Female obesity is associated with subfertility, and sometimes with low serum ghrelin (Ghr) levels. Two recent clinical studies reported a negative correlation between Ghr and embryo viability or cleavage in women undergoing assisted reproduction treatments (ART). In this study we investigated, in women undergoing ICSI (intracitoplasmatic sperm injection), the possible association between serum Ghr, body mass index (BMI), other reproductive hormones and the ART success.The study included 75 women (from July 2014 to March 2015) that attended our fertility clinic (CIGOR). They were up to 39 years old, without polichistic ovarian syndrome and their male partners did not show severe male infertility. Thirty patients were normal weighted, 29 were overweighted (OW) and 16 were obese (OB) (according to their body mass index (BMI)). Neither women age nor years of sterility vary between groups, and were 34.5±0.4 and 3.6±0.3 respectively. Serum Ghr was significantly higher in OB than OW (2559.7±297.9 vs 1695.3±182.4 pg/ml, p
