In vitro oocyte maturation for female fertility preservation

Recovering immature oocytes from unstimulated ovaries, followed by in vitro maturation (IVM) was initially proposed to avoid the risks and side effects of exogenous gonadotropin administration. Therefore, during the past decades, IVM was mainly offered to patients with polycystic ovary syndrome at high risk of ovarian hyperstimulation syndrome. However, the development of fertility preservation has recently opened new perspectives in the field of IVM. The present review reports the possible indications of IVM, in the strategy of female fertility preservation. (C) 2014 Elsevier Masson SAS. All rights reserved.
