Abstract:
To construct a semen bank, the collection of donated semen has to be done and an important concern is the safety of collected semen. The contamination is a big problem. Basically, the infectious pathogens can exist within donated semen, hence, a good donor screening is very important. Although viruses have an indirect role in sperm quality, but the evidence in banked semen is presently lack. This does not mean that there is no viral contamination but it might imply the inadequate concern on this issue. Contaminated semen usually means poor quality and hazardous to the recipient. The contamination of the virus in banked semen is a common problem in animal semen banking (1). The safety and transmission of each problematic virus is widely studied and well clarified in animal semen banking (2). However, this issue is not widely concerned in human semen banking. For sure, this case is an actual direct contamination and this cannot be detected if there is no specific screening in the banking process. The scenario of important new emerging viral infections will be specifically detailed in this report. West Nile virus is an emerging problematic viral infection that can cause a deadly clinical disorder. Basically, West Nile virus is classified as an arbovirus that is mainly transmitted by mosquito. However, the uncommon modes of transmissions such as transfusion related transmission are reported (3). The contamination of West Nile virus in semen is an important question in andrology. There is no evidence indicating for the presence of West Nile virus in the semen of the patients. However, American Society for Reproductive Medicine/Society for Assisted Reproductive Technology recommended that practitioners defer gamete donors who have confirmed or suspected West Nile virus infections (4).
