Detect concussions: Zika virus causing testicular atrophy by 90%
The US health experts warned Zika virus can cause testicular atrophy 90% of men, leading to infertility.
Zika virus so far been known early may lead to small babies. And the scientists had a new discovery shows the impact of this virus dangerous to men.
Professor Michael Diamond and several colleagues at Washington University School of Medicine (USA) has conducted impact studies of Zika virus in mice and concluded: this virus has the ability to shrink testicles and cause 90% of infertility in this rodent species.
Although no precise conclusions about symptoms caused atrophy 90% testes in humans but the team believes that at least Zika virus can reduce sperm count and testosterone levels in men are affected.
Professor Diamond said: "We experimented on rats should not Zika know whether similar effects in men or not. However, experiments show that the men may face low testosterone levels and sperm counts decreased after exposure to Zika, do not exclude the possibility that lead to infertility ".
Earlier, it was discovered virus Zika live in semen up to several months but it is unclear what specific impact on a man's disease.
the research group of professor Diamond published in the journal Nature Genetics. After two weeks of testing, the testes of mice were infected Zika significant atrophy. Multiple cells (mostly capital Sertoli cells can not reproduce) destroyed or just "barely alive".
After 3 weeks, their testicles shriveled 1/10 compared to its original size. Even after 6 weeks when the team remove the virus from the body rats, their testicles are still unable to recover.
According to Professor Diamond, Zika virus infected male mice with fertility for a little female mice 4 times more than normal, while the number of sperm decreased by 10 times and very low testosterone levels.
Co-author Kelle Moley fears: "This is my only viruses known to cause severe symptoms importance such as infertility. There are very few bacteria can pass testis barrier to blood flow in the body to affect and infect the testicles directly. "
Dr. Peter Barlow from Edinburgh Napier University, noted:" In when we are not clear Zika virus have reduced testes size and fertility in men or not, this study caused concerns Zika virus is capable of a direct impact on fertility in men increased . Thus, the imperative now is to continue to monitor the mice in the lab to confirm that they have an impact on men or not. "
