In the described situation, unrelated (i.e. not of a husband and wife) sperm and ovum are being used, which is impermissible in light of the Hadith. The way sexual relations between unrelated, (i.e. not husband and wife) man and woman and impregnating somebody else's wife constitutes adultery, in the same way mixing the sperm and ovum of a man and woman, who are not husband and wife, has the same ruling with respect to its result. Though on mixing of sperm and ovum in this, the Shariah punishment will not be given, as the punishments given by the Shariah are not given even if there is the slightest of doubt and in this case, physical contact is not found at all, but it has the same ill-effects as adultery. It shreds the fabric of modesty and destroys the system of parentage and ancestry.
