May cause low sperm: He should do a semen analysis first - could be normal. Overweight/ obese men often have low sperm count or low sperm quality. Fat tissue converts testosterone (male hormone) into estrogen (female hormone). If his sperm is abnormal get hormone tests including testosterone and estrogen levels, if t is low and e is high tablets called aromatase inhibitors may help. Exercise & weight loss also helpful.
