Understanding Experimentally Induced Hot Flushes
The purpose of the study is to examine the impact of hot flushes on sleep, mood, and well-being. Hot flushes (or "hot flashes") are a feeling of being overheated, and often are followed by heavy sweating, skin becoming red and hot, and discomfort. Sometimes hot flushes are followed by chills. Some women experience a rapid heart rate. Hot flushes that happen at night are called night sweats, and they may interfere with sleep.
The investigators will cause hot flushes by giving study participants a hormone medication called leuprolide (Lupron). Hormones are chemicals that are naturally produced in the body. Leuprolide is a manufactured (artificial) hormone that will make the body think that it has reached menopause temporarily. Most women begin to have hot flushes within 4 weeks after taking leuprolide.
The investigators will also evaluate changes in sleep, mood, and feelings of well-being over the course of the study. The investigators will use questionnaires to measure these changes.

- To examine the impact of hot flushes on sleep, mood, and well-being. [ Time Frame: Baseline and post-treatment (4 weeks after GnRH agonist) ] [ Designated as safety issue: No ]Experimentally induced hot flushes will correlate with impairment of sleep and mood.
- To describe the hormonal dynamics after administration of a gonadotropin-releasing hormone agonist that are associated with the development of hot flushes. [ Time Frame: Baseline and post-treatment (4 weeks after GnRH agonist) ] [ Designated as safety issue: No ]Changes in reproductive hormones after administration of a gonadotropin-releasing hormone will differ between those who do and do not develop hot flushes.

Leuprolide is a widely used GnRH agonist that is manufactured by TAP Pharmaceutical Products. Leuprolide is indicated for treatment of endometriosis, uterine fibroids, precocious puberty, and prostate cancer, and is used off-label for in-vitro fertilization and premenstrual syndrome. In this protocol, leuprolide will be administered once during the mid-luteal phase of the menstrual cycle at a dose routinely used for treatment of endometriosis and uterine fibroids in women.
