[Ovulation induction using pulsatile GnRH in patients with hypothalamic amenorrhea: effects of changing the frequency and dosage on the luteal phase].

Effects of frequency and dose variation of GnRH administration by minipumps Zyklomat, were studied in five women during luteal phase. As controls were assumed the same patients; in fact they had been previously treated with pulsatile GnRH with constant dose and frequency all over the cycle. Then the patients received the same treatment but the dose and the frequency of infusion were changed in the luteal phase. Our data show an increase of mean levels of progesterone and oestradiol during the luteal phase and a better pregnancy rate when the frequency and the dose of GnRh administration were changed.
