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 3-fold increased risk of having a low count of progressively motile sperms, those that swim forward in a straight line.

1. Increased body fat can also contribute to lower testosterone levels and higher estrogen levels.
2. Obese men were also 1.6 times more likely than overweight or normal-weight men to have a high percentage of abnormally shaped sperm.
3. There is a trend toward increasing likelihood of erectile dysfunction with increasing BMI.
4. Obesity is associated with a greater risk of impotence.
5. Obesity is also associated with metabolic syndrome and polycystic ovarian disease (PCOD) in women and associated infertility.
