In practice, very little of this is checked for or marketed. They check for sexually-transmitted diseases, they check for non-negligibly likely genetic problems (e.g. Tay-Sachs in Ashkenazi-descended people, sickle-cell in West African-descended people). It’s possible someone is marketing sperm along the lines you posit, but I’d consider it non-negligible that they’re scamming.
