Abstract STUDY QUESTION Does oestrogen dose tapering during the luteal phase affect the clinical outcome after hormone replacement treatment–frozen-thawed embryo transfer (HRT-FET) cycles? SUMMARY ANSWER Our results suggest that tapering oestrogen doses during the luteal phase results in similar clinical outcomes to those obtained with the traditional luteal phase support (LPS). WHAT IS KNOWN ALREADY Traditional LPS with oestrogen and progesterone is considered necessary in HRT-FET cycles. However, case reports have shown successful clinical pregnancies and live births in the absence of oestrogen administration after embryo transfers. STUDY DESIGN, SIZE, DURATION This was a retrospective study on 6035 HRT-FET cycles extending over 7 years from January 2011 to June 2018 at the reproductive medicine centre of Xiangya Hospital. PARTICIPANTS/MATERIALS, SETTING, METHODS We compared the clinical outcomes of 1632 HRT-FET cycles with tapered oestrogen doses from 12 days after embryo transfer (study group) to those of 4403 HRT-FET cycles maintained on constant oestrogen doses during the luteal phase (control group) in the case of positive serum HCG test. MAIN RESULTS AND THE ROLE OF CHANCE We found similar biochemical pregnancy rates (52.1% vs. 51.9, P = 0.864), clinical pregnancy rates (44.9% vs. 43.2%, P = 0.249), implantation rates (29.8% vs. 29.3%, P = 0.591) and miscarriage rates (16.0% vs. 14.6%, P = 0.379) between the studied groups. LIMITATIONS, REASONS FOR CAUTION Retrospective, design-associated biases are possible. In addition, some baseline characteristics differed between groups. Finally, we did not compare live birth rates between groups. WIDER IMPLICATIONS OF THE FINDINGS Our study showing similar outcomes between traditional LPS and oestrogen tapering during the luteal phase indicates that oestrogen may be cautiously tapered during the luteal phase after HRT-FET cycles.

Abstract Background The ideal protocols of endometrial preparation for polycystic ovary syndrome (PCOS) patients are lacking and need further declaration. Our objective was to compare the clinical outcomes of frozen-thawed embryo transfer (FET) with and without pretreatment gonadotropin-releasing hormone agonist (GnRHa) in PCOS patients. Methods In this retrospective cohort study, we used propensity score matching (PSM) to compare the live birth rate between patients who underwent FET with hormone replacement treatment (HRT) and patients with GnRHa pretreatment (GnRHa + HRT). Patients using GnRHa + HRT (n = 514) were matched with 514 patients using HRT. Results The live birth rate was higher in the GnRHa + HRT group compared with the HRT group with no significant difference (60.12% vs 56.03%, p = 0.073). The clinical pregnancy rate (75.29% vs 70.62%), miscarriage rate (14.20% vs 13.81%) and ectopic pregnancy rate (0.39% vs 0.19%) were similar between the two groups. The preterm birth rate in GnRHa + HRT was higher than HRT (20.23% vs 13.04%). No difference was found in live birth between GnRHa +HRT and HRT before adjusting for covariates (crude OR 1.22, 95%CI, 0.99–1.51, p = 0.062) and after PSM (OR 1.47, 95%CI, 0.99–2.83, p = 0.068). In addition, there is a marginally difference after adjusting for covariates (aOR 1.56, 95%CI, 1.001–2.41, p = 0.048), this finding with p-value close to 0.05 represent insufficient empirical evidence. Similar results were obtained after propensity score matching in the entire cohort. Conclusions GnRHa pretreatment could not improve the live birth rate in women with PCOS.

Abstract Objective The principal purpose of this study was to compare reproductive outcomes for stimulated cycles (STC) and hormone replacement cycles (HRC) for endometrial preparation before frozen-thawed embryo transfer (FET) in young women with polycystic ovary syndrome (PCOS). Methods We conducted a retrospective study of 1434 FET cycles from January, 2017 to March, 2020 in our reproductive center, in which stimulated and hormone replacement cycles were used for endometrial preparation. Pregnancy outcomes of couples undergoing routine STC-FET or HRC-FET were analyzed before and after propensity score matching (PSM). Results Data on 1234 HRC protocols (86% of the total) and 200 STC protocols (14%) were collected. After PSM, 199 patients were included in both groups, respectively. There was no significant difference in positive pregnancy rate (52.7% vs. 54.8%, p = 0.763), clinical pregnancy rate (51.8% vs. 52.8%, p = 0.841), live birth rate (45.2% vs. 43.7%, p = 0.762), pregnancy loss rate (9.7% vs. 16.2%, p = 0.164) and ectopic pregnancy rate (1.5% vs. 0.5%, p = 0.615) between STC protocols and HRC protocols. Conclusion STC for endometrial preparation had similar pregnancy outcomes compared with HRC protocols by excluding heterogeneous factors after PSM. Evidence is available which shows that for young women with PCOS who were undergoing in-vitro fertilization, HRC could be a reasonable choice for patients who are unwilling to accept injections. Additionally, STC may offer more flexibility for young PCOS patients and reproductive centres.
