Association of estrogen, progesterone and follicle stimulating hormone receptor polymorphisms with in vitro fertilization outcomes.

Unlabelled: Despite the advances in in vitro fertilization (IVF), the implantation success rate for infertile women remains approximately only 15%. In this study, we sought to determine whether implantation failure after repeated IVF treatments is influenced by the presence of common variants in estrogen α, progesterone and follicle stimulating hormone receptor genes. The study population included three groups of women: group 1 were 50 women who had the transfer of ≥3 high-quality embryos during the IVF procedure without ever having had a clinical pregnancy; group 2 were 50 women who achieved a clinical pregnancy after ≤3 high-quality embryos transfers and group 3 were 50 control subjects who achieved a clinical pregnancy without any fertility therapy that resulted in a one live-born infant.
