If it is a gay male couple, they have two options for creating the embryo. On the one hand, they can decide who is going to contribute the sperm for fertilization, and create the embryo using his sperm and the egg from a donor. On the other hand, they can mix their sperm so that the egg is fertilized by a random spermatozoon, without knowing if the DNA belongs to father A or to father B.
