Interesting surprises you never knew about sperm

What did you know about sperm? The following may help you understand more interesting things about sperm, about the existence and the way they work in maintaining the human race.

1. How many sperm cells are released when a man ejaculates? The number of spermatozoa varies from about 20 million to 100 million sperm per ml when ejaculating. Healthy men will produce from 1.5ml to 5ml of semen every ejaculation.

2. The size of this sperm cell is about 50µm (0.05mm). The smallest cells you can see with your eyes are only about 0.1mm. So to see the sperm needs a microscope.

3. Sperm is composed of small cells called homunculi or animalcules . Each sperm cell consists of three basic parts: the head (which contains genetic DNA), the middle part (energizing the tail), and its own tail (also known as the whip).

4. How fast can sperm swim? Sperm cells swim about 5mm a second, or about 0.2 inches. This speed may sound slow, but it is not small compared to the size of the sperm. If a whale is capable of moving quickly like sperm, then the whale can swim at 15,000 miles an hour.

5. How do sperms know the way? Scientists believe that sperm cells reach the egg in two complex mechanisms, including the ability to swim toward the higher concentration of the molecules produced by eggs (also known as chemotaxis) and the ability to target high temperature areas in a woman's reproductive gland to look to the uterus (also called thermotaxis).

6. The person who discovered sperm cells was Antonie van Leeuwenhoek (1632-1723). The Dutch amateur scientist observed sperm cells in 1677. Van Leeuwenhoek was also the first to observe bacteria, muscle fibers, and the flow of blood cells through capillaries. . He is called the "father of microorganisms".

7. How long can sperm cells survive? That depends on a field they exist. If inside a woman's reproductive organs, sperm can survive for up to five days. If in an external environment, sperm can only live for at most a few hours.

8. With sperm cells that are not ejaculated, they will be returned to the man's body.

Sperm shaped like tadpoles

9. Does the sperm count decrease with time? It is difficult to determine. Previously, a report that investigated sperm increase and decrease from 1938 to 1990 showed that sperm decreased from 113 million / ml to 66 million / ml. But recent researchers argue that sperm counts are stable.

10 . Sperm looks like tadpoles. However, more than 90% of sperm are produced with more or less deformities such as two heads, two tails, deformed heads or tail. These differences affect the ability to move and access eggs.

However, that does not mean that the man is infertile. Normal sperm have an oval head and long tail. In the race to race for eggs, millions of sperms failed, only a handful of healthy sperms could approach. And this is the natural selection.

Sperm needs 46-72 days to mature in the testes and is ready for fertilization

11. Although men continue to produce sperm and in 1 second can release thousands of sperms, but sperm needs few months to mature. On average, they need 46-72 days to mature in the testes and are ready for fertilization.

But gentlemen need not worry, even when ejaculating, a new sperm "batch" has been prepared for the next action.

12. A testicle can provide enough sperm. There are people who only have one of the two testicles active.

However, just that is enough for him to produce a powerful team of soldiers preparing for the process of conception. That means having an active testicle does not affect your ability to have children.

13. Even if your body can warm up under a warm blanket, sperm will remain cool. The testicles always maintain a temperature of about 7 degrees lower than their body temperature to ensure a healthy team of sperms.

14. Is external ejaculation an effective contraceptive method? External ejaculation method is performed when a man withdraws his penis from the woman's vagina before ejaculation. In fact contrary to many people, this method really does not achieve high effectiveness in contraception. Before ejaculation, a small amount of semen will escape the penis. Women are fully capable of becoming pregnant if this fluid is in contact with the vagina.

Pregnancy when having sex in a hot tub is rare and almost impossible.

15. How long can sperm live in a hot tub? In a hot tub, sperm cannot live long and will die within seconds. That's why pregnancy when you have sex in a hot tub is rare and almost impossible.

16. How long can sperm live when frozen? Scientists believe that sperm can survive for a long time if they are cooled at low temperatures, provided the temperature is maintained at a stable level. At low temperatures of around -196 ° C, sperm will return to the inactive form, meaning that all their functional activity is stopped.

17. How are sperm created? Normally, there are millions of sperm created every day in the testicles. During this time, the cells that make sperm are constantly dividing and changing.
