Both obese men and women can face fertility problems unless they reduce their weight. Reducing weight as the first step can bring back their fertility.
• 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.
