BEING overweight reduces men鈥檚 fertility, says William Roudebush of Reproductive Biology Associates in Atlanta, Georgia.
The more sperm with fragmented DNA a man has, the lower the chances of conception and the higher the chances of miscarriage. Roudebush鈥檚 team looked for a link between fragmented DNA in sperm and obesity, as measured by body mass index. 鈥淎s BMI goes up, the DNA fragmentation rate goes up, and we could see a dramatic reduction of sperm quality,鈥� Roudebush told a meeting of the American Society for Reproductive Medicine in San Antonio, Texas, last week.
He speculates that obesity is partly to blame for the decline in male fertility in the west.
