Abstract
RESEARCH QUESTION Does splitting the human chorionic gonadotrophin (HCG) support in IVF cycles triggered by a gonadotrophin-releasing hormone agonist result in a better progesterone profile? DESIGN Randomized controlled three-arm study, performed at the Fertility Clinic, Odense University Hospital, Denmark. Patients with 12-25 follicles ≥12 mm were randomized into three groups: Group 1 - ovulation triggered with 6500 IU HCG; Group 2 - ovulation triggered with 0.5 mg GnRH agonist, followed by 1500 IU HCG on the day of oocyte retrieval (OCR); and Group 3 - ovulation triggered with 0.5 mg GnRH agonist, followed by 1000 IU HCG on the day of OCR and 500 IU HCG on OCR + 5. All groups received 180 mg vaginal progesterone. Progesterone concentrations were analysed in eight blood samples from each patient. RESULTS Sixty-nine patients completed the study. Baseline and laboratory data were comparable. Progesterone concentration peaked on OCR + 4 in Groups 1 and 2, and peaked on OCR + 6 in Group 3. On OCR + 6, the progesterone concentration in Group 2 was significantly lower compared with Groups 1 and 3 (P = 0.003 and P < 0.001, respectively). On OCR + 8, the progesterone concentration in Group 3 was significantly higher compared with the other groups (both P<0.001). Progesterone concentrations were significantly higher in Group 3 from OCR + 6 until OCR + 14 compared with the other groups (all P ≤ 0.003). Four patients developed ovarian hyperstimulation syndrome in Group 3. CONCLUSION Sequential HCG support after a GnRH agonist trigger provides a better progesterone concentration in the luteal phase.

Abstract
In recent years, there has been growing interest in understanding the dynamics of progesterone levels during the luteal phase after HCG-triggered ovulation. Recent studies have provided data showing a deviation from the natural ovulatory cycle, with peak progesterone concentrations occurring earlier and declining steadily thereafter, demonstrating that a fall in progesterone concentration early in the luteal phase was associated with lower rates of ongoing pregnancy. These findings highlight the importance of changes in progesterone concentration, rather than absolute concentrations, in determining optimal endometrial conditions. The disadvantages of HCG triggering, including the lack of a natural FSH surge and asynchronization between embryo age and endometrium receptivity, can be addressed by using gonadotrophin-releasing hormone agonist (GnRHa) triggering. GnRHa triggering induces both LH and FSH surges, ensures appropriate progesterone concentrations and offers flexibility in manipulating the luteal phase. Transitioning to GnRHa triggering could improve infertility treatment.

Abstract
BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is reduced when using antagonist cycle with gonadotrophin releasing hormone (GnRH) agonist trigger before ovum pick up. This trigger induces short luteinizing hormone (LH) and follicle stimulating hormone (FSH) peaks, resulting in an inadequate luteal phase and a reduced implantation rate. We assessed whether the luteal phase can be rescued by supplementing with oral dydrogesterone (duphaston) in antagonist cycles after a lone GnRH agonist trigger. METHODS A retrospective cohort study. The study group (N.=123) included women who underwent IVF. Patients received a GnRH-antagonist with a lone GnRH-agonist trigger due to imminent OHSS. The control group (N.=374) included patients who underwent a standard antagonist protocol with a dual trigger of a GnRH-agonist and human chorionic gonadotrophin (hCG). All the patients were treated with micronized progesterone (utrogestan) for luteal phase support. Study patients were given duphaston in addition. RESULTS The fertilization rate was comparable between the two groups. The mean number of embryos transferred, the clinical pregnancy rate and the take-home baby rate were comparable between groups (1.5±0.6 vs. 1.5±0.5 and 46.3% vs. 41.2%, and 66.7% vs. 87.7%, respectively). No OHSS event was reported in either group. CONCLUSIONS This study was the first to evaluate outcomes of duphaston supplementation for luteal support in an antagonist cycle with lone GnRH agonist trigger. The functionality of the luteal phase of those cycles could be restored by adding duphaston. This approach was found to be safe and prevented the need to postpone embryo transfer in case of pending OHSS.

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.

Low Luteal Serum Progesterone Levels Are Associated With Lower Ongoing Pregnancy and Live Birth Rates in ART: Systematic Review and Meta-Analyses. Front Endocrinol (Lausanne) 2022; 13:892753.

Abstract
UNLABELLED Progesterone plays a key role in implantation. Several studies reported that lower luteal progesterone levels might be related to decreased chances of pregnancy. This systematic review was conducted using appropriate key words, on MEDLINE, EMBASE, and the Cochrane Library, from 1990 up to March 2021 to assess if luteal serum progesterone levels are associated with ongoing pregnancy (OP) and live birth (LB) rates (primary outcomes) and miscarriage rate (secondary outcome), according to the number of corpora lutea (CLs). Overall 2,632 non-duplicate records were identified, of which 32 relevant studies were available for quantitative analysis. In artificial cycles with no CL, OP and LB rates were significantly decreased when the luteal progesterone level falls below a certain threshold (risk ratio [RR] 0.72; 95% confidence interval [CI] 0.62-0.84 and 0.73; 95% CI 0.59-0.90, respectively), while the miscarriage rate was increased (RR 1.48; 95% CI 1.17-1.86). In stimulated cycles with several CLs, the mean luteal progesterone level in the no OP and no LB groups was significantly lower than in the OP and LB groups [difference in means 68.8 (95% CI 45.6-92.0) and 272.4 (95% CI 10.8-533.9), ng/ml, respectively]. Monitoring luteal serum progesterone levels could help in individualizing progesterone administration to enhance OP and LB rates, especially in cycles without corpus luteum.

Abstract
It has been shown that in controlled ovarian hyper stimulation cycles, defective
luteal phase is common. There are many protocols for improving pregnancy
outcomes in women undergoing fresh and frozen in vitro fertilization cycles.
These approaches include progesterone supplements, human chorionic gonadotropin,
estradiol, gonadotropin-releasing hormone agonist, and recombinant luteinizing
hormone. The main challenge is luteal-phase support (LPS) in cycles with
gonadotropin-releasing hormone agonist triggering. There is still controversy
about the optimal component and time for starting LPS in assisted reproductive
technology cycles. This review aims to summarize the various protocols suggested
for LPS in in vitro fertilization cycles.

Abstract
Two modes of ovulation trigger are used in IVF: hCG, acting on ovarian LH receptors, and GnRH agonist, eliciting pituitary LH and FSH surges. These two modes are evaluated herein, focusing on how they serve specific time-sensitive events crucial for achieving embryo implantation and pregnancy. hCG trigger is associated with significant timing deviation from physiology. Peak progesterone is not synchronized with implantation window; progesterone level does not rise continuously to a mid-luteal peak, but rather drops from a too early peak. The luteal phase endocrinology post GnRH agonist trigger is characterized by a quick and irreversible luteolysis. Therefore, freeze all strategy is advised, if there is a risk of ovarian hyperstimulation syndrome. If fresh transfer is desired, numerous approaches for luteal phase support have been suggested. However, a thorough understanding of time-sensitive events suggests that a single 1,500 IU hCG dose, administered 48 h post oocyte retrieval, is all that is needed to fully support the luteal phase and secure best chances of achieving pregnancy.

Abstract
PURPOSE OF REVIEW In a conventional IVF cycle, final oocyte maturation and ovulation is triggered with a bolus of hCG, followed by progesterone-based luteal support that spans several weeks if pregnancy is achieved. This article summarizes several approaches of the exogenous progesterone-free luteal support in IVF. RECENT FINDINGS Triggering ovulation with GnRH agonist may serve as an alternative to hCG, with well established advantages. In addition, the luteal phase can be individualized in order to achieve a more physiologic hormonal milieu, and a more patient friendly treatment, alleviating the burden of a lengthy exogenous progesterone therapy. SUMMARY GnRH agonist trigger followed by a 'freeze all' policy is undoubtedly the best approach towards the 'OHSS-free clinic'. If fresh embryo transfer is considered well tolerated after GnRH agonist trigger, rescue of the corpora lutea by LH activity supplementation is mandatory. Herein we discuss the different approaches of corpus luteum rescue.

Abstract
STUDY QUESTION Does the freeze-all strategy in high-responders increase pregnancy rates and improve safety outcomes when compared with GnRH agonist triggering followed by low-dose hCG intensified luteal support with a fresh embryo transfer? SUMMARY ANSWER Pregnancy rates after either fresh embryo transfer with intensified luteal phase support using low-dose hCG or the freeze-all strategy did not vary significantly; however, moderate-to-severe ovarian hyperstimulation syndrome (OHSS) occurred more frequently in the women who attempted a fresh embryo transfer. WHAT IS KNOWN ALREADY Two strategies following GnRH agonist triggering (the freeze-all approach and a fresh embryo transfer attempt using a low-dose of hCG for intensified luteal phase support) are safer alternatives when compared with conventional hCG triggering with similar pregnancy outcomes. However, these two strategies have never been compared head-to-head in an unrestricted predicted hyper-responder population. STUDY DESIGN, SIZE, DURATION This study included women with an excessive response to ovarian stimulation (≥18 follicles measuring ≥11 mm) undergoing IVF/ICSI in a GnRH antagonist suppressed cycle between 2014 and 2017. Our primary outcome was clinical pregnancy at 7 weeks after the first embryo transfer. Secondary outcomes included live birth and the development of moderate-to-severe OHSS. PARTICIPANTS/MATERIALS, SETTING, METHODS Following GnRH agonist triggering, women were randomized either to cryopreserve all good-quality embryos followed by a frozen embryo transfer in an subsequent artificial cycle or to perform a fresh embryo transfer with intensified luteal phase support (1500 IU hCG on the day of oocyte retrieval, plus oral estradiol 2 mg two times a day, plus 200 mg of micronized vaginal progesterone three times a day). MAIN RESULTS AND THE ROLE OF CHANCE A total of 212 patients (106 in each arm) were recruited in the study, with three patients (one in the fresh embryo transfer group and two in the freeze-all group) later withdrawing their consent to participate in the study. One patient in the freeze-all group became pregnant naturally (clinical pregnancy diagnosed 38 days after randomization) prior to the first frozen embryo transfer. The study arms did not vary significantly in terms of the number of oocytes retrieved and embryos produced/transferred. The intention to treat clinical pregnancy and live birth rates (with the latter excluding four cases lost to follow-up: one in the fresh transfer and three in the freeze-all arms, respectively) after the first embryo transfer did not vary significantly among the fresh embryo transfer and freeze-all study arms: 51/105 (48.6%) versus 57/104 (54.8%) and 41/104 (39.4%) versus 42/101 (41.6%), respectively (relative risk for clinical pregnancy 1.13, 95% CI 0.87-1.47; P = 0.41). However, moderate-to-severe OHSS occurred solely in the group that received low-dose hCG (9/105, 8.6%, 95% CI 3.2% to 13.9% vs 0/104, 95% CI 0 to 3.7, P < 0.01). LIMITATIONS, REASONS FOR CAUTION The sample size calculation was based on a 19% absolute difference in terms of clinical pregnancy rates, therefore smaller differences, as observed in the trial, cannot be reliably excluded as non-significant. WIDER IMPLICATIONS OF THE FINDINGS This study offers the first comparative analysis of two common strategies applied to women performing IVF/ICSI with a high risk to develop OHSS. While pregnancy rates did not vary significantly, a fresh embryo transfer with intensified luteal phase support may still not avoid the risk of moderate-to-severe OHSS and serious consideration should be made before recommending it as a routine first-line treatment. Future trials may allow us to confirm these findings. STUDY FUNDING/COMPETING INTEREST(S) The authors have no conflicts of interest to disclose. No external funding was obtained for this study. TRIAL REGISTRATION NUMBER ClinicalTrials.gov identifier NCT02148393. TRIAL REGISTRATION DATE 28 May 2014. DATE OF FIRST PATIENT’S ENROLMENT 30 May 2014.

Abstract
This observational study included 21 patients at remarkably high risk of ovarian hyperstimulation syndrome (OHSS), characterized by more than 30 follicles measuring ≥11 mm in diameter on trigger day and/or pre-trigger peak estradiol exceeding 10 000 pg/mL, which was also the feature of women with established severe early OHSS followed by gonadotrophin-releasing hormone agonist (GnRHa) trigger and freeze-all policy that previously have been reported. All patients received a second dose of GnRHa 12 h after the first GnRHa trigger combined with administration of GnRH antagonist at 0.25 mg/day for a period of 3 days from the day of oocyte retrieval onwards. The in vitro fertilization (IVF) outcomes may be preferable compared with a bolus of GnRHa trigger and none of the included patients developed moderate-to-severe OHSS. Moreover, patients' symptoms, reproductive hormone levels and ultrasound findings were improved significantly. This new strategy seems to be efficacious and could be a further supplement of GnRHa trigger with or without applying freeze-all strategy to completely prevent early-onset moderate to severe OHSS, especially for the patients characterized by ≤30 follicles measuring ≥11 mm in diameter on trigger day and/or pre-trigger peak estradiol exceeding 10 000 pg/mL. Further studies should be performed to compare this regimen with conventional methods of OHSS prevention.

Abstract
In the past years, individualization of assisted reproductive technique (ART)-treatment is increasingly common to customize the treatment protocol to the patient's specific conditions. The use of GnRH-agonist for final oocyte maturation in a gonadotropin-releasing hormone (GnRH)-antagonist protocol is the best approach to reduce the risk for ovarian hyperstimulation in high responder patients. However, due to severe luteolysis, the reproductive outcome with this approach in combination with the use of vaginal progesterone as luteal phase support, was poor. Cycle segmentation as alternative to a fresh transfer requires embryo freezing which might not be applicable to all patients due to various reasons. The concept of luteal coasting monitors the progesterone-level closely and human chorionic gonadotropin (hCG) for rescue of the corpora lutea is administered when the progesterone-level drops below a certain threshold. However, the lower range of progesterone levels in the early luteal phase after GnRH-agonist trigger, which is compatible with achieving and maintaining a pregnancy, is unknown. This case-series demonstrates, that ongoing pregnancies can be achieved even with a progesterone-level below 15 ng/ml in the early luteal phase with the timely administration of an hCG-rescue bolus. With the concept of luteal coasting, individualization of the luteal phase support according to the patient's specific luteolysis pattern is possible.

Abstract
Small dose of hCG (1500 IU) on the day of oocyte retrieval, followed by daily progesterone administration, is currently the preferred way to secure adequate luteal support following GnRH agonist trigger. In the current proof-of-concept study, we explored the possibility that a bolus of 1500 IU hCG, given two days after oocyte retrieval, may be sufficient to sustain adequate luteal support without additional progesterone treatment. From February 2015 to August 2016, we obtained 44 pregnancies following GnRHa trigger followed by day 2 hCG (1500 IU) support only (study group). Data from these 44 cycles were compared with the latest 44 pregnancies obtained following hCG (6500 IU) trigger followed by conventional progesterone luteal documented (control group). Mean progesterone levels (14 days postoocyte retrieval) in the study and control groups were 197 nmol/l and 173 nmol/l, respectively (NS). Mean E2 levels (14 days post oocyte retrieval) in the study group was 6937 pmol/l, significantly higher (p < .001) than in the control group (3.276 pmol/l). We conclude that bolus of 1500 IU hCG, administered 2 days after retrieval, can provide excellent support, without the need to further supplement with progesterone.

Abstract
Ovarian stimulation in a gonadotropin-releasing hormone (GnRH) antagonist protocol with the use of GnRH agonist for final oocyte maturation is the state-of-the-art treatment in patients with an expected or known high response to avoid or at least reduce significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Due to a shortened LH surge after administration of GnRH agonist in most patients, the luteal phase will be characterized by luteolysis and luteal phase insufficiency. Maintaining a sufficient luteal phase is crucial for achievement of a pregnancy; however, the optimal approach is still under debate. Administration of human chorionic gonadotropin (hCG) within 72 h rescues the corpora lutea function; however, the so far often used 1,500 IU still bear the risk for development of OHSS. The recently introduced concept of "luteal coasting" individualizes the luteal phase support by monitoring the progesterone concentrations and administering a rescue dosage of hCG when progesterone concentrations drop significantly. This retrospective proof-of-concept study explored the correlation between hCG dosages ranging from 375 up to 1,500 IU and the progesterone levels in the early and mid-luteal phases as well as the likelihood of pregnancy, both early and ongoing. The chance of pregnancy is highest with progesterone level ≥13 ng/ml at 48 h postoocyte retrieval. Among the small sample size of 52 women studied, it appears that appropriate progesterone levels can be achieved with hCG dosages as low as 375 IU. This may well optimize the chance of pregnancy while reducing the risk of OHSS associated with higher doses of hCG supplementation in the luteal phase.

Abstract
The use of GnRH agonist to trigger final oocyte maturation in GnRH-antagonist in vitro fertilization (IVF) cycles has been shown to significantly reduce or even eliminate the risk of ovarian hyperstimulation syndrome (OHSS) by inducing rapid luteolysis early in the luteal phase. The exact mechanism of this early luteolysis is still widely unknown. Since luteinizing hormone (LH) has a major role in corpus luteum support, we sought to explore the pattern of LH secretion early in the luteal phase. Ten high risk patients for developing OHSS and triggered with GnRH agonist were included. Frequent blood sampling (every 20 min for 6 h) to measure LH, estradiol and progesterone was done on the day of oocyte collection (n = 5, Group 1) and on the day of embryo transfer, 48 h after oocyte collection (n = 5, Group 2). We found that the mean LH concentration and its secretion rate decreased significantly in Group 2 compared to Group 1. Both groups had similar number of LH pulses characterized by very small amplitude. In Group 2, there was a steady significant decrease in estradiol and progesterone over time. The results of this study show that LH secretion deviates significantly from normal physiologic pattern, which can explain, at least in part, the post-GnRH-agonist trigger early luteolysis mechanism.

Abstract
Final oocyte maturation using GnRH-agonist trigger in a GnRH-antagonist protocol is increasingly common, as ovarian hyperstimulation syndrome is almost completely avoided. However, this approach might lead to reduced pregnancy rates due to severe luteolysis. This proof of concept study evaluated the extend of luteolysis by measuring progesterone levels 48 hours after oocyte retrieval in 51 patients, who received GnRH-agonist trigger for final oocyte maturation in a GnRH-antagonist protocol due to the risk of ovarian hyperstimulation syndrome. It was shown, that luteolysis after GnRHa-trigger differs greatly among patients, with progesterone levels ranging from 13.0 ng/ml to ≥ 60.0 ng/ml, 48 hours after oocyte retrieval. Significant positive correlations could be demonstrated between progesterone levels and the number of ovarian stimulation and suppression days (p = 0.006 and p = 0.002 respectively), the total amount of medication used for ovarian suppression (p = 0.015), the level of progesterone on the day of final oocyte maturation (p = 0.008) and the number of retrieved oocytes (p = 0.019). Therefore it was concluded, that luteolysis after GnRH-agonist trigger is patient-specific and also luteal phase support requires individualization. Longer stimulation duration as well as a higher level of progesterone on the day of final oocyte maturation and more retrieved oocytes will result in higher levels of progesterone 48 hours after oocyte retrieval.

Abstract
Final oocyte maturation is a crucial step in in vitro fertilization, traditionally achieved with a single bolus of human chorionic gonadotropin (hCG) given 36 hours before oocyte retrieval. This bolus exposes the patient to the risks of ovarian hyperstimulation syndrome (OHSS), particularly in the face of ovarian hyper-response to gonadotropins. Although multiple measures were developed to prevent OHSS, gonadotropin-releasing hormone (GnRH) agonist triggering is now globally recognized as the best approach to achieve this goal. The first report on the use of GnRH agonist as ovulation trigger in the context of OHSS prevention came from Rambam Health Care Campus, Haifa, Israel and appeared in 1988. This review details the events that culminated in worldwide acceptance of this measure and describes its benefit in the field of assisted reproductive technology.

Abstract
Over the past few years, the use of Gonadotropin-releasing-hormone (GnRH)-agonist for final oocyte maturation in GnRH-antagonist-protocols in stimulated IVF/ICSI cycles has gained worldwide acceptance, as this approach reduces significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Final oocyte maturation with GnRH-agonist leads to sever luteolysis, which cannot be counterbalanced using standard luteal phase support with purely progesterone (P4) application and therefore administration of hCG or high doses of P4 is considered to be essential to prevent/counteract luteolysis. However, lately publications indicate, that luteolysis is not always complete after GnRH-agonist for trigger. This case-series evaluates the degree of luteolysis in high-responder-patients, who received GnRH-agonist for final oocyte maturation. Assessment of estradiol (E2)- and P4-levels 48 h after oocyte-pick-up (OPU) procedure demonstrate clearly, that luteolysis after GnRH-agonist trigger is individual-specific, even in high-responder patients with the same number of oocytes. Hence, individualization of luteal phase support with the focus on avoiding unnecessary administration of hCG, bearing the risk for development of OHSS, a new concept of luteal coasting needs to be developed, based on severity of luteolysis following luteal coasting.

Abstract
INTRODUCTION The use of GnRH agonist (GnRHa) for final oocyte maturation trigger in oocyte donation and elective frozen embryo transfer cycles is well established due to lower ovarian hyperstimulation syndrome (OHSS) rates as compared to hCG trigger. A recent Cochrane meta-analysis concluded that GnRHa trigger was associated with reduced live birth rates (LBRs) in fresh autologous IVF cycles compared to hCG trigger. However, the evidence is not unequivocal, and recent trials have found encouraging reproductive outcomes among couples undergoing GnRHa trigger and individualized luteal LH activity support. Thus, the aim was to compare GnRHa trigger followed by luteal LH activity support with hCG trigger in IVF patients undergoing fresh embryo transfer. MATERIAL AND METHODS We conducted a systematic review and meta-analysis of randomized trials published until December 14, 2016. The population was infertile patients submitted to IVF/ICSI cycles with GnRH antagonist cotreatment who underwent fresh embryo transfer. The intervention was GnRHa trigger followed by LH activity luteal phase support (LPS). The comparator was hCG trigger followed by a standard LPS. The critical outcome measures were LBR and OHSS rate. The secondary outcome measures were number of oocytes retrieved, clinical and ongoing pregnancy rates, and miscarriage rates. RESULTS A total of five studies met the selection criteria comprising a total of 859 patients. The LBR was not significantly different between the GnRHa and hCG trigger groups (OR 0.84, 95% CI 0.62, 1.14). OHSS was reported in a total of 4/413 cases in the GnRHa group compared to 7/413 in the hCG group (OR 0.48, 95% CI 0.15, 1.60). We observed a slight, but non-significant increase in miscarriage rate in the GnRHa triggered group compared to the hCG group (OR 1.85; 95% CI 0.97, 3.54). CONCLUSION GnRHa trigger with LH activity LPS resulted in comparable LBRs compared to hCG trigger. The most recent trials reported LBRs close to unity indicating that individualization of the LH activity LPS improved the luteal phase deficiency reported in the first GnRHa trigger studies. However, LPS optimization is needed to further limit OHSS in the subgroup of normoresponder patients (<14 follicles ≥ 11 mm). PROSPERO REGISTRATION NUMBER CRD42016051091.

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.
