10 Interesting Facts About Sperm to Men Do Not Know

Almost everyone, including men, only knows that sperm contributes to conception to help people maintain their race without knowing that there are many interesting things about these tiny "warriors". This article explains the key facts and context behind sperm.

• The process of sperm formation and the 5 facts startle you.
• For the healthiest sperm, men go to sleep at this "golden time".

1. Nearly 90% of sperm are unusually shaped.

Not all sperm are born alike. The fact is that up to 90% of sperm are abnormal deformed: there are two heads, two tails, deformed heads, scrawny tails.

2. Sperm are tireless "swimmers"

Not all sperm are hardworking, but most of them "swim" tirelessly. Although the "path" to the egg is quite far away, the sperm still swim in a continuous circuit to reach the egg. They swim at about 5mm / s, a remarkable speed compared to the tiny size of sperm, about 0.05mm. If a whale can reach sperm movement speed, they can swim at 15,000 miles per hour.

The end of the "contest" will have one or two lucky "athletes" penetrate the egg and the fertilization process begins.

3. "Sperm" and "semen" are not one.

Sperm and sperm are not the same things that many people think. In fact, sperm cells are only part of semen. Semen is a mixture of fructose (a type of sugar) and proteolytic (decomposing enzyme group), along with other enzymes, to complement the sperm's journey.

4. How many sperm cells are released when a man ejaculates?

The number of sperm in each male is different, but usually in the range of 20 million to 100 million sperm in each ml when ejaculating. A healthy male ejaculate averages about 200 million sperm at a time.

5. Not all sperm always know the way to the egg.

Only about half of the sperms have gone straight to the egg. The rest are "lost" and swim around.

6. The soldiers are very cold.

13 degrees Celsius is the best temperature for sperm to grow healthy in a man's body. Therefore, testicles always have lower temperatures than other parts of the body.

7. The life time of a sperm cell.

Unlike women born who have been assigned how many eggs are in the body, men continually produce new sperm. The "life expectancy" of a sperm cell from birth to death is about 2 months.

Sperm can survive for about 5 days in a woman's reproductive tract and only a few hours in the external environment.

8. Sperm also has sex

Sperm also has a male resemblance to the Y chromosome and the female-like chromosome X. According to the researchers, the Y chromosome is weaker but faster than the X chromosome, so the battle between sperms the opposite sex is very fierce.

9. Dead sperm can still create a healthy fetus.

During in vitro fertilization, dead sperm can still fertilize and form a fetus. But they can die again during processing, transplanting it.

10. 1 testicle can also provide enough sperm.

In fact, there are gentlemen who have only one active testicle and still produce enough sperm to conceive. It means that just having an active testicle does not affect a man's fertility.
