Abstract
Background
Polycystic ovary syndrome (PCOs) women usually exhibit a high luteinizing hormone (LH) and hypersensitivity to exogenous gonadotropins stimulation which is a tremendous risk to ovarian hyperstimulation syndrome (OHSS). Since the pathophysiology of PCOS is mysterious, an aetiological approach to the treatment is difficult and should be individually designed. These features affect the outcome of treatment including ovulation and success rate. Also, PCOS women who have difficulty conceiving, frequently experience substantial treatment burden, risk, and psychological distress. Recently, a renewed interest has emerged in patient-friendly, low-risk, and less costly IVF treatments. Our study proposed a new soft protocol in PCOS ovrian stimulation without prior pituitary desensitization followed by fresh embryo transfer. Patients and methods: a retrospective cohort study was conducted between January 2018 to December 2021, including 48 out of 325 women with PCOS who underwent gonadotropin-stimulated intrauterine insemination cycles but due to unexpectedly high response with risk of multiple pregnancies and OHSS, they had been shifted to a rescue IVF and fresh embryo transfer. The primary outcomes were biochemical pregnancy, implantation rate, clinical pregnancy, rate of miscarriage, OHSS, and multiple pregnancies. Secondary outcomes were the endocrinological profiles, gonadotropin dose, and duration of stimulation. This study aims to evaluate the outcomes in the conversion of high-response gonadotropin intrauterine insemination (IUI) cycles to “rescue” in vitro fertilization (IVF/fresh embryo transfer) regarding implantation rates, pregnancy rates, and ovarian hyperstimulation syndrome (OHSS).
Results
This study used a low dose gonadotropin injections (2.1 ± 1.4) for an average duration of (9.1 ± 1.2) and showed a high success pregnancy rate: biochemical pregnancies (56.2%), implantation rate (50.2%), clinical pregnancy rate (49.9%), and miscarriage rate (8.5%). Multiple pregnancies occurred in (6.6%) and OHSS(4.4%) only in a mild form.
Conclusion
Our study revealed that ovarian stimulation without prior pituitary suppression in high responders was feasible to improve the implantation rate and alleviate profound OHSS without compromising the pregnancy outcomes. This encourages all fertility specialists to implement this new protocol with expected high responders as an alternative to the conventional cycle segmentation protocol: GnRH agonist-antagonist IVF/freeze-all strategy.

Abstract
Purpose To assess the outcome of excess follicle aspiration before intrauterine insemination (EFABI) in intrauterine insemination (IUI) cycles with 4-6 follicles ≥14 mm. Methods A retrospective case-control study with 1559 patients undergoing IUI (donor and husband's sperm), of whom 86 underwent EFABI. We studied also an historical series of 2213 patients before EFABI implementation. For 3.5 years, all women undergoing IUI developing 4-6 follicles ≥14 mm were offered EFABI on the day of hCG administration. Pregnancy rates (PRs), multiple PRs, and adverse effects were measured. Results EFABI was associated with a similar multiple PR (17.8% vs 17.5% in non-EFABI cases), with no triplets in EFABI patients. Live birth rates were significantly higher in EFABI cycles in IUI overall (25.5% vs 15.2%). When considered separately, the performance of EFABI resulted in significantly increased live birth rates in IUI-donor cycles (32.5% vs 18.5%), whereas the differences in IUI-husband cycles (19.5% vs 12.9%) did not reach statistical significance. The PR was 21.2% during the EFABI implementation period and 19.4% in the pre-EFABI period. Conclusions EFABI in cycles in which 4-6 follicles reach ≥14 mm is a simple option that reduces cycle cancellation rates, results in higher PRs than cycles with 1-3 follicles, and lowers the risk of multiple pregnancy.

Abstract
Assisted reproductive technologies (ART) encompass fertility treatments, which involve manipulations of both oocyte and sperm in vitro. This chapter provides a brief overview of ART, including indications for treatment, ovarian reserve testing, selection of controlled ovarian hyperstimulation (COH) protocols, laboratory techniques of ART including in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI), embryo transfer techniques, and luteal phase support. This chapter also discusses potential complications of ART, namely ovarian hyperstimulation syndrome (OHSS) and multiple gestations, and the perinatal outcomes of ART.

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
BACKGROUND The aim of the study was to determine the efficacy of in vitro fertilization and embryo transfer (IVF-ET) in patients with hyper-response to ovulation induction for intrauterine insemination (IUI). METHODS Patients with polycystic ovary syndrome (PCOS) who were initially treated with IUI in our centre between Jan 2007 and Oct 2010 were retrospectively analyzed. The ovarian hyper-stimulation syndrome (OHSS) found in 50 patients was then treated with IVF-ET following informed consent. RESULTS The fresh transfer had 42 cycles and a total of 87 embryos were transferred. Urine pregnancy tests were positive in 15 patients and fetal heart beat was detected in 12 patients by transvaginal ultrasound, from which 3 patients had two fetuses, 2 patients had three fetuses, and 7 patients had a single fetus. The overall clinical pregnancy rate was 28.5% (12/42) for the fresh embryo transfer. A total of 21 cycles of frozen embryo transfer with up to 55 embryos were conducted for patients who were not pregnant at the end of fresh embryo transfer cycles or who did not receive fresh embryo transfer in the first place. Urine pregnancy tests were positive in 10 patients and fetal heart beat was detected in 8 patients. The clinical pregnancy rate was 38.1% (8/21) for frozen embryo transfer. CONCLUSION We conclude that IVF-ET is an effective method for patients with hyper-response to ovulation induction in IUI.

Abstract
Ovarian stimulation and intrauterine insemination (OS/IUI), a mainstay of current infertility therapy and a common antecedent to IVF, is a significant driver of the multiple births epidemic. Redress of this challenge, now marking its quarter centennial, will require a rethinking of current practice patterns. Herein we explore prospects for prevention, mitigation, and eventual resolution. We conclude that the multiple births attributable to OS/IUI may not be entirely preventable but that the outlook for their mitigation is promising, if in need of solidification. Specifically, we observe that low-dose (≤ 75 IU) gondotropin, clomiphene, and especially off-label letrozole regimens outperform high-dose (≥ 150 IU) gonadotropin counterparts in the gestational plurality category while maintaining comparable per-cycle pregnancy rates. Accordingly we recommend that, subject to appropriate exceptions, high-dose gonadotropin regimens be used sparingly and that whenever possible they be replaced with emerging alternatives. Finally, we posit that OS/IUI is not likely to be superseded by IVF absent further commoditization and thus greater affordability.

Abstract
OBJECTIVE To determine whether the use of GnRH antagonist in cycles converted from ovulation induction-IUI to IVF affects cycle outcome and pregnancy rates. DESIGN Retrospective cohort study. SETTING Academic research institution. PATIENT(S) One hundred eighty-two consecutive patients with ovulation induction-IUI to IVF conversions undergoing oocyte retrieval conducted at our institution from 2004 to 2006. INTERVENTION(S) The relation between observation of fetal heartbeat and GnRH antagonist exposure was evaluated with use of multivariable logistic regression. The difference in intermediate cycle outcomes by antagonist exposure was estimated with use of linear regression. MAIN OUTCOME MEASURE(S) Fetal cardiac activity on early ultrasound, intermediate cycle parameters. RESULT(S) For patients given treatment with a GnRH antagonist, the odds ratio for achieving pregnancy was 2.13 (95% confidence interval = 1.03-4.39) compared with untreated patients, independent of age and E(2) levels on day of hCG. Patients given antagonist had 1.6 more follicles and 2.1 more oocytes retrieved, 1.9 more mature oocytes, and 2.3 more fertilized oocytes, and the fertilization rate was 9.7% higher. CONCLUSION(S) Gonadotropin-releasing hormone antagonist use in ovulation induction-IUI to IVF conversions was associated with increased pregnancy rates and improved intermediate cycle parameters, controlled for age and E(2) levels on day of hCG. Addition of a GnRH antagonist should be considered in ovulation induction-IUI to IVF conversions.

Abstract
OBJECTIVE To review factors associated with high-order multiple births (HOMB) due to ovulation induction (OI) and the efficacy of strategies to reduce their occurrence. DESIGN Retrospective analysis of published studies of OI with intrauterine insemination (IUI) where patient and cycle characteristics were fully documented. RESULT(S) High-order multiple pregnancies (HOMP) were positively related to use of high doses of gonadotropin, number of 7-10 mm preovulatory follicles, and E(2), and inversely related to age and number of treatment cycles. Strategies successful in reducing HOMP include: use of clomiphene (CC) before gonadotropins, minimal gonadotropin doses, cancellation for more than three follicles >10-15 mm, and aspiration of excess follicles. Depending on the strategy used, 5%-20% of cycles may be canceled but HOMP rates can be less than 2% and pregnancy rates can average 10%-20% per cycle. Pregnancy rates per patient need not be reduced if low doses are continued for 4-6 cycles. CONCLUSION(S) High-order multiple pregnancies due to OI can be reduced to 2% or less by less aggressive stimulation without reducing overall chances of pregnancy for most patients.

Abstract
Solid organ transplantation can prolong the life of individuals with end-stage diseases that affect the kidney, liver, lung, heart, and pancreas. The improved survival of transplant recipients has led to increased attention on quality of life issues, including controlling fertility and having children. Perturbations of the hypothalamic-pituitary-ovarian axis in women with chronic renal failure or severe hepatic dysfunction result in anovulation and reduced fertility. Most often, fertility is restored with successful organ transplantation and good overall health. Although there are case reports of children born subsequent to assisted reproductive technologies (ART) in female transplant recipients, the approach to infertility in this population has not been described. Recognizing the unique medical, ethical, and psycho-social concerns involved in treating infertile female transplant recipients, reproductive endocrinologists must work with a multi-disciplinary team to ensure a successful pregnancy outcome without compromising graft function or maternal health. The primary goal of ART is a singleton pregnancy without complications, such as ovarian hyperstimulation syndrome, that pose greater risks in transplant recipients.

Abstract
Iatrogenic multiple pregnancy is the most significant complication of assisted reproductive technology (ART). Approximately half of all children born subsequent to ART result from a plural gestation. Furthermore, the majority of triplets and higher order births are the product of ART. The risks for multiple pregnancy vary with practice patterns and the techniques used to achieve pregnancy. Recognizing the potential for serious morbidity associated with multiple pregnancies, infertility specialists have developed strategies to reduce the complication of multiple pregnancies while maintaining acceptable pregnancy rates. Implementation of these refined practices has led to a reduction in the incidence of higher order multiple births, although the incidence of twins has yet to be minimized. Further reduction in the incidence of multiple births after ART necessitates a redefinition of success to emphasize the healthy singleton birth rate, rather than crude pregnancy rates.

Abstract
This review summarizes the existing evidence regarding intrauterine insemination (IUI) as a treatment for cervical hostility, male and unexplained subfertility. IUI in natural cycles has been proven effective in patients with cervical hostility and moderate male subfertility. IUI in cycles with mild ovarian hyperstimulation (MOH) should be the treatment of choice in couples with mild male subfertilty (average total motile sperm count above 10 million) and unexplained subfertilty. When MOH is applied, gonadotropins have been proven more effective compared with clomiphene citrate. Further large trials comparing clomiphene citrate with gonadotropins are mandatory. Prevention of multiple pregnancies in MOH/IUI programs is of paramount importance. A strategy with a low-dose step-up protocol and strict cancellation criteria is proposed. When multiple pregnancies are kept to a minimum, MOH/IUI is more cost-effective compared with in vitro fertilization and embryo transfer. Future research should focus on prediction models to predict the outcome of MOH/IUI treatment for individual couples before starting treatment.

Abstract
OBJECTIVE To evaluate superovulation (SOV) and IVF-ET cycles in which E2 levels were allowed to decrease to restrain rapid follicular growth and minimize the risk of ovarian hyperstimulation syndrome. DESIGN Retrospective series. SETTING Tertiary care infertility practice. PATIENT(S) Women who underwent SOV (n = 51) and IVF-ET (n = 93) treatment and who were at risk for OHSS. INTERVENTION(S) In SOV cycles, hMG was withheld (coasting) for >3 days before hCG administration, until follicular maturity was attained (> or = 3 follicles of > or = 18 mm) and E2 levels decreased. In IVF-ET cycles, either follicular maturity was attained before coasting (n = 63), allowing hCG administration after E2 levels decreased by >25%, or coasting occurred before follicular maturation (n = 30), necessitating the administration of additional hMG after coasting. MAIN OUTCOME MEASURE(S) Estradiol concentrations, follicle size, and pregnancy rates. RESULT(S) Estradiol concentrations usually rose for > or = 1 day after coasting began, then fell by > or = 25% while follicle numbers and mean diameters increased. No spontaneous LH surges occurred, although four SOV cycles were canceled because of excessive follicular development. Of the women who received hCG,11 of 47 (23% per cycle) conceived during SOV and 35 of 93 (37.6% per cycle) conceived during IVF-ET. Severe ovarian hyperstimulation syndrome developed in 1 woman who underwent IVF-ET. CONCLUSION(S) Coasting can safely rescue overstimulated SOV and IVF-ET cycles characterized by an excessive rise in E2 levels and/or numerous incompletely mature follicles.

Abstract
All assisted conception techniques are associated with an increase in the multiple pregnancy rate. Iatrogenic multiple births are increasing as the use of these technologies expands. The cornerstone of safe ovulation induction is careful ultrasound monitoring, with cancellation of cycles if excessive ovulation is expected. In in vitro fertilization (IVF) cycles, the main determinant of multiple pregnancy risk is the number of embryos replaced. The current move in IVF clinics is to reduce the risk of multiple pregnancy by reducing the number of embryos transferred. We would suggest a maximum of two embryos transferred to women under, for example, 39 years of age. Women of 39 years or over have a reduced chance of embryo implantation; they should be allowed the transfer of up to three embryos (the UK legal maximum).

Abstract
OBJECTIVE To avoid multiple pregnancies caused by ovulation induction. SETTING Infertile couples treated in the Women's Hospital and the Institute of Reproductive Medicine of the University of Münster, Münster, Germany. DESIGN The outcome of ovulation induction in patients in whom supernumerary ovarian follicles were aspirated transvaginally was compared with the outcome in patients in whom this intervention was not necessary. In a second randomized prospective study, the efficacy of a low dosage of gonadotropins was compared with a higher dosage. PATIENTS Two hundred twenty-seven couples suffering from male infertility, unexplained infertility, incipient ovarian failure, and polycystic ovaries. INTERVENTIONS Aspirations were performed if more than three follicles were sized > 14 mm. MAIN OUTCOME MEASURE Number of (multiple) pregnancies. RESULTS During 232 ovulation inductions, 127 aspirations of supernumerary follicles were performed (54.7%). The pregnancy rate (PR) in these cycles was similar to cycles in which aspirations were unnecessary (24.4% versus 21.9%). The efficacy of 75 units of FSH administered daily during the recruitment phase of follicular development was equivalent to 150 units of FSH (PR: 32.4% versus 31.6%), but supernumerary follicles were fewer (26.5% versus 76.3%). Six twins, two triplets (multiple PR: 10.4%), and no ovarian hyperstimulation syndrome occurred. CONCLUSIONS Transvaginal aspiration of supernumerary follicles does not reduce the PR in ovulation induction. Supernumerary follicles can be avoided by low-dose administration of gonadotropins without compromising the PR.

Abstract
OBJECTIVE To report an unexpected case of severe ovarian hyperstimulation syndrome (OHSS) and to compare E2 levels and number of follicles to other oocyte donors. SETTING Private assisted reproduction technology center. PATIENTS Healthy oocyte donors with normal menstrual cyclicity. INTERVENTIONS Prophylactic and therapeutic use of human serum albumin infusions. MAIN OUTCOME MEASURE The clinical development of signs and symptoms of severe OHSS. RESULTS More than 60% of other oocyte donors had higher E2 levels and 12% had higher number of follicles without associated OHSS. CONCLUSION The risk of developing severe OHSS cannot be predicted accurately to be low even in the absence of "risk factors."
