Brief Summary
The use of metformin pre-treatment and co-administration was recently proposed in infertile women affected by polycystic ovary syndrome (PCOS) treated with gonadotropins. Data from meta-analyses showed that metformin administration significantly reduced the stimulation length and the total dose of gonadotropins used in PCOS women undergoing gonadotropins stimulation for non in-vitro fertilization (IVF) cycles. On the other hand, in IVF cycles metformin was demonstrated to significantly reduce the ovarian hyperstimulation syndrome (OHSS) rate in infertile patients with PCOS treated with gonadotropins. The metformin regulating effect on the ovarian response was also observed in a randomized controlled trial (RCT) on young non-obese insulin-resistant women with PCOS receiving gonadotropins for mono-ovulation induction. In particular, metformin increased the mono-ovulatory cycles, the duration of stimulation and the amount of gonadotropins used, while it reduced the number of dominant follicles and the estradiol (E2) levels. The aim of the present study was to evaluate the effect of metformin administration in high responder PCOS patients undergoing gonadotropins ovarian stimulation for IVF cycles.
