s*x is about as much fun as two people can have. This is a well-documented fact. But when it comes to sperm, are you all up on your swimmers-knowledge? There’s a lot to know about those little guys. Here are just ten of the many wild facts you should know about sperm.
1. Not all sperm are made equal: As much as a man would love to have millions of perfect little guys, the fact is that many of them are deformed. We’re talking two heads, two tails, squiggly tails, heads that are too large or two small, etc.
2. Sperm are hard workers: Well, not all of them. But of the ones that can swim straight enough to get to the egg, one lucky bugger (though sometimes more than one. Can you say multiples?) drills its way into the egg to begin fertilization.
3. There is a difference between “sperm” and “semen”: Many people use both terms interchangeably, but they are not the same substance. Sperm cells are just one part of the semen. Seminal fluid also contains fructose and proteolytic, among other enzymes, to help the sperm on they way.
4. The odds are tough: In the average release, there are 200 million sperm. That’s some steep competition!
5. Sperms don’t have to be moving to fertilize an egg: That’s both true and not true. For natural fertilization to occur, the sperm has to be able to swim and drill into the egg, but during In-Vitro fertilization, the sperm is injected directly into the egg, making motion on the sperm’s part a non-issue.
6. They don’t always know where they’re going: Only about half of the sperm who are ejaculated make it to the egg. The rest doodle around in circles.
7. You need to keep your boys cool: For healthy sperm to exist in a man’s body, the testicles need to be cooler than the body. On average, testicles are seven degrees cooler than the rest of the body. You don’t want the testicles to be any closer to the warmth than necessary. That’s why boxers are better than briefs when it comes to making babies!
