FEM Differences Study | Female Estrogen Metabolism (FEM) Differences Study

Women have variable amounts of estrogen produced from the growing follicles that circulates in their blood as they undergo ovarian stimulation. Higher studies suggest this difference may be related to how women metabolize estrogen. This matters because it effects how much hormone goes in circulation and may have implications on how effective medications are, as well as how many medication side effects women feel. Our goal will be to determine, if metabolize difference are present, and if so, to learn why these differences ocur. 

You may be eligible if you are: Female, 18 years or older, and undergoing ovarian stimulation for elective oocyte cryopreservation or in vitro fertilization.
