  1. sd= standard deviation, IQR- interquartile range, AMH= anti-mullerian hormone, BMI = body mass index, HOMA-IR= homeostatic model assessment of insulin resistance, OM/AM= oligomenorrhea/amenorrhea, FAI= free androgen index, PCOS= polycystic ovary syndrome
  2. 1– among entire sample based on AMH percentiles among those with normal FAI and regular menstrual cycles
