A total of 46 women will be studied. We will study 23 obese and 23 non-obese women. There will be no BMI restriction. Twenty-three women will be randomly assigned to receive DCI (experimental group) and 23 women to receive placebo (control group). The women will be studied during the equivalent of the follicular phase of the cycle, as documented by a serum progesterone concentration of 2 ng/ml.
