Summary: The study compared immediate and delayed frozen embryo transfers following a stimulated IVF cycle and found that immediate FET resulted in significantly higher ongoing pregnancy and live birth rates. This suggests that immediate FET may be more effective after a stimulated IVF cycle.

Summary: This large retrospective cohort study aimed to investigate the effect of female body mass index (BMI) on ectopic pregnancy (EP) following fresh and frozen-thawed embryo transfers (ET). The study found that female BMI did not affect the occurrence of ectopic pregnancy in either fresh or frozen-thawed embryo transfer cycles.

Summary: This study aimed to assess the impact of vitamin D levels on embryo quality and pregnancy outcomes in patients with normal ovarian reserve undergoing the first IVF/ICSI cycle. The findings suggest that serum vitamin D level is not associated with embryo quality and pregnancy outcomes for these patients. Further studies are needed to elucidate the relationships between vitamin D levels and IVF outcomes.

Summary: This retrospective study investigated the impact of endometrial thickness on ectopic pregnancy rate and clinical pregnancy rate in fresh embryo transfer patients with early follicular phase long-acting regimen. The results showed that endometrial thickness was positively correlated with clinical pregnancy rate and negatively correlated with ectopic pregnancy rate. When the endometrial thickness was greater than or equal to 11mm, it could achieve lower ectopic pregnancy rate and higher clinical pregnancy rate simultaneously.

Summary: This study examined the impact of maternal BMI on embryo morphokinetics and the outcomes of frozen embryo transfer cycles. The findings showed that embryos from normal-weight patients had slower cleavage rates compared to obese patients, but the quality of the embryos was similar between the BMI groups. There were no significant differences in pregnancy rate, clinical pregnancy rate, or miscarriage rate among the groups.

Summary: The study found that a single oral dose of nolasiban 900 mg significantly increased pregnancy rates in women undergoing IVF, supporting the hypothesis that oxytocin receptor antagonism at the time of embryo transfer may have a positive impact.

Summary: The quality of embryos transferred and the presence of tubal factor infertility affect the risk of ectopic pregnancy after IVF/ICSI. Transfer of top-quality embryos is associated with a lower rate of ectopic pregnancy. To reduce the risk of ectopic pregnancy, the number of embryos transferred should be minimized.

Summary: This study compared the effects of fixed estrogen dose and increasing estrogen doses during hormone therapy frozen embryo transfer (HT-FET) cycles. The results showed that despite using higher doses of estrogen and longer treatment duration, the increased-dose group had thinner endometrium. However, the pregnancy rates were similar between the two groups.

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: This study examined specific serum beta-hCG parameters for predicting live birth after an embryo transfer and found that doubling of beta-hCG levels or reaching 100 within 15 days were robust predictors of live birth.

Summary: In comparison with single good-quality embryo transfer, double embryo transfer of one good-quality embryo and one poor-quality embryo does not significantly affect the pregnancy rate but increases the rate of multiple pregnancies and multiple births.

Summary: The study aimed to use a culturomics-based method to analyze the endometrial microbiota and correlate the results with ongoing pregnancy rates. It was found that detection of bacteria by culturomics from catheter tips used for embryo transfer could offer a reliable method to detect pathogen growth. The study highlights the importance of endometrial microbiota testing in improving diagnosis and treatment strategies in IVF patients.

Summary: The study found that for women of all ages, the sustained implantation rates for day 5 good quality blastocysts were higher than for day 5 fair, day 5 poor, and day 6 blastocysts. There were also higher sustained implantation rates for younger patients compared to older patients when controlling for morphology and day of biopsy, showing that age plays a significant role in the success of implantation.

Summary: This study aimed to compare the effects of transferring 1 versus 2 low-quality blastocysts on live birth rate and multiple pregnancy rate. The results showed that in women over 40, there was no significant difference in outcomes between SET and DET, while in women under 40, DET significantly increased the multiple pregnancy rate.
