Abstract:
A retrospective analysis of 844 IVF-ET cycles demonstrated that changes in E(2) levels after administration of hCG do not influence fertilization, implantation, pregnancy, or live-birth rates. In vitro fertilization cycles with a declining E(2) level have comparable success to those with no change or increasing E(2) levels and should proceed to oocyte retrieval.
