What is a surrogacy mother?
 A surrogate mother is a woman who carries a fetus for someone else, usually a couple struggling with fertility issues. After the child is born, the surrogate surrenders it to the people who have hired her. There are various forms of surrogacy, some of which have been used historically, while other are more modern.
One form of surrogacy, traditional surrogacy, involves using artificial insemination to impregnate the surrogate mother. This technique is often used when a woman is physically unable to bear children, but she still wants to have children with her partner. In this case, the partner donates sperm, or sperm is secured from a third party if he is infertile as well, and the surrogate contributes half of the required genetic material. This type of surrogacy has been around for centuries, although it was not widely discussed until the twentieth century, since some women felt ashamed because they could not bear children.
Modern surrogate arrangements usually involve gestational surrogacy. In gestational surrogacy, the couple commissioning the surrogate mother donate both eggs and sperm. The egg is fertilized in a test tube, and then implanted into the surrogate. In this case, she acts almost like an incubator, carrying the child to term for a woman who is unable to do so.
