Objective: To study the relationship between obesity and serum and ultrasound markers of ovarian reserve in premenopausal women.

Methods: We performed a cross-sectional comparative study of two age-matched groups of premenopausal participants (early transition phase): 50 participants ("non-obese") had a BMI < 30 kg/m2, and the other 50 participants ("obese") had a BMI of 30 to 35 kg/m2. The obese women had a mean age of 46.
