Carriers are overall healthy (there are only like incredibly rare exceptions to this). Also newsflash, we all carry several recessive diseases, some of which can be screened for, a lot of which can't. So as long as egg donor isn't a carrier for something your husband carries, it's not an issue. Speak to a genetic counselor.
This. If your husband or sperm donor is not a carrier, it's not an issue. If husband/sperm donor is a carrier, though, I would not.
For example, I got the full Ashkenazi Jewish panel. I am a carrier for Tay-Sachs disease, which was not a surprise as I had two cousins who died from it decades ago before the disease was widely known. So DH got tested but he is not a carrier, so we were fine to TTC without doing PGS. My sister also was tested when they were TTC and was not a carrier so they did not bother to test her husband (half Jewish).
