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

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

A randomized prospective study of the evaluation of the clinical IVF results after following Long Antagonist protocol for controlled ovarian stimulation versus following classical antagonist protocol

A randomized prospective study of administration of Degarelix in late luteal phase of women undergoing ovarian stimulation for IVF: Single dose of Degarelix (24mg, 16mg or 12 mg), on day 24th of previous luteal face cycle, was administered. The Clinical Pregnancy and Live Birth Rates were estimated for this group of patients, comparing to the rates of the group which followed classical antagonist protocol. The number of the formed blastocysts in each group is measured, as well.
