Association of in vitro fertilization outcome with circulating insulin-like growth factor components prior to cycle initiation
Fertilization in Vitro
Insulin-Like Growth Factor Binding Protein 1
Insulin-Like Growth Factor I
Insulin-Like Growth Factor II
Maternal serum levels of IGF-I, IGF-II, and IGFBP-1 prior to initiation of an IVF cycle are correlated with the likelihood of a live birth. Alterations in maternal IGF system components may influence oocyte quality or the success of early postfertilization events and embryo implantation.
