[Induction of ovulation using pulsatile GnRH administration to infertile females]

6 infertile women with primary or secondary amenorrhoea or anovulation, who failed to ovulate after clomiphene and HMG/HCG treatment, underwent 11 treatment cycles with pulsatile GnRH therapy using a portable pump. Normal ovulation occurred in 9 out of 11 treatment cycles; the luteal phase was normal in 6 cycles. One woman conceived in the second treatment cycle.
