Abstract This study was to investigate effects of progesterone vaginal sustained-release gel and intramuscular injection of progesterone on frozen-thawed embryos transfer in 3013 patients receiving vaginal progesterone sustained-release gel and progesterone injection in artificial cycle for frozen-thawed embryo transfer. All patients were divided into two groups: group A with progesterone intramuscular injection (60 mg/d) plus dydrogesterone (10 mg tid) and group B with progesterone vaginal sustained-release gel of progesterone (90 mg/d) plus dydrogesterone (10 mg tid). There were 1988 women in group A treated with progesterone injection and 1025 women in group B with progesterone vaginal sustained-release gel. There were no statistically (P > 0.05) significant difference between the two groups in age, years of infertility, body mass index, endometrial thickness at transfer time, the average numbers of embryo transferred, cause of infertility, number of cycles, pregnancy rate and ectopic pregnancy rate. No significant (P > 0.05) differences existed in the clinical pregnancy (52.5% vs. 56.0%) and ectopic pregnancy (2.2% vs. 3.0%) rate between groups A and B. However, group B with vaginal progesterone supplementation had significantly (P < 0.05) greater implantation (37.0% vs 34.4%), delivery (45.1% vs. 41.0%) and live birth (45.0% vs. 40.8%) rate than group A with intramuscular progesterone injection, whereas group A had significantly (P < 0.05) greater early abortion rate (19.4% vs. 15.3%) than group B. This study showed that vaginal gel progesterone supplementation has good effects on frozen-thawed embryo transfer and can significantly increase the rate of implantation, delivery and live birth but decrease the abortion rate compared with intramuscular progesterone injection.

Abstract Background: Previous studies have demonstrated that newborns from fresh embryo transfer are with higher risk of small for gestation (SGA) rate than those from frozen-thawed embryo transfer (FET). It is suggested that supraphysiologic serum estradiol in controlled ovarian stimulation (COS)is one of reasons. Out study aims to investigate whether exogenous estradiol delivered regimens have an impact on live birth rate and singleton birthweight in hormone replacement (HRT)-FET cycles.Methods:This retrospective study involved patients undergoing their first FET with HRT endometrium preparation followed by two cleavage-staged embryos transfer, comparing orally and vaginal estradiol tablets (OVE) group versus oral estradiol tablets (OE) group from January 2015 to December 2018 at our center. A total of 792 patients fulfilled the criteria, including 282 live birth singletons. Live birth was the primary outcome. Secondary outcome included clinical pregnancy rate, singleton birthweight, large for gestational age (LGA) rate, SGA rate, preterm delivery rate. Results:Patients in OVE group achieved higher serum estradiol level with more days of estradiol treatment. No difference in live birth (Adjusted OR 1.327; 95%CI 0.982, 1.794, p=0.066) and clinical pregnancy rate (Adjusted OR 1.278; 95%CI 0.937, 1.743, p=0.121) was found between OVE and OE groups. Estradiol route did not affect birth weight (β=-30.962, SE=68.723, p=0.653), the odds of LGA (Adjusted OR 1.165; 95%CI 0.545, 2.490, p=0.694), the odds of SGA (Adjusted OR 0.569; 95%CI 0.096, 3.369, p=0.535) or the preterm delivery rate (Adjusted OR 0.969; 95%CI 0.292, 3.214, p=0.959).Conclusion:Estrogen orally and vaginally together did not have an impact on clinical outcomes and singleton birthweight compared to estrogen orally taken, but was accompanied with relative higher serum E2 level and potential maternal undesirable risks.

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.

Background: Cryopreservation's success rate varies depending on woman age, as low as 14.8% (if eggs were extracted from 40-year-old women), and as high as 31.5% with 25-year-old women. The goal of the research is to improve laboratory methods for freezing-thawing embryos, leading to elevated embryo survival rate. Yet, in hormonal replacement therapy frozen-thawed embryo transfer (HRT-FET) cycles, effective endometrial preparation before embryo transfer attracted less focus. The present research’s aim is to see whether there's a link between blood progesterone levels and pregnancy rates the day before frozen-thawed embryo transfer. Methods: This prospective observational research has investigated 120 patients of frozen-thawed embryo transfer cycle treatment, only 100 individuals subdivided to 2 groups for serum level of progesterone one day before frozen-thawed embryo transfer. The subjects visited both the Obstetrical and Gynecological Department of Tanta University as well as private centers between May 2020 and January 2021. Results: We discovered no correlation between maternal age with pregnancy test results. Yet, our study discovered highly significant variation among both groups regarding endometrial thickness one day preceding embryo transfer, and regarding pregnancy rate (p<0.05). Conclusion: The serum progesterone hormone preceding frozen embryo transfer has significant and direct relation and impact upon pregnancy rates. The present research detected low serum progesterone less than 10 nanograms/ml in the day before frozen-thawed embryo transfer in HRT-FET cycles significantly decreased probability of ongoing pregnancy post frozen-thawed embryo transfer.
