I have just tested CMV negative. Unfortunately, the clinic only has CMV positive donor sperm at the moment. I'm due to start IVF stimulation in 3 weeks time and am wondering what risks are attached to using CMV positive sperm. Any answers comments most welcome?
The following link relates to cmv and donor eggs. You will need to confirm with your clinic, but I would imagine that the principle is the same for donor sperm (I am not 100% sure though as I am not a fertility nurse)
It is the same principle for eggs or sperm. If you are CMV-ve, there is the risk of contracting it in poregnancy if using a cmv+ve donor which can cause blindness and foetal abnormalities, hence the need to match.
