Summary: This study aimed to investigate the effect of storage duration of vitrified warmed embryos on pregnancy and neonatal outcomes. The results showed that within a storage period of up to 7 years, there was no impact on the pregnancy and neonatal outcomes of embryos after vitrification.

Summary: This study aimed to investigate the relationship between endometrial thickness and early pregnancy complications in frozen thawed embryo transfer cycles. The results showed that thin endometrium was associated with an increased risk of ectopic pregnancy and early spontaneous miscarriage. Therefore, endometrial thickness can serve as an independent predictor for early pregnancy complications.

Summary: Sequential transplantation is a new mode of in vitro fertilization and embryo transfer. This study compared the clinical outcomes of sequential transplantation, embryo transplantation, and blastocyst transplantation in freeze-thaw embryo transfer cycles. The results showed that the sequential transplantation group had a significantly higher number of transplanted embryos than the other two groups, and the blastocyst transplantation group had the highest implantation rate. The sequential transplantation cycle can achieve a higher clinical pregnancy rate and minimize wastage of transplanted embryos, making it a viable choice for some patients in resuscitation transplantation cycles.

Summary: This study examined the effect of COVID-19 infection or vaccination on frozen-thawed embryo transfer (FET), and found that these factors did not affect patients' performance or implantation in subsequent FET cycles.

Summary: This study evaluated the pregnancy and neonatal outcomes in women who had undergone wedge resection for interstitial pregnancy during frozen-thawed embryo transfer cycles. The results showed that women with previous wedge resection were at a higher risk of ectopic pregnancy and uterine rupture, but there were no significant differences in clinical pregnancy rate, live birth rate, and neonatal outcomes. The study recommended cesarean section for these patients and further studies are needed to validate the current recommendations.

Summary: In this large-sample retrospective study, the incidence of ectopic pregnancy (EP) in frozen embryo transfer (FET) cycles was found to be slightly lower than fresh embryo transfer (ET) cycles, with no significant difference. Among patients undergoing ET cycles, the long agonist protocol was associated with a significantly lower risk of EP compared to the GnRH antagonist protocol.

Summary: The effects of serum estrogen levels on pregnancy outcomes in hormone replacement cycles were investigated. The study found that the serum estrogen levels before frozen-thawed blastocyst transfer did not affect pregnancy outcomes, and age was found to be an independent factor affecting clinical pregnancy.

Summary: The study found that embryos transfer impacts fetal cardiac remodeling and suboptimal function, with more pronounced changes after fresh embryo transfer compared to frozen embryo transfer. Fetuses conceived by assisted reproductive technologies showed larger atria, more globular ventricles, and thicker myocardial walls, as well as signs of suboptimal systolic and diastolic function as compared to spontaneously conceived pregnancies.

Summary: Among women of advanced maternal age, there was no significant difference in live birth rates between frozen embryo transfer and fresh embryo transfer. However, frozen embryo transfer resulted in higher birthweights and a lower incidence of preterm births.

Summary: The study found that the method of embryo transfer did not significantly impact early placental development, but frozen-thawed embryo transfer had a beneficial impact on uterine artery Doppler indices in the second and third trimesters.

Summary: Low-dose aspirin is commonly used in frozen-embryo transfer (FET) cycles, but the effect of short-term aspirin administration on pregnancy outcomes is unclear. In this retrospective study, we analyzed the outcomes and complications of 4454 programmed FET cycles and found that the short-term use of aspirin did not improve live birth rates or reduce the incidence of pregnancy complications. Based on our findings, short-term administration of low-dose aspirin may not benefit young women undergoing frozen-thawed embryo transfer cycles.

Summary: Embryo development speed and morphology score are important factors in frozen-thawed embryo transfer (FET) outcomes. D5 embryos are generally preferred over D6 embryos, but there is some variation in clinical outcomes. This study found that AA/AB blastocysts showed similar pregnancy outcomes regardless of development day, while BA/BB/BC blastocysts had better outcomes on D5 than D6. Comparing BC embryos on D5 and BA/BB embryos on D6, no differences were observed in clinical pregnancy outcomes and neonatal outcomes, but D6 BA/BB embryos had a higher miscarriage rate, which was not statistically significant after adjusting for confounding factors.

Summary: This study compared the safety and efficacy of low-dose subcutaneous progesterone with vaginal progesterone for luteal-phase support in frozen-thawed embryo transfer patients. The results showed a slightly higher pregnancy rate with vaginal progesterone, but the difference was not statistically significant.
