FSH and LH response to LHRF in Kallman's syndrome.

The olfacto-genital syndrome (Kallman's syndrome) is believed to be primarily an hypothalamic disorder resulting in hypogonadotropic hypogonadism or hypo-ovarianism and anosmia. The pituitary response in 2 patients was measured on dialy subcutaneous injections of 100 mug of LHRF. One of the patients was also studied in a similar fashion by administration of LHRF intravenously for 4 consecutive days. A greater response occurred with the subcutaneous route.
