Low Birth Weight is Associated with Sperm DNA Fragmentation and Assisted Reproductive Technology Outcomes in Primary Infertile Men: Results of a Cross-Sectional Study. World J Mens Health 2024; 42:384-393. [PMID: 37635336 PMCID: PMC10949032 DOI: 10.5534/wjmh.220283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 03/24/2023] [Accepted: 04/16/2023] [Indexed: 08/29/2023] Open
Abstract
PURPOSE To assess the relationship between clinical and semen characteristics and assisted reproductive technology (ART) outcomes with different birth weight (BW) categories in a cohort of infertile men. MATERIALS AND METHODS Data from 1,063 infertile men were analyzed. Patients with BW ≤2,500, 2,500-4,000, and ≥4,000 g were considered as having low BW (LBW), normal BW (NBW), and high BW (HBW), respectively. Testicular volume (TV) was assessed with a Prader orchidometer. Serum hormones were measured in all cases. Semen analyses were categorized based on 2021 World Health Organization reference criteria. Sperm DNA fragmentation (SDF) was tested in every patient and considered pathological for SDF >30%. ART outcomes were available for 282 (26.5%) patients. Descriptive statistics and logistic regression analyses detailed the association between semen parameters and clinical characteristics and the defined BW categories. RESULTS Of all, LBW, NBW, and HBW categories were found in 79 (7.5%), 807 (76.0%), and 177 (16.5%) men, respectively. LBW men had smaller TV, presented higher follicle-stimulating hormone (FSH) but lower total testosterone levels compared to other groups (all p<0.01). Sperm progressive motility (p=0.01) and normal morphology (p<0.01) were lower and SDF values were higher (all p<0.01) in LBW compared to other groups. ART pregnancy outcomes were lower in LBW compared to both NBW and HBW categories (26.1% vs. 34.5% vs. 34.5%, p=0.01). At multivariable logistic regression analysis, LBW was associated with SDF >30% (odd ratio [OR] 3.7; p<0.001), after accounting for age, Charlson Comorbidity Index (CCI), FSH, and TV. Similarly, LBW (OR 2.2; p<0.001), SDF >30% (OR 2.9; p<0.001) and partner's age (OR 1.3; p=0.001) were associated with negative ART outcomes, after accounting for the same predictors. CONCLUSIONS LBW was associated with impaired clinical and semen characteristics in infertile men compared to both NBW and HBW. SDF and ART outcomes were significantly worse in the LBW group.

Is It Time for Andrology and Endocrinology Professionals in Assisted Reproduction Centers? World J Mens Health 2023; 41:796-808. [PMID: 37118957 PMCID: PMC10523123 DOI: 10.5534/wjmh.220253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 12/23/2022] [Accepted: 01/18/2023] [Indexed: 04/03/2023] Open
Abstract
Epidemiologists indicate that about half of the couple's infertility cases are due to a male factor. Despite this, the role of andrologists or endocrinologists in assisted reproductive technique (ART) centers is still underestimated. According to our literature review, this reduces the chance of a thorough clinical evaluation of the male partners, which, sometimes consists only in a mere semen analysis, usually performed by laboratory technicians. A more complete diagnostic process could lead to the identification of potentially treatable causes of infertility, the recognition of diseases that require immediate treatment, and to the discovery of genetic diseases and, therefore, transmissible to the offspring. It can also increase the success rate of ART resulting in less psychological and financial burden for both public health resources and infertile couples. The presence of medical personnel with andrological and endocrinological skills in the ART centers represents the first step in creating 'precision medicine'. We hope that the guidelines of the various scientific societies will clearly contemplate this possibility.

Doppler ultrasound investigation of female infertility. Obstet Gynecol Sci 2023; 66:58-68. [PMID: 36647203 PMCID: PMC10025869 DOI: 10.5468/ogs.22131] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 11/05/2022] [Accepted: 01/02/2023] [Indexed: 01/18/2023] Open
Abstract
This study reviewed recent advances in the use of Doppler ultrasonography for the management and prediction of female infertility outcomes of assisted reproductive technology (ART). Color or power Doppler and three-dimensional power Doppler ultrasound can be used to measure vessels near the ovaries, uterus, and endometrium to assess blood flow. Increased blood flow and reduced resistance to the ovaries, uterus, and endometrium are associated with improved pregnancy outcomes, and their measurement has been suggested as a key factor in ART procedural outcomes. Perifollicular vascularity indices can help predict oocyte quality and maturity. Likewise, endometrial and uterine vascularity could be associated with endometrial receptivity and may assist with embryo transfer timing and pregnancy outcome predictions. With the advancement of Doppler ultrasound technology, this highly potent examination will be used more widely in routine clinical settings for the treatment of female infertility.

Long term all-cause and cardiovascular disease mortality among women who undergo fertility treatment. Med J Aust 2022; 217:532-537. [PMID: 36209740 PMCID: PMC9827840 DOI: 10.5694/mja2.51734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 08/30/2022] [Accepted: 09/05/2022] [Indexed: 11/07/2022]
Abstract
OBJECTIVES To compare age-adjusted all-cause and CVD mortality, relative to the general female population, for women registered for fertility treatment who received it and those who did not. DESIGN Prospective cohort study; analysis of Monash IVF clinical registries data, 1975-2018, linked with National Death Index mortality data. PARTICIPANTS All women who registered for fertility treatment at Monash IVF (Melbourne, Victoria), 1 January 1975 - 1 January 2014, followed until 31 December 2018. MAIN OUTCOME MEASURES Standardised mortality ratios (SMRs) for all-cause and CVD mortality, for women who did or did not undergo fertility treatment; SMRs stratified by area-level socio-economic disadvantage (SEIFA Index of Relative Socioeconomic Disadvantage [IRSD]) and (for women who underwent treatment), by stimulated cycle number and mean oocytes/cycle categories. RESULTS Of 44 149 women registered for fertility treatment, 33 520 underwent treatment (66.4%), 10 629 did not. After adjustment for age, both all-cause (SMR, 0.58; 95% CI, 0.54-0.62) and CVD mortality (SMR, 0.41; 95% CI, 0.32-0.53) were lower than for the general female population. All-cause mortality was similar for women registered with Monash IVF who did (SMR, 0.55; 95% CI, 0.50-0.60) or did not undergo fertility treatment (SMR, 0.63; 95% CI, 0.56-0.70). The SMR was lowest for both treated and untreated women in the fifth IRSD quintile (least disadvantage), but the difference was statistically significant only for untreated women. CVD mortality was lower for registered women who underwent fertility treatment (SMR, 0.29; 95% CI, 0.19-0.43) than for those who did not (SMR, 0.58; 95% CI, 0.42-0.81). CONCLUSION Fertility treatment does not increase long term all-cause or CVD mortality risk. Lower mortality among women registered for fertility treatment probably reflected their lower socio-economic disadvantage.

Evidence around early induction of labor in women of advanced maternal age and those using assisted reproductive technology. Best Pract Res Clin Obstet Gynaecol 2021; 77:42-52. [PMID: 34538560 DOI: 10.1016/j.bpobgyn.2021.08.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 07/20/2021] [Accepted: 08/10/2021] [Indexed: 11/21/2022]
Abstract
Worldwide, there has been a trend toward later motherhood. Concurrently, the incidence of subfertility has been on the rise, necessitating conception using assisted reproductive technologies (ARTs). These pregnancies are considered high risk due to fetal complications such as antepartum stillbirth and growth restriction and maternal complications such as increase in maternal morbidity and mortality. Early induction of labor can help to mitigate these risks. However, this has to be balanced against the iatrogenic harms of earlier delivery to both the baby, including respiratory distress and NICU stay, and the mother who might experience longer labor and other complications such as uterine hyperstimulation. Induction of labor at 39 weeks is the optimal timing for preventing antepartum stillbirth and avoiding iatrogenic harm. Delivery by elective cesarean section is not advocated as its benefits in these patients are unclear compared with the short- and long-term complications of a major abdominal surgery.

Abstract
Sperm DNA fragmentation (SDF) is implicated in male infertility and adverse reproductive outcomes. With the publication of many studies regarding the etiologies and contributors to SDF, as well as the effects of SDF, guidelines are necessary to aid clinicians in the application of SDF for male fertility evaluation. Two recent clinical practice guidelines were published by Agarwal et al and Esteves et al. In this article, we have evaluated and compared both guidelines. We have found fairly similar recommendations between the two guidelines and have also highlighted the differences between them. Finally, we have summarized and combined the best practice recommendations from both guidelines.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) employs the angiotensin-converting enzyme 2 (ACE2) receptor in the renin-angiotensin system for viral entry. The ACE2 receptor is present in both female and male reproductive systems, and reports of multi-organ involvement have led to uncertainty regarding its effects on the reproductive system and fertility. We review the existing literature regarding the function of ACE2 and the renin-angiotensin system in the female and male reproductive systems to postulate the possible implications of SARS-CoV-2 regarding fertility. Because of the presence of ACE2 in the ovaries, SARS-CoV-2 infection may disrupt ovarian function and hence oocyte quality. Higher expression of ACE2 in the endometrium with age and during the secretory phase raises concern about increased susceptibility to infection during periods of high ACE2 expression. The possibility of vertical transmission and the presence of ACE2 in the placenta and during pregnancy are also discussed. The presence of SARS-CoV-2 RNA in semen is controversial, but impaired semen quality has been found in men with moderate coronavirus disease 2019 infection. Evidence of orchitis and hormonal changes seen in male coronavirus disease 2019 infection may lead to infertility. The implications of these effects on assisted reproductive technology (ART) outcomes are also explored. The ART guidelines from different fertility societies for the management of patients treated with ART are provided. The importance of prioritising 'time-sensitive' patients for ART, counselling patients about the uncertainty and risks of ART, and pregnancy during the pandemic is discussed. Recommendations are also provided for infection control and safe regulation of ART centres and laboratories.

Abstract
Infertility is defined as the inability of a couple to succeed in achieving a spontaneous pregnancy after 1 year. Male and female factors contribute to infertility with approximately 40% each. In the remaining cases factors that affect fertility can be found in both partners. The andrological work-up should be started simultaneously with the gynecological diagnostic procedure in order to identify and treat andrological factors related to infertility. Since the majority of intracytoplasmic sperm injection procedures are performed due to andrological infertility, andrological diagnostics can prevent a delay in assisted reproductive technology. The andrological work-up can be necessary before 12 months of unsuccessful conception if the female partner is older than 35 years or andrological factors are present that could impair male fertility.

Abstract
The evaluation of female fertility at first diagnosis is an important premise and basis for determining the treatment scheme of assisted reproduction. In this study, a survey was conducted among 13 assisted reproductive institutions in China to understand the evaluation indicators and detection methods of female fertility at first diagnosis in various institutions, and provide a basis for reasonable selection of indicators. The survey showed that the indicators of female fertility evaluation at first diagnosis among assisted reproductive institutions included general health indicators, ovarian reserve indicators, and uterine conditions, etc. The selection of indicators was considerably consistent, but the detection methods were quite different. Therefore, it is necessary to choose the detection method with better validity and less harm.

Abstract
Background Human sperm cryopreservation is a simple and effective approach for male fertility preservation. Methods To identify potential proteomic changes in this process, data-independent acquisition (DIA), a technology with high quantitative accuracy and highly reproducible proteomics, was used to quantitatively characterize the proteomics of human sperm cryopreservation. Results A total of 174 significantly differential proteins were identified between fresh and cryoperservated sperm: 98 proteins decreased and 76 proteins increased in the cryopreservation group. Bioinformatic analysis revealed that metabolic pathways play an important role in cryopreservation, including: propanoate metabolism, glyoxylate and dicarboxylate metabolism, glycolysis/gluconeogenesis, and pyruvate metabolism. Four different proteins involved in glycolysis were identified by Western blotting: GPI, LDHB, ADH5, and PGAM1. Conclusions Our work will provide valuable information for future investigations and pathological studies involving sperm cryopreservation.

Abstract
PURPOSE Regulation of payment to gamete donors varies substantially across countries. The development of an ethically sustainable governance system of payments in gamete donation demands that the preferences of different stakeholders be heard. This study intends to contribute to improving the understanding of payment to gamete donors by analysing the views of donors and recipients about the preferred form of payment and its associations with their sociodemographic characteristics. METHODS This cross-sectional study included 70 donors and 172 recipients recruited at the Portuguese Public Bank of Gametes (July 2017-June 2018). Participants completed a self-reported questionnaire. Views about the preferred form of payment were collected through a multiple-choice question and an open-ended item. Associations were quantified through χ2 tests; content analysis was conducted with the open-ended answers. RESULTS Both donors (48.6%) and recipients (40.7%) considered that reimbursement is the preferred form of payment to ensure solidarity-based motivations to donate. This option was followed by compensation for non-financial losses (41.4% of donors; 33.7% of recipients) based on gender equity. Preference for a fixed reward (22.7% of recipients; 8.6% of donors) was less frequent among younger donors and married/living with a partner or employed recipients, being based on the promotion of equality. CONCLUSION In the context of the search for cross-border reproductive care and gamete circulation across countries, the findings from this study claim for the need to create solutions for payment to gamete donors that take into account gender equity and are simultaneously sensitive to donor's actual expenses and further health complications.

Abstract
During the last decades the study of male infertility and the introduction of the assisted reproductive techniques (ARTs) has allowed to understand that normal sperm parameters do not always predict fertilization. Sperm genetic components could play an important role in the early stages of embryonic development. Based on these acquisitions, several epigenetic investigations have been developed on spermatozoa, with the aim of understanding the multifactorial etiology of male infertility and of showing whether embryonic development may be influenced by sperm epigenetic abnormalities. This article reviews the possible epigenetic modifications of spermatozoa and their effects on male fertility, embryonic development and ART outcome. It focuses mainly on sperm DNA methylation, chromatin remodeling, histone modifications and RNAs.

Abstract
Objective: To evaluate the application value of the blastocysts derived from non-pronucleus (0PN) zygotes by the good quality blastocyst formation rate and the clinical outcomes of frozen-thawed blastocyst transfers. Methods: The good quality blastocyst formation rate derived from 0PN zygotes was compared with that derived from2 pronucleus (2PN) zygotes in in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles from January 2015 to December 2016. In addition, the clinical pregnancy, embryo implantation and live birth rates of frozen-thawed blastocyst transfers with blastocysts derived from 0PN and 2PN zygotes were analyzed on corresponding dates. Results: (1) In IVF cycles, the high quality blastocysts formation rate of 2PN embryos was significantly higher than that of 0PN (46.64% versus 42.42%, P<0.01) . In ICSI cycles, the high quality blastocysts formation rate of 2PN embryos was markedly higher than that of 0PN (41.96% versus 21.73%, P<0.01) . (2) In frozen-thawed embryo transfer cycles for IVF, the clinical pregnancy, implantation and live birth rates of D5 0PN blastocysts were significantly higher than those of D6 2PN (52.64% versus 46.78%, 49.91% versus 41.20%, 46.54% versus 39.56%, all P<0.05) , however, the abortion and newborn abnormal rates of D5 0PN blastocysts were lower than those of D6 2PN blastocysts (17.37% versus 23.36%, 1.31% versus 4.21%, both P<0.05) ; the clinical pregnancy, implantation and livebirth rates of D5 2PN blastocysts were significantly higher than those of D5 0PN (59.73% versus 52.64%, 55.95% versus 49.91%, 53.03% versus 46.54%, all P<0.05) , but newborn abnormal rate was a little higher than that of D5 0PN (3.90% versus 1.31%, P<0.05) ; the clinical pregnancy, implantation and live birth rates of D5 2PN blastocysts were significantly higher than those of D6 2PN (59.73% versus 46.78%, 55.95% versus 41.20%, 53.03% versus 39.56%, all P<0.05) , and the abortion rate of D5 2PN blastocysts was lower than that of D6 2PN blastocysts (18.23% versus 23.36%, P<0.05) . Conclusions: Although the blastocysts derived from 0PN could be transffered, the blastocysts derived from 2PN zygotes are preferred in all cycles. In IVF cycles, the good quality blastocysts derived from 2PN or 0PN zygotes will be transferred.

Abstract
Previous studies of associations between ASD and conception using assisted reproductive technology (ART) are inconsistent and few studies have examined associations with other infertility treatments or infertility disorders. We examined associations between ASD and maternal/paternal infertility disorders and numerous maternal treatments among 1538 mother-child pairs in the Study to Explore Early Development, a population-based case-control study. ASD was associated with any female infertility diagnosis and several specific diagnoses: blocked tubes, endometriosis, uterine-factor infertility, and polycystic ovarian syndrome. Stratified analyses suggested associations were limited to/much stronger among second or later births. The findings were not explained by sociodemographic factors such as maternal age or education or multiple or preterm birth. ASD was not associated with ART or non-ART infertility treatments.

Abstract
SUMMARY – We report a unique case of undetectable serum levels of anti-müllerian hormone (AMH) in women with polycystic ovary syndrome (PCOS) who developed ovarian hyperstimulation syndrome (OHSS) during in vitro fertilization (IVF). A case is described of a 28-year-old woman with clinical symptoms of PCOS and AMH serum level below analytical sensitivity (<1.0 pmol/L). After undergoing controlled ovarian stimulation, the patient developed OHSS. After follicle aspiration, seven oocytes were recovered. Three of them were used for intracytoplasmic sperm injection (ICSI) and fertilized, but with unsuccessful pregnancy outcome. A successful pregnancy was achieved in the second IVF/ICSI cycle with six oocytes retrieved and three embryos transferred. At 39 weeks of gestation, the patient delivered a healthy baby weighing 3930 g and 50 cm long. In conclusion, although AMH is considered a useful tool in ovarian reserve assessment and in predicting response to controlled ovarian hyperstimulation, the case presented shows that AMH should not be used as an independent ovarian marker.

Abstract
Objective: Explore the value of anti-Müllerian hormone (AMH) in predicting pregnant outcomes of polycystic ovary syndrome (PCOS) patients undergone assisted reproductive technology. Methods: The study totally recruited 1 697 patients who underwent the first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle in Sun Yat-sen Memorial Hospital from the January 2014 to December 2015. The patients were divided into two groups based on the age<35 (n=758) and ≥35 years old (n=939) , compare the basic data and pregnant outcomes of controlled ovarian hyerstimulation. Spearman correlation method was conducted to analyze the relations between AMH and clinical outcomes. The logistic regression method and partial correlation analysis were used to judge the main factors which determine pregnancy outcomes by controlled the confounding factors. The receiver operating characteristic curve (ROC) was used to evaluate the predictive sensitivity and specificity of AMH. Results: In the group of PCOS patient younger than 35 years, AMH were correlated with the number of antral follicles (r=0.388) and retrieved oocytes (r=0.235) . When the effect of total dosage and starting dosage of gonadotropin were controlled, AMH was still significantly associated with the number of retrieved oocytes (P<0.05) . AMH had no predictive value for the clinical pregnancy of PCOS patient younger than 35 years (area under ROC curve=0.481, P=0.768) . In the group of PCOS patient≥35 years old, AMH were correlated with the number of antral follicles (r=0.450) , retrieved oocytes (r=0.399) , available embryo (r=0.336) and high quality embryo (r=0.235) . When the effect of total dosage and starting dosage of gonadotropin were controlled, the correlations were still significant between those indexes (all P<0.05) . AMH had no predictive value for the clinical pregnancy of PCOS patient ≥35 years old (area under ROC curve=0.535, P=0.560) . However, the clinical pregnancy rate of the group of PCOS patient ≥35 years old was slightly higher than the control group (P=0.062) . Conclusions: AMH has no predictive value for the pregnancy outcome of PCOS patient. The pregnancy rate of PCOS patient ≥35 years old is slightly higher than the younger group, because the PCOS patient may have better ovarian reserve.

Abstract
Oxidative stress (OS) has been recognized as a significant cause of suboptimal assisted reproductive outcome. Many of the sperm preparation and manipulation procedures that are necessary in the in vitro environment can result in excessive production of reactive oxygen species (ROS) thereby exposing the gametes and growing embryos to significant oxidative damage. Antioxidants have long been utilized in the management of male subfertility as they can counterbalance the elevated levels of ROS inducing a high state of OS. Few studies have looked into the clinical effectiveness of antioxidants in patients undergoing assisted reproduction. While an overall favorable outcome has been perceived, the specific clinical indication and optimal antioxidant regimen remain unknown. The goal of our review is to explore the sources of ROS in the in vitro environment and provide a clinical scenario-based approach to identify the circumstances where antioxidant supplementation is most beneficial to enhance the outcome of assisted reproduction.
