Gay couples who want to have children will need an egg donor. Who provides the eggs, as well as a surrogate, who will carry the pregnancy. The egg donor and surrogate can be two different women uses gestational surrogate. Or one in the same known as a traditional surrogate. Note that some states, however, mandate that the donor and surrogate must be two different women. These roles may be provided for gay men by their female relatives or friends. Alternatively, some fertility clinics, agencies and attorneys facilitate connections with surrogates and egg donors. Some clinics are able to combine the sperm of each partner with separate batches of the donors eggs. This could result in twins, each with the same biological mother, but separate dads. If only one child is born, a DNA test will be needed to determine which donor is the father. One partner’s female relative (e.g., a sister), could serve as the egg donor while her eggs would then fertilized by the sperm of the other partner. In this way, the child would be biologically related to both men.
