Jakarta, Sunlight is known to contain vitamin D is good for the bones. But for men, the sun can provide additional benefits to improve the quality of sperm.
A study involving about 340 men found that vitamin D is produced by the body when exposed to sunlight can improve sperm quality. This condition is good for men who want to be an expectant father.
Researchers from the University of Copenhagen tested the quality of the sperm of 340 men chosen at random and perform a detailed analysis of these samples in the laboratory, researchers also measured the amount of vitamin D in their blood.
The study shows men with adequate levels of vitamin D in the body will have a better sperm when swimming toward the egg, as well as greater speed and more penetrative.
If men are deficient in vitamin D in the blood of healthy sperm counts will tend to be lower compared with men who have normal levels of vitamin D, the ability to fertilize an egg cell (acrosome reaction) is inhibited and the body's ability to absorb calcium also is inhibited .
Sunlight is the main source of vitamin D which helps regulate levels of calcium and phosphorous to generate healthy bones. Most of the experts recommended amount of vitamin D in the blood is at 75 nmol / l.
"The level of vitamin D in the blood are positively correlated with sperm motility, suggesting a role of vitamin D in human sperm function," says Dr. Martin Blomberg Jensen, as quoted from Dailymail, Monday (05/23/2011).
The findings were published in the journal Human Reproduction that supports previous research on the relationship of vitamin D to sperm production. These results also may explain why many couples who need a vacation to get pregnant fast.
