Long Antagonist Protocol for IVF With Single Luteal Dose of Degarelix

Long Antagonist Protocol for IVF: a Proof of Concept for a Single Luteal GnRH- Antagonist Protocol

A prospective study of three different doses of Degarelix in late luteal phase of women undergoing ovarian stimulation for IVF

A prospective study of three different doses of Degarelix in late luteal phase of women undergoing ovarian stimulation for IVF:Single dose of Degarelix 24mg, 16mg and 12 mg, on day 24th of previous luteal face cycle. On day 2 of the cycle: will be measured: LH levels, estradiol levels, and FSH levels.

ON day 1 of the stimulation (depending day of the cycle): will be measured: LH levels, estradiol levels, and FSH levels.

On day 6 of the stimulation( depending day of the cycle):will be measured: LH levels, estradiol levels, and FSH levels.

On day 8 of the stimulation( depending day of the cycle):will be measured: LH levels, estradiol levels, and FSH levels.

On day 10 of the stimulation( depending day of the cycle):will be measured: LH levels, estradiol levels, and FSH levels.
