Secret decoding of the

In every second, the man's genitalia can 'produce' 1,500 sperm. Along with these amazing "unlockers" scientists and many other secrets of sperms.

For more than 40 years, scientists have suggested that stem cells in the testes, or sperm cells (germline), become sperm in just two simple steps. However, the latest practical studies on mice (with interaction with the human body) negate this view and conclude that new sperm cells can grow into sperm. by many different paths.

"There is no linear development from sperm cells to become sperm ," said researcher Robert Braun, deputy director of Jackson lab in Bar Harbor, Maine, USA. Add: 'Sometimes the sperm cells undergo some division to become sperm and sometimes not'.

Moreover, the researchers also found that some sperm cells, when they have made half the way to becoming sperm, can 'turn' back to their old state (flow cells). fine). This was originally considered impossible.

In the new study, the scientists let the mouse sperm cells appear under fluorescent light to observe the development of this cell. In addition, the scientists also labeled the mouse's fine line cells with certain colors and observed their variation over time. New studies also show that sperm is grown from a smaller part of the stem cell line in the testicle.

The life cycle of sperm is very short. Therefore, it must always be supplemented and replaced. In addition, the long journey to reach the final responsibility is to combine with a woman's egg, which is one of the reasons why sperm must reach 1,500 per second.

However, to be able to continuously produce a 'stream' of sperm from puberty to old age requires the body of a man to maintain a balance of flow cell development. sperm into sperm is very stable.

If the sperm cell line for a long time does not develop to become sperm, the man may be at risk for testicular cancer. But if the stem cell lines that grow too often into sperm, the man can get infertility.

Unlocking the mystery of sperm development will help a lot in studying male infertility treatments. "Understanding and understanding the normal behavior of cells, we will know how to regulate their development," Mr. Braun said .
