Induction of Ovulation with Gonadotrophins—A Ten Year Review

We describe the outcome of induction of ovulation with gonadotrophins (HMG/HCG) in 46 patients treated over 138 cycles. Ovulation was induced in 88 per cent of cycles and there were 43 conceptions in 33 patients with a cumulative conception rate of 96 per cent. The incidence of multiple pregnancy was 36 per cent of those reaching a gestation of 13 weeks or more and accounted for all the second and third trimester foetal losses. Overall, 61 per cent of the patients have taken home at least one healthy child. Mild symptomatic ovarian hyperstimulation complicated 9.4 per cent of courses and was more frequent among patients with normal pretreatment oestrogen levels. We found continuous biochemical monitoring of follicular growth to be a poor predictor of multiple pregnancy or hyperstimulation. We discuss our local experience with reference to published reports from other centres and in relation to recent advances in management and consider the future role of this therapy.
