High serum FSH levels on day 7 of stimulation are negatively associated with oocyte retrieval in GnRH antagonist protocols: real-world evidence from 9,969 IVF cycles in China
Frontiers in endocrinology ·doi:10.3389/fendo.2026.1757107

This study aimed to investigate how levels of serum follicle-stimulating hormone (FSH) on Day 7 of ovarian stimulation are related to the number of oocytes retrieved, and identify any cutoff or threshold point in protocols using gonadotropi…

Follicular sphericity based on three-dimensional transvaginal ultrasound algorithms predicts ovarian responsiveness to in vitro fertilization
Journal of ovarian research ·doi:10.1186/s13048-025-01771-7

BACKGROUND: The principal indicators adopted for the assessment of follicular quality are still two-dimensional ultrasound(2D-US) imaging parameters, but these do not reflect the three-dimensional morphology of follicles. We herein aimed to…

High initial FSH dosage reduces the number of available cleavage-stage embryos in a GnRH-antagonist protocol: Real-world data of 8,772 IVF cycles from China
Frontiers in endocrinology ·doi:10.3389/fendo.2022.986438

To evaluate the relationship between the initial follicle stimulating hormone (FSH) dose and the number of available cleavage-stage embryos in in vitro fertilization (IVF) cycles.We included 8772 fresh IVF cycles using a GnRH antagonist pro…
