The purpose of the study is to understand how the ovarian follicle (the fluid filled structure in the ovary that contains the egg) makes estrogen and other hormones during normal aging, in women with different ethnic backgrounds, and in Fragile X premutation carriers. During reproductive aging, estradiol levels are increased, a phenomenon that may be related to increased aromatase activity. The investigators' own preliminary data suggest that estradiol is increased in African-American women compared to Caucasian women, which may also be related to aromatase activity. In addition, the investigators have examined female fragile X premutation carriers who still have regular menstrual cycles and have demonstrated evidence of early ovarian aging compared to age-matched controls. \*\*WE ARE RECRUITING ONLY WOMEN WITH FRAGILE-X PREMUTATION\*\*
