Abstract
OBJECTIVE hCG is commonly used as an ovulation trigger in IVF. Its usage is associated with OHSS. GnRH agonist is an alternative to hCG and is associated with reduced incidence of OHSS. This study compared the cycle outcomes of GnRH agonists with hCG as an ovulation trigger in IVF cycles. METHODS The medical notes of 209 IVF cycles receiving GnRH agonist and hCG as ovulation trigger over 18 months were reviewed in this retrospective study. The number and quality of mature oocytes, the number and quality of embryos, pregnancy rates, and outcomes were compared using Independent T-test or One-way ANOVA for normal distribution. The Mann-Whitney test or Kruskal-Wallis test was used for not normally distributed. p<0.05 was considered statistically significant. RESULTS The cycle outcomes of 107 GnRH agonist-trigger and 102 hCG-trigger were compared. The MII oocytes retrieved and 2PN count was significantly higher in the GnRH agonist trigger group (p<0.001). Clinical pregnancy rate and ongoing pregnancy were higher in the GnRH agonist trigger group but were not statistically significant. The GnRH agonist trigger group was associated with low OHSS than the hCG trigger group (n=2(1.9%) and n=12(11.8%) respectively, p=0.004). CONCLUSION GnRH agonist trigger is an option as a final maturation trigger in high-responder women undergoing IVF or ICSI cycles.

Kotlyar AM, Seifer DB. Women with PCOS who undergo IVF: a comprehensive review of therapeutic strategies for successful outcomes. Reprod Biol Endocrinol 2023; 21:70. [PMID: 37528417 PMCID: PMC10391774 DOI: 10.1186/s12958-023-01120-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 07/15/2023] [Indexed: 08/03/2023] Open
Abstract
Polycystic ovarian syndrome (PCOS) is a widespread syndrome that poses unique challenges and constraints to the field of assisted reproductive technology. This condition is the most common cause of anovulation among infertile couples. Debate exists over the best therapeutic course of action when patients with PCOS proceed to IVF. In this review, we evaluate the best-performing and safest methods of IVF preparation, ovarian stimulation, trigger method for maturation of stimulated egg growth, and planning for embryo transfer. Pre-IVF considerations include being aware of individual AMH and vitamin D levels as well as BMI prior to selecting an ovarian stimulation protocol. Numerous supplements such as myo-inositol complement the benefits of lifestyle change and may enhance IVF performance including oocyte yield and pregnancy rate. Concerning stimulation protocols, antagonist cycles with the judicious use of GnRH agonist trigger, pre-treatment with metformin and vitamin D repletion may help mitigate the accompanied risk of ovarian hyperstimulation syndrome (OHSS). Following ovarian stimulation, PCOS patients typically undergo programmed frozen embryo transfer (FET) cycles which are more conducive for women with irregular cycles, but likely carry a higher risk of hypertensive disorders of pregnancy. However, newer stimulated FET protocols using Letrozole may offer improved outcomes. Overall, patients with PCOS require careful individual tailoring of their IVF cycle to achieve optimal results.

Abstract
Background Luteal phase support (LPS) is an important part of assisted reproductive technology (ART), and adequate LPS is crucial for embryo implantation. At present, a great number of studies have put emphasis on an individualized approach to controlled ovarian stimulation (COS) and endometrium preparation of frozen- thawed embryo transfer (FET); However, not much attention has been devoted to the luteal phase and almost all ART cycles used similar LPS protocol bases on experience. Main body This review aims to concisely summarize individualized LPS protocols in fresh embryo transfer cycles with hCG trigger or GnRH-a trigger. The PubMed and Google Scholar databases were searched using the keywords: (luteal phase support or LPS) AND (assisted reproductive technology or ART or in vitro fertilization or IVF). We performed comprehensive literature searches in the English language describing the luteal phase support after ART, since 1978 and ending in May 2019. Recent studies have shown that many modified LPS programs were used in ART cycle. In the cycle using hCG for final oocyte maturation, the progesterone with or without low dose of hCG may be adequate to maintain pregnancy. In the cycle using GnRH-a for trigger, individualized low dose of hCG administration with or without progesterone was suggested. The optimal timing to start the LPS would be between 24 and 72 h after oocyte retrieval and should last at least until the pregnancy test is positive. Addition of E2 and the routes of progesterone administration bring no beneficial effect on the outcomes after ART. Conclusions Individualized LPS should be applied, according to the treatment protocol, the patients’ specific characteristics, and desires.

Reproductive Outcome After GnRH Agonist Triggering With Co-Administration of 1500 IU hCG on the Day of Oocyte Retrieval in High Responders: A Long-Term Retrospective Cohort Study. Front Endocrinol (Lausanne) 2022; 13:826411.

Abstract
UNLABELLED While triggering oocyte maturation with GnRH agonist (GnRHa) seems to be safe and effective in terms of the risk of developing OHSS and the number of metaphase II oocytes, it nevertheless results in luteal phase deficiency. To date, strategies have been developed in order to rescue defective luteal phase of GnRHa triggered cycles. Our study aimed to assess the reproductive outcome of GnRHa triggered cycles combined with modified luteal support (1500 IU hCG at the day of oocyte retrieval) in women with high ovarian response and to compare the outcome with hCG triggered cycles in GnRH antagonist IVF-ICSI procedures. A retrospective cohort database review of the results of GnRH antagonist IVF-ICSI cycles was conducted at a tertiary-care IVF center in Ljubljana, Slovenia. A total of 6126 cycles, performed from January 1, 2014, to December 31, 2020, were included in the final analysis. Final oocyte maturation was performed with either 5000, 6500, or 10,000 IU hCG (women with normal ovarian response) or 0.6 mg GnRHa (buserelin), supplemented with 1500 IU hCG on the day of oocyte retrieval (in women with high ovarian response). In cases of excessive ovarian response and/or high risk of OHSS luteal support was not introduced and all good quality blastocysts were frozen. According to significant differences in patients' age and the number of oocytes in the two groups, matching by age and number of oocytes was performed. No significant differences were observed regarding pregnancy rate per embryo transfer, rate of early pregnancy loss, and livebirth rate per pregnancy between the GnRHa and hCG trigger groups, respectively. A significant difference in the number of developed embryos and blastocysts, as well as the number of frozen blastocysts, was seen in favor of the GnRHa trigger. However, the birth weight in the GnRHa trigger group was significantly lower. CONCLUSION The results of our study support the use of GnRHa for final oocyte maturation in GnRH antagonist IVF cycles in women with high ovarian response. Luteal phase rescue was performed by co-administration of 1500 IU hCG on the day of oocyte retrieval and estradiol and progesterone supplementation. In our experience, such an approach results in a comparable reproductive outcome with hCG trigger group.

How frequent is severe ovarian hyperstimulation syndrome after GnRH agonist triggering in high-risk women? A systematic review and meta-analysis. Reprod Biomed Online 2020; 42:635-650.

Abstract
The aim of the present systematic review and meta-analysis was to assess the incidence of severe ovarian hyperstimulation syndrome (OHSS) after triggering of final oocyte maturation with gonadotrophin releasing hormone agonist (GnRHa) in high-risk women. The pooled incidence of severe OHSS in high-risk women who did not receive any form of luteal phase support was 0% (95% CI 0.0 to 0.0, I2 = 0%, random-effects model, 14 data sets, 983 women). The pooled incidence of severe OHSS in high-risk women in whom HCG was added to standard luteal phase support was 1% (95% CI 0.0 to 2.0, I2 = 27.02%, random-effects model, 10 data sets, 707 women). The incidence of severe OHSS in high-risk women triggered by a combination of GnRHa and HCG (dual triggering), who received standard luteal phase support, was 1% (95% CI 0.0 to 3.0, one study, 182 women). The incidence of severe OHSS in high-risk women, is not eliminated when HCG is administered either concomitantly with GnRHa (dual triggering), during the luteal phase after GnRHa triggering, or both. On the contrary, it is eliminated when no luteal support is administered.

The freeze-all strategy after IVF: which indications? Reprod Biomed Online 2020; 42:529-545.

Abstract
The freeze-all strategy is gaining popularity worldwide as an alternative to the conventional fresh embryo transfer. It consists of cryopreservation of the entire embryo cohort and the embryo transfer in a subsequent cycle that takes place separately from ovarian stimulation. The freeze-all strategy was initially a 'rescue' strategy for women at high risk of ovarian hyperstimulation syndrome; however, this approach has been extended to other indications as a scheduled strategy to improve implantation rates. This assumes that ovarian stimulation can alter endometrial receptivity in fresh cycles owing to the effect of supraphysiological levels of steroids on endometrial maturation. The procedure, however, has not been associated with increased live birth rates in all infertile couples, and concerns have been raised about the occurrence of several adverse perinatal outcomes. It is, therefore, crucial to identify in which subgroups of patients a freeze-all strategy could be beneficial. The aim of this review is to summarize current scientific research in this field to highlight potential indications for this strategy and to guide clinicians in their daily practice.

Abstract
BACKGROUND Strong evidence has suggested an important role of telomeres in meiosis, fertilization, and embryo development. PURPOSE To determine if sperm telomere length (STL) in sperm purified by differential gradient centrifugation followed by swim-up (selected STL) is correlated with sperm quality and clinical outcomes. METHODS Relative selected STL was assessed by quantitative polymerase chain reaction (Q-PCR) in 78 consecutive assisted reproductive technology (ART) treatments during 2017. Statistical analyses were performed in the totality of patients, and in normozoospermic and non-normozoospermic patients. These included correlations between selected STL and sperm quality parameters, embryological parameters (multivariable linear regression), and clinical parameters (multivariable logistic regression). RESULTS No significant correlations were found between selected STL and sperm quality in the total population. However, selected STL was significantly correlated with total sperm count (r = 0.361; P = 0.039) and sperm DNA fragmentation-post-acrosomal region pattern (r = - 0.464; P = 0.030) in normozoospermic patients. No relation was observed between selected STL and clinical outcomes in any clinical group. CONCLUSIONS As the correlations observed in normozoospermic patients were not representative of the whole heterogeneous population, differences in the sperm characteristics of the study population may lead to discrepant results when evaluating the association of STL with sperm quality. Since the total population selected STL was not related with sperm quality and with clinical outcomes, results do not support the use of selected STL measurement to evaluate the reproductive potential of the male patient or to predict the success rates of ART treatments.

Abstract
The introduction of gonadotrophin-releasing hormone agonist (GnRHa) trigger greatly impacted modern IVF treatment. Patients at low risk of ovarian hyperstimulation syndrome (OHSS) development, undergoing fresh embryo transfer and GnRHa trigger can be offered a virtually OHSS-free treatment with non-inferior reproductive outcomes by using a modified luteal phase support in terms of small boluses of human chorionic gonadotrophin (hCG), daily recombinant luteinizing hormone LH (rLH) or GnRHa. In the OHSS risk patient, GnRHa trigger can safely be performed, followed by a 'freeze-all' policy with a minimal risk of OHSS development and high live birth rates in the subsequent frozen embryo transfer cycle. Importantly, GnRHa trigger opened the 'black box' of the luteal phase, promoting research in the most optimal steroid levels during the luteal phase. GnRHa trigger allows high-dose gonadotropin stimulation to achieve the optimal number of oocytes and embryos needed to ensure the highest chance of live birth. This review thoroughly discusses how the GnRHa trigger concept adds safety and efficacy to modern IVF in terms of OHSS prevention. Furthermore, the optimal luteal phase management after GnRHa trigger in fresh embryo transfer cycles is discussed.

Abstract
PURPOSE To assess whether GnRH agonist trigger impacts the implantation potential of euploid embryos. METHODS Retrospective cohort study done at an academic IVF center evaluating frozen-thawed embryo transfer (FET) cycles in which single-euploid blastocysts were transferred between 2014 and 2019. All embryos were generated in an IVF cycle which used GnRHa or hCG trigger and then were transferred in a programmed or natural FET cycle. Only the first FET cycle was included for each patient. Primary outcome was ongoing pregnancy rate or live birth rate (OPR/LBR). Secondary outcomes were implantation rate (IR), clinical pregnancy rate (CPR), clinical loss rate (CLR), and multiple pregnancy rate (MPR). Logistic regression was performed to control for confounding variables. A p value of < 0.05 was considered statistically significant. RESULTS Two hundred sixty-three FET cycles were included for analysis (GnRHa = 145; hCG = 118). The GnRHa group was significantly younger (35.2 vs. 37.5 years) and had higher AMH values (4.50 ng/ml vs. 2.03 ng/ml) than the hCG group, respectively (p < 0.05). There was no significant difference in OPR/LBR (64.1% (93/145) vs. 65.3% (77/118); p = 0.90) between the GnRHa and hCG groups, respectively. There was also no significant difference in IR, CPR, CLR, or MPR between groups. After controlling for confounding variables, the adjusted odds ratio for OPR/LBR was 0.941 (95% CI, 0.534-1.658); p = 0.83) comparing GnRHa to hCG. Pregnancy outcomes did not significantly differ when groups were stratified by age (< 35 vs. > 35 years old). CONCLUSIONS Our findings confirm that euploid embryos created after hCG or GnRHa trigger have the same potential for pregnancy.

Abstract
The aim of this review is to provide qualitative evidence-based synthesis regarding efficacy of luteal-phase support on fertility outcome in women undergoing in vitro fertilization (IVF) with respect to clinical or live birth rates and pregnancy loss rates. Although the need of luteal phase support in IVF/ICSI cycles is well-known, the optimal start, dosage, route and the duration of the luteal phase support is still subject of debate. Data suggest that the optimal period to start with the luteal phase support would be between 24-72 hours after oocyte-retrieval and should continue at least until a positive pregnancy test is achieved. However, the majority of IVF-centers worldwide provide progesterone support up to 8 weeks of pregnancy. Among the well-established routes of luteal support, oral dydrogesterone and subcutaneous progesterone represent new and interesting routes of progesterone administration. The current studies support these routes of progesterone administration use in terms of comparable pregnancy rates and pregnancy loss rates to vaginal and intramuscular progesterone. Furthermore, the acceptance and tolerability among patients seems to be even better. In the frozen-thawed embryo transfer, dydrogesterone and vaginal progesterone are not effective as monotherapy treatments; however, when combined there is no reason to avoid one or the other in this setting.

[PMID: 31508563 PMCID: PMC6719513 DOI: 10.18502/ijrm.v17i6.4809] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2018] [Revised: 11/03/2018] [Accepted: 02/06/2019] [Indexed: 11/24/2022] Open
Abstract
Background Clomiphene citrate (CC) is one of the widely used drugs as an ovulation stimulant, but its adverse effects on the endometrium results in lowering down the pregnancy rate. Endometrium CD98 is also important in the process of implantation. Objective To evaluate the immunohistochemistry expression levels of endometrial CD98 following injection of CC with and without Human chorionic gonadotropin (HCG) in ovariectomized and non-ovariectomized rats. Materials and Methods Seventy two (12-14 wk old) female Wistar rats were randomly divided into two groups (n = 36): (a) ovariectomized and (b) non-ovariectomized. Each group was further divided into six subgroups (n = 6/each): (1) CC 10 mg/kg, (2) CC 20 mg/kg, (3) HCG, (4) CC 10 mg/kg with HCG, (5) CC 20 mg/kg with HCG, and (6) control. The experimental subgroups received a single dose of CC (daily, five days) and HCG (after the last injection of CC) alone or in combination. Immunohistochemistry staining was performed on paraffin-embedded endometrial tissues to evaluate the expression levels of CD98. Results Animals undergoing ovariectomy presented a significantly lower expression level of endometrial CD98 (p < 0.001) when compared with non-ovariectomized in the same condition that groups were subdivided. There was also a dose-dependent reduction (p < 0.001) in the expression of CD98 in non-ovariectomized subgroups when compared with control group. In addition, injection of HCG following treatment with CC improved its expression. Conclusion It was concluded that CC impairs CD98 expression in endometrium and this impairment is intensified with the removal of the ovary. Also, an injection of HCG following treatment with CC can slightly improve the expression of CD98.

Comparison of Oocyte Maturation Trigger Using Follicle Stimulating Hormone Plus Human Chorionic Gonadotropin versus hCG Alone in Assisted Reproduction Technology Cycles. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2019; 13:102-107.

Abstract
Background The goal of this study was to investigate oocyte maturation, fertilization and pregnancy rates among
infertile women, by concomitant follicle stimulating hormone (FSH) administration at the time of human chorionic
gonadotropin (hCG) trigger, compared to hCG trigger alone. Materials and Methods In this prospective randomized controlled trial, 109 infertile women between the ages of
20 and 40 years, received gonadotropin-releasing hormone (GnRH) antagonist and fresh embryo transfer. Following
the procedure, the subjects were randomly divided into two groups on the oocyte-triggering day. In the experimental
group, final oocyte maturation was achieved by 5000 IU hCG plus 450 IU FSH. In the control group, however, oocyte
triggering was performed by 5000 IU hCG, only. The primary outcome was clinical pregnancy and the secondary out-
comes included oocyte recovery rate, oocyte maturity rate, fertilization proportion rate, fertilization rate, implantation
rate and chemical pregnancy rate. Results Fifty-four women were appointed to the group with the FSH bolus injection at the time of hCG trigger and
55 women were assigned to the hCG alone group. Women in the FSH group had a significantly higher metaphase II
(MII) oocyte (7.17 ± 3.50 vs. 5.87 ± 3.19), 2 pronuclear embryos (2PNs) (5.44 ± 3.20 vs. 3.74 ± 2.30) and total em-
bryos (4.57 ± 2.82 vs. 3.29 ± 2.13) compared to hCG alone group, respectively. Furthermore, fertilization rate (0.75
± 0.19 vs. 0.68 ± 0.25), implantation rate (14.2 vs. 8.5%) as well as clinical (27.9 vs. 15.9%) and chemical (32.6 vs.
20.5%) pregnancy rates were higher in the FSH group, but no statistically significant difference was found (P>0.05). Conclusion Combination of FSH and hCG for oocyte triggering improves oocyte maturity and fertilization propor-
tion rates without increasing the chance of implantation, chemical and clinical pregnancy rates (Registration number:
IRCT2017082724512N5).

Abstract
Objectives: To compare the live birth rates and moderate/severe ovarian hyperstimulation syndrome (OHSS) rates of 2 different approaches using gonadotropin-releasing hormone (GnRH) agonist triggering in high responder women. Methods: A retrospective cohort study was performed to evaluate intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) outcomes in high responder women who underwent ovulation induction with a GnRH antagonist protocol between April 2011 and March 2015. In group 1 (n=74), GnRH agonist was used for ovulation triggering with the concomitant use of 1500 IU of urinary human chorionic gonadotropin (hCG) immediately after oocyte retrieval followed by fresh ET and standard luteal support. In group 2 (n=48), GnRH agonist was used for triggering after freezing all embryos and subsequent frozen/thawed embryo transfer (FET); this approach is considered the “freeze-all” approach. Results: Baseline characteristics were similar between the groups. The clinical pregnancy rates for group 1 was 45.9% and group 2 was 43.8% (p=0.812, chi-squared test) and live birth rates for group 1 was 40.5% and for group 2 41.7% (p=0.902, chi-squared test) were comparable between groups. In group 1, late-onset OHSS was observed (one severe case and one moderate case) in 2 patients (2.7%). In group 2, none of the patients experienced moderate/severe OHSS. Conclusion: The live birth rate with GnRH agonist triggering and concomitant use of 1500 IU of hCG immediately after oocyte retrieval was similar to that obtained with the freeze-all approach and FET in a subsequent cycle. The administration of a low dose of hCG in GnRH agonist trigger cycles caused moderate/severe OHSS in 2.7% of the patients.

Abstract
In this paper, a retrospective cohort study was conducted to the high ovarian responders in GnRH-antagonist protocols of IVF/ICSI cycles. The purpose of the study is to investigate whether dual triggering of final oocyte maturation with a combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (HCG) can improve the clinical outcome compared with traditional dose (10000IU) HCG trigger and low-dose (8000IU) HCG trigger for high ovarian responders in GnRH-antagonist in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) cycles. Our study included 226 couples with high ovarian responders in GnRH-antagonist protocols of IVF/ICSI cycles. Standard dosage of HCG trigger (10000 IU of recombinant HCG) versus dual trigger (0.2 mg of triptorelin and 2000 IU of recombinant HCG) and low-dose HCG trigger (8000IU of recombinant HCG) were used for final oocyte maturation. Our main outcome measures were high quality embryo rate, the number of usable embryos, the risk of OHSS, duration of hospitalization and incidence rate of complications. Our evidence demonstrated that dual trigger is capable of preventing severe OHSS while still maintaining excellent high quality embryo rate in in high ovarian responders of GnRH-antagonist protocols.

Abstract
OBJECTIVE To compare the results obtained with two different GnRH agonist dosages: 0.3mg versus 0.4mg to trigger ovulation in oocyte donor cycles. METHODS Experimental controlled randomized trial including 40 patients from a private practice center. The patients were randomized into two groups. Group A received a single dose of Triptorelin 0.3mg (Decapeptyl®) 36hours before pick-up. Group B patients received Triptorelin 0.4mg (Decapeptyl®) before pick-up to final oocyte maturation. We evaluated the total number of oocytes collected, the number of mature oocytes and total days of ovarian stimulation. RESULTS The average of total collected oocytes were 16 (Group A) versus 15 (Group B), and the mean number of mature oocytes were 13 versus 12 respectively. The only variable showing a difference was the percentage of mature oocytes, which was greater in Group A, resulting in 84.6%, in contrast with those treated with 0.4mg of Triptorelin (78.6%), although these differences were not statistical significant (p=0.35). Days of stimulation did not differ between groups. No cases of empty follicle syndrome were reported. CONCLUSIONS We found that an increase from 0.3 to 0.4mg of triptorelin in an oocyte donation program might not improve outcomes. Nevertheless, more studies might be necessary, not only in oocyte donors but in sterile women as well, to evaluate how GnRH agonist dosage could affect the results among other factors.

GnRH agonist with low-dose hCG (dual trigger) is associated with higher risk of severe ovarian hyperstimulation syndrome compared to GnRH agonist alone. J Assist Reprod Genet 2016; 33:1175-84.

Abstract
PURPOSE The purpose of this study was to compare rates of ovarian hyperstimulation syndrome (OHSS) after using gonadotropin-releasing hormone agonists (GnRHa) alone and GnRHa in combination with low-dose human chorionic gonadotropin (hCG, dual trigger) for final oocyte maturation in women undergoing controlled ovarian hyperstimulation (COH). METHODS A retrospective cohort study was conducted at an academic center. Study population included 108 women who received GnRHa trigger and 66 women who received dual trigger (GnRHa + low-dose [1000 IU] hCG trigger). The main outcome measure was OHSS. Secondary outcomes included total oocyte yield and oocyte maturity. RESULTS The incidence of early OHSS was significantly higher after dual trigger than GnRHa trigger (8.6 vs 0 %). Moreover, four of the six patients that developed OHSS developed severe OHSS. Logistic modeling revealed that the combination of age, BMI, baseline AFC, and E2 >4000 pg/mL was predictive of OHSS with an area under the receiver operating characteristic curve of 0.84 and was superior to each factor alone. Adjusted analyses revealed that dual trigger was associated with a higher number of total oocytes (adjusted OR 1.27; 95 % confidence interval, 1.18, 1.38) and percentage of mature oocytes (AOR 1.10; 95 % confidence interval, 1.03, 1.17) obtained compared to GnRHa trigger alone. CONCLUSIONS Dual trigger for final oocyte maturation using GnRHa and low-dose hCG is associated with a significantly increased risk of severe OHSS compared to GnRH alone. However, dual trigger may be associated with a modest increase in oocyte yield, both in terms of number and maturity.

Abstract
PURPOSE The study aimed to describe the ultrastructure of two human mature oocyte intracytoplasmic dysmorphisms, the bull-eye inclusion and the granular vacuole, with evaluation of clinical outcomes after intracytoplasmic sperm injection (ICSI) treatment. METHODS We retrospectively evaluated 4099 consecutive ICSI cycles during the period 2003-2013. Three groups were compared: controls, those with a bulls-eye inclusion, and those with granular vacuoles. Oocyte dysmorphisms were evaluated by transmission electron microscopy and in situ fluorescence hybridization (FISH). Detailed data on demographic and stimulation characteristics, as well as on embryological, clinical, and newborn outcomes, are fully presented. RESULTS The bull-eye inclusion is a prominent smooth round structure containing trapped vesicles, being surrounded by lipid droplets. The presence of this dysmorphism in the oocyte cohort had no clinical impact except when transferred embryos were exclusively derived from dysmorphism oocytes. The granular vacuole is delimited by a discontinuous double membrane and contains lipid droplets and vesicles. As FISH analysis revealed the presence of chromosomes, they probably represent pyknotic nuclei. The presence of this dysmorphism in the oocyte cohort had no clinical impact except when at least one transferred embryo was derived from dimorphic oocytes. CONCLUSIONS Poor clinical outcomes were observed with transfer of embryos derived from dysmorphism oocytes, although without causing gestation or newborn problems. The bull-eye inclusion and granular vacuoles may thus be new prognostic factors for clinical outcomes.

Abstract
BACKGROUND Gonadotropin-releasing hormone (GnRH) agonist triggering plus 1,500 IU human chorionic gonadotropin (hCG) supplementation protocol was previously claimed effective in reducing the ovarian hyperstimulation syndrome (OHSS) incidence in high responders. METHODS This retrospective study included women with polycystic ovarian (PCO) morphology who were at high risk of OHSS and were given the GnRH agonist trigger plus hCG luteal support protocol in a single center. RESULTS The mean peak estradiol level was 5,336 ± 2,341 (1,187 - 19,746) pg/mL. The mean number of follicles > 12 mm on the day of trigger was 22 ± 7 (9 - 51). A total of 88 cycles were undertaken. Sixty-three (71.5%) women underwent fresh embryo transfer. Fresh embryo transfer was canceled in 21 (23.8%) and embryo transfer was canceled in four (4.5%) women. The overall clinical pregnancy rate was 46.4% per started cycle. A total of 12 (13.6%) patients developed OHSS. "Freeze-all" policy did not attenuate OHSS in four patients, and three of these patients developed OHSS despite 1,500 IU hCG was not administered. CONCLUSION We conclude that OHSS may still occur with the use of a GnRH agonist trigger combined with low-dose hCG supplementation protocol in women with polycystic ovary syndrome (PCOS) or PCO morphology. Furthermore, we also conclude that "freeze-all" policy also will not completely eliminate OHSS development in high-risk women.

Abstract
PURPOSE OF REVIEW Ovarian hyperstimulation syndrome (OHSS) complicates a considerable part of stimulated in-vitro fertilization (IVF) cycles and is a potential iatrogenic cause of death in otherwise healthy women undergoing fertility treatment. The triggering factor of OHSS is the widespread use of human chorionic gonadotropin (hCG) to induce final oocyte maturation. The aim of this review is to summarize different approaches available, using alternative triggering protocols such as gonadotropin-releasing hormone agonist (GnRHa) or kisspeptin for final oocyte maturation. RECENT FINDINGS According to the latest European Society of Human Reproduction and Embryology report, the incidence of OHSS ranges from 0.18 to 1.40% in European countries. However, OHSS is still subject to substantial underreporting. New triggering protocols using GnRHa have shown to be similar to the gold standard hCG-trigger with regard to the reproductive outcome, but with a significant decrease in - and almost elimination of - OHSS. Lately, promising results have been reported for the use of kisspeptin to induce final oocyte maturation. Although until now no study has been performed in an OHSS risk population, theoretically, the risk of OHSS development might be even further reduced after kisspeptin trigger. SUMMARY GnRHa trigger is currently the best tool we have to prevent OHSS and at the same time maintain good reproductive outcomes. Future research will explore the safety and efficacy of kisspeptin trigger.

Abstract
Gonadotrophin releasing hormone agonist (GnRHa) trigger is effective in the induction of oocyte maturation and prevention of ovarian hyperstimulation syndrome during IVF treatment. This trigger concept, however, results in early corpora lutea demise and consequently luteal phase dysfunction and impaired endometrial receptivity. The aim of this strenghths, weaknesses, opportunities and threats analysis was to summarize the progress made over the past 15 years to optimize ongoing pregnancy rates after GnRHa trigger. The advantages and potential drawbacks of this type of triggering are reviewed. The current approach to the management of GnRHa trigger in autologous cycles is based on the peak serum oestradiol level or follicle number and aims at a fresh embryo transfer or a segmentation approach with elective cryopreservation policy. We recommend intensive luteal support with transdermal oestradiol and intramuscular progesterone alone if peak serum oestradiol is 4000 or more pg/ml after GnRHa trigger or dual trigger with GnRHa and HCG 1000 IU if peak serum oestradiol is less than 4000 pg/mL. On the contrary, we recommend HCG 1500 IU 35 h after GnRHa trigger if there are less than 25 follicles, or freeze all oocytes or embryos if there are over 25 follicles.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Infertility is a prevalent presenting feature of PCOS, and approximately 75% of these women suffer infertility due to anovulation. Lifestyle modification is considered the first-line treatment and is associated with improved endocrine profile. Clomiphene citrate (CC) should be considered as the first line pharmacologic therapy for ovulation induction. In women who are CC resistant, second-line treatment should be considered, as adding metformin, laparoscopic ovarian drilling or treatment with gonadotropins. In CC treatment failure, Letrozole could be an alternative or treatment with gonadotropins. IVF is considered the third-line treatment; the ‘short’, antagonist-based protocol is the preferred option for PCOS patients, as it is associated with lower risk of developing ovarian hyperstimulation syndrome (specifically by using a gonadotropin-releasing hormone agonist as ovulation trigger), but with comparable outcomes as the long protocol.

Abstract
OBJECTIVE To determine the optimal GnRH agonist dose for triggering of oocyte maturation in oocyte donors. DESIGN Single-center, randomized, parallel, investigator-blinded trial. SETTING IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam. PATIENT(S) One hundred sixty-five oocyte donors (aged 18-35 years, body mass index [BMI] <28 kg/m(2), antimüllerian hormone level >1.25 ng/mL, and antral follicle count ≥6). INTERVENTION(S) Ovulation trigger with 0.2, 0.3, or 0.4 mg triptorelin in a GnRH antagonist cycle. MAIN OUTCOME MEASURE(S) The primary end point was number of metaphase II oocytes. Secondary end points were fertilization and cleavage rates, number of embryos and top-quality embryos, steroid levels, ovarian volume, and ongoing pregnancy rate (PR) in recipients. RESULT(S) There were no significant differences between the triptorelin 0.2, 0.3, and 0.4 mg trigger groups with respect to number of metaphase II oocytes (16.0 ± 8.5, 15.9 ± 7.8, and 14.7 ± 8.4, respectively), embryos (13.2 ± 7.8, 11.7 ± 6.9, 11.8 ± 7.0), and number of top-quality embryos (3.8 ± 2.9, 3.6 ± 3.0, 4.1 ± 3.0). Luteinizing hormone levels at 24 hours and 36 hours after trigger was significantly higher with triptorelin 0.4 mg versus 0.2 mg and 0.3 mg (9.8 ± 7.1 IU/L vs. 7.3 ± 4.1 IU/L and 7.2 ± 3.7 IU/L, respectively; 4.6 ± 3.2 IU/L vs. 3.2 ± 2.3 IU/L and 3.3 ± 2.1 IU/L, respectively. Progesterone level at oocyte pick-up +6 days was significantly higher in the 0.4-mg group (2.2 ± 3.7 ng/ml) versus 0.2 mg (1.1 ± 1.0 ng/ml) and 0.3 mg (1.2 ± 1.6 ng/ml). One patient developed early-onset severe ovarian hyperstimulation syndrome (OHSS). CONCLUSION(S) No significant differences between triptorelin doses of 0.2, 0.3, and 0.4 mg used for ovulation trigger in oocyte donors were seen with regard to the number of mature oocytes and top-quality embryos. CLINICAL TRIAL REGISTRATION NUMBER NCT02208986.

Abstract
Ovarian follicular responsiveness to controlled ovarian hyperstimulation (COH) with gonadotropins is extremely variable between individual patients, and even from cycle to cycle for the same patient. High responder patients are characterized by an exaggerated response to gonadotropin administration, accompanied by a higher risk for ovarian hyperstimulation syndrome (OHSS). In spite of its importance, the literature regarding high responders is characterized by heterogeneous classification methodologies. A clear separation should be drawn between risk factors for a high ovarian response and the actual response exhibited by a patient to stimulation. Similarly, it is important to distinguish between high ovarian response and development of clinically significant OHSS. In this article we: (1) review recent publications pertaining to the identification and clinical management of high responders, (2) propose an integrated clinical model to differentiate sub-groups within this population based on this review, and (3) suggest specific protocols for each sub-group. The model is based on a chronological patient assessment in an effort to target treatment based on the specific clinical circumstances. It is our hope that the algorithm we have developed will assist clinicians to supply targeted and precise treatments in order to achieve a favorable reproductive outcome with minimum complications for each patient.

Abstract
BACKGROUND Although a large number of studies have been dedicated to ovarian hyperstimulation syndrome (OHSS) none gave full embryological and clinical outcomes comparing oocyte trigger with human chorionic gonadotrophin (HCG) versus with a gonadotrophin-releasing hormone (GnRH) agonist (Buserelin) in cases with suspicious OHSS. The aim of the present study was thus to analyze 4894 consecutive assisted reproductive treatment cycles to undercover associated risk factors for development of OHSS, and the effects of the use of Buserelin as ovulation trigger on embryological and clinical outcomes. METHODS In the 51 cases that developed OHSS, ovulation trigger was performed with HCG as indicators were not suspicious for OHSS. These were compared against two types of groups: 71 cases where Buserelin was used for ovulation induction due to suspicious development of OHSS; and those remaining 4772 cases where ovulation trigger was currently performed with HCG (control). RESULTS Of the cases treated with Buserelin the oocyte maturation rate and the ongoing pregnancy rate were significantly lower, with higher rates of ectopic pregnancy and newborn malformations, but none developed OHSS. Of the OHSS cases, 23 needed hospitalization, with no major complications. CONCLUSIONS Young age, lower time of infertility, lower basal follicle stimulating hormone levels, higher number of cases with female factor and polycystic ovarian syndrome, high number of follicles and higher estradiol concentrations were the risk factors found associated with OHSS. Cases with OHSS also presented higher follicle count but the estradiol levels were within the normal range. It thus remains to develop more strict criteria to avoid all cases with OHSS.

Abstract
Gonadotropin-releasing hormone agonists (GnRHa) have gained increasing attention in the last decade as an alternative trigger for oocyte maturation in patients at high risk for ovarian hyperstimulation syndrome (OHSS). They provide a short luteinizing hormone (LH) peak that limits the production of vascular endothelial growth factor, which is the key mediator leading to increased vascular permeability, the hallmark of OHSS. Initial studies showed similar oocyte yield and embryo quality compared with conventional human chorionic gonadotropin (hCG) triggering; however, lower pregnancy rates and higher miscarriage rates were alarming in GnRHa triggered groups. Therefore, two approaches have been implemented to rescue the luteal phase in fresh transfers. Intensive luteal phase support (iLPS) involves administiration of high doses of progesterone and estrogen and active patient monitoring. iLPS has been shown to provide satisfactory fertilization and clinical pregnancy rates, and to be especially useful in patients with high endogenous LH levels, such as in polycystic ovary syndrome. The other method for luteal phase rescue is low-dose hCG administiration 35 hours after GnRHa trigger. Likewise, this method results in statistically similar ongoing pregnancy rates (although slightly lower than) to those of hCG triggered cycles. GnRHa triggering decreased OHSS rates dramatically, however, none of the rescue methods prevent OHSS totally. Cases were reported even in patients who underwent cryopreservation and did not receive hCG. GnRH triggering induces a follicle stimulating hormone (FSH) surge, similar to natural cycles. Its possible benefits have been investigated and dual triggering, GnRHa trigger accompanied by a simultaneous low-dose hCG injection, has produced promising results that urge further exploration. Last of all, GnRHa triggering is useful in fertility preservation cycles in patients with hormone sensitive tumors. In conclusion, GnRHa triggering accompanied by appropriate luteal phase rescue protocols is a relatively safe option for patients at high risk for OHSS.

Abstract
Background. The aim of this pilot study was to evaluate intranasal buserelin for luteal phase support and compare its efficacy with standard vaginal progesterone in IVF/ICSI antagonist cycles. Methods. This is a prospective, randomized, open, parallel group study. Forty patients underwent ovarian hyperstimulation with human menopausal gonadotropin under pituitary inhibition with gonadotropin-releasing hormone antagonist, while ovulation trigger and luteal support were achieved using intranasal GnRH agonist (group A). Twenty patients had their cycle downregulated with buserelin and stimulated with hMG, while ovulation trigger was achieved using 10,000 IU human chorionic gonadotropin with luteal support by intravaginal progesterone (group B). Results. No difference was observed in estradiol levels. Progesterone levels on day 5 were significantly lower in group A. However, significantly higher levels of luteinizing hormone were observed in group A during the entire luteal phase. Pregnancy rates (31.4% versus 22.2%), implantation rates (22% versus 15.4%), and clinical pregnancy rates (25.7% versus 16.7%) were not statistically different between groups, although a trend towards higher rates was observed in group A. No luteal phase lasting less than 10 days was recorded in either group. Conclusion. Intranasal administration of buserelin is effective for providing luteal phase support in IVF/ICSI antagonist protocols.

Abstract
CONTEXT Efficacy of gonadotropin releasing hormone agonists (GnRH-a) for ovulation in high-responders. AIMS The aim of the current study is to compare the impact of different GnRH-a doses for the final oocyte maturation on cycle outcomes and ovarian hyperstimulation syndrome (OHSS) rates in high-responder patients undergoing ovarian stimulation. SETTINGS AND DESIGNS Electronic medical records of a private in vitro fertilization center, a retrospective analysis. SUBJECTS AND METHODS A total of 77 high-responder cases were detected receiving GnRH-a. Group I consisted of 38 patients who received 1 mg of agonist and Group II consisted of 39 patients who received 2 mg of agonist. STATISTICAL ANALYSIS In order to compare groups, Student's t-test, Mann-Whitney U-test, Pearson's Chi-square test or Fisher's exact test were used where appropriate. A P < 0.05 was considered as statistically significant. RESULTS Number of retrieved oocytes (17.5 vs. 15.0, P = 0.510), implantation rates (46% vs. 55.1%, P = 0.419) and clinical pregnancy rates (42.1% vs. 38.5%, P = 0.744) were similar among groups. There were no mild or severe OHSS cases detected in Group I. Only 1 mild OHSS case was detected in Group II. CONCLUSION A volume of 1 or 2 mg leuprolide acetate yields similar outcomes when used for the final oocyte maturation in high-responder patients.

Abstract
Gonadotropin releasing hormone agonist triggers are very effective in eliminating early-onset ovarian hyperstimulation syndrome (OHSS). However, in most studies they result in inferior pregnancy rates compared to hCG triggers in fresh autologous transfers. This is not due to an effect on embryo quality but rather due to inadequate corpus luteum formation and a defective luteal phase causing poor implantation. Intensive and adjusted steroid support or low-dose hCG may correct this. Late-onset OHSS is eliminated by using a freeze-all strategy. Pregnancy rates after transfer of thawed vitrified embryos are consistently high. A strategy combining a gonadotropin releasing hormone agonist trigger with vitrification of all embryos has been proposed as a means of achieving a truly OHSS-free clinic.

Abstract
All IVF-ICSI cycles carried out between October 2009 and October 2012 using GnRH agonist (GnRHa) ovulation trigger (n = 62) followed by a single dose of HCG plus progesterone and oestradiol in the luteal phase because of anticipated ovarian hypertsimulation were retrospectively compared with historic control cycles using HCG trigger (n = 29) and standard luteal phase support. Women's mean age, body mass index, anti-Müllerian hormone, FSH, LH, starting and total stimulation dose, number of follicles, oocytes, embryos, fertilization, implantation, polycystic ovary syndrome, ICSI, live birth and ongoing pregnancy rates per embryo transfer were similar (GnRHa 40.7% versus HCG 35.0%). For each started cycle, GnRHa resulted in 11.4% higher (statistically non-significant) live birth and ongoing pregnancy rate (OR 1.73, CI 0.64 to 4.69), with a similar difference for double-embryo transfers (OR 1.62, CI 0.44 to 6.38) and less need for freezing all embryos (9.7% versus 27.6%; P = 0.04). Incidence of mild-to-moderate OHSS was 16.2% with GnRHa trigger and 31.0% with HCG trigger) and no severe OHSS in the former. The addition of single low-dose HCG in the luteal phase after GnRHa trigger for suspected high-responders reduced the incidence of OHSS with good clinical outcomes, compared with HCG trigger.

Abstract
OBJECTIVE To evaluate the efficacy and safety of ovulation triggering by agonists in antagonists IVF cycles with fresh embryo transfer in modulating low HCG dose for luteal phase support in patients at risk of ovarian hyperstimulation syndrome (OHSS). PATIENTS AND METHODS In an observational study from September 2011 to March 2013, we triggered with agonist 107 cycles with OHSS risk, we initially triggered 39 cycles with 2 doses of Triptorelin 0.1 mg. Injection of 1500 IU HCG was performed one hour after the pick up and a second injection of 1500 IU was made 5 days later (group 1) combined with 400 mg of natural progesterone vaginally. In the following 68 cycles we removed the second HCG injection and increased to 600 mg vaginal progesterone associated with E2 4 mg orally (group 2). RESULTS Group 1: the ongoing pregnancy rate and birth rate in fresh cycle is respectively 37.1% and 34.3% and the cumulative ongoing pregnancy rate and birth rate per patient is 43.6% and 41%. We recorded three late onset OHSS in pregnant women. Group 2: ongoing pregnancy rate in fresh cycle is 39.6%, the current cumulative ongoing pregnancy rate per patient was 45.6%. We observed a case of early onset OHSS. DISCUSSION AND CONCLUSION Triggering with agonist and administering an injection of 1500 IU of HCG the day of the pick up appears to be effective in women at risk of OHSS. The exclusion of all OHSS is still not reached. The search for the best protocol and its indications should continue.

Abstract
STUDY QUESTION Is severe early ovarian hyperstimulation syndrome (OHSS) completely prevented with the GnRH agonist trigger and 1500 IU hCG luteal rescue protocol? SUMMARY ANSWER Severe early OHSS can occur even after the GnRH agonist trigger and 1500 IU hCG luteal rescue protocol. WHAT IS KNOWN ALREADY Prior studies including over 200 women who received the GnRH agonist trigger and 1500 hCG luteal rescue protocol have reported complete prevention of severe early OHSS. Only a few late OHSS cases have been reported and it has been suggested that this protocol can be safely applied to any women under risk. STUDY DESIGN, SIZE, DURATION This retrospective cohort study included all women who were at high risk of OHSS and were given the GnRH agonist trigger plus hCG luteal rescue protocol between December 2008 and August 2012 in the two participating centers. PARTICIPANTS/MATERIALS, SETTING, METHODS There were 23 women with a mean estradiol level of 4891 ± 2214 pg/ml and a mean number of >12 mm follicles of 20 ± 6 on the day of ovulation triggering. OHSS was categorized according to the Golan criteria. MAIN RESULTS AND THE ROLE OF CHANCE Overall 6 of the 23 (26%) women developed severe OHSS. Five women had severe early OHSS requiring ascites drainage and hospitalization and three of these women did not undergo embryo transfer. The number of follicles measuring 10-14 mm on the day of triggering was significantly different between women who developed severe early OHSS and those who did not. LIMITATIONS, REASONS FOR CAUTION The small number of women with severe early OHSS may have prevented identification of other significant risk factors. WIDER IMPLICATIONS OF THE FINDINGS Although the GnRH agonist plus 1500 IU hCG luteal rescue protocol significantly decreases the risk of severe OHSS, this life threatening complication can still occur in high-risk patients. It would be prudent to avoid hCG luteal rescue and freeze all embryos for future transfer in such women particularly when there are ≥18 follicles with 10-14 mm diameters even with few larger follicles.

Abstract
PURPOSE Embryo cryopreservation after triggering oocyte maturation with GnRH agonist (GnRHa) in GnRH antagonist protocols has been proposed to prevent ovarian hyperstimulation syndrome (OHSS). However, a small percentage of patients still developed severe OHSS. The purpose of the study was to investigate the efficacy of preventing OHSS in patients at very high risk when cabergoline was given in addition to elective cryopreservation after GnRHa triggering. METHODS This is a retrospective observational study. The patients were stimulated with GnRH antagonist protocol. When serum E2 concentration was >6,000 pg/ml and there were more than 20 follicles ≥11 mm on the day of final oocyte maturation, GnRHa was used to trigger oocyte maturation. Cabergoline was given to augment the effect of preventing OHSS. The embryos were electively cryopreserved by vitrification and thawed in subsequent cycles. The primary outcome measure was the incidence of severe OHSS. The secondary outcome measure was the clinical pregnancy rate in the first frozen-thawed embryo transfer cycle. RESULTS One hundred and ten patients underwent 110 stimulated cycles were included for analysis. No patients developed moderate/severe OHSS. Mean E2 concentration on the day of final oocyte maturation was 7,873 pg/ml, and an average of 22.7 oocytes was obtained from each patient. One hundred and ten thawing cycles were performed, resulting in 69 clinical pregnancies (62.7 %). CONCLUSIONS Combining cabergoline and embryo cryopreservation after GnRHa triggering in GnRH antagonist protocol could prevent OHSS in patients at very high risk.

Abstract
The concept that a bolus of gonadotrophin-releasing hormone agonist (GnRHa) can replace human chorionic gonadotrophin(HCG) as a trigger of final oocyte maturation was introduced several years ago. Recent developments in the area strengthen this premise. GnRHa trigger offers important advantages, including virtually complete prevention of ovarian hyperstimulation syndrome(OHSS), the introduction of a surge of FSH in addition to the LH surge and finally the possibility to individualize luteal-phase supplementation based on ovarian response to stimulation. We maintain that the automatic HCG triggering concept should be challenged and that the GnRHa trigger is the way to move forward with thoughtful consideration of the needs, safety and comfort of our patients.
