Kallmann syndrome: a case of twin pregnancy and review of the literature.
In order to evaluate the possibilities for induction of ovulation, the functional competence of the pituitary gland of a woman with Kallmann syndrome was examined by two consecutive dynamic GnRH tests. The second test was conducted after 1 week's treatment by a GnRH pump. The results, which showed some rise of LH but no response of FSH, favored induction by hMG/hCG therapy. Three treatment cycles resulted in a twin pregnancy which was normal and was carried to term. Review of the literature shows only six previously reported pregnancies in women with Kallmann syndrome. Five of them were treated by hMG/hCG, and one by pulsatile GnRH. The two methods of induction are discussed in relation to the heterogeneity of the pituitary and ovarian function in Kallmann syndrome. We show that this heterogeneity dictates that the treatment for induction of ovulation should be individually adjusted according to the pituitary and ovarian competence.
