title: Preservation of fertility despite subnormal gonadotropin and testosterone levels after cessation of pulsatile gonadotropin-releasing hormone therapy in a man with Kallmann's syndrome.
abstract: A man with IHH and anosmia presented in 1980. He was successfully treated with various hormonal regimens; four children were conceived with hCG or pulsatile GnRH therapy. The patient discontinued GnRH after the fourth child was conceived, and testosterone enanthate injections were prescribed. However, he took the injections only briefly and 15 months later he demonstrated continuing spermatogenesis despite low serum FSH and LH levels. His wife successfully became pregnant. This case adds to the recognized range of recovery in IHH, with fertility despite stopping hormonal therapy and despite low serum gonadotropin and T levels.
