- Active fitness impede fertility
- Stem cells to help in transplantation
- May the least favorable for conception
- In the United States lifted a ban on the state support of research embryos
As shown by the disappointing data of Russian statistics, the problem
infertility
As for more than 15% of the population, or 4 to 2 million. couples of reproductive age. For this reason, each 8 family in Russia has no children. Data World Health Organization also can not please: their information worldwide about 70 million. People can not have children because of certain circumstances.
The reasons for which a person can not have children there is a whole lot from birth defects to the impact of the environment and the lack of hormones.
Among the diseases that cause male infertility, the most frequent are:
- Diabetes
- Erectile dysfunction
- Varicocele
- Parotitis
Biotechnology from the Japanese city of Kyoto could from Embryonic stem cells recreate sperm . However, at the moment, such experiments were carried out only on biological material of mice. First, stem cells, scientists were able to obtain gonocytes That is, primary germ cell. They were transplanted into mice suffering from infertility in the reproductive system which they developed into full-fledged sperm.
The thus obtained spermatozoa were used to fertilize the female and administered. As a result, we were born healthy pups who subsequently be able to give full-fledged offspring. According to scientists, and you can get gonocytes of adult stem cells of the skin.
Such experiments on mice appear to be very encouraging professionals: in their view, in the near future it will be possible to talk about the possibility of the same procedure to human cells.
