@Richard42,
Yes, you are right. I'm also interested in surrogacy and I know, that there are 3 variants of it: one type of surrogacy involves getting an egg and some sperm and putting the fertilized egg (or eggs , it's usually more than one) into a woman's uterus (not the woman who provided the eggs) or , the surrogate provides the eggs and is artificially inseminated with her own fertilized eggs, or a procedure that just involves the sperm being transferred into the uterus of the surrogate so that conception happens naturally
