Sperm DNA Already Million Years

Genes on the man who is responsible for sperm production was already older than 600 million years. In addition, this gene was the same in all living creatures, from insects to mammals.

Gene called Boule still has the same function and has not changed one bit despite having passed the various evolution. Research on sperm genes was conducted by a team of experts from Northwestern University Feinberg School of Medicine. They compared the sperm derived from fruit flies, sea urchins, rooster, fish, and humans. When the gene Boule is removed from male rats, although the animals remained apparently healthy but do not produce sperm.

The results of this research has great benefits in human health, such as improving the understanding of fertility in men and can be developed to produce a contraceptive method for men.

"The results of this study proves that the body's ability to produce sperm very ancient, may still be the same as at the beginning of the evolution of the 600 million years ago," said Eugene Xu, a researcher in the field of obstetrics and gynecology.

He added, gene Boule is the oldest sperm-producing genes in humans has ever been found. The discovery that the genes exist in humans is similar to other living beings is very surprising the experts because sperm production is influenced by natural selection.
