Summary

This study uses number and size of ovarian follicles on the day of ovulation trigger as key determinants for oocytes yield to optimize outcomes in IVF and ICSI Protocols

Detailed description

Accurate prediction of oocyte yield is a key factor in optimizing outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles. Follicle number and follicle diameter measured on the day of ovulation trigger are known to be strongly associated with oocyte retrieval and oocyte maturity. Larger follicles are more likely to yield mature (metaphase-II) oocytes, while smaller follicles contribute less consistently to oocyte yield. Despite the established association between follicular size and oocyte maturity, there is currently no standardized clinical model that estimates the minimum expected number of retrieved oocytes based on the distribution of follicle diameters on the trigger day. Most existing studies focus on average outcomes rather than providing a practical tool to estimate the lowest anticipated oocyte yield for individual patients. This study aims to estimate the minimum number of oocytes retrieved based on the number and diameter of ovarian follicles measured on the day of ovulation trigger. By developing a predictive approach based on follicular size distribution, this study seeks to support clinical decision-making, optimize trigger timing, and improve patient counseling regarding realistic expectations of oocyte yield.
