of elective gynaecological (labioplasty, vulvoplasty; prolapse and continence; operative hysteroscopy; hysterectomy; fertility) and IVF procedures claimed in Australia between January–June 2020 and compared these to January–June 2019.

Results

The number of included gynaecological and IVF procedures performed in January–June 2020 decreased by −13.71% and −12.56%, respectively, compared to January–June 2019. The greatest reductions were in May 2020 (gynaecology −43.71%; IVF −51.63% compared to May 2019), while April 2020 reported decreases of −37.69% and −31.42% in gynaecological and IVF procedures, respectively. In April 2020, 1963 IVF cycle initiations (−45.20% compared to April 2019), 2453 oocyte retrievals (−26.99%) and 3136 embryo transfers (−22.95%) were billed. The procedures with greatest paired monthly decrease were prolapse and continence surgeries in April (676 procedures; −51.85%) and May 2020 (704 procedures; −60.05%), and oocyte retrievals in May 2020 (1637 procedures; −56.70%).

Conclusions

While we observed a decrease in procedural volumes, elective gynaecological and IVF procedures continued in considerable numbers during the restricted timeframes. In the event of future overwhelming biological threat, careful consideration must be given to more effective measures of limiting access for non‐emergency procedures to conserve essential resources and reduce risk to both the public and healthcare staff.

Breastfeeding following in vitro fertilisation in Switzerland-Does mode of conception affect breastfeeding behaviour?

Aim

Breastfeeding has numerous advantages. Our aim was to investigate whether breastfeeding initiation and duration in women with pregnancies conceived through in vitro fertilisation differ from spontaneously conceived pregnancies.

Methods

This is a comparative cross‐sectional study about breastfeeding behaviour performed at the Bern University Hospital including mothers of singletons conceived by in vitro fertilisation (n = 198) with or without gonadotropin stimulation between 2010 and 2016 (in vitro fertilisation group). They were compared to a population‐based control group (n = 1421) of a randomly selected sample of mothers in Switzerland who delivered in 2014.

Results

A total of 1619 women were included in this analysis. Breastfeeding initiation rates were high, similar between the in vitro fertilisation group (93.4%) and the control group (94.8%). No increased risk of stopping breastfeeding earlier after in vitro fertilisation treatment compared to the control group could be found over the observational period of 12 months (HR = 1.00, 95% CI 0.83‐1.20, P = .984). There was no difference in breastfeeding initiation or duration after gonadotropin‐stimulated vs unstimulated in vitro fertilisation.

Conclusion

In Switzerland, in vitro fertilisation treatments were not associated with earlier breastfeeding cessation. This result is reassuring for mothers undergoing in vitro fertilisation.

Human growth hormone use in poor ovarian response - caution and opportunities

Human growth hormone has found favour as a co-gonadotrophin in assisted reproduction particularly in the circumstances of a poor response to stimulation. Its use has been based on animal studies suggesting insulin-like growth factor-1 enhances granulosa and cumulus cell function and possibly oocyte quality. While there is limited ovarian cellular information in women, the use of human growth hormone is alleged to improve egg numbers, embryo quality, clinical pregnancies and live birth in women with a poor ovarian response. A number of cohort studies have claimed these benefits compared with prior nil treatment, but there are a limited number of quality randomised controlled studies. The few good randomised trials indicate an enhanced ovarian response in terms of oestradiol secretion and oocyte maturity with controversial improvement in ongoing pregnancy and live birth. Given the cost of the medication, the lack of convincing data on enhanced clinical outcomes and the theoretical possibility of side effects, we propose it is still too early to determine human growth hormone’s true cost-benefit for widespread use. However, a number of emerging randomised trials may tilt the equation to a positive outlook in the future. Meanwhile, the hormone should only be used after full informed consent from the patient as to its effectiveness and efficacy.

NGS-Based Application for Routine Non-Invasive Pre-Implantation Genetic Assessment in IVF

Although non-invasive pre-implantation genetic testing for aneuploidy (NIPGT-A) is potentially appropriate to assess chromosomal ploidy of the embryo, practical application of it in a routine IVF centre have not been started in the absence of a recommendation. Our objective in this study was to provide a comprehensive workflow for a clinically applicable strategy for NIPGT-A based on next-generation sequencing (NGS) technology with the corresponding bioinformatic pipeline. In a retrospective study, we performed NGS on spent blastocyst culture media of Day 3 embryos fertilised with intracytoplasmic sperm injection (ICSI) with quality score on morphology assessment using the blank culture media as background control. Chromosomal abnormalities were identified by an optimised bioinformatics pipeline applying copy number variation (CNV) detecting algorithm. In this study, we demonstrate a comprehensive workflow covering both wet- and dry-lab procedures supporting a clinically applicable strategy for NIPGT-A that can be carried out within 48 h, which is critical for the same-cycle blastocyst transfer. The described integrated approach of non-invasive evaluation of embryonic DNA content of the culture media can potentially supplement existing pre-implantation genetic screening methods.

Adenomyosis and Infertility-Review of Medical and Surgical Approaches

The aim of this review is to clarify the relative association between adenomyosis and infertility and the possible treatment for an infertile patient. Although adenomyosis is detected more often in women of late reproductive age, its influence on pregnancy rates is important, especially considering the tendency to delay pregnancy among women in developed countries. In this article, we present a critical analysis of the literature data concerning the impact of adenomyosis on fertility. The possible effects of treatment on the pregnancy rate will also be discussed. We conducted a literature search; publications from Pubmed, Embase and Cochrane databases published from 1982 to 2019 were retrieved using terms ’adenomyosis and infertility’ and ’adenomyosis and pregnancy outcomes’, extensively studied in the aspects of diagnosis, pathogenesis of infertility and possible treatment methods. Molecular studies have given deep insight into the pathogenesis of adenomyosis in the recent few years, but there is a huge discrepancy between in vitro studies and praxis. Oral contraceptive pills, anti-prostaglandins, oral or parenteral progestins, danazol and gonadotrophin-releasing hormone (GnRH) analogues have all been used to control menstrual pain and menorrhagia in women with adenomyosis, but they temporarily suppress the menstrual cycle. Additionally, endometrial ablation and hysterectomy used to alleviate pain caused by adenomyosis exclude pregnancy planning. The development of imaging techniques—ultrasound and MRI—enables the diagnosis of adenomyosis with very high accuracy nowadays, but the methods of treatment mentioned above have not given satisfactory results in women planning pregnancy. For these patients, the high-intensity-focused ultrasound method (HIFU) and combined treatment before assisted reproductive techniques can prove beneficial in adenomyosis patients.

Multiple myomectomy to aid fertility treatment - surgical and fertility outcomes: a retrospective cohort study

OBJECTIVE

To assess the effects of multiple myomectomy at laparotomy on fertility potential of infertile women who are planning to undergo assisted reproductive technology (ART) treatment.

METHODS

A retrospective single centre cohort study was conducted. Data of infertile women who were planning to undergo ART and underwent open myomectomy for multiple fibroids between January 2010 and December 2018 were reviewed. Data were collected on demographics, presenting symptoms, preoperative imaging findings, operative details, and postoperative and IVF outcomes. The primary outcome measure was the necessity for further hysteroscopic surgery prior to subsequent in vitro fertilisation (IVF) cycle. The secondary outcome measure was live birth rate.

RESULTS

A total of 55 women were included in the analyses. The median number of fibroids removed was 12 (range, 3-51). Thirteen (26%) women required further surgery before embryo transfer. In women with a breached endometrial cavity, the likelihood of further hysteroscopic division of intrauterine adhesions was increased 18-fold (P=0.017). Thirty-two women underwent 45 IVF cycles, 16 of which resulted in live birth (50%).

CONCLUSIONS

Infertile women with large and multiple fibroids could have good fertility outcomes following open myomectomy. Special care must be taken not to damage the uterine cavity. The intraoperative breach of the endometrial cavity seems to increase the risk of intrauterine adhesions, which may further compromise ART treatment and outcomes. Hysteroscopy prior to any embryo transfer cycle may help to optimise the endometrial cavity and fertility outcome in women who underwent multiple myomectomy.

Acupuncture versus placebo acupuncture for in vitro fertilisation: a systematic review and meta-analysis

OBJECTIVE

To evaluate the efficacy of acupuncture compared to placebo acupuncture for women undergoing in vitro fertilisation (IVF) in a systematic review and meta-analysis.

METHODS

A search was conducted in seven English-language biomedical databases from their inception to 3 April 2019 to identify studies evaluating acupuncture as an adjunct to IVF treatment. Randomised controlled trials (RCTs) that compared acupuncture with placebo acupuncture using a non-invasive placebo acupuncture device in women undergoing a fresh or frozen IVF cycle were eligible, as were studies that tested placebo acupuncture as the intervention. Outcomes were clinical pregnancy rate, ongoing pregnancy rate, miscarriage rate, live birth rate and adverse events.

RESULTS

Eight RCTs involving 3607 women were included. Studies were judged to be low risk for most of the risk of bias domains. Acupuncture around the time of embryo transfer was not significantly different to placebo acupuncture in terms of the clinical pregnancy rate (6 RCTs, 2473 women, risk ratio (RR) = 0.99 (95% confidence interval (CI) = 0.88, 1.11), I² = 51%, moderate certainty evidence), ongoing pregnancy rate (4 RCTs, 1459 women, RR = 0.88 (95% CI = 0.75, 1.02), I² = 50%, moderate certainty evidence), miscarriage rate (4 RCTs, 502 women, RR = 1.23 (95% CI = 0.89, 1.71), I² = 30%, high certainty evidence) or live birth rate (4 RCTs, 1835 women, RR = 0.87 (95% CI = 0.75, 1.01), I² = 0%, high certainty evidence). Outcomes with placebo acupuncture were not significantly different to usual care. Adverse events relating to acupuncture, such as discomfort and bruising, were mild to moderate.

CONCLUSION

Acupuncture administered around the time of embryo transfer did not have a statistically significant effect on IVF outcomes compared with placebo acupuncture.

Ameliorative effect of selenium nanoparticles on the structure and function of testis and in vitro embryo development in Aflatoxin B1-exposed male mice

The purpose of the research was to investigate the therapeutic ability of selenium nanoparticles (Se-NPs) on the aflatoxin B1 (AFB1) toxicity induced in the male reproductive system. For this experiment, the mature male mice were put into four groups. Control (0.5 ml PBS, 60 days; IP, n = 7), Se-NPs (0.5 µg kg^-1  day^-1 for 60 days; IP), AFB1 (4.5 mg kg^-1  day^-1 for 60 days; IP) and AFB1 + Se-NPs (4.5 mg kg^-1  day^-1  + 0.5 µg kg^-1  day^-1 for 60 days; IP). After treatment, the histological structure of testis, serum testosterone level and sperm parameters, including concentration, motility, viability, morphology and DNA fragmentation, were examined. The results demonstrated that the AFB1 destroyed the testicular tissue structure and decreased the sperm concentration, motility, viability and normal morphology significantly. AFB1 also could significantly increase sperm DNA fragmentation and reduce in vitro fertilisation and embryo development compared to the control group (p < .001). Our data show that Se-NPs could inhibit AFB1-induced damage to the testis and improve sperm parameters as well as in vitro fertilisation and embryo production in AFB1 exposed male mice. This study revealed that the administration of Se-NPs could attenuate the testicular injury of AFB1 and improve the male reproductive system function in AFB1 exposed mice.

Comparison of clinical efficacy of long- versus short-acting gonadotrophin-releasing hormone agonists for pituitary down regulation in In vitro fertilisation cycles

Background

Gonadotrophin-Releasing Hormone agonist (GnRHa) - long and short acting - is used for pituitary down regulation prior to ovarian stimulation in in vitro fertilisation (IVF) treatment. However, there are controversies in the literature as to their effectiveness, dose of gonadotrophin needed subsequently for ovarian stimulation and the clinical outcome.

Objective

The objective of the study was to compare the efficacy of single-dose long-acting GnRHa - goserelin - and daily dose short-acting GnRHa - buserelin - for pituitary down regulation and their clinical outcome in IVF treatment.

Materials and Methods

: This prospective comparative study was undertaken at the IVF centre in National Hospital Abuja, a public tertiary hospital in Nigeria. A total of 114 IVF patients were consecutively allocated into either long-acting GnRHa - goserelin - 3.6 mg single dose (Group A) or short-acting GnRHa - buserelin - 0.5 mg daily (Group B) both starting on day 21 of the cycle preceding the IVF treatment. The effects on pituitary down regulation and treatment outcomes were compared.

Results

Time taken (days) to achieve down regulation (22.6 ± 4.3 vs. 26.1 ± 8.0; P = 0.084) and the mean number of human menopausal gonadotrophin (HMG) doses used (57.7 ± 13.7 vs. 54.2 ± 16.7; P = 0.222) were similar in the two groups. Although the number of oocytes retrieved (9.9 ± 6.7 vs. 7.2 ± 5.0; P = 0.02) and fertilised (6.2 ± 4.4 vs. 4.6 ± 3.5; P = 0.04) were significantly higher in Group A, there was no statistically significant difference in the number of embryos (4.4 ± 2.6 vs. 4.0 ± 3.0; P = 0.850) and clinical pregnancy rate at 6 weeks (49.2% vs. 43.6%; odds ratio 1.249; confidence interval = 0.579-2.612; P = 0.578) in both the groups. While group B had a significantly higher number of hospital visits (P = 0.0001) as well as a higher number of injections (P = 0.0001), the mean cost of GnRHa and gonadotrophin used was significantly higher in Group A (P = 0.043).

Conclusion

Single-dose long-acting GnRHa is as effective as daily dose short-acting GnRHa for pituitary desensitisation prior to controlled ovarian stimulation in IVF cycles.

Predicting the chances of having a baby with or without treatment at different time points in couples with unexplained subfertility

STUDY QUESTION

Can we develop a prediction model that can estimate the chances of conception leading to live birth with and without treatment at different points in time in couples with unexplained subfertility?

SUMMARY ANSWER

Yes, a dynamic model was developed that predicted the probability of conceiving under expectant management and following active treatments (in vitro fertilisation (IVF), intrauterine insemination with ovarian stimulation (IUI + SO), clomiphene) at different points in time since diagnosis.

WHAT IS KNOWN ALREADY

Couples with no identified cause for their subfertility continue to have a realistic chance of conceiving naturally, which makes it difficult for clinicians to decide when to intervene. Previous fertility prediction models have attempted to address this by separately estimating either the chances of natural conception or the chances of conception following certain treatments. These models only make predictions at a single point in time and are therefore inadequate for informing continued decision-making at subsequent consultations.

STUDY DESIGN, SIZE, DURATION

A population-based study of 1316 couples with unexplained subfertility attending a regional clinic between 1998 and 2011.

PARTICIPANTS/MATERIALS, SETTING, METHODS

A dynamic prediction model was developed that estimates the chances of conception within 6 months from the point when a diagnosis of unexplained subfertility was made. These predictions were recomputed each month to provide a dynamic assessment of the individualised chances of conception while taking account of treatment status in each month. Conception must have led to live birth and treatments included clomiphene, IUI + SO, and IVF. Predictions for natural conception were externally validated using a prospective cohort from The Netherlands.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 554 (42%) couples started fertility treatment within 2 years of their first fertility consultation. The natural conception leading to live birth rate was 0.24 natural conceptions per couple per year. Active treatment had a higher chance of conception compared to those who remained under expectant management. This association ranged from weak with clomiphene to strong with IVF [clomiphene, hazard ratio (HR) = 1.42 (95% confidence interval, 1.05 to 1.91); IUI + SO, HR = 2.90 (2.06 to 4.08); IVF, HR = 5.09 (4.04 to 6.40)]. Female age and duration of subfertility were significant predictors, without clear interaction with the relative effect of treatment.

LIMITATIONS, REASONS FOR CAUTION

We were unable to adjust for other potentially important predictors, e.g. measures of ovarian reserve, which were not available in the linked Grampian dataset that may have made predictions more specific. This study was conducted using single centre data meaning that it may not be generalizable to other centres. However, the model performed as well as previous models in reproductive medicine when externally validated using the Dutch cohort.

WIDER IMPLICATIONS OF THE FINDINGS

For the first time, it is possible to estimate the chances of conception following expectant management and different fertility treatments over time in couples with unexplained subfertility. This information will help inform couples and their clinicians of their likely chances of success, which may help manage expectations, not only at diagnostic workup completion but also throughout their fertility journey.

In Vitro Fertilisation (IVF) Associated with Preimplantation Genetic Testing for Monogenic Diseases (PGT-M) in a Romanian Carrier Couple for Congenital Disorder of Glycosylation Type Ia (CDG-Ia): A Case Report

Background: Congenital disorder of glycosylation (CDG) is a severe morphogenic and metabolic disorder that affects all of the systems of organs and is caused by a mutation of the gene PMM2, having a mortality rate of 20% during the first months of life. Results: Here we report the outcome of an in vitro fertilisation (IVF) cycle associated with preimplantation genetic testing for monogenic diseases (PGT-M) in a Romanian carrier couple for CDG type Ia with distinct mutations of the PMM2 gene. The embryonic biopsy was performed on day five of the blastocyst stage for six embryos. The amplification of the whole genome had been realized by using the PicoPLEX WGA kit. Using the Array Comparative Genomic Hybridisation technique, we detected both euploid and aneuploid embryos. The identification of the PMM2 mutation on exon 5 and exon 6 was performed for the euploid embryos through Sanger Sequencing with specific primers on ABI 3500. Of the six embryos tested, only three were euploid. One had compound heterozygosity and the remaining two were simple heterozygotes. Conclusion: PGT-M should be strongly considered for optimising embryo selection in partners with single-gene mutations in order to prevent transmission to the offspring.

Preconception nutraceutical food supplementation can prevent oxidative and epigenetic DNA alterations induced by ovarian stimulation for IVF and increases pregnancy rates

BACKGROUND

It is hypothesized that oxidative and epigenetic alterations to DNA induced by ovarian stimulation for in vitro fertilization (IVF) may be associated with an increased risk of diseases and cancer in the offspring and could possibly be attenuated by preconception food supplementation.

METHODS

In a prospective randomised open-label trial, 62 patients were randomly assigned to either 30 days of preconception treatment with the nutraceutical Fertility woman ® duo (Nutriphyt, Beernem, Belgium) (group 1), this nutraceutical complemented with selenomethionine (group 2), or folic acid only (group 3). Biochemical and epigenetic effects and pregnancy rates were assessed.

RESULTS

In all 3 groups the level of DNA oxidative damage, estimated by the concentration of 8-hydroxy- 2-deoxyguanosine over creatinine in early morning urine, and the concentration of homocysteine in the blood decreased after treatment. In group 2, the degree of methylation of the cancer-associated CpG2 dinucleotide of the human Telomerase Reverse Transcriptase (hTERT) promoter region, assessed by pyrosequence in follicular cells obtained at oocyte pick-up, was 18% lower than that of group 3. The pregnancy rate, including the transfer of fresh and frozen embryos, was significantly higher in group 2 (50%) than in group 3 (6%) with the result in group 1 being intermediate (30%).

CONCLUSION

The results suggest that preconception food supplementation using a specific nutraceutical significantly reduces oxidative and epigenetic DNA changes to follicular cells of women treated by IVF, and may optimize gene expression in the oocytes, thus increasing the pregnancy rate per cycle of ovarian stimulation.

Form from Function, Order from Chaos in Male Germline Chromatin

Spermatogenesis requires radical restructuring of germline chromatin at multiple stages, involving co-ordinated waves of DNA methylation and demethylation, histone modification, replacement and removal occurring before, during and after meiosis. This Special Issue has drawn together papers addressing many aspects of chromatin organization and dynamics in the male germ line, in humans and in model organisms. Two major themes emerge from these studies: the first is the functional significance of nuclear organisation in the developing germline; the second is the interplay between sperm chromatin structure and susceptibility to DNA damage and mutation. The consequences of these aspects for fertility, both in humans and other animals, is a major health and social welfare issue and this is reflected in these nine exciting manuscripts.

Acute cardiovascular changes in women undergoing in vitro fertilisation (IVF), a systematic review and meta-analysis

OBJECTIVES

Ovarian stimulation during fertility treatment leads to profound maternal physiological changes. Women undergoing in vitro fertilisation (IVF) may be at an increased risk of future cardiovascular morbidity, though little is known about the effects on maternal cardiovascular function. We aim to systematically review whether IVF treatment is associated with changes in maternal haemodynamic parameters, and the effects of different protocols.

STUDY DESIGN

A systematic review and meta-analysis of English language studies identified on Medline and EMBASE database, between 1978, to 2019. Search terms: IVF, maternal haemodynamics, and cardiovascular. Studies reporting on ovulation induction, intrauterine insemination, and oocyte donation were excluded. Methodological quality was assessed by using the adapted Critical Appraisal Skills Programme (CASP) checklist. A meta-analysis was conducted for blood pressure and heart rate on patients undergoing the long GnRH agonist protocol according to Cochrane guidelines. We considered four time points in the IVF cycle, in chronological order: pre-treatment, pituitary down regulation, peak oestradiol and the luteal phase.

RESULTS

Nine suitable studies were identified; four fulfilled the criteria for meta-analysis. Two studies measuring heart rate found a significant increase in heart rate from pituitary down-regulation to peak estradiol levels, which was supported by the meta-analysis (3.78 ± 2.18 (p= < 0.0001)). Three studies reported a significant decrease in blood pressure from baseline, with those suitable for meta-analysis showing a significant decrease in mean arterial pressure (-2.08 ± 1.79 (p= < 0.0001)). Cardiac functional changes were reported for all studies and the changes depended on the type of protocol used.

CONCLUSIONS

In Vitro Fertilisation leads to acute changes in maternal haemodynamics at different time points of the stimulation protocol. We found an increase in heart rate from pituitary down-regulation to peak estradiol levels and a significant decrease in blood pressure from baseline or pituitary down-regulation to the luteal phase. Cardiac functional changes were reported for all studies on the agonist protocol, but no significant changes were found using the antagonist protocol. It remains unclear as to whether these acute changes were associated with pregnancy complications or chronic cardiovascular sequelae.

Patient identified factors influencing decisions to seek fertility care: adaptation of a wellness model

Objective: To adapt a fertility care wellness model.Background: Despite availability of a range of diagnostic and therapeutic services for infertility, many do not seek care or discontinue care prior to achieving a live birth. Wellness models can inform research on patient decisions to seek and continue fertility care, as many barriers and drivers are represented within the dimensions of wellness.Methods: A mixed-methods online survey was completed by 135 people of reproductive age who experienced infertility in the USA. Outcomes included drivers and barriers to seeking or continuing fertility care. Identified factors were compared by treatment history using chi-square and Fisher's exact tests. Themes and patterns were identified within 174 responses to 6 open-response items through conventional content analysis.Results: Thematic analysis revealed practical (environmental, financial, and physical) and affective (emotional, social and spiritual) dimensions of wellness in decisions to seek care (67%), with affective rationales more prominent in decisions to return for care (78%).Conclusion: Decisions to seek fertility care and return after failed treatment integrate practical and affective rationales from financial, physical, environmental, emotional, social and spiritual wellness dimensions. Drivers and barriers within these dimensions should be considered to encourage care seeking and improve patient retention.
