Progesterone production by granulosa cells from patients with different body mass indexes. Patients with normal body mass index [BMI] (18.5–24.9) had a significant increase in progesterone production when treated with hCG (P < 0.0001). Cells of patients who were categorized as overweight (BMI 25–29.9) or obese (BMI >30) did not have an increase in progesterone production when stimulated with hCG (P > 0.05). Asterisks indicate a difference of (P < 0.05) from control value with BMI categories. Cells were treated with PGF2α (0.1 μg/ml) or hCG (5 IU/ml). N values for each treatment group are given in parenthesis above each column
