So, by this point you know two important steps to improving your fertility: If you're obese, lose weight; if you're underweight, gain it. But, obviously, that's not all. If weight were the only factor influencing a couple's ability to conceive, the world would have fewer fertility clinics and lots more babies.
Fortunately, there are other things you can do to increase your chances of getting pregnant. In addition to weight management, both men and women should:
- Improve nutrition
- Manage stress
- Quit smoking
- Cut back on alcohol and caffeine
- Reduce exposure to environmental toxins
- Get regular checkups
In addition,women should avoid vigorous physical activity when trying to get pregnant. Going overboard with exercise can reduce progesterone production and interfere with ovulation [source: Mayo Clinic]. To a lesser degree, excessive exercise can impact a man's fertility by reducing testosterone levels [source: Levine]. Of course, moderate physical exercise is allowed for both sexes -- even recommended.
While men should follow the same general guidelines as women, there are a few differences to keep in mind. For example, abstaining from sex for more than a few days can affect a man's sperm quality. And certain male-specific health conditions, like low testosterone and variococeles (varicose veins in the testicles), should be addressed by a doctor so that they don't interfere with conception. As for the boxers vs. briefs debate: There's no scientific answer to that question, but educated guesses land on the side of boxers [source: Levine].
