Clinical and Live Birth Rates After Following Long Antagonist Protocol Versus Long Agonist Protocol

Clinical and Live Birth Rates After Controlled Ovarian Stimulation With the Long Antagonist Protocol Versus the Long Agonist Protocol

A prospective study of the evaluation of the clinical IVF (in vitro fertilization) results after following Long Antagonist protocol for Controlled Ovarian Stimulation (COS) versus following Long Agonist protocol

A prospective study of the clinical results in women who followed the Long Antagonist protocol for Controlled Ovarian Stimulation (COS) versus women who followed Long Agonist protocol, in an In Vitro Fertilization (IVF) try. In particular, the Clinical Pregnancy Rates (CPR) and Live Birth Rates (LBR) were estimated for the two groups of patients. The number of the formed blastocysts was also measured in each group of patients.
