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.
