Conclusion
This study highlights that age, BMI, E2, and number of follicles ≥12mm at trigger can predict oocyte yield in SEF cycles. As such, individualising SEF cases with consideration of these markers, should be undertaken to optimise oocyte yield. AMH and AFC are however not independently significantly associated with oocyte yield. Additionally, this is the first study to establish an incidence of OHSS in SEF cycles and establish a significant relationship between age, total AFC, number of follicles ≥12mm and FSH as predictors of OHSS. Moreover, the reproductive outcomes presented highlight that undertaking SEF over the age of 40 years is suboptimal and associated with a low chance of success. Whilst there was no significant difference in livebirth rates in women ≤35 years and aged 36-39, it is advisable that SEF should be undertaken at or prior to the age 36 to optimise outcomes. This data has significant implications for clinical practice, and can be used to individualise care, enhance counselling and manage expectations in women undergoing SEF.
