Prevalence of an endogenous LH rise following final GnRH antagonist dose in the IVF antagonist protocol.
European journal of obstetrics & gynecology and reproductive biology: X ·doi:10.1016/j.eurox.2026.100454

BackgroundThe GnRH antagonist protocol is widely used in IVF/ICSI treatments. It involves daily injections of a GnRH antagonist starting on stimulation day 5 or later to prevent premature ovulation by suppressing the endogenous gonadotropin…

Dose-dependent stimulation of human follicular steroidogenesis by a novel rhCG during ovarian stimulation with fixed rFSH dosing.
Frontiers in endocrinology ·doi:10.3389/fendo.2022.1004596

BackgroundChoriogonadotropin (CG) beta (FE 999302), a novel recombinant human (h)CG produced by a human cell line, has a longer half-life and higher potency than CG alfa produced by a Chinese hamster ovary cell line. hCG augments steroid pr…

Transcription profile of the insulin-like growth factor signaling pathway during human ovarian follicular development.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-019-01432-x

PurposeThe IGF signaling cascade exerts important regulatory functions in human ovarian folliculogenesis. The scope of this study was to evaluate the transcription profile of insulin-like growth factor (IGF) genes during human ovarian folli…
