A new study shows that Zika targets the male reproductive system, at least in mice. Three weeks after Zika infection, male mice had shrunken testicles, low levels of sex hormones and reduced fertility, and their sperm remained infected with the virus, as shown above. The results suggest that Zika infection may interfere with men’s ability to have children, but additional studies are needed.
