Sperm quality in men is not only determined by the condition of the reproductive system, but also influenced by bone health. If you want to have sperm quality, make sure the framework of the body is always maintained his health.

A study at Columbia University showed that the healthy bone to produce more osteocalcin, a protein that make up the bones and teeth. Protein content is what will affect the fertility of male reproductive system.

In that study, men whose bones are not many produce osteocalcin tend to be less potent difficult to fertilize their partner. Conversely, if osteocalcin produced in the bone more and more, the quality of male sperm would increase so that more potent.

When investigated further, osteocalcin was associated with the production of the male sex hormone testosterone. High levels of osteocalcin which trigger the production of more testosterone, so men are capable of producing higher quality sperm.

The findings are then followed up with an experiment on male rats. When male rats were injected ostgeocalcin, testosterone production increases, which produced more sperm quality, and certainly more potent to inseminate female mice.

"The relationship between bone health with the reproductive system were observed only in men. We did not find similar effects in women and female rats," said the researcher, as quoted by Gerard Karsenty of Sify.com, Monday (02/21/2011).

This finding is quite interesting because the relationship between the bone with the reproductive system previously only focused on the function of the gonad gland, the gland that regulates male and female genitalia. The higher activity of the gonad gland, the more bone cells produced by the body.

Most men would not worry if the sperm is too weak, because the viscosity including indicators of sperm quality. But the sperm is thick also not always good, because if too thick it will be difficult to fertilize the egg.

Semen quality characteristics have somewhat thicker because it contains protein. The nature of the protein is easy to clot (coagulation) when involved in contact with air, so the level of consistency can be measured by the length of sperm clumping.

Normally sperm will clot within 20-30 minutes if left in the open air. Sperm that is too thin it may take longer to clot and is usually triggered by the number of sperm cells that are too small or there is infection in the urinary tract.

Still does not mean that rapid semen clot is always more potent or fertile than the more dilute. Sperm are too quick to clot alias too thick it difficult for sperm cells to swim toward the egg to be fertilized.

Quoted from WebMD on Thursday (17/02/2011), semen viscosity is rarely the sole cause of infertility in men. That is, sperm that are too thick really is not that affect the quality of sperm in relation to the ability to fertilize an egg.

But in many cases, sperm that are too thick are closely related to other conditions that reduce male fertility, such as prostatitis or prostate tract infection. Thickness of sperm is often used by urology doctors to detect the infection.

In these circumstances, the quality of sperm produced will generally decline. Moreover, the liquid becomes more viscous sperm, sperm cells must be diluted and then manually injected into the egg through artificial insemination if you want to have kids.

The male sperm cell production dwindle over time, allegedly due to increased pollution that contaminate food and the environment. The impact not only reduce fertility, but also increase the risk of cancer in men.

Research conducted by experts from the University of Turku in Finland showed that the number of male sperm cells began to decrease since the late 1970s. Only in 10 years, the average number of sperm produced by men has decreased by about 30 percent.

Research conducted in Finland that note, the number of sperm produced by men born in 1979-1981 was about 227 million / ml. Men born in 1982-1983 to produce 202 million sperm / ml, while the above was born in 1983 produced only 165 million / ml.

Although only performed in Finland, the results of this study is believed to be an indicator of male fertility in the world. The reason for this Finnish man considered the most 'manly' in terms of fertility, since sperm production average more than any other man in the world.

Besides observing that fewer sperm production, researchers also saw the risk of cancer in men who tended to increase. Compared to the group of men born in the era of the 1950s, testicular cancer is more common in men who were born after the 1980's.
