Brief and long co-incubation of sperm and oocytes for in vitro fertilization: a meta-analysis of randomized controlled trials

Yiyue Fan et al.

Summary: This meta-analysis compared the effects of brief (1-6 h) and long (16-24 h) gametes co-incubation time on IVF outcomes. The results showed that brief co-incubation had advantages in increasing implantation rate, ongoing pregnancy rate, and top-quality embryo rate compared to long co-incubation. However, there was no difference in live-birth rate and other outcomes. Therefore, the co-incubation time should be individualized based on each patient's IVF history, infertility causes, and semen parameters.

Comparison of embryonic competence and clinical outcomes between early and late cumulus cell removal for in vitro fertilization

Pallop Pongsuthirak

Summary: This study found that early and late cumulus cell removal during in vitro fertilization did not significantly impact fertilization, polyspermy, embryo quality, and pregnancy outcomes. Early cumulus cell removal combined with early rescue ICSI may be helpful for couples experiencing total fertilization failure (TFF).

Effects of Early Cumulus Cell Removal on Treatment Outcomes in Patients Undergoing In Vitro Fertilization: A Retrospective Cohort Study

Pengcheng Kong et al.

Summary: The study concluded that early cumulus cell removal alone did not have adverse effects on pregnancy and neonatal outcomes, and it is considered a safe option for patients undergoing IVF to assess for potential early rescue ICSI.

The Function of Cumulus Cells in Oocyte Growth and Maturation and in Subsequent Ovulation and Fertilization

Bongkoch Turathum et al.

Summary: Cumulus cells play a vital role in supporting oocyte growth, maturation, and developmental competence. Their function is essential for oocyte meiotic maturation, ovulation, fertilization, and early embryo development. Understanding the role of cumulus cells is crucial for predicting oocyte quality, embryonic development competence, and pregnancy outcomes in reproductive medicine and infertility treatment.
