CMV stands for cytomegalovirus and is a common virus that can infect everyone. In fact, most people have had a CMV infection by the time they turn 50 without being aware of it. They thereafter will have a positive CMV status.
Some of our donors are screened for their CMV status in order to accommodate use in some countries where testing for CMV is required. You can see the donors’ CMV status under each profile in the Sperm Donor Search. None of the donors who have been tested for CMV have an active virus at the time of donation. They are always tested for CMV both before and after the donation.
Since the donor can donate over an extended period of time, the donor’s CMV status can change from negative to positive. The samples which he has donated in the period where he has had a positive infection are disposed of and we do not accept new donations until the screening results show that the virus is no longer active.
An infection with CMV is mostly harmless. However, if a fetus is infected with CMV during pregnancy, the fetus could be at risk. Because of the regular sperm donor screening and the clean-up of sperm for IUI treatment, the risk is considered to be extremely low.
If you are concerned about CMV, we recommend that you are screened for CMV and discuss your results with your doctor.
