Summary The aim of this study was to investigate the relations of basic semen parameters and reproductive hormones with alanine aminotransferase (ALT) and gamma‐glutamyl transferase (GGT). In addition, to examine possible interaction between adiposity, alcohol consumption, and liver tests in relation to male reproductive health, standard semen analysis was performed and serum levels of reproductive hormones and liver tests were measured in 245 male partners of pregnant women at a University Hospital Andrology Centres in Estonia. Quartile analysis revealed that after adjustment for covariates GGT was negatively related to sperm concentration and total sperm count. These significant changes appeared from a GGT >35.5 U/L. Next to these changes ALT was not related to sperm parameters. Both enzymes, GGT and ALT, were not related to reproductive hormones. Alcohol consumption was positively related to GGT and in cases with elevated GGT alcohol use was negatively related to sperm concentration and total sperm count. Alcohol consumption was positively related to body mass index (BMI) and waist circumference (WC). Our findings also confirm results of previous studies that BMI and WC are associated positively with ALT and GGT. According to the study, increased GGT activity might represent a possible connection between adiposity, alcohol consumption, and semen quality.
