Sekhon L, Shaia K, Santistevan A, Cohn KH, Lee JA, Beim PY, Copperman AB. The cumulative dose of gonadotropins used for controlled ovarian stimulation does not influence the odds of embryonic aneuploidy in patients with normal ovarian response. J Assist Reprod Genet 2017; 34:749-758. [PMID: 28321529 DOI: 10.1007/s10815-017-0909-3] [Citation(s) in RCA: 47] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2016] [Accepted: 03/08/2017] [Indexed: 11/29/2022] Open
Abstract
OBJECTIVE Controlled ovarian hyperstimulation (COH) promotes multifollicular growth, increasing the chance of obtaining euploid embryos that will successfully implant. Whether aneuploidy is increased from COH with exogenous gonadotropins interfering with natural selection of dominant follicles is a concern. This study evaluates the association between gonadotropin exposure and aneuploidy. METHODS This is a retrospective cohort study of 828 patients that underwent 1122 IVF cycles involving controlled ovarian stimulation and trophectoderm biopsy for preimplantation genetic screening (PGS), from 2010 to 2015. Polymerase chain reaction (PCR) was used to assess aneuploidy. Kruskal-Wallis tests and logistic regression with generalized estimating equations (GEEs) were used for data analysis. RESULTS Overall, after controlling for patient age, ovarian reserve, stimulation protocol, days of stimulation, and diagnoses, there was no significant association between cumulative gonadotropin (GND) dose and the odds of aneuploidy (adjusted OR = 1.049, p = 0.232). Similarly, in cycles where patients did not require COH beyond cycle day 12, there was no significant association between cumulative gonadotropin dose and the odds of aneuploidy (adjusted OR = 0.909, p = 0.148). However, in cases where patients were stimulated past cycle day 12, there was a significant increase in the odds of aneuploidy (adjusted OR = 1.20, 95% CI 1.125-1.282, p < 0.0001) with increasing cumulative gonadotropin dose, with a small effect size (Cohen's d = 0.10, 95% CI 0.08-0.12). In this cohort, there was a 16.4% increase in the odds of aneuploidy for each 1000-u increase in cumulative GND exposure (adjusted OR = 1.164, p = 0.002). When the analysis was restricted to low responders (peak estradiol <500 pg/mL or <4 mature follicles achieved; there was no significant association between gonadotropin dose and aneuploidy (adjusted OR = 1.12, 95% CI 0.982-1.28, p = 0.09), regardless of the duration of COH required to reach vaginal oocyte retrieval. CONCLUSION The degree of exposure to exogenous gonadotropins did not significantly modify the likelihood of aneuploidy in patients with a normal ovarian response to stimulation (not requiring COH beyond cycle day 12). Patients requiring prolonged COH were demonstrated to have elevated odds of aneuploidy with increasing cumulative gonadotropin dose. This finding may reflect an increased tendency towards oocyte and embryonic aneuploidy in patients with a diminished response to gonadotropin stimulation.

Abstract
INTRODUCTION With increasing survival rates after treatment for cancer in prepubertal girls and women of reproductive age, an increasing focus on quality of life has emerged. Both irradiation and cytotoxic drugs can be detrimental to future fertility, consequently several treatment alternatives have been developed to spare or restore fertility in young females diagnosed with cancer. One of these options is cryopreservation of ovarian tissue before treatment and autotransplantation at a later time. MATERIAL AND METHODS We present the Norwegian experience after 11 years of practice with ovarian tissue cryopreservation. A total of 164 patients have had ovarian tissue cryopreserved during the period 2004-2014. Fifteen patients died during the observation period. Six patients requested autotransplantation, which was performed in two women. RESULTS Both patients conceived, one spontaneously and one after assisted reproduction due to a concomitant male factor. The pregnancies were uneventful and they each gave birth to a healthy child. CONCLUSIONS Cryopreservation with later autotransplantation of ovarian tissue should be offered to a selected group of young women with cancer.

Abstract
The following review aims to examine the available evidence to guide best practice in preventing ovarian hyperstimulation syndrome (OHSS). As it stands, there is no single method to completely prevent OHSS. There seems to be a benefit, however, in categorizing women based on their risk of OHSS and individualizing treatments to curtail their chances of developing the syndrome. At present, both Anti-Müllerian Hormone and the antral follicle count seem to be promising in this regard. Both available and upcoming therapies are also reviewed to give a broad perspective to clinicians with regard to management options. At present, we recommend the use of a "step-up" regimen for ovulation induction, adjunct metformin utilization, utilizing a GnRH agonist as an ovulation trigger, and cabergoline usage. A summary of recommendations is also made available for ease of clinical application. In addition, areas for potential research are also identified where relevant.

Presence of bile acids in human follicular fluid and their relation with embryo development in modified natural cycle IVF. Hum Reprod 2015; 30:1102-9. [PMID: 25753582 DOI: 10.1093/humrep/dev034] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2014] [Accepted: 02/03/2015] [Indexed: 12/20/2022] Open
Abstract
STUDY QUESTION Are bile acids (BA) and their respective subspecies present in human follicular fluid (FF) and do they relate to embryo quality in modified natural cycle IVF (MNC-IVF)? SUMMARY ANSWER BA concentrations are 2-fold higher in follicular fluid than in serum and ursodeoxycholic acid (UDCA) derivatives were associated with development of top quality embryos on Day 3 after fertilization. WHAT IS KNOWN ALREADY Granulosa cells are capable of synthesizing BA, but a potential correlation with oocyte and embryo quality as well as information on the presence and role of BA subspecies in follicular fluid have yet to be investigated. STUDY DESIGN, SIZE, DURATION Between January 2001 and June 2004, follicular fluid and serum samples were collected from 303 patients treated in a single academic centre that was involved in a multicentre cohort study on the effectiveness of MNC-IVF. PARTICIPANTS/MATERIALS, SETTING, METHODS Material from patients who underwent a first cycle of MNC-IVF was used. Serum was not stored from all patients, and the available material comprised 156 follicular fluid and 116 matching serum samples. Total BA and BA subspecies were measured in follicular fluid and in matching serum by enzymatic fluorimetric assay and liquid chromatography-mass spectrometry, respectively. The association of BA in follicular fluid with oocyte and embryo quality parameters, such as fertilization rate and cell number, presence of multinucleated blastomeres and percentage of fragmentation on Day 3, was analysed. MAIN RESULTS AND THE ROLE OF CHANCE Embryos with eight cells on Day 3 after oocyte retrieval were more likely to originate from follicles with a higher level of UDCA derivatives than those with fewer than eight cells (P < 0.05). Furthermore, follicular fluid levels of chenodeoxycholic derivatives were higher and deoxycholic derivatives were lower in the group of embryos with fragmentation compared with those without (each P < 0.05). Levels of total BA were 2-fold higher in follicular fluid compared with serum (P < 0.001), but had no predictive value for oocyte and embryo quality. LIMITATIONS, REASONS FOR CAUTION Only samples originating from first cycle MNC-IVF were used, which resulted in 14 samples only from women with an ongoing pregnancy, therefore further prospective studies are required to confirm the association of UDCA with IVF pregnancy outcomes. The inter-cycle variability of BA levels in follicular fluid within individuals has yet to be investigated. We checked for macroscopic signs of contamination of follicular fluid by blood but the possibility that small traces of blood were present within the follicular fluid remains. Finally, although BA are considered stable when stored at -20°C, there was a time lag of 10 years between the collection and analysis of follicular fluid and serum samples. WIDER IMPLICATIONS OF THE FINDINGS The favourable relation between UDCA derivatives in follicular fluid and good embryo development and quality deserves further prospective research, with live birth rates as the end-point. STUDY FUNDING/COMPETING INTERESTS This work was supported by a grant from the Netherlands Organisation for Scientific Research (VIDI Grant 917-56-358 to U.J.F.T.). No competing interests are reported.

Abstract
In contrast to current approaches, the aim of mild stimulation is to develop safer and more patient-friendly protocols in which the risks of the treatment as a whole are minimized. Mild stimulation is defined as the method when exogenous gonadotropins are administered at lower doses, and/or for a shorter duration in GnRH antagonist co-treated cycles, or when oral compounds (antiestrogens, aromatase inhibitors) are used for ovarian stimulation for IVF, with the aim of limiting the number of oocytes obtained to fewer than eight. In this chapter we discuss the relevant physiology of follicle development, the development of milder stimulation protocols, the implications of mild stimulation, the current state of affairs, and future developments.

Abstract
PURPOSE Natural cycle (NC) IVF/ICSI has proven to be an alternative to conventional IVF/ICSI cycles. METHODS Within our retrospective, observational study (n = 159) infertile couples underwent (n = 463) cycles of NC-IVF/ICSI from May 2007 until December 2011. Oocyte pick-up was performed within a pure natural cycle excluding any hormonal stimulation except of hCG for ovulation induction. Oocytes were fertilized by IVF/ICSI and embryo transfer took place 2 or 3 days later. In addition, the current literature was analysed concerning pregnancy rates in NC-IVF/ICSI cycles. RESULTS Oocyte pick-up was performed in n = 463 NC and was successful in n = 342 cases (IVF n = 135, ICSI n = 207). 203 oocytes were fertilized (IVF n = 87, ICSI n = 116, FR 59.4 %) and lead to 192 embryo transfers. Finally, 25 pregnancies were reached (PR 13.0 % per transfer) resulting in four biochemical pregnancies, 7 (33.3 %) miscarriages, one pregnancy of unknown outcome and 13 live births. Within the current literature (n = 27 studies), PR in NC-IVF/ICSI cycles varied between 10.2 and 50 %. CONCLUSIONS Within our study, pregnancy rates in pure NC-IVF/ICSI remained below 15 %. Although this may be linked to unfavourable preconditions like patients' age >40 years, low ovarian reserve or long duration of infertility, further improvement is necessary to increase pregnancy rates.

Abstract
Modified natural-cycle IVF has a lower pregnancy rate per started cycle as compared with IVF with ovarian stimulation due to, for example, premature ovulation. Indometacin administered before ovulation prevents follicle rupture. Therefore, addition of indometacin may improve the effectiveness of modified natural-cycle IVF. This double-blind, randomized, placebo-controlled trial with indometacin or placebo in 120 women aged 27-36 years compared the number of patients without premature ovulation as compared with the number of patients with one or more ovulations in a maximum of six cycles. Indometacin had no significant influence on the probability of a premature ovulation in patients during the six cycles (OR 2.38, 95% CI 0.94-6.04). A subgroup analysis showed a significant influence of indometacin in decreasing the probability of a premature ovulation in cycles without LH surge at the day of human chorionic gonadotrophin administration (OR 8.29, 95% CI 1.63-42.3, P=0.009). Although this study could not detect a significantly lower ovulation rate in the indometacin group versus the placebo group, the data suggest that a subgroup of patients without LH surge prior to oocyte retrieval might benefit from indometacin in modified natural-cycle IVF.

Abstract
The efficacy of assisted reproductive technologies has improved significantly over the past decades. The main indications for in vitro fertilisation include tubal obstruction, severe male-factor infertility, severe endometriosis, ovulatory dysfunction, diminished ovarian reserve, and infertility of unexplained cause. In vitro fertilisation has also become an effective treatment option for couples wishing to undergo pre-implantation genetic diagnosis or screening, and for those wishing to cryopreserve their oocytes or embryos for preservation of fertility. The management of women in late reproductive age poses a major challenge; the optimum in vitro fertilisation treatment for poor responders remains elusive. The success of in vitro fertilisation treatment can be optimised by taking an individualised, patient-centered approach to controlled ovarian hyperstimulation. Key components involve selection of an appropriate controlled ovarian protocol, close-cycle monitoring, adjustment of gonadotropin dosage to avoid hyper-response, and individualised timing of human chorionic gonadotropin injection. Future directions of assisted reproductive technologies include development of non-invasive embryo selection methods, use of transcriptomics, proteomics, metabolomics, and time-lapse imaging technologies.

Abstract
A retrospective cohort study was conducted in a private infertility centre to evaluate the use of non-steroidal antiinflammatory drugs (NSAID) in natural-cycle IVF (nIVF) treatment. A total of 1865 first-rank nIVF cycles performed during 2009–2010 were evaluated. Low-dose, post-trigger NSAID was administered in a non-randomized way in cycles at higher ovulation risk where an imminent LH surge was detected on triggering day. Main outcome measures were premature ovulation rate, embryo transfer rate per scheduled cycle and clinical pregnancy and live birth rates per embryo transfer. NSAID use was associated with a significantly lower risk of premature ovulation (3.6% versus 6.8%, adjusted OR 0.24, 95% CI 0.15–0.39, P < 0.0001) and higher embryo transfer rate (46.8% versus 39.5%, adjusted OR 1.38, 95% CI 1.06–1.61, P = 0.012) per scheduled cycle. Clinical pregnancy (39.1% versus 35.9%) and live birth rates per embryo transfer (31.3% versus 31.4%) were comparable. In this retrospective series, short-term low-dose NSAID application positively influenced nIVF cycles by diminishing the rate of unwanted premature ovulations and increasing the proportion of cycles reaching embryo transfer.

Abstract
Objective To compare the IVF outcomes of mild ovarian stimulation with conventional ovarian stimulation in poor responders. Methods From 2004 to 2009, 389 IVF cycles in 285 women showed poor responses (defined as either a basal FSH level ≥12 mIU/mL, or the number of retrieved oocytes ≤3, or serum E2 level on hCG day <500 pg/mL) were analyzed, retrospectively. In total, 119 cycles with mild ovarian stimulation (m-IVF) and 270 cycles with conventional ovarian stimulation (c-IVF) were included. Both groups were divided based on their age, into groups over and under 37 years old. Results The m-IVF group was lower than the c-IVF group in the duration of stimulation, total doses of gonadotropins used, serum E2 level on hCG day, the number of retrieved oocytes, and the number of mature oocytes. However, there was no significant difference in the number of good embryos, the number of transferred embryos, the cancellation rate, or the clinical pregnancy rate. In the m-IVF group over 37 years old, the clinical pregnancy rate and live birth rate were higher when compared with the c-IVF group, but this result was not statistically significant. Conclusion In poor responder groups, mild ovarian stimulation is more cost effective and patient friendly than conventional IVF. Therefore, we suggest that mild ovarian stimulation could be considered for poor responders over 37 years old.

Abstract
OBJECTIVE To describe pregnancies and live births resulted from natural cycle IVF combined with in-vitro maturation (natural-cycle IVF/IVM) for three poor responder women after failure of stimulated cycles. METHODS For case 1 and 2, the mature oocytes from aspirated follicles were inseminated by intracytoplasmic sperm injection (ICSI) immediately; immature oocytes were matured in vitro, and the embryos from mature and immature oocytes transferred on day 3 after oocyte retrieval. For case 3, 3 consecutive natural cycles were performed, in which the matured oocytes from in vivo or in vitro were vitrified in the first and second cycle, and warmed on the retrieval day of the third fresh cycle. Then the embryos resulted from vitrified-warmed and fresh oocytes were transferred. RESULTS A total of 15 oocytes were obtained from the 7 retrieval cycles for the three cases. The case 1 was successfully pregnant at her first natural cycle, and case 2 was pregnant after two consecutive cycles. The two cases had successfully delivered and case 3 was in her ongoing pregnancy at the time of submission. CONCLUSION These results demonstrate that natural-cycle IVF/IVM might be a reasonable and efficient treatment alternative for poor responder patients when stimulated cycle has failed.

Abstract
Controlled ovarian hyperstimulation (COH) using a gonadotrophin-releasing hormone (GnRH) analogue plus gonadotrophins is used widely in in vitro fertilization (IVF), but there can be significant complications. Sixty women with a normal ovarian response participated in a comparison of COH (triptorelin [GnRH agonist] 0.1 mg/day SC from day 21 of the menstrual cycle [before the IVF cycle] and recombinant follicle-stimulating hormone (FSH) 150 - 300 IU/day from day 2 of the IVF cycle, when triptorelin was reduced to 0.05 mg/day) with a modified natural cycle (MNC) treatment (human menopausal gonado trophin [HMG] 150 IU/day IM if serum oestradiol was ≤ 50 pg/ml on day 2 or 3 of the menstrual cycle). The groups did not differ significantly in implantation rate (21.1% and 22.6%, respectively) and clinical pregnancy rate (30.0% and 30.0%, respectively). When comparing successful pregnancies, MNC patients had significantly lower values than COH patients for total amount of gonadotrophin (HMG and recombinant FSH) used, number of oocytes retrieved and medication cost. It is concluded that MNC seems to be a feasible treatment option, with low medication cost, relatively low risk of complications and, possibly, greater patient acceptability.

Is the birthweight of singletons born after IVF reduced by ovarian stimulation or by IVF laboratory procedures? Reprod Biomed Online 2010; 21:245-51.

Abstract
Singletons born after IVF are at risk of adverse pregnancy outcome, the cause of which is unknown. The present study investigated the influence of ovarian stimulation and IVF laboratory procedure on birthweight. Birthweight of singleton pregnancies resulting from IVF treatment with (n=161) and without ovarian stimulation (using a modified natural cycle (MNC) protocol; n=158), and spontaneous conceptions in subfertile patients (n=132) were compared. Mean+/-SD birthweight of singletons after conventional IVF with ovarian stimulation, MNC-IVF and natural conception were 3271+/-655, 3472+/-548 and 3527+/-582 g (P=0.001). After adjustment for biological and social confounders, the difference in birthweight between conventional IVF and MNC-IVF was reduced to 88 g and the differences between conventional IVF and MNC-IVF versus spontaneous conceptions to 123 and 23 g, respectively. The results lead to three conclusions. First, a major part of the crude differences in birthweight between the three groups is related to patient and pregnancy characteristics. Second, the IVF laboratory procedure has no influence on birthweight. Third, although a trend towards lower birthweight after ovarian stimulation was found, an adverse effect of ovarian stimulation on birthweight was not substantiated.

Abstract
Background Multiple pregnancies are high risk pregnancies with higher chances of maternal and neonatal mortality and morbidity. In the past decades the number of multiple pregnancies has increased. This trend is partly due to the fact that women start family planning at an increased age, but also due to the increased use of ART. Couples with unexplained or mild male subfertility generally receive intrauterine insemination IUI with controlled hormonal stimulation (IUI COH). The cumulative pregnancy rate is 40%, with a 10% multiple pregnancy rate. This study aims to reveal whether alternative treatments such as IVF elective Single Embryo Transfer (IVF e SET) or Modified Natural Cycle IVF (MNC IVF) can reduce the number of multiple pregnancy rates, but uphold similar pregnancy rates as IUI COH in couples with mild male or unexplained subfertility. Secondly, the aim is to perform a cost effective analyses and assess treatment preference of these couples. Methods/Design We plan a multicentre randomised controlled clinical trial in the Netherlands comparing six cycles of intra-uterine insemination with controlled ovarian hyperstimulation or six cycles of Modified Natural Cycle (MNC) IVF or three cycles with IVF-elective Single Embryo Transfer (eSET) plus cryo-cycles within a time frame of 12 months. Couples with unexplained subfertility or mild male subfertility and a poor prognosis for treatment independent pregnancy will be included. Women with anovulatory cycles, severe endometriosis, double sided tubal pathology or serious endocrine illness will be excluded. Our primary outcome is the birth of a healthy singleton. Secondary outcomes are multiple pregnancy, treatment costs, and patient experiences in each treatment arm. The analysis will be performed according tot the intention to treat principle. We will test for non-inferiority of the three arms with respect to live birth. As we accept a 12.5% loss in pregnancy rate in one of the two IVF arms to prevent multiple pregnancies, we need 200 couples per arm (600 couples in total). Discussion Determining the safest and most cost-effective treatment will ensure optimal chances of pregnancy for subfertile couples with substantially diminished perinatal and maternal complications. Should patients find the most cost-effective treatment acceptable or even preferable, this could imply the need for a world wide shift in the primary treatment.

Abstract
BACKGROUND Gonadotropin-releasing hormone (GnRH) analogues are used routinely to prevent a premature luteinizing hormone (LH) surge in women undergoing assisted reproductive technology (ART) treatments. In contrast to GnRH agonists, antagonists produce rapid and reversible suppression of LH with no initial flare effect. OBJECTIVE To review the role of cetrorelix, the first GnRH antagonist approved for the prevention of premature LH surges during controlled ovarian stimulation in modern ART. METHOD A review of published literature on cetrorelix. RESULTS Both multiple- and single-dose cetrorelix protocols were shown to be at least as effective as long GnRH agonist regimens for pituitary suppression in Phase II/III clinical trials. Furthermore, cetrorelix co-treatment resulted in similar live birth rates but a shorter duration of gonadotropin stimulation, a lower total gonadotropin dose requirement and lower incidence of ovarian hyperstimulation syndrome compared with long agonist regimens. A single-dose cetrorelix protocol further decreased the number of injections required. Preliminary studies have also produced promising data on the use of cetrorelix in modified ART protocols, such as frozen embryo transfer and donor oocyte recipient cycles. CONCLUSION Cetrorelix offers a potential therapeutic alternative to GnRH agonists during controlled ovarian stimulation and has become an integral part of modern, patient-friendly reproductive medicine.

Abstract
This study compared serum and follicular anti-müllerian hormone, LH, FSH, E(2), and P concentrations in modified natural cycles and controlled ovarian hyperstimulation cycles to analyze their effect on oocyte and embryo quality and implantation. Follicular anti-müllerian hormone, FSH, E(2), and P concentrations had no effect on embryo quality, whereas high serum and follicular LH concentrations in natural cycles modified only with hCG did not compromise oocyte and embryo quality but might have a negative effect on implantation.

Abstract
OBJECTIVE To study in the French Context women's experiences with a low-stimulation regimen of in vitro fertilisation (Friendly IVF) and to compare them with those of women undergoing standard IVF (S-IVF). POPULATION AND METHODS Two assisted reproduction technology centers participated in this preliminary study. Patients'views were explored qualitatively. In-depth interviews were conducted at the end of the second monitored cycle. Twelve friendly IVF patients and 13 S-IVF patients participated in the study. RESULTS The respondents indicated that the most positive aspect of Friendly IVF was the low doses of hormones used. Cancellation of cycles and failure of oocyte retrieval were perceived the most negatively. Women in the Friendly IVF group reported fewer side effects and expressed emotional distress less acutely than women in the S-IVF group. The Friendly IVF treatment was percieved as a first step, sustaining the hope of success with a standard treatment. CONCLUSION Friendly IVF, as practiced in the center studied, represents a valuable alternative for most respondents as a first step in IVF treatment.

Abstract
OBJECTIVE To study the implantation potential of unselected embryos derived from modified natural cycle IVF according to their morphological characteristics. DESIGN Cohort study. SETTING Academic department of reproductive medicine. PATIENT(S) A series of 449 single embryo transfers derived from modified natural cycle IVF. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Ongoing implantation rate according to embryo characteristics. RESULT(S) The best implantation was found in embryos with 4 and 8 cells on day 2 and 3 respectively, <or=10% fragmentation, and absence of multinucleated blastomeres. In contrast to findings from other studies, we found embryos with fewer than four blastomeres on day 2 to do relatively well. Furthermore, we found the implantation potential of embryos containing multinucleated blastomeres to be less severely impaired than expected. CONCLUSION(S) Findings from this study suggest that in currently used embryo scoring systems, the implantation potential of embryos with low numbers of blastomeres on day 2, as well as embryos containing multinucleated blastomeres, is underestimated. However, it is unclear whether the results of our study apply to embryos derived from controlled ovarian hyperstimulation cycles.

Abstract
OBJECTIVE To determine the role of the natural cycle for in vitro fertilization (IVF) in poor responder patients. DESIGN Retrospective survey. SETTING Private center for assisted reproduction. PATIENT(S) 294 women who were poor responders in a previous IVF cycle. INTERVENTION(S) Analysis of 500 consecutive natural cycles IVF. MAIN OUTCOME MEASURE(S) Number of cycles with oocytes, pregnancy rate per cycle, per transfer, and implantation rate. RESULT(S) Oocytes were found in 391 cases (78.1%), and cleaving embryos suitable for transfer were obtained in 285 cycles (57.0%). Pregnancy was observed in 49 cases, with a pregnancy rate of 9.8% per cycle, 17.1% per transfer, and 16.7% per patient. The patients were subdivided arbitrarily by the women's age into three groups. Patients 35 years old or younger showed a pregnancy rate of 18.1% per cycle, 29.2% per transfer, and 31.7% per patient. Women aged between 36 and 39 years showed a pregnancy rate of 11.7% per cycle, 20.6% per transfer, and 20.3% per patient. Women 40 years old or older showed a pregnancy rate of 5.8% per cycle, 10.5% per transfer, and 9.7% per patient. No differences were found for any of the evaluated parameters, independent of which cycle was the first, the second, third, fourth, or fifth, or further consecutive cycle. CONCLUSION(S) In poor responder patients, natural-cycle IVF is an effective treatment, especially in younger women.

Abstract
PURPOSE While performing the mild ovarian stimulation protocol with a GnRH antagonist, the pregnancy rate was compared between the groups, which were divided by the degree that the luteinizing hormone (LH) level decreased. MATERIALS AND METHODS Patients aged 27 to 42years (36.1 +/- 3.79) underwent 308 IVF cycles who opted for IVF via the mild ovarian stimulation protocol began clomiphene citrate on day 3 and recombinant FSH on day 5. A GnRH antagonist was administered when the dominant follicle reached 14mm. Serum LH was measured at the time of GnRH antagonist administration and at the time of hCG injection. The pregnancy rate and implantation rate were compared between 50 cycles in which the LH level dropped less than one-third and the control (LH level within 1/3). RESULT(S) The pregnancy rate for the group in which the LH level fell less than one third was 18%. Conversely, the pregnancy rate for the control group was 39%. The implantation rate was 18% for the less than one-third group and 26% for the control group. Both the pregnancy rate and the implantation rate for the group in which the LH level fell less than one-third were significantly lower than that of control (p < 0.02). CONCLUSION(S) When performing the mild ovarian stimulation protocol, serum LH should be followed. If the serum LH level is less than one-third at the time of hCG injection, both the pregnancy rate and implantation rate are significantly lower.

Abstract
OBJECTIVE Low dose stimulation (LS) is emerging as an alternative regime in assisted reproductive technology (ART). This study aimed to compare the cost-effectiveness of LS to the high dose GnRH antagonist (Atg) regime. METHODS An observational prospective study conducted at an academic infertility unit from January to June 2007. Outcome measures included the numbers of follicles, oocytes and embryos, morphological quality of oocytes and embryos, clinical pregnancy (PR) and complication rate. RESULT Ninety five first attempt ICSI cycles consisting of 54 LS and 41 Atg were analyzed. Subjects in both groups had comparable sociodemographics and reproductive characteristics. LS generated significantly fewer follicles, total oocytes, mature oocytes (all p < 0.0005) and immature oocytes (p = 0.009) than Atg but the number of excellent quality oocytes was similar. Significantly fewer embryos were available in LS although the proportion of usable embryos was higher, 83.2% vs. 67.0% for Atg. Mean embryos per transfer was 2.0 +/- 1.1 vs. 2.6 +/- 1.0 (p = 0.02) for a clinical PR per transfer of 43.2% vs. 50.0% for LS and Atg respectively. LS regime had a shorter gonadotrophin administration period with resultant COH cost one third of the Atg protocol (both, p < 0.0005). The cost per live birth per started cycle worked out to be USD 13,200 and 24,900 for LS and Atg respectively. Furthermore, LS had fewer incidences of OHSS compared to the Atg regime, 3.7% vs. 12.2%. CONCLUSION LS cost benefits included lower amounts of gonadotrophin used and fewer injections. It is a viable alternative regime in producing comparable clinical PR at lower cost and less complication in ART.

Abstract
Aim: The mild ovarian stimulation protocol for in vitro fertilization (IVF) is carried out to minimize adverse side-effects as well as cost. While performing mild ovarian stimulation with a gonadotropin-releasing hormone (GnRH) antagonist, the pregnancy rate was examined in cases that exhibited a serum estradiol (E2) drop down. Methods: In this study, 174 patients who requested mild ovarian stimulation for IVF began clomiphene citrate on day 3 and recombinant follicle-stimulating hormone (FSH) on day 5 of their menstrual cycles. A GnRH antagonist was administered when the dominant follicle reached a diameter of 14 mm. Serum luteinizing hormone and estradiol were measured at the time of GnRH antagonist administration and at the time of human chorionic gonadotropin (hCG) injection. Pregnancy rates and implantation rates were compared between 24 cycles in which the E2 level fell at the time of hCG injection and 150 cycles in which it did not fall. Results: The pregnancy rate in the cases in which the E2 level fell (25% decrease) at the time of hCG injection was significantly lower than it was in the cases in which it did not fall (16.7 vs 41.0%). The implantation rate for the cases in which the E2 level fell was also lower than that of the control group (7.0 vs 31.0%). There was no significant difference in the number of good-quality embryos between the two groups. Conclusion: When performing the mild ovarian stimulation protocol, serum E2 should be followed. It is prudent to avoid embryo transfer in the same cycle in cases that exhibit E2 drop down. (Reprod Med Biol 2008; 7: 85-89).

Abstract
With identical pregnancy rates after elective single embryo transfer (ET) and double ET strategies consisting of three cycles of IVF or intracytoplasmic sperm injection (ICSI) plus transfers of thawed/frozen embryos if available, 46% of the women undergoing IVF/ICSI favor elective single ET. If elective single ET lowers pregnancy chances with 1%, 3%, or 5%, the percentage of women preferring elective single ET drops to 34%, 24%, and 15%, respectively. If four, five, or six cycles with elective single ET are needed to match the success rate of three cycles with double ET, the percentage of women with a preference for elective single ET drops from 46% to 40%, 36%, and 35% respectively.

Abstract
Over the last two decades, easier and less expensive stimulation treatments have been largely replaced by more complex and more demanding protocols. Since the mid-nineties, long-term gonadotrophin-releasing hormone agonist stimulation protocols have been widely used. Such lengthy expensive regimens are not free from short- and long-term risks and complications. Mild stimulation protocols reduce the mean number of days of stimulation, the total amount of gonadotrophins used and the mean number of oocytes retrieved. The proportion of high quality and euploid embryos seems to be higher compared with conventional stimulation protocols and the pregnancy rate per embryo transfer is comparable. Moreover, the reduced costs, the better tolerability for patients and the less time needed to complete an IVF cycle make mild approaches clinically and cost-effective over a given period of time. However, further prospective randomized studies are needed to compare cumulative pregnancy rates between the two protocols. Natural cycle IVF, with minimal stimulation, has been recently proposed as an alternative to conventional stimulation protocols in normo- and poor responder patients. Although acceptable results have been reported, further large prospective randomized studies are needed to better evaluate the efficacy of these minimal regimens compared with conventional stimulation approaches.

Abstract
Embryo transfer policy and luteal supplementation was reviewed, comparing literature data and the results from the Maribor IVF Centre. A retrospective analysis of 1024 cycles in patients undergoing IVF, intracytoplasmic sperm injection (ICSI) or testicular sperm aspiration in unstimulated cycles was carried out using four different approaches for cycle monitoring. This showed that the most successful protocol for monitoring was administration of human chorionic gonadotrophin (HCG) when serum oestradiol was >0.49 nmol/l and follicle diameter was at least 15 mm. The implantation rate per transferred embryo was higher when a blastocyst was transferred (42.8%) rather than a day-2 embryo (23.5%) in the same monitoring protocol. Analysis of the influence of patient age on the success of oocyte retrieval, oocyte fertilization, embryo transfer rate and delivery rate demonstrates that patient age does not influence the rate of positive oocyte retrieval or fertilization rate as much as it influences pregnancy rate per embryo transfer. The delivery rate per cycle was dramatically influenced by age in patients over 38 years. There is no clear evidence in the literature as to whether luteal phase support is necessary in natural cycles for IVF/ICSI. Comparing the data, a higher pregnancy rate was observed if HCG was administered after embryo transfer.

Abstract
OBJECTIVE To update clinicians on different gonadotropin regimens for ovarian stimulation for IVF including the use of urinary and recombinant gonadotropins, the value of added LH to FSH in the stimulation regimen, the use of GnRH agonists and antagonists, and the role of minimal stimulation protocols. DESIGN Literature review and critical analysis of major articles during the last five years on ovarian stimulation for IVF. CONCLUSION(S) Urinary and recombinant gonadotropins, for ovarian stimulation for IVF, are probably equally safe and effective. The higher cost for recombinant products limits their worldwide use in IVF. Conflicting data exist regarding the benefit of adding LH to FSH in the stimulation regimens. The use of different GnRH-agonists, of varying potency, may account for different levels of LH suppression. Adding LH should be considered in severe situations of LH suppression such as with the use of potent GnRH-agonists or when GnRH-antagonists are introduced during the course of stimulation. GnRH-antagonists provide advantages to patients in terms of fewer injections, shorter stimulation days, and avoidance of adverse effects of agonists. The incidence of ovarian hyperstimulation syndrome is probably less with antagonists compared to agonists, with the option to use an agonist as a surrogate LH surge. Fixed and early start of the antagonist is probably more effective than an individualized and late start. The earlier reported lower pregnancy rates with antagonists compared to agonists is not fully understood and needs to be continually monitored. Minimal stimulation protocols using a combination of clomiphene citrate and gonadotropins are attractive and should be considered in some patients owing to lower costs and acceptable success rates. The optimal stimulation protocol for IVF should be an individualized regimen based on the patient's ovarian physiology and prior IVF experience, if any.

Abstract
FSH is a glycoprotein hormone consisting of two peptide subunits. The role of FSH in folliculogenesis is well known: to stimulate the formation of a large pre-ovulatory follicle that, because of its FSH-dependent maturation, is capable of ovulation and forming a corpus luteum in response to the mid-cycle surge of LH. FSH is widely used in ovarian stimulation for assisted reproduction techniques. Ovarian stimulation protocols combine the use of human menopausal gonadotrophin, urinary FSH or recombinant FSH with gonadotrophin-releasing hormone (GnRH) agonists or antagonists in order to increase oocyte number and to avoid premature LH surge. Recently, the availability of recombinant LH has permitted new stimulation protocols, combining recombinant FSH, recombinant LH and GnRH antagonists. Due to the limitations of the new Italian law in terms of the number of oocytes that can be fertilized, protocols with a softer ovarian stimulation are now considered, reducing risk of ovarian hyperstimulation syndrome, multiple pregnancies and emotional and physical burdens on the patients. Long-acting FSH preparations are also under clinical study. Knowledge of the stereochemical three-dimensional structure of FSH and its receptor will allow the study of new non-peptide orally administered molecules that fit the FSH receptors.
