Ovulation induction for in vitro fertilisation using clomiphene citrate and low-dose human menopausal gonadotrophin.

Ovulation induction using a low dose of human menopausal gonadotrophins and clomiphene citrate for in vitro fertilisation and embryo transfer is described. Sixty-two cycles of ovulation induction were initiated in 37 patients. Forty-six laparoscopies were performed, yielding 116 oocytes. Of these, 90 (77.6%) cleaving embryos developed, and in 36 transfers 10 pregnancies (27.8%) were established. The use of low-dose hMG in conjunction with a programme on an outpatient basis may prove to be optimal for the purpose of in vitro fertilisation and embryo transfer.
