Gonadotropin ovulation induction and pregnancies in women with Kallmann's syndrome.
Only 17 cases of pregnancy in women with Kallmann's syndrome have been reported in the literature, eight as case reports. In our clinic, we diagnosed seven women with complete Kallmann's syndrome in a 16-year period. In five cases (unprimed patients) the diagnosis was established for the first time, while in the other two cases diagnosis had been established earlier. The five unprimed patients received hormone therapy (HRT) immediately after diagnosis. The other two patients had already been on HRT. Four patients wanted to bear children. Follicular evolution and maturation was induced with daily human menopausal gonadotropin (hMG) administration. The results were monitored through plasma estradiol (E2) determinations and ultrasonography. Ovulation was induced with hCG administration. Five pregnancies were achieved in three patients, resulting in four healthy neonates. Two women achieved a second pregnancy. Nausea and vomiting did not occur in any of our five pregnancies. We found no significant differences between the total hMG dose needed for ovulation induction, the number of stimulation days, estradiol plasma concentrations and the number of follicles with diameter > or = 17 mm, in either conceptional or non-conceptional cycles. In fact, the total hMG dose administered was lower and the days of stimulation were significantly fewer in women on their second pregnancy. There was no difference in plasma estradiol concentrations and the number of follicles with diameter > or = 17 mm. In conclusion, ovulation induction and pregnancy in women with complete Kallmann's syndrome is not such a difficult procedure as was believed in the past. A previous pregnancy seemed to augment ovarian sensitivity to gonadotropins.
