Apoptosis and pAKT levels in cumulus cells of patients undergoing in vitro fertilization program with specific polymorphisms of gonadotropins and their receptors: a case-control study.

Study question Is there a difference in oocyte competence among patients with different gonadotrophin polymorphisms, after ovarian stimulation with r-FSH? Summary Answer Higher DNA Fragmentation Index and cleaved caspase-3 related to lower level of pAKT has been observed in patients with specific gonadotrophin polymorphism (FSHR and LHB). What is known already • In our experience, the DFI, the percentage of cleaved caspase-3 and the pAKT on cumulus cells can be used as molecular markers of oocyte competence; • The polymorphic variant of LHB is characterized by an extra glycosylation signal into the β subunit. This molecular variation influences the pharmacokinetic properties of v-betaLH, sh…
