Metformin in Patients With PCOS and Predictors of Poor Ovarian Response Ongoing In-vitro Fertilization
Overview[ - collapse ][ - ]
Purpose | Metformin should be administered with caution and could be potentially dangerous in infertile patients with PCOS who show a poor ovarian response and are undergoing gonadotropin-based ovarian stimulation. However, data that address this point are totally lacking. On the basis of these considerations, the aim of the current clinical trial was to test the hypothesis that metformin reduces the ovarian response in infertile patients with PCOS who have a potentially poor ovarian response and who undergo gonadotropin stimulation for IVF cycles. |

Detailed Description | Primary infertile patients with PCOS older than 35 years and/or with a basal follicle-stimulating hormone (FSH) level higher than 10 IU/L who were scheduled for IVF cycles were enrolled in the study protocol. |
