Role of Gonadotropin Pulsations in the Reversal of Hypogonadotropic Hypogonadism

Massachusetts General Hospital·interventional·Posted Oct 26, 2006·Updated Jul 11, 2022

In Brief

A Phase 1 clinical trial evaluating gonadotropin releasing hormone (GnRH) for Kallmann Syndrome and 2 related conditions. Completed, enrolled 624 participants across 1 site.

Detailed 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.

Interventions

gonadotropin releasing hormone (GnRH)drug

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.
