Spermatozoa infected by Zika virus (green; arrowhead)

The Zika virus has been shown to be present in semen for as long as 6 months. However, recent work by Martin-Blondel et al  of the Infectious and Tropical Diseases Department of Toulouse University Hospital are the first to demonstrate the presence of the Zika virus in sperm. What is facinating is that in their index case the “ Zika virus was found to be present in all sperm samples only up to the 37th day. Beyond that point, the virus was found only in the semen, where it persisted for over 130 days.”

 

Implications of this does not change the recommendations for use of a barrier contraceptive however does support the use of washed sperm in in vitro fertilization sooner than 6 months after male exposure to the Zika virus. It also gives more impetus to test sperm donations for the Zika virus in fertility clinics. http://bit.ly/2cYlhrF
