Purpose
The investigators are seeking subjects for a study of the role of kisspeptin in the reproductive system. Kisspeptin is a naturally occuring hormone in humans that stimulates the production of reproductive hormones. The investigators hypothesize that kisspeptin administration will be a useful tool for characterizing certain reproductive disorders.
The investigators are seeking men and women with idiopathic hypogonadotropic hypogonadism (IHH). Study participation involves 1-2 outpatient visits and 1-2 12-14-hour hospital admission(s) when subjects will receive kisspeptin and/or gonadotropin-releasing hormone (GnRH). Remuneration is up to $900 for study completion. Individuals interested in learning more may call 617-724-8592.

Detailed Description:
The master reproductive hormone GnRH (gonadotropin-releasing hormone) is essential for normal reproductive function. Individuals who fail to secrete or respond to GnRH have a condition called hypogonadotropic hypogonadism. These individuals fail to undergo puberty and are infertile. Study of these patients has led to better understanding of the reproductive endocrine system.
Kisspeptin is a peptide hormone that has recently been found to be a potent stimulus for GnRH release. This hormone has several potential applications:
- in research settings, administration of kisspeptin may be used to characterize the precise defect in subjects with hypogonadotropic hypogonadism and, in turn, may lead to better understanding of the reproductive endocrine system
- kisspeptin may have diagnostic applications in the evaluation of delayed puberty and infertility
- kisspeptin may have applications in the treatment of reproductive disorders such as infertility and irregular or absent menstrual periods
This study is to assess the effects of kisspeptin administered in subjects with hypogonadotropic hypogonadism.
