Abstract:
The term, women's health, was historically synonymous with reproductive health. When the prevailing thought among scientists and physicians was that women were just little men and reproductive organs were the only difference between the sexes, the Society for Women's Health Research (SWHR) was formed to change this conventional wisdom. SWHR realizes that austerity measures are necessary during hard economic times; however, we believe that sequestration is not the appropriate tool to reduce our federal deficit. Medical research, while vital to the scientific community, is also fundamental to the U.S. economy. Biomedical research and research on health statistics, surveillance data, and disease tracking are critical to maintaining a healthy society and are the difference between sickness and health for all women and their families.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
