Brief Summary
The purpose of the study is to examine how Kallmann syndrome (KS) and idiopathic hypogonadotropic hypogonadism (IHH) affect reproductive hormones. These disorders are caused by a defect in Gonadotropin Releasing Hormone (GnRH) secretion. GnRH is a hormone released by a small gland in the brain called the hypothalamus. When GnRH is released, it signals another gland in the brain, the pituitary, to secrete the reproductive hormones that influence sex hormone (testosterone, estrogen) levels and gamete (sperm, egg cell) production. This study involves a detailed evaluation and 24-48 hours stay at the hospital. In this study, males and females ages 16 and older with IHH have a detailed evaluation which involves an overnight study at the hospital. Some men (18 years and older) may continue on to receive treatment with pulsatile GnRH. This treatment replaces the hormone which is absent in IHH and results in normalized testosterone and typically is effective in developing fertility.

NO INTERVENTIONSubjects undergo the baseline evaluation off treatment
GnRH Treatment
EXPERIMENTALSubjects receive long term pulsatile GnRH therapy
Interventions
pulsatile GnRH is delivered to adult men (18+ yrs) via portable microinfusion pump. A small dose (30 microliters) is delivered subcutaneously every 120 minutes. The initial dose is 25 ng/Kg which is increased until normal serum testosterone levels are achieved.
Eligibility Criteria
You may qualify if:
- adolescent boys (age 16-17 years) and adult male individuals (age 18 years and older) with a single serum sample demonstrating low testosterone in association with low or inappropriately normal gonadotropin levels
- adolescent girls (age 16-17 years) and adult female individuals (age 18 years and older) with a single serum sample demonstrating low estradiol (estrogen) in association with low or inappropriately normal gonadotropin levels
- suitable male and female hypogonadotropic hypogonadal subjects
