I purchased my donor sperm some time ago. 2012 I conceived my son on the first iui & saved my other vials for future siblings. I'm sure that at the time my search was based on a negative cmv status & id options donor. Now my donors status reads positive for cmv. Is it possible that his status changed since he first donated? I am concerned about my next pregnancy as I am cmv negative.

    It is possible for a donor to change CMV status from negative to positive. However, if you have vials in storage already, you can verify that they were CMV negative status by calling client services.

    How does Fairfax Cryobank screen its donors?
    Laboratory testing for antibody to CMV is performed on all donors. If the antibody test is negative or not detectable, the donor is presumed not to have been previously infected. A new test is done every three months to monitor for new infections. If the donor tests positive for antibodies, additional testing is performed to determine if the positive antibody test represents a recent or old infection. If a recent infection cannot be ruled out, all suspect semen vials are discarded.
