1 GET PHYSICAL BEFORE ERM, GETTING PHYSICAL
Researchers from Harvard found that men who worked out 15 hours or more a week had a sperm concentration that was 73 percent higher than guys who didn’t work out at all. Yikes. Other factors that can affect your man’s number of swimmers? Smoking, varicose veins, and obesity.2 TOUGH ODDS
It only takes a single sperm to fertilise a woman’s egg, but the average ejaculation – roughly one teaspoon – contains about 200 million swimmers. That’s what we call stiff competition.
3 THE PARTY DON’T STOP
Women may be born with all the eggs that they’ll ever have, but men keep producing sperm all day, every day. Yep, that is one mean, sperm making machine. It takes about two months for a sperm cell to go from start to finish.
4 SPERM VS SEMEN
You may use sperm and semen interchangeably, but they’re actually not one and the same. Sperm is just a small component of semen, which is also made up of proteins, Vitamin C, zinc and more. Just think of sperm as the tadpoles and semen as the river. Erm, or maybe don’t think of it that way.
5 SPERM GET LOST, TOO
Only about half the sperm who are ejaculated actually make it to the finish line – the rest just swim around in circles, refusing to ask for directions we assume.
6 NO, HOT TUBS DON’T PREVENT PREGNANCY
But heat – including “wet heat” – isn’t good for sperm. Human testes need to stay cooler than the rest of the body to function – don’t worry, the male anatomy is naturally designed this way (isn’t Mother Nature amazing?). But if the temperature of your testes goes up from some outside source (say by sitting in a hot car seat) then this could, well, fry your sperm.
