By Dr. BPS Tyagi Obese men are more than three times as likely to have low sperm
counts compared with their normal-weight peers. A study published in the journal Fertility and Sterility showed that the heaviest men were at triple the risk of having a low count of progressively motile sperms — sperms that swim forward in a straight line.
- Increased body fat can also contribute to lower testosterone
levels and higher estrogen levels.
- Obese men were also 1.6 times more likely than overweight or
normal-weight men to have a high percentage of abnormally shaped sperm.
- There is a trend toward increasing likelihood of erectile
dysfunction with increasing BMI.
- Obesity is associated with a greater risk of impotence.
- Obesity is also associated with metabolic syndrome and
polycystic ovarian disease (PCOD) in women and associated infertility.
