Which of the following hormone level is evaluated for testing ovarian reserve?

Tests used to detect ovarian reserve are basal FSH, basal estradiol and inhibin B levels. Basal FSH is an impoant predictor of ovarian reserve and patients with levels greater than 20 mIU/ml are poor responders to ovulation induction. Basal estradiol levels greater than 50pg/ml also predicts poor ovarian reserve. Inhibin B is a glycoprotein secreted by granulosa cells of the ovary, with declining ovarian function the granulosa cell activity declines and inhibin levels will fall.
