Determinants of testosterone recovery after bariatric surgery is it only a matter of reduction of body mass index

Friday, May 31, 2013
Body mass index correlation with sex hormones is exponential for testosterone and power for sex hormone–binding globulin (SHBG). Bariatric surgery improves all parameters with a higher than expected (for corresponding weight loss) increase of total testosterone and SHBG.
