Why Manly Men are More Susceptible to the Flu
Why Testosterone Hinders the Flu Shot
Researchers founds that testosterone -- the hormone that fuels men’s sex drive, beard growth and muscle development -- causes genes in the immune system to produce fewer antibodies in response to the flu shot. And the higher testosterone a guy has, the lower his antibodies (and immune protection) are. That makes the vaccine less effective, thus increasing a guy’s chance of coming down with the flu.
And it gets worse, fellas: It’s known that men also don’t respond as well as women to several other vaccines, such as hepatitis and measles, and their overall weaker immune systems make them more susceptible to all types of infections.
How to Stay Flu-Free
Experts are divided about what the findings mean for your annual flu shot. It’s possible that men could receive a higher dosage in the future. To make sure you beat the flu this season, don’t skip the shot—it’s still your best defense—and follow these stay-healthy tips:
  • Practice proper hygiene. Make sure you wash your hands frequently with soap and water (or hand sanitizer if you can’t get to a sink). Keep your hands away from your eyes, mouth and nose, and steer clear of anyone who’s sick. Take this quiz and learn how to germ-proof your life.
  • Hit the hay. Research has shown that not getting enough sleep impairs your immune system’s ability to fight disease. What’s stealing your sleep?
