Summary: This study found that for women with previous cesarean sections, the pregnancy outcomes were similar to those with previous vaginal delivery in single embryo transfer cycles, and the presence of cesarean scar defect (CSD) was associated with a significant reduction in live birth rate, especially in patients with large CSD.

Summary: This study found that women with a caesarean scar without defects had similar reproductive outcomes after IVF or ICSI compared to women with a history of vaginal delivery. However, women with a caesarean section defect, especially young women (<=35 years old), significantly reduced their chances of subsequent pregnancy.

Summary: Previous cesarean section has a negative impact on biochemical pregnancy and live birth rates in post-embryo transfer pregnancies, compared to previous vaginal delivery. There is an increased risk of preterm birth in post-fresh embryo transfer pregnancies.

Summary: This meta-analysis investigates the impact of recryopreservation on embryo viability and the outcomes of in vitro fertilization (IVF). The findings suggest that recryopreservation can result in decreased embryo survival, clinical pregnancy rates, and live birth rates compared to single cryopreservation.

Summary: This study evaluated the reproductive outcomes of patients with previous cesarean section undergoing single-embryo transfer (SET). The results showed that patients with previous CS and VD had similar CPR and LBR, but CS patients had a significantly higher preterm birth rate in multiple births compared to VD. In IVF/ICSI and FET cycles, patients under 35 years old treated with SCT had lower CPR and LBR, and patients over 35 years old had even lower rates.

Summary: The study highlights the importance of accurate diagnosis using transvaginal sonography in the first trimester for patients with heterotopic cesarean scar pregnancy, particularly those with a history of in vitro fertilization-embryo transfer. It recommends single embryo transfer for such patients and suggests that expectant management may offer a chance for live cesarean scar pregnancy development, albeit with risks that need further verification in the future.

Summary: The study found an association between IVF treatment and offspring neoplasm risk, especially for offspring transferred as fresh embryos, at an earlier embryotic stage, or after harvesting three or more oocytes.

Summary: The study results indicate that an increase in sperm DFI significantly reduces the success rate of fresh embryo transfer cycles, as well as the biochemical pregnancy rate and clinical pregnancy rate of frozen embryo transfer cycles.

Summary: This study aimed to investigate the optimal timing of embryo transfer for patients with isthmocele to minimize the risk of Cesarean Scar Pregnancy (CSP). The results showed that embryo transfer at the blastocyst stage on day 5 seemed to significantly reduce the risk of CSP.

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 evaluated the effects of zona pellucida removal on the in vitro and in vivo development of domestic cat embryos. Results showed that removal of the zona pellucida negatively impacted gene expression and prevented successful implantation of the embryos.

Summary: With the rapid urbanization and industrialization in China, air pollution has become a significant environmental issue. A retrospective data analysis of 6564 patients from the Center for Reproductive Medicine at the First Affiliated Hospital of Zhengzhou University between 2015 and 2020 revealed that air pollutants have a significant impact on the outcome of in vitro fertilization and embryo transfer (IVF-ET), particularly in patients younger than 35 years old, those undergoing single embryo transfer, and cleavage stage embryo transfer.

Summary: This study found significant differences in female serum zinc levels between Beijing and Shandong centers. Lower zinc concentrations in Shandong may be a risk factor for IVF-ET failure, which can be addressed by adjusting dietary intake.
