“Zika virus remained in mouse testes after the infection had cleared from the blood, causing testicular tissue to atrophy and potentially affecting fertility, according to a study in mice published in Science Advances. The finding may explain why Zika virus appears to be sexually transmissible. Although the findings have yet to be replicated in humans, a US Centers for Disease Control and Prevention (CDC) team is conducting a similar study in Zika-infected men in Puerto Rico.”
