Watch your weight
“The healthier the body, the healthier the sperm,” says Jamin Brahmbhatt, MD, co-director of the PUR Clinic in Clermont, Florida. A study by Harvard School of Public Health found that overweight men were 11 percent more likely to have a low sperm count and 39 percent more likely to have no sperm at all in their ejaculate than normal-weight men. The news was even worse for men who were obese; they were 42 percent more likely to have a low sperm count and 81 percent more likely to produce no sperm than men at a normal weight. These are surprising facts about fertility OB-GYNs wish you knew.
Ditch the cigarettes
Smoking doesn’t just affect your lungs, it can also impact your fertility. “Smoking is known to affect our sperm count, motion, and general health of sperm. Tobacco metabolites can even be found in semen,” says Edmund Sabanegh, MD, director of the Center for Male Fertility at Cleveland Clinic in Cleveland, Ohio. The good news: Sperm health seems to bounce back relatively quickly once men quit.
