How can differentiate those who put egg and deliver baby?

Answer 1

It is all going to depend on the circumstances. In a traditional pregnancy, the woman's egg/s is fertilized by the man's sperm and a baby is born. The woman is the mother and the man the father. In cases of infertility, an egg donor may be used. In this case, a healthy woman donates her eggs so that an infertile couple can use them (the egg donor relinquishes all parental rights to her eggs- she will NOT be the mother). The couple then acquires the eggs, usually via a fertility clinic, then the egg is inseminated with the sperm in the lab and transferred to the woman via IVF (In-Vitro Fertilization). The woman gives birth and is considered the mother. In the case of surrogacy, usually due to illness or disease, a surrogate mother is used. Gestational surrogacy uses the IM's (Intended Mother) eggs or donor eggs (never her own) and the IF's (Intended Father) sperm or donor sperm via fertility clinic and IVF and carries the baby/ies to term and gives them to the IM and IF. The surrogate has no genetic ties to the children and is NOT the mother. The mother for whom the surrogacy was done for is considered the Mother. It is her name and her spouse's name that appear on the birth certificate.
