Progesterone-primed cycles result in slower embryos without compromising implantation potential and with the advantages of oral administration and potential cost reduction. F&S SCIENCE 2024; 5:43-49. [PMID: 38061461 DOI: 10.1016/j.xfss.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 12/01/2023] [Accepted: 12/01/2023] [Indexed: 02/16/2024]
Abstract
OBJECTIVE To study the impact of the use of progesterone on embryo morphokinetics and on the outcomes of intracytoplasmic sperm injection cycles. DESIGN Cohort study. SETTING Private university-affiliated in vitro fertilization center. PATIENT(S) This study included 236 freeze-all intracytoplasmic sperm injection cycles and the resultant 2,768 injected oocytes cultured in a time-lapse imaging incubation system. Patients were matched by age and divided into groups depending on the protocol used to prevent the luteinizing hormone surge: progestin-primed (144 cycles and 1,360 embryos) and gonadotropin hormone-releasing hormone (GnRH) antagonist (144 cycles and 1,408 embryos) groups. INTERVENTION(S) The kinetic recorded markers were time to pronuclear appearance and fading, time to 2-8 cells, time to morulation, time to start of blastulation, and time to blastulation. The durations of cell cycles and time to complete synchronous divisions were calculated. The Known Implantation Data Score ranking was recorded. Morphokinetics and clinical outcomes were compared between the groups. MAIN OUTCOME MEASURE(S) Embryo morphokinetics and clinical outcomes. RESULTS Slower time to pronuclear appearance, time to 2 cells, time to 7 cells, time to start of blastulation, and time to blastulation were observed in embryos derived from progestin-primed cycles than in those from the GnRH antagonist group. No significant differences were noted in any other morphokinetic milestone. Significantly higher cancellation and implantation rates were observed in the progestin-primed group. However, no significant differences were noted in the pregnancy and miscarriage rates. The expenses for treatment using premature GnRH antagonist and progestins were US$318.18 and US$11.05, respectively. CONCLUSIONS Exogenous progesterone replaces the GnRH antagonist for the prevention of premature luteinizing hormone surge, in freeze-all cycles, with the advantage of oral administration and potential cost reduction.

Wesevich VG, Seckin SI, Kelk DA, Kallen AN, Kodaman PH. hMG addition affects the change in progesterone level during IVF stimulation and LBR: a retrospective cohort study. Reprod Biol Endocrinol 2023; 21:117. [PMID: 38057813 PMCID: PMC10699021 DOI: 10.1186/s12958-023-01150-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 10/12/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Premature progesterone (P) rise during IVF stimulation reduces endometrial receptivity and is associated with lower pregnancy rates following embryo transfer (ET), which can influence provider recommendation for fresh or frozen ET. This study aimed to determine whether change in P level between in IVF baseline and trigger (𝚫P) is predictive of pregnancy outcome following fresh ET, and whether the ratio of gonadotropins influences P rise and, as a result, clinical pregnancy outcomes: clinical pregnancy rate (CPR) and live birth rates (LBR). METHODS Retrospective cohort study at a single fertility center at an academic institution. The peak P level and 𝚫P were modeled in relation to prediction of CPR and LBR, and the ratios of hMG:rFSH were also modeled in relation to prediction of peak P level on day of trigger, 𝚫P, and CPR/LBR in a total of 291 patients undergoing fresh embryo transfer after controlled ovarian hyperstimulation-IVF (COH-IVF). RESULTS 𝚫P correlates with CPR, with the most predictive range for success as 𝚫P 0.7-0.85 ng/mL (p = 0.005, 95% CI 0.635, 3.636; predicting CPR of 88.9%). The optimal range for peak P in regard to pregnancy outcome was 0.15-1.349 ng/mL (p = 0.01; 95% CI for coefficient in model 0.48-3.570). A multivariable logistic model for prediction of CPR and LBR using either peak or 𝚫P supported a stronger association between 𝚫P and CPR/LBR as compared to peak P. Furthermore, an hMG:rFSH ratio of > 0.6 was predictive of lowest peak P (p = 0.010, 95% CI 0.035, 0.256) and smallest 𝚫P (p = 0.012, 95% CI 0.030, 0.243) during COH-IVF cycles. Highest CPRs were observed within hMG:rFSH ratios of 0.3-0.4 [75.6% vs. 62.5% within and outside of the range, respectively, (p = 0.023, 95% CI 0.119, 1.618)]. Highest LBRs were seen within the range of 0.3-0.6 hMG:rFSH, [LBR of 55.4% vs. 41.4% (p = 0.010, 95% CI 0.176, 1.311)]. CONCLUSIONS Our data supports use of 𝚫P to best predict pregnancy rates and therefore can improve clinical decision making as to when fresh ET is most appropriate. Furthermore, we found optimal gonadotropin ratios can be considered to minimize P rise and to optimize CPR/LBR, emphasizing the importance of luteinizing hormone (LH) activity in COH-IVF cycles.

Abstract
PURPOSE The aim of this narrative review is to offer an overview about the role of progesterone levels on pregnancy outcome in patients undergoing assisted reproductive technologies (ARTs). METHODS A detailed computerized search of the literature was performed in the main electronic databases (MEDLINE, EMBASE, Web of Science) to determine the importance of elevated progesterone levels at different stages of the cycle for pregnancy rates in the in vitro fertilization (IVF) cycle. Our review also provides information on the differences between elevated progesterone levels and their interpretation in normal and in poorly responding women. RESULTS After careful evaluation, our search strategy yielded a total of 15 included articles, showing the possible factors that may have had an impact on the increased progesterone level before human chorionic gonadotropin (HCG) injection and the different thresholds above which the pregnancy rate was lower. Furthermore, increased progesterone on cycle day 2 or 3 could serve as a marker for increased progesterone in the late follicular phase, which is associated with a lower pregnancy rate. CONCLUSION Despite the literature data that support the negative effect of elevated progesterone on fresh cycles, due to lack of randomized controlled trials, the value of measuring progesterone in daily practice is questionable. Available evidence supports the detrimental effect of elevated progesterone in different subgroups of women, although there is still the need for defining different thresholds and durations of high progesterone exposure. The need for various thresholds for different cohorts of women, the inter-assay variability is making this decision harder.

Abstract
BACKGROUND Obesity has now been recognized as a high-risk factor for reproductive health. Although remarkable advancements have been made in ART, a considerable number of infertile obese women still suffer from serial implantation failure, despite the high quality of embryos transferred. Although obesity has long been known to exert various deleterious effects on female fertility, the underlying mechanisms, especially the roles of lipid metabolism in endometrial receptivity, remain largely elusive. OBJECTIVE AND RATIONALE This review summarizes current evidence on the impacts of several major lipids and lipid-derived mediators on the embryonic implantation process. Emerging methods for evaluating endometrial receptivity, for example transcriptomic and lipidomic analysis, are also discussed. SEARCH METHODS The PubMed and Embase databases were searched using the following keywords: (lipid or fatty acid or prostaglandin or phospholipid or sphingolipid or endocannabinoid or lysophosphatidic acid or cholesterol or progesterone or estrogen or transcriptomic or lipidomic or obesity or dyslipidemia or polycystic ovary syndrome) AND (endometrial receptivity or uterine receptivity or embryo implantation or assisted reproductive technology or in vitro fertilization or embryo transfer). A comprehensive literature search was performed on the roles of lipid-related metabolic pathways in embryo implantation published between January 1970 and March 2022. Only studies with original data and reviews published in English were included in this review. Additional information was obtained from references cited in the articles resulting from the literature search. OUTCOMES Recent studies have shown that a fatty acids-related pro-inflammatory response in the embryo-endometrium boundary facilitates pregnancy via mediation of prostaglandin signaling. Phospholipid-derived mediators, for example endocannabinoids, lysophosphatidic acid and sphingosine-1-phosphate, are associated with endometrial receptivity, embryo spacing and decidualization based on evidence from both animal and human studies. Progesterone and estrogen are two cholesterol-derived steroid hormones that synergistically mediate the structural and functional alterations in the uterus ready for blastocyst implantation. Variations in serum cholesterol profiles throughout the menstrual cycle imply a demand for steroidogenesis at the time of window of implantation (WOI). Since 2002, endometrial transcriptomic analysis has been serving as a diagnostic tool for WOI dating. Numerous genes that govern lipid homeostasis have been identified and, based on specific alterations of lipidomic signatures differentially expressed in WOI, lipidomic analysis of endometrial fluid provides a possibility for non-invasive diagnosis of lipids alterations during the WOI. WIDER IMPLICATIONS Given that lipid metabolic dysregulation potentially plays a role in infertility, a better understanding of lipid metabolism could have significant clinical implications for the diagnosis and treatment of female reproductive disorders.

Abstract
Ovarian stimulation is an indispensable part of IVF and is employed to produce multiple ovarian follicles. In women who undergo ovarian stimulation with gonadotropins, supraphysiological levels of estradiol, as well as a premature rise in progesterone levels, can be seen on the day of hCG administration. These alterations in hormone levels are associated with reduced embryo implantation and pregnancy rates in IVF cycles with a fresh embryo transfer. This article aims to improve the reader’s understanding of the effects of elevated progesterone levels on human endometrial receptivity and oocyte/embryo quality. Based on current clinical data, it appears that the premature rise in progesterone levels exerts minimal or no effects on oocyte/embryo quality, while advancing the histological development of the secretory endometrium and displacing the window of implantation. These clinical findings strongly suggest that reduced implantation and pregnancy rates are the result of a negatively affected endometrium rather than poor oocyte/embryo quality. Understanding the potential negative impact of elevated progesterone levels on the endometrium is crucial to improving implantation rates following a fresh embryo transfer. Clinical studies conducted over the past three decades, many of which have been reviewed here, have greatly advanced our knowledge in this important area.

Abstract
PURPOSE Some women undergoing stimulated cycles have elevated serum progesterone (P) on the day of ovulation trigger, but its effect on embryo quality is unclear. We analyze embryo quality among patients with high and low serum P undergoing preimplantation genetic testing for aneuploidy (PGT-A). METHODS This retrospective study included 1597 patients divided into two groups by serum P values: < 1.5 ng/mL or ≥ 1.5 ng/mL. A gonadotrophin-releasing hormone (GnRH) antagonist protocol was established for each patient. Serum P levels were measured on the day of triggering. Propensity score matching and Poisson regression were done. Age, body mass index, and ovarian sensitivity index were also compared. RESULTS Elevated serum P was not significantly associated with euploid embryo rate or other embryo-quality variables evaluated in our study. Age was the only variable associated with euploidy rate (per MII oocyte, P < 0.001; per biopsied embryo, P = 0.008), embryo biopsy rate (P < 0.001), absolute number of euploid embryos (P = 0.008), and top-quality embryo rate (P = 0.008). Categorical variables decreased in value for every year of increased age in patients with high serum P. CONCLUSIONS Elevated serum P did not affect the number of euploid and good-quality embryos for transfer in GnRH antagonist intracytoplasmic sperm injection (ICSI) cycles. Contrary to the clear influence of premature P elevation on endometrial receptivity based on literature, our results may help to tip the balance towards the absence of a negative effect of P elevation on embryo competence. More studies are needed to fully understand the effect of P elevation on reproductive outcomes.

Abstract
BACKGROUND Conflicting evidence still prevails concerning the effect of preovulatory elevated progesterone (EP4) on reproductive outcomes in fresh embryo transfer (ET). However, few studies have analyzed the effect of EP4 on the likelihood of pregnancy using multivariate regression approach. The potential confounding factors tested in these studies were limited to either patient's characteristics or to stimulation related parameters. Yet, several studies have shown that postovulatory parameters such as midluteal progesterone (P4) level may be considered as a proxy variable of endometrial receptivity as well. OBJECTIVE The aim of the present study was to estimate the independent effect of preovulatory P4 effect, if any, on the probability of live birth (LB) by considering the midluteal endocrine profile when controlling for the potential confounding factors. METHODS This is a secondary data analysis of a cohort of fresh IVF/ICSI cycles triggered with GnRH agonist (n = 328) performed in a single IVF center during the period 2014-2016. Patients contributed only one cycle and were stratified into four groups according to preovulatory P4 quartiles. We assessed the association between preovulatory P4 and the odds of LB calculated by logistic regression analysis after controlling for the most clinically relevant confounders. The primary outcome measure: Live birth rates (LBR). RESULTS Both preovulatory and midluteal P4 were significantly correlated with the ovarian response. Logistic regression analysis showed that preovulatory serum P4 did not have a significant impact on LBR. In contrast, midluteal serum P4 level was an important independent factor associated with LBR. The optimal chance of LBR was achieved with midluteal serum P4 levels of 41-60 ng/ml, [OR: 2.73 (1.29-5.78); p< 0.008]. CONCLUSION The multivariate analysis suggests that the midluteal P4 level seems to impact LBR more than the preovulatory P4 level in women undergoing IVF treatment followed by fresh ET.

Abstract
PURPOSE Premature luteinization (PL) affects 12.3-46.7% of fresh in vitro fertilization cycles, and there is accumulating evidence confirming its negative effect on success rates. However, despite its clinical significance, PL is poorly understood and defined. This narrative review aims to provide a fresh look at the phenomenon of PL by summarizing the existing evidence and re-evaluating fundamental issues. METHODS A thorough electronic search was conducted covering the period from 1978 until January 2018 in PubMed, Embase, and Medline databases, and references of relevant studies were cross-checked. Meeting proceedings of the European Society of Human Reproduction and Embryology and the American Society for Reproductive Medicine were also hand searched. RESULTS In the curious case of PL, one should go back to the beginning and re-consider every step of the way. The pathogenesis, definition, measurement methods, clinical implications, and management strategies are discussed in detail, highlighting controversies and offering "food for thought" for future directions. CONCLUSIONS Authors need to speak the same language when studying PL in order to facilitate comparisons. The terminology, progesterone cut-off, measurement methods and days of measurement should be standardized and globally accepted; otherwise, there can be no scientific dialog. Future research should focus on specific patient profiles that may require a tailored approach. Progesterone measurements throughout the follicular phase possibly depict the progesterone exposure better than an isolated measurement on the day of hCG. Adequately powered randomized controlled trials should confirm which the best prevention and management plan of PL is, before introducing any strategy into clinical practice.

Abstract
Premature progesterone (P) elevation was commonly seen in IVF prior to the utilization of GnRH analogues for suppression of endogenous gonadotropin release. The cause and effect of premature P elevation has finally been better elucidated in the past decade. Although still occurring in 5-38% of all IVF cycles, the adverse effects of premature P elevation on pregnancy outcomes are now well known.

Abstract
While an association can be addressed among endometriosis and subfertility, the causal relationship has not been elucidated yet. Impaired oocyte quality in endometriosis patients has been accused for the unsuccessful outcomes of assisted reproductive techniques. There are limited studies in literature evaluated association between endometriosis and oocyte morphology. We conducted this retrospective study to evaluate whether morphological abnormalities of oocytes are more common in women with endometriosis than women with diagnosis of male factor infertility as a source of healthy oocytes. Totally 1568 oocytes, 775 (49.4%) in endometriosis groups and 793 (50.6%) in control group were evaluated for morphological parameters before ICSI cycles. Abnormal oocyte morphology was detected in 352 (22.4%) of 1568 oocytes. Of the abnormal oocytes, 208 (59.1%) were in endometriosis group and 144 (40.9%) in control group (p < .001). The following dysmorphisms were significantly higher in oocytes retrieved from endometriosis group: dark cytoplasm; dark, large or thin zona pellucida; and flat or fragmented polar body (p < .05 for all). When morphological parameters for oocytes of endometriosis patients evaluated, the oocyte defects has increased significantly in endometriosis patients. These findings are thought to be useful to clarify the subfertility in endometriosis patient, which needs to be confirmed with further studies.

Efficacy of luteal estrogen administration and an early follicular Gonadotropin-releasing hormone antagonist priming protocol in poor responders undergoing in vitro fertilization. Obstet Gynecol Sci 2018; 61:102-110. [PMID: 29372156 PMCID: PMC5780304 DOI: 10.5468/ogs.2018.61.1.102] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2017] [Revised: 07/22/2017] [Accepted: 07/24/2017] [Indexed: 11/08/2022] Open
Abstract
Objectives We investigated whether luteal estrogen administration and an early follicular Gonadotropin-releasing hormone antagonist (E/G-ant) priming protocol improves clinical outcomes in poor responders to controlled ovarian stimulation for in vitro fertilization (IVF)-embryo transfer, and identified underlying mechanisms. Methods This restrospective study consisted of 65 poor responders who underwent the E/G-ant priming protocol. Sixty-four other poor responders undergoing conventional protocols without pretreatment were included as the control group. Clinical outcomes were compared between 2 groups. Results The E/G-ant priming protocol group exhibited improvements over the control group in terms of the number of retrieved oocytes (3.58±2.24 vs. 1.70±1.45; P=0.000), mature oocytes (2.68±2.11 vs. 1.65±1.23; P=0.000), fertilized oocytes (2.25±1.74 vs. 1.32±1.26; P=0.001), good embryos (1.62±0.91 vs. 1.14±0.90, P=0.021). Day 3 follicle-stimulating hormone (FSH; 8.40±4.84 vs. 16.39±13.56; P=0.000) and pre-ovulation progesterone levels (0.67 vs. 1.28 ng/mL; P=0.016) were significantly higher in the control group than in the E/G-ant priming group. The overall rate of positive human chorionic gonadotropin tests was higher in the E/G-ant priming group than in the control group (32.3% vs.16.1%; P=0.039). Also, clinical pregnancy rate (26.2% vs. 12.5%; P=0.048) and the rate of live births (23.1% vs. 7.1%; P=0.023) were significantly higher in the E/G-ant priming group than in the control group. Conclusion The E/G-ant priming protocol would lead to promising results in poor responders to IVF by suppressing endogenous FSH and by preventing premature luteinization.

Top quality blastocyst formation rates in relation to progesterone levels on the day of oocyte maturation in GnRH antagonist IVF/ICSI cycles. PLoS One 2017; 12:e0176482.

Abstract
Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a "freeze-all" strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity. However, also a detrimental effect of elevated progesterone on day-3 embryo quality has recently been found with regards to top quality embryo formation rate. Because blastocyst culture and cryopreservation are largely adopted, we deemed relevant to determine whether this detrimental effect is also seen on blastocyst quality on day 5-6. This issue was investigated through a large two-center retrospective study including 986 GnRH antagonist IVF/ICSI cycles and using top quality blastocyst formation rate as the main outcome. Results showed that on multivariate analysis sperm motility (p<0.01) and progesterone levels at ovulation triggering (p = 0.01) were the only two variables that significantly predicted top quality blastocyst formation rate after adjusting for relevant factors including female age, BMI, basal AMH and total dose of FSH used for COS. More specifically, progesterone levels at induction showed an inverse relation with top quality blastocyst formation (correlation coefficient B = -1.08, 95% CI -1.9 to -0.02) and ROC curve analysis identified P level >1.49 ng/ml as the best cut-off for identification of patients at risk for the absence of top quality blastocysts (AUC 0.55, p<0.01). Our study is the first to investigate the top quality blastocyst formation rate in relation to progesterone levels in IVF/ICSI cycles, showing that increasing progesterone is associated with lower rates of top quality blastocyst. Hence, the advantages of prolonging COS to maximize the number of collected oocytes might eventually be hindered by a decrease in top quality blastocysts available for transfer, if increasing progesterone levels are observed. This observation extends the results of two recent studies focused on day-3 embryos and deserves further research.

Effect of premature serum progesterone rise on embryo transfer outcomes and the role of blastocyst culture and transfer in assisted reproductive technology cycles with premature progesterone rise. Taiwan J Obstet Gynecol 2016; 54:641-6. [PMID: 26700978 DOI: 10.1016/j.tjog.2014.03.014] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/13/2014] [Indexed: 10/22/2022] Open
Abstract
OBJECTIVE In 1991, researchers reported that a modest preovulatory increase in serum progesterone levels is associated with lower pregnancy rates and higher incidence of pregnancy loss in in vitro fertilization (IVF). We wonder whether embryo transfer (ET) in assisted reproductive technology (ART) cycles in patients with premature progesterone rise (PPR) have a negative impact on the clinical pregnancy rates (CPRs) and/or live birth rates (LBRs) in our series. Consequently, will blastocyst transfer reverse the negative impact? MATERIALS AND METHODS This noninterventional, retrospective, observational tertiary center study was conducted between January 2010 and December 2012. All fresh ET cycles with serum progesterone levels measured (n = 599) on the day of hCG administration were analyzed. RESULTS Sera lutenizing hormone (LH), E2, and progesterone (P) were measured and analyzed. The CPRs of cycles in patients with p ≤ 1.5 ng/mL (low) versus those with p > 1.5 ng/mL (high) were 37.04% versus 41.03% [odds ratio (OR) = 1.18, 95% confidence interval (CI): 0.728-1.920; p = 0.50). The LBRs of cycles in patients with low progesterone level versus those with PPR were 30.52% versus 34.62% (OR = 1.21, 95% CI: 0.729-1.992; p = 0.47). No statistically significant association was detected. We further analyzed the outcomes according to different stages of ET and found that blastocyst (D5) ET significantly increase the LBRs as compared with cleavage stage (D2/D3) ET in the PPR group (44.44% versus 21.43%; p = 0.043). CONCLUSION PPR did not significantly compromise the clinical outcomes in this series. However, shifting to blastocyst transfer probably could increase the live birth in cycles with PPR.

Abstract
To demonstrate the incidence and effects of elevated progesterone (P) on the trigger day on the outcome of in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles using Medroxyprogesterone acetate (MPA) co-treated with Human Menotrophins Gonadotrophin (hMG + MPA), we performed a retrospective analysis including 4106 IVF/ICSI cycles. The cycles were grouped according to the P level on the trigger day: <1 ng/mL, between 1–1.5 ng/ml (including 1), between 1.5–2 ng/mL (including 1.5), and ≥2 ng/mL. The primary outcome measure was live birth rate. The prevalence of P level categories was 12.93% (531/4106), 2.92% (120/4106), and 1.92% (79/4106) in women with P between 1–1.5 ng/mL, between 1.5–2 ng/mL, and ≥2 ng/mL, respectively. The mean stimulation duration, total hMG dose, serum follicle stimulating hormone (FSH), estrogen(E2) on the trigger day and the number of oocytes in patients with elevated P were significantly higher than patients with P < 1 ng/mL (P < 0.05). However, there were no significant differences in the oocyte retrieval rates, fertilization rates, implantation rates, clinical pregnancy rates and live birth rates between the groups based on frozen embryo transfer (FET). We concluded that elevated P on the trigger day had no negative effect on the final outcome of the hMG + MPA treatment cycles based on FET.

Abstract
OBJECTIVE The aim of the presented study is to investigate the impact of progesterone change in the late follicular phase on the pregnancy rates of both agonist and antagonist protocols in normoresponders. STUDY DESIGN A total of 201 normoresponder patients, who underwent embryo transfer were consecutively selected. 118 patients were stimulated using a long luteal GnRH agonist protocol and 83 using a flexible antagonist protocol. The level of change in late follicular phase progesterone was calculated according to the progesterone levels on the hCG day and pre-hCG day (1 or 2 days prior to hCG day) measurement. RESULTS Clinical pregnancy rates were comparable between long luteal and antagonist group (35.6 and 41%, respectively). The incidence of progesterone elevation on the hCG day was 11% in long luteal and 18% in antagonist group (p = 0.16). In pregnant cycles, p levels both on the hCG day and pre-hCG day measurement were significantly higher in antagonist than agonist cycles (p = 0.029, p = 0.038, respectively). The change of p level was statistically significant in non-pregnant cycles both for the agonist (-0.17 ± 0.07; 95% CI: -0.29 to -0.37) and antagonist groups (-0.18 ± 0.07; 95%CI: -0.31 to -0.04). CONCLUSIONS Late follicular phase progesterone levels were stable during the cycles of pregnant patients irrespective of the protocols and were shown to be higher in pregnant patients in antagonist cycles when compared to agonist cycles.

Abstract
BACKGROUND: The effect of elevated levels of serum progesterone (P4) and estradiol (E2) on the day of human chorionic gonadotropin and their cut-off value on in vitro fertilization (IVF) outcomes is still not clear. AIMS: The aim was to evaluate the association between serum P4, E2 and progesterone/estradiol ratio (P4/E2) on pregnancy outcome in IVF/intracytoplasmic sperm injection (ICSI) cycles with long agonist protocol. SETTING AND DESIGN: Retrospective, single center, cohort study. MATERIALS AND METHODS: A review of complete data of 544 women undergoing fresh IVF/ICSI cycles (539 cycles) with long agonist protocol from January 2012 to February 2014 was done. Data were stratified into Three groups according to the number of oocytes retrieved: low (≤4 oocytes obtained), intermediate (5–19 oocytes obtained), and high ovarian response (≥20 oocytes obtained). STATISTICAL ANALYSIS: Fishers exact test/Chi-square was carried for comparing categorical data. Receiver operating characteristics analysis was performed to determine the cut-off value for P4 and P4/E2 detrimental for pregnancy. RESULTS: A negative association was observed between pregnancy rate (PR) and serum P4 and P4/E2 levels with no effect on fertilization and cleavage rate. The overall cut-off value of serum P4 and P4/E2 ratio detrimental for pregnancy was found to be 1.075 and ≥0.35, respectively. Different P4 threshold according to the ovarian responders were calculated, 1.075 for intermediate and 1.275 for high responders. Serum E2 levels were not found to be significantly associated with PR. CONCLUSION: Serum P4 levels and P4/E2 ratio are a significant predictor for pregnancy outcome without affecting cleavage and fertilization rate while serum estradiol levels do not seem to affect PR.

Abstract
OBJECTIVE To evaluate if an elevated progesterone (P) level on the day of human chorionic gonadotropin (hCG) administration is associated with a decrease in live-birth rate in patients with a good prognosis. DESIGN Retrospective cohort study. SETTING Large, private, assisted reproductive technology (ART) practice. PATIENT(S) One thousand six hundred twenty fresh autologous ART cycles. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Live-birth rate. RESULT(S) A total of 934 blastocyst and 686 cleavage-stage embryo transfer (ET) cycles were evaluated. Serum P levels were not associated with markers of oocyte or embryo quality, including fertilization, embryo stage at transfer, and embryos available for cryopreservation. Patient age, stage of ET, embryo quality, the number of embryos transferred, and P level on the day of hCG administration were all significantly associated with live birth. Higher P levels were associated with decreased odds of live birth for cleavage- and blastocyst-stage embryos, poor-fair and good-quality embryos, and poor- and high-responder patients. The nonsignificance of interaction tests of P levels with embryo stage, embryo quality, patient age, and ovarian response indicated that the relationship between P level and live birth was similar regardless of these factors. CONCLUSION(S) An elevated serum P level on the day of hCG administration was negatively associated with live birth, even in ETs with a good prognosis.

OBJECTIVES Clarifying whether the addition of recombinant LH (rLH) to recombinant FSH (rFSH) leads to progesterone (P4) levels on dhCG comparable to those obtained with stimulation with FSH and hCG (HP-hMG) MATERIALS AND METHODS: Pituitary-desensitized patients, matched for age and follicle reserve, received rFSH+LH (n=729) or HP-hMG (n=729). In the rFSH+rLH group, rLH (75 UI/day) was started at day 6. To control for the influence of ovarian response on P4, we divided serum P4 levels by the number of growing follicles (13-22 mm; "per follicle" P4 levels) and performed a multivariate analysis. RESULTS Serum P4 levels on dHCG were lower in the HP-hMG (median: 0.63 ng/mL, max-min: 0.10-2.97) than in the rFSH+rLH group (0.91 ng/mL; 0.10-4.65, P<0.0001), as well as "per-follicle" P4 levels (0.055 ng/mL/growing follicle, 0.006-0.284 vs 0.077 ng/mL/growing follicle, 0.003-0.336; P<0.0001). CONCLUSIONS HP-hMG led to lower P4 levels on day hCG than rFSH+rLH irrespective of the intensity of the ovarian response and the adjunction of rLH (75 IU/day from day 6 onward).

Abstract
PURPOSE Modest increases of serum progesterone at human chorionic gonadotrophin (hCG) administration in controlled ovarian hyperstimulation (COH) cycles have been shown to have a negative impact on pregnancy outcomes. The aim of this study was to identify early predictors of progesterone elevation at hCG. DESIGN Pregnancy outcome of 303 consecutive patients undergoing COH and fresh day-3 embryo transfer was analysed. Considering the non-linear relationship between progesterone at hCG triggering and pregnancy outcomes, partial area under the curve (pAUC) analysis was used to implement marker identification potential of receiver operating characteristic (ROC) curve analysis. Multivariate logistic analysis was then performed to identify predictors of progesterone rise. RESULTS Pregnancy outcomes could be predicted by pAUC analysis (pAUC = 0.58, 95 % CI 0.51-0.66, p = 0.02) and a significant detrimental cut-off could be calculated (progesterone at hCG > 1.35 ng/ml). Total dose of rFSH administered, E2 level at hCG but mostly basal progesterone level (OR = 12.21, 95 % CI 1.82-81.70) were predictors of progesterone rise above the cut-off. CONCLUSION Basal progesterone is shown to be the main prognostic factor for progesterone elevation. This observation should be taken into consideration in the clinical management of IVF/ICSI cycles to improve pregnancy outcomes.

Abstract
OBJECTIVE To investigate the relationship between serum P levels on the day of hCG administration and pregnancy outcomes in different responders undergoing IVF. DESIGN Retrospective study. SETTING Teaching hospital. PATIENT(S) A total of 11,055 women who underwent their first IVF/intracytoplasmic sperm injection cycles and a subgroup of 4,021 women undergoing frozen-embryo transfer (FET) cycles. INTERVENTION(S) Patients underwent IVF-ET with the long GnRH agonist protocol. The ovarian response was classified as high (≥ 20 oocytes; n = 2,023), poor (≤ 4 oocytes; n = 827), or intermediate (remaining cases; n = 8,205) according to the number of oocytes retrieved. Clinical outcomes of IVF-ET and FET cycles were analyzed according to plasma P levels. MAIN OUTCOME MEASURE(S) Ongoing pregnancy rates (PRs). RESULT(S) Ongoing PRs in fresh cycle were inversely associated with serum P levels on the day of hCG administration for all patients. Different P threshold concentrations were determined according to different ovarian response: We proposed a serum P level of 1.5 ng/mL as the threshold for poor responders, 1.75 ng/mL for intermediate responders, and 2.25 ng/mL for high responders. Our study does not show negative results for elevated P levels on oocyte performance in terms of fertilization, cleavage rate, or PR of FET cycles within different ovarian responses, offering no evidence for a detrimental effect of high P on oocyte quality. CONCLUSION(S) Elevated P levels on the day of hCG administration negatively influence PR regardless of different ovarian responses, although increased P threshold concentration is associated with better ovarian responses. The detrimental effect of P elevation on PR seems to be unrelated to oocyte quality in all responders.

Abstract
There is an ongoing debate regarding the impact of premature progesterone rise on the IVF outcome. The objective of this review is to assess evidence of poorer ongoing pregnancy rate in IVF cycles with elevated serum progesterone at the end of follicular phase in ovarian stimulation. It also explores the origin of the progesterone rise, potential modifying factors and possible methods to prevent its rise during ovarian stimulation. This review draws on information already published from monitoring progesterone concentrations at the end of follicular phase in ovarian stimulation. The databases of Medline and PubMed were searched to identify relevant publications. Good-quality evidence supports the negative impact on endometrial receptivity of elevated progesterone concentrations at the end of the follicular phase in ovarian stimulation. Future trials should document the cause and origin of premature progesterone in stimulated IVF cycles.

Abstract
Human chorionic gonadotrophin (HCG) may substitute FSH to complete follicular growth in IVF cycles. This may be useful in the prevention of ovarian hyperstimulation syndrome. Relevant studies were identified on Medline. To evaluate outcomes, a meta-analysis of low-dose HCG-supplemented IVF cycles versus non-supplemented ones was performed with data from 435 patients undergoing IVF who were administered low-dose HCG in various agonist and antagonist protocols and from 597 conservatively treated patients who served, as control subjects. Using these published data, a decision analysis evaluated four different management strategies. Effectiveness and economic outcomes were assessed by FSH consumption, clinical pregnancy and incremental cost-effectiveness ratios. Clinical pregnancy and ovarian hyperstimulation were the main outcome measures. Nine trials published in 2002-2007 were included. From the prospective studies, in the gonadotrophin-releasing hormone antagonist group, a trend for significance in clinical pregnancy rate was evident (odds ratio [OR], 1.54; 95% confidence interval [CI], 0.98-2.42). Ovarian hyperstimulation was less significant in the antagonist low-dose HCG protocol compared with the non-supplemented agonist protocol (OR 0.30; 95% CI 0.09-0.96). Less FSH was consumed in the low-dose HCG group but this difference was not statistically significant. Low-dose HCG supplementation may improve pregnancy rates in antagonist protocols. Overall, low-dose HCG-supplemented protocols are a cost-effective strategy.

Abstract
Premature luteinization (PL) refers to a rise in serum progesterone (P) levels on the day of hCG administration. Most studies used an absolute P level on the day of hCG administration as an indicator of PL, and the cutoff level differed from 0.8 to 2 ng/mL. Some authors defined PL as a P/E2 ratio of >1. There is a marked variation in the incidence (13% to 71%), of PL due to discrepancies in definition, population characteristics and/or treatment protocols. The pathogenesis of PL in COH is still poorly understood. Several hypotheses may be considered to explain this phenomenon: elevation of follicular LH levels, serum accumulation of HCG from HMG, increased LH receptor sensitivity of the granulosa cells to FSH, or poor ovarian response with increased LH sensitivity. The consequences of this premature elevation of serum P on IVF outcome remain controversial. Attempts to prevent COH include: use of Low-dose hCG alone in the late COH stages, flexible antagonist protocol, use of mifepristone, aspiration of a single leading follicle, hCG administration when the levels of serum P exceeded 1.0 ng/mL.

Abstract
OBJECTIVE To determine whether embryo cryopreservation in cycles with elevated preovulatory P followed by thaw, extended culture, and transfer results in greater ongoing pregnancy rates than fresh blastocyst transfer. DESIGN Retrospective matched cohort study. SETTING Private fertility center. PATIENT(S) The study group consisted of 118 consecutive thaws of bipronucleate (2PN) oocytes derived from autologous cycles with elevated preovulatory P, resulting in 95 blastocyst transfers. The control group was selected by matching on the number of 2PN oocytes and patient age and consisted of 118 fresh cycles with elevated preovulatory P, including 108 fresh autologous blastocyst transfers. All patients were <41 years old at the time of stimulation. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Implantation and ongoing pregnancy rates. RESULT(S) The study group had significantly fewer blastocysts per 2PN oocyte than the control group (19.7% vs. 36.8%, respectively) and a significantly greater cancellation rate (19.5% vs. 8.5%, respectively). However, the ongoing pregnancy rate per cycle was significantly higher in the study group than in the control group (56.8% vs. 32.2%, respectively), resulting from greater rates of implantation (56.8% vs. 26.9%, respectively) and of ongoing pregnancy per transfer (70.5% vs. 35.2%, respectively). CONCLUSION(S) In cycles with elevated preovulatory P, the probabilities of implantation and ongoing pregnancy are increased if all 2PN oocytes are cryopreserved and subsequently thawed and cultured to the blastocyst stage before transfer.

Abstract
OBJECTIVE To identify dominant predictors of clinical pregnancy in IVF cycles. DESIGN Retrospective study. SETTING Private fertility center. PATIENT(S) The study included 580 fresh autologous IVF cycles with blastocyst transfer. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Clinical pregnancy rate. RESULT(S) A set of 25 suspected predictors was used to develop predictive models of clinical pregnancy in a set of 361 blastocyst transfer cycles. Initial bivariate analysis identified 14 of these variables that were significant enough to be candidate variables for multiple logistic regression. Similar sets of significant variables were identified by using alternative approaches for model construction. The final model included blastocyst diameter, day of blastulation, and preovulatory serum P level as significant predictors of clinical pregnancy. Specifically, clinical pregnancy was predicted by preovulatory serum P of <1.0 ng/mL, blastulation on day 5, and large blastocyst diameter. Of these variables, blastocyst diameter was the most significant predictor of clinical pregnancy in the multivariate models. The final model was validated against a separate set of 219 subsequent blastocyst transfer cycles. CONCLUSION(S) Pre-ovulatory serum P level, blastulation day, and embryo diameter are simultaneously predictive of clinical pregnancy, and their relationships with clinical pregnancy are consistent with an effect of embryo-endometrium synchrony.

Abstract
The role of progesterone elevation on in vitro fertilization (IVF) outcome has remained a debatable issue for several years. The aim of this systematic review and meta-analysis was to evaluate whether progesterone elevation on the day of human chorionic gonadotrophin (hCG) administration is associated with the probability of pregnancy. Eligible studies were considered those in which patients did not participate more than once. A literature search in MEDLINE, EMBASE and CENTRAL identified 12 eligible studies, 10 of which were retrospective. The majority (n = 10) of these studies did not detect a statistically significant association between progesterone elevation and the probability of pregnancy. Meta-analysis was performed only for the studies (n = 5) that provided data on clinical pregnancy per patient reaching hCG administration for final oocyte maturation. No statistically significant association between progesterone elevation and the probability of clinical pregnancy was detected (Odds ratio: 0.75, 95% confidence interval 0.53-1.06; P = 0.10). This finding persisted in the sensitivity analyses performed, which excluded the studies that did not report clearly that measurement of progesterone did not affect patients' management and those that did not report definition of clinical pregnancy. In addition, subgroup analyses were conducted on the basis of type of gonadotrophin-releasing hormone GnRH analogue used and on the value of serum threshold used to classify patients in those with or without progesterone elevation. These analyses, however, did not materially change the results obtained. In conclusion, the best available evidence does not support an association between progesterone elevation on the day of hCG administration and the probability of clinical pregnancy in women undergoing ovarian stimulation with GnRH analogues and gonadotrophins for IVF.

The primary end-point of the present study was to verify the effect of PL on the pregnancy rate (PR) of our oocyte-donation programme. METHODS PL was defined as serum progesterone > or = 1.2 ng/ml on the day of HCG. We analysed retrospectively 240 oocyte-donation cycles in which 120 women donated twice, with PL in the first donation cycle and no PL in the following one, acting as its own control. Recipients (n = 240) were divided in two groups according to the presence of PL (n = 120) or not (n = 120). Both groups were compared regarding donor cycle parameters and recipient cycle outcome. RESULTS There was no difference in PR between the groups (55.7 versus 54.4%, respectively). The number of total oocytes (18.2 +/- 0.6 versus 20.8 +/- 0.6; P = 0.003) and the number of mature oocytes retrieved (16.9 +/- 0.6 versus 19.4 +/- 0.6; P = 0.005) were different among donors with progesterone < 1.2 ng/ml and PL, respectively. There were no differences between the oocyte recipients in fertilization, cleavage, embryo division on day 3, blastocyst development or fragmentation rates. The number of embryos transferred, number of embryos cryopreserved, and implantation and miscarriage rates were similar between the groups. CONCLUSION PL does not appear to have a negative impact on ongoing PR in our oocyte-donation programme.

Abstract
Different studies dealing with the start of progesterone supplementation in assisted reproduction treatment cycles have shown that the problem apparently is the correct timing. We therefore would like to discuss the data on: (i) the start of progesterone replacement in oocyte donation programmes; (ii) the start of progesterone replacement in frozen-thawed hormone-supplemented cycles; (ii) the problem of too early a rise of progesterone in fresh IVF cycles as a model of too early an administration of progesterone; and (iv) the benefit of high progesterone levels on the day of embryo transfer in fresh IVF cycles. From the data reviewed in this paper it seems to be appropriate to start progesterone administration before transfer in oocyte donation programmes as well as transfer of cryopreserved/thawed cells as soon as the endometrium is developed sufficiently (> or =8 mm, trilaminar pattern), and to perform the embryo transfer not before day 3-4 of progesterone treatment, i.e. embryo development on day 2-3. Studies dealing with the influence of too early a rise of progesterone in fresh IVF cycles have shown different results. In fact high progesterone levels seem to reflect a high response but not a lower probability of conception. Furthermore, high progesterone levels on the day of embryo transfer in fresh IVF cycles could lower myometrial contractility and therefore increase implantation rates. Since the experience from oocyte donation programes shows the benefit of a longer preparation time using progesterone, and high progesterone levels seem to have a benefit during embryo transfer, this would suggest extending progesterone administration before transfer. However, we have to find the optimal individual transfer protocol after mock cycles, for example with pinopode detection or other methods applicable in routine IVF programmes. We need more studies to be sure whether reproductive outcome after transfer of cryopreserved-thawed cells in estrogen/progesterone supplement cycles is influenced by the duration of progesterone pretreatment. If this is so, we must look for practicable methods to modify the protocols according to the individual patient, the embryonic developmental stage during transfer and other variables.

Abstract
Premature LH and progesterone surges are associated with different factors and hormonal modulators. The aim of the present study was (i) to investigate the clinical and laboratory factors and (ii) to highlight the importance of different stimulation protocols in associated premature LH and progesterone surges in intrauterine insemination (IUI) cycles. The study involved a retrospective investigation of 75 patients undergoing IUI for infertility treatment (135 IUI cycles) between 1996 and 2000, with initial serum LH concentrations >10 mIU/ml during ovarian stimulation. Ultrasound characteristics, follicular sizes, serum oestradiol, progesterone and LH concentrations and ovarian stimulation protocols were measured. There was a wide range of oestradiol serum concentrations (93-2245 pg/ml) and follicular size (12-25 mm). In 49.6% of cycles, the dominant follicle was <16.5 mm. Patients with >2 follicles measuring <15 mm had higher oestradiol serum concentrations (P = 0.008). Multiple regression analyses revealed no association between these variables and premature LH/progesterone surge. In conclusion, LH/progesterone surges cannot be predicted utilizing clinical parameters normally employed, e.g. ultrasound serum oestradiol assay or ovarian stimulation protocol. Patients with follicles >14 mm or more and with high numbers of small follicles and high oestradiol are at risk of a spontaneous LH surge. These variables can be used to time the administration of GnRH antagonist administration until better predictive factors are demonstrated.

Abstract
OBJECTIVE To evaluate the association between serum P levels on the day of hCG administration and the outcome of intracytoplasmic sperm injection (ICSI). DESIGN Retrospective case study. SETTING Assisted reproduction unit of a tertiary care private hospital. PATIENT(S) Nine hundred eleven ICSI cycles that proceeded to ET were studied. INTERVENTION(S) The decision to administer hCG was based on serum E2 levels and follicle size. Serum P was measured from frozen sera obtained on the day of hCG administration. Cycles were stratified according to serum P levels of <0.9 ng/mL (n = 298) or > or =0.9 ng/mL (n = 613). This cutoff level was selected because it yielded the highest sensitivity and specificity according to a receiver operator characteristic curve. MAIN OUTCOME MEASURE(S) Implantation and clinical pregnancy rates. RESULT(S) In cycles with high serum P levels, more oocytes were retrieved and more embryos were available for transfer. Clinical pregnancy rates per ET in the low and high P groups were 36.9% and 45.4%, respectively (P<.05). The implantation rate per embryo was similar in the two groups (14.9% and 16.4%, respectively, in cycles with P levels <0.9 vs > or =0.9 ng/mL). Abortion rates were 22.7 and 25.8%, respectively (P>.05). CONCLUSION(S) Our data showed no adverse effect of high serum P levels on the day of hCG administration on implantation rates after ICSI and ET.

Abstract
OBJECTIVE To determine whether premature progesterone elevation affects the timing of hyperechogenic transformation of the endometrium during the early luteal phase of controlled ovarian hyperstimulation (COH) cycles. DESIGN Prospective analysis. SETTING Assisted Reproduction Unit, Hôpital Antoine Béclère, Clamart, France. PATIENT(S) Fifty-nine women undergoing 59 IVF-ET cycles. INTERVENTION(S) Patients underwent COH with a GnRH agonist and hMG. Endometrial echogenicity was assessed on the days of hCG administration, oocyte retrieval, and ET. Results are expressed as the extent of submyometrial hyperechogenic area in relation to the total endometrial surface as determined by a computer-assisted analysis system. Patients were sorted according to whether their plasma progesterone level exceeded 0.9 ng/mL (n = 26) or not (n = 33) on the day of hCG administration. MAIN OUTCOME MEASURE(S) Endometrial echogenicity. RESULT(S) On the day of hCG administration, the degree of endometrial echogenicity was similar in both groups (41% vs. 40%), but after hCG administration, it increased significantly faster in the high progesterone group than in the low progesterone group (70% vs. 63% at oocyte retrieval and 90% vs. 79% at ET, respectively). CONCLUSION(S) End-follicular phase elevation in plasma progesterone (>0.9 ng/mL on the day of hCG administration) was associated with a faster increase in endometrial echogenicity during the early luteal phase of COH cycles. This observation is consistent with the hypothesis that premature progesterone elevation hastens the secretory transformation of the endometrium.

Abstract
While the number of identified substances produced by the ovary increases steadily, it remains remarkable that the sole use of exogenous estrogen (E2) and progesterone (P) can prime optimal endometrial receptivity in women whose ovaries have failed or are absent. Early work showed that a marked leeway existed in the acceptable duration of the E2-only phase of endometrial priming. Subsequently, a sequence of transformations are induced by exogenous progesterone that reproduces classical findings made in the menstrual cycle. Secretory changes in endometrial glands are best seen between the 4th and 6th day of progesterone administration (day 18-20 of an ideal cycle where progesterone exposure starts on day 15). Predecidual changes of the endometrial stroma are apparent starting on the 10th day of progesterone exposure (day 24). Contrary to earlier belief, even maximal alterations in the plasma E2 to progesterone ratio fails to alter the endometrial morphology of either glands or stroma. More recently it has been recognized that E2 and progesterone also affect uterine contractility. It has been postulated that excessively high levels of E2 may increase uterine contractility and adversely affect implantation rates in in-vitro fertilization (IVF). Exogenous progesterone has been shown to exert utero-relaxing effects and it has been hypothesised that progesterone supplementation before embryo transfer (ET) may improve receptivity in IVF.

Abstract
OBJECTIVE To investigate whether the consequences of premature P elevation on IVF-ET outcome are modulated by the quality of the ovarian response to controlled ovarian hyperstimulation (COH). DESIGN Retrospective analysis. SETTING Assisted Reproduction Unit, Clamart, France. PATIENT(S) One thousand twelve women undergoing 1,189 IVF-ET cycles. INTERVENTION(S) Patients underwent COH with a time-released GnRH agonist and hMG. The ovarian response to COH was classified as strong (< or = 50 hMG ampules, peak E2 levels > 2,500 pg/mL, and > or = 10 mature oocytes; n = 340), weak (> 50 hMG ampules, peak E2 levels < or = 1,500 pg/mL, and < or = 5 mature oocytes; n = 285), or intermediate (remaining cases; n = 564). The IVF-ET outcome in each group was analyzed according to whether or not plasma P levels exceeded 0.9 ng/mL. MAIN OUTCOME MEASURE(S) Pregnancy rates (PRs). RESULT(S) Clinical PRs were similar irrespective of low or high P levels in the strong (30% and 34%, respectively) and intermediate (31% and 30%, respectively) groups. However, in the weak group, P levels > 0.9 ng/mL were associated with lower PRs (3.2% and 23%, respectively). CONCLUSION(S) In the presence of an adequate response to COH, P levels > 0.9 ng/mL were not associated with lower PRs, indicating that good embryo quality may compensate for the adverse endometrial effects of P. Conversely, when the response to COH was weak, premature P elevation led to drastically reduced PRs.

Abstract
OBJECTIVE To clarify whether embryo development to the blastocyst stage may be affected by premature P elevation during controlled ovarian hyperstimulation (COH) for IVF-ET with embryo coculture. DESIGN Retrospective study. SETTING Tertiary care infertility center. PATIENT(S) One hundred thirty-one women undergoing 153 IVF-ET cycles with embryo coculture. INTERVENTION(S) Patients underwent COH with GnRH agonist and hMG. Embryos were cocultured up to the blastocyst stage. According to plasma P levels on the day of hCG, two groups were defined: low P (P < or = 0.9 ng/mL; conversion factor to SI unit, 3.180) and high P (P > 0.9 ng/mL). MAIN OUTCOME MEASURE(S) Blastulation (number of blastocysts/number of noncavitating embryos x 100) and pregnancy rates (PRs). RESULT(S) Blastulation rates were similar in the low and high P groups (51% and 48%, respectively). Moreover, patients included in the high P groups achieved significantly lower clinical and ongoing PRs (12% versus 29% and 7% versus 25%, respectively). CONCLUSION(S) The lack of difference in blastulation rates between the groups further supports the hypothesis that premature P elevation does not alter oocyte and embryo quality. Hence, the observed decrease in PRs is likely to reflect impaired endometrial receptivity in the high P group.
