Weight Loss Helps Obese Men Improve their Sperm Count

A recent study found that men who lost weight and maintained weight loss with a low-calorie diet improved their sperm count. In this study, 50 men with obesity ate a low-calorie diet for eight weeks and lost an average 36 pounds and improved their sperm count by about 40%.

Numerous studies have linked obesity to lower sperm quality and quantity, contributing to reduced fertility. Dr. Bobby Najari,  assistant professor and director of the Male Infertility Program at NYU Langone Health in New York City, believes that the hormonal effects of excess fat tissue reduces testosterone levels which in turn reduces sperm reduction. Najari said the new findings suggest that weight loss reverses this process.

"This provides hope that the negative impact [of obesity] on sperm quality isn't permanent and can be reversed through diet and exercise," said Dr. Najari.
