title: [Ovulation induction by endogenous LH released by the administration of an LHRH agonist after follicular stimulation for in vitro fertilization].
abstract: Sixty-seven patients whose ovulation was stimulated following a protocol of Clomiphene Citrate/HMG in order to carry out in vitro fertilisation were divided randomly in to two groups. In the first group ovulation was provoked by giving 10,000 IU HCG IM, but in the other group ovulation was provoked by releasing endogenous LH after the administration of Triptoreline in a dose of 0.1 mg in a dose subcutaneously three times in one day at 8 hour intervals. The number of oocytes recovered, cleavage and embryo transfer were compared between the two groups over 48 cycles. The number of conceptions was statistically significantly higher in the group that had triptoreline (28%) as compared with 17.4% pregnancies in the other group (p less than 0.01). These figures confirm that the endogenous LH surge provoked by giving an LHRH agonist can cause adequate final oocyte maturation. This property which is associated with a very low risk of hyperstimulation, should make it possible to stimulate ovulation when it is not used for IVF and so replace the usual injection of chorionic gonadotrophins.
