Implication

Retrospective cohort study finds elevated hormone levels on hCG trigger day associate with successful oocyte retrieval, indicating clinical factors alone do not govern outcomes.

Key Points

To evaluate how clinical factors and hormonal profiles influence oocyte retrieval success during modified natural cycle assisted reproductive procedures.
Conducted a retrospective cohort study of patients undergoing IVF or ICSI cycles at a fertility clinic between 2018 and 2023.
Monitored follicular development using ultrasound and evaluated patient clinical characteristics alongside hormonal levels.
Clinical factors showed no statistically significant impact on oocyte retrieval success (p > 0.05).
Higher hormone levels measured on the day of human chorionic gonadotropin (hCG) trigger administration were associated with an increased likelihood of successful oocyte retrieval.
