Clinical trials: Cumulus Cell
Increased Oocyte Death, in Vitro Maturation
GREM1, HAS2 and PTGS2 Gene Expression Following the in Vitro Maturation (IVM)
Poor ovarian reserve (POR) is an adverse prognostic factor for In-Vitro Fertilization (IVF) success. Numerous established data showed low live birth rates per IVF cycle; 6 to 10%, including the usage of In-Vitro Maturation (IVM).

OVARIAN STIMULATION, Telomere Length
Does Recombinant FSH (rFSH, i.g. Gonal F®) as Compared to Human Menopausal Gonadotrophin (hMG) Affect Telomere Length of Cumulus Cells During Antral Follicle Growth and Impact Blastocyst Status?
Gonal-F® (follitropin alfa) is a recombinant FSH without LH activity, while Menopur® contains both LH and hCG. The MEGASET trial compared Menopur® and Gonal-F® in GnRH antagonist cycles with SET, showing similar efficacy.
