The surrogate has no genetic connection to the baby. Full or gestational surrogacy is when a fertilised donor egg is implanted into a surrogate through in vitro fertilisation (IVF). These days, more same-sex male couples are creating their own families through surrogacy. Or a gay man can donate sperm to a single woman or same-sex female couple to have a baby. A gay couple may have a co-parenting arrangement with a lesbian couple. One or both of you may have children from a previous heterosexual relationship, or you may decide to adopt. For example, a bisexual man may have a baby with a heterosexual woman. Same-sex families can be created in many different ways.
