Intrauterine insemination and controlled ovarian hyperstimulation in cycles before GIFT.
We have combined intrauterine insemination (IUI) and controlled ovarian hyperstimulation (COH), for the treatment of infertility due to different aetiologies, prior to performing GIFT. To date, we have treated 186 patients over a total of 489 cycles. The mean age of the patients was 34.1 +/- 4 years and the mean duration of infertility was 4.8 +/- 2.8 years. Follicular development was induced with human menopausal gonatrophin (HMG). Patients were monitored using serum oestradiol determinations and ovarian ultrasound. Two intrauterine inseminations were performed 12 and 36 h after HCG injection. Semen samples were prepared utilizing one of two techniques, swim-up or Percoll gradient. A total of 33 pregnancies have occurred, the gross pregnancy rate being 17.7% per patient and 6.7% per cycle. The cumulative pregnancy rate was 30%. Thirty-one pregnancies (94%) occurred within the first four cycles of treatment. During the same period of time, the pregnancy rate per cycle in patients treated with gamete intra-Fallopian transfer (GIFT) was 32.9%. Our data suggest that IUI combined with COH can result in pregnancy in a significant proportion of patients, but that the efficiency per cycle of the technique is significantly lower than GIFT.
