Clinical Trial Summary

The goal of this study is to learn about the role of kisspeptin in the reproductive system. Kisspeptin is a naturally occurring hormone in humans that causes the release of other hormones, including gonadotropin-releasing hormone (GnRH) in the body.

Description:

The reproductive hormone GnRH is essential for normal reproductive function. People with idiopathic hypogonadotropic hypogonadism (IHH), hyperprolactinemia, and polycystic ovarian syndrome (PCOS) do not secrete or respond to GnRH in a normal way. In this study, investigators will give participants kisspeptin-a hormone that is naturally found in the human body and is known to be a powerful stimulus of GnRH secretion. They may also give participants GnRH to determine if participants will be able to fully respond to kisspeptin. The goal of this study is to use kisspeptin administration to probe the condition of GnRH neurons in people with various reproductive disorders to better understand the underlying reasons for the disorders. Investigators hope to gain new insights into GnRH neuronal function (or dysfunction) that will lead to better diagnostics in the future.

All subjects with reproductive disorders will meet the following criteria:

• 18 years or older,
• all medical conditions stable and well controlled,
• no prescription medications known to affect reproductive endocrine function for at least 2 months except for medications used to treat the subject's reproductive condition,
• no history of a medication reaction requiring emergency medical care,
• no illicit drug use or excessive alcohol consumption (<10 drinks/week),
• for women, not breastfeeding or pregnant,
• if applicable, able to undergo appropriate washout from hormone therapy,
• normal physical exam and laboratory studies within protocol reference ranges,
• for women, at time of screening negative hCG pregnancy test.

Additional criteria based on subject population:

1. Men and women with hypogonadotropic hypogonadism,

• Confirmed diagnosis by low sex steroids in the setting of low or inappropriately normal gonadotropins,
• If needed, additional labs and imaging tests may be performed.

2. Women with Polycystic Ovarian Syndrome (PCOS)

• Confirmed diagnosis of PCOS,
• If needed, additional labs and imaging tests may be performed.

3. Men and women with hyperprolactinemia

• confirmed diagnosis of elevated levels of prolactin measured via blood test,
• no pituitary adenoma OR a microprolactinoma (<10 mm). Patients with a macroprolactinoma confirmed on MRI imaging will be excluded,
• willing to complete a dopamine agonist washout.
