Abstract

In order to study the effect of obesity or underweight on gonadotropins and steroid hormone levels, serum concentrations of FSH, LH.Testosterone, Estradiol, Estrone, 17-OH-Progesterone and SHBG were measured by RIA in obese, underweight and control women, all menstruating in the follicular phase.Serum concentrations of all parameters measured did not differ significantly in the underweight and control groups.All obese women had higher levels of estrone than the control group, and only obese patients with a body mass index above 39 showed a lower SHBG level than that of the control group.The data suggest that the increased levels of estrone could play a role in the amenorrhea of obese women.
