Table 1 Criteria to establish the starting daily dose of rFSH according to age, body mass index (BMI), basal FSH, and AFC

From: Ovarian sensitivity index is strongly related to circulating AMH and may be used to predict ovarian response to exogenous gonadotropins in IVF

Clinical characteristics

rFSH starting dose (IU)

Age < 35 + normal BMI + basal FSH < 8 IU/L + AFC > 14

100 - 150

Age < 35 + BMI 25-30 + basal FSH < 8 IU/L + AFC > 14

200

Age 35-40 and/or basal FSH 8-10 IU/L and/or AFC 8-13

150 - 250

Age 35-40 and/or basal FSH 8-10 IU/L and/or AFC 8-13, BMI > 25

300

  1. Patients above 40 years, with BMI > 30 or < 19, basal FSH levels > 10 IU/L and/or AFC < 8 were a priori excluded from the study.
