Abstract

Does increased body mass index (BMI) without an underlying metabolic issue negatively influence semen quality? Proof of concept we conducted retrospective data analysis of men (N = 84) undergoing assisted reproductive technology, who had liver function testing with fasted glucose concentrations and corresponding hormone profile (testosterone, LH, FSH and prolactin) and semen analysis. Sperm count and total concentration were only reduced in metabolically unhealthy overweight/obese men. Serum GTT was the biggest predictor of Normozoospermia and Oligospermia, with BMI having no effect. Increased BMI without an underlying metabolic condition (in particular signs of NAFLD) has no influence on semen quality.
