6 weird and interesting facts about 'sperm'

Each time 'sublimation' , men can produce up to 200 million sperm cells. However there are many interesting things about these 'tiny swimming tadpoles' that you may not know.

>>>The strange swimming style of sperm

1. Possessing a strange appearance

The characteristic of a healthy sperm is to have a well-proportioned oval head and a long tail with 'hooves'. In other words, they mostly don't 'eat'. Only a third of a man's soldiers have a 'normal' appearance, most of them look weird and funny, Dr. Craig Niederberger revealed on Male Health.

Sperm defects can occur in one of the three main parts: head, neck or tail, or in many parts at the same time. For example, a faulty sperm can possess up to two ends, the head is too small or too big, the neck is bent or too thin, a tail is curved, broken or curly, or has many tails. However, whether these anomalies affect the power of the sperm is still a subject of controversy among scientists, Dr. Niederberger, who is currently the Dean of the University of Illinois Urology Department, Chicago. said.

2. New animal champion on 'bizarre'

Male beetle sperm can go into pairs, groups or even hooks
connected into a long thread consisting of hundreds or even thousands of sperms.

The sperm of the person who might be able to look pretty weird, but the champion of surreality must belong to animals. Instead of moving alone, the male beetle's sperm always goes into pairs, groups or even hooks together into a chain consisting of hundreds or thousands of 'swimmers'. This strange teamwork method can be traced back to the fact that the beetle sperm must adapt to the increasingly complex, evolutionary genital system of female beetles. 'When you look at the genital diagram of female beetles, you can't help but think that sperm needs a compass to find the way,' said biologist Scott Pitnick of Syracuse New York University. 'They are extremely complicated'.

Then there were the naked mole rat with sperm that looked as strange as their shape. The researchers found that most of the hairless men of the mouse did not swim (only 0.1% could swim). But these males still make the female conceive.

3. Discovered by the Dutch

It was not until 1677 that sperm was discovered when Dutch microscope maker Antony van Leeuwenhoek announced seeing 'animal microbes (animalcules) moving like eels in his own semen sample. under a microscope ".

'Their bodies are round but imprisoned at the head and close behind, eventually a long, thin tail,' Leeuwenhoek described.

4. Being misunderstood for a long time

Since before 1600, it was believed
The sperm head already contains the tiny figure.

Antony was the first person to discover sperm but was extremely confused when speculating on how sperm is fertilized for eggs. In fact, it was not until 1879 that people proved the existence of conception. In the 1600s, scholars believed that humans had formed in the egg or sperm, with tiny sizes to fit in.

Some 'sperms' even claim to have seen tiny figures in the head of sperm. They claim that women only do each job simply by providing 'incubator' for the male seed.

5. They are helped

Sperm is a small but powerful swimmer. Moreover, they are also assisted when they have to penetrate eggs. A hormone progesterone produced by a female body encourages sperm to thrust their tail more strongly so that they can penetrate an egg barrier. Another protein called catsper in sperm will be responsible for hormone signal reception, a study published in 2011 in the journal Nature reveals.

6. Masculine men are unlikely to possess strong sperm

Women are often attracted to men with deep, masculine voices. But a study published last December found that masculine men had absolutely no higher sperm quality than "high-pitched" gentlemen. In fact, sperm density in these people is even lower.
