Aide à l’activation ovocytaire : Un nouvel atout dans le traitement des infertilités masculines sévères [Assisted oocyte activation: a new tool for severe male factor infertility treatment]
Abstract
In severe male infertility, in vitro fertilization (IVF) with intra-cytoplasmic sperm injection (ICSI) represents the sole available therapeutic option. However this technique is not always successful in promoting fertilization, as some couples completely and repeatedly fail to obtain any embryo. In many cases, this failure can be attributed to a defective rise in intracellular calcium, which is required to achieve oocyte activation. Over the last twenty years, several laboratories dedicated to assisted reproduction technologies have been using a calcium ionophore to assist oocyte activation. The aim of this review is to give an overview of the advances and consequences associated with this new technique referred to as assisted oocyte activation
