CMV and standards for screening

What is CMV status?

CMV stands for Cytomegalovirus. It is a very common virus, which most people have had before turning 50 years old. Approximately 50% of people aged 20 have been temporarily infected with this virus.

We only screen some of our donors for CMV to accommodate use in certain countries. We only accept sperm from a donation period where the donor was IgM negative (did not have an active infection). In these countries, sperm from a donor who has previously had the infection and is now IgG positive may only be used for women who themselves are IgG positive (who have had the infection earlier).

An infection with CMV is mostly harmless. However, if a fetus is infected with CMV during pregnancy, the fetus could be at risk. This can happen if the mother has a primary infection of CMV during pregnancy.  Because of the regular screening for IgM antibodies and the clean-up of sperm for IUI (centrifuging), the risk is considered to be minuscule.

The donors who have no CMV status on the website have not and will not be screened for this.

For all donors tested the status will show on the website.

What is a standard?

As countries have different regulations regarding selection, screening, and approval procedures for donors and donor sperm, as well as different requirements for documentation, Cryos operates with different "Standards" for release. A donor/ejaculate can be released according to one or several Standards. 

Donors/ejaculates can be released according to the Standards in Denmark (DK), EU, Finland (FI), Holland (NL), Israel (ISR), Italy (ITA), Norway (NO), New York State (NYS), United Kingdom (UK), and United States of America (USA).

For treatment by a professional in one of the above countries you should use the relevant Standards. For treatment by a professional in another country than mentioned above please ask the professional for assistance.

It is the client's responsibility to ensure that import and handling is legal in the destination country.
