After decades of attempts, the researchers were able create fertile sperm in a laboratory and design that increase hope for infertile men.
"I think for everyone in this field, especially for potential patients, it is quite exciting, "says Martyn Dym, professor and biochemist at the Faculty of Medicine at Georgetown University.
Japanese scientists generated mouse sperm in a dish, which already been done before. However, in the past manufactured sperm had failed to achieve pregnancy in a female mouse. This time, when the sperm was injected into the eggs, the female had a dozen live mice.
"The proof is in the dessert, "says Dym." They were able to have babies. "
" Bravo, "says Pamela Madsen, founder of the American Association Fertility. "This is a breakthrough for men who do not produce sperm, such as those with Klinefelter syndrome, or those who have had testicular cancer."
However, Madsen notes that many of infertile men do not need artificial sperm, as they have some healthy functioning properly.
"In the world of infertility that would really be exciting to do this for the eggs," says Masden. The researchers created
is sperm to remove tissue from the testes of mice, which contain stem cells.
The trick to ensure that the sperm were capable of achieving pregnancy a female was to find the right medium for the growth of stem cells.
not yet know when you start the creation of human sperm in the laboratory, in the past many treatments that worked in mice have failed in humans. CNNEXPANSIÓN
