[In vitro maturation: the French experience]

Abstract

In vitro oocyte maturation (IVM) allows the use of immature oocytes in IVF. IVM does not require ovarian stimulation and therefore can be offered to patients at risk of ovarian hyperstimulation syndrome. IVM can be offered as an alternative to conventional IVF in women with PCOS (polycystic ovarian syndrome). However, cleavage, implantation, and pregnancy rates were lower than those obtained with conventional IVF. The present study describes the results of IVM in French IVF departments.
