Surrogacy is a process in which a woman carries and gives birth to a child for another person or couple, who are usually unable to have children themselves. The surrogate mother may be artificially inseminated with the intended father's sperm, or she may carry a pregnancy resulting from donor eggs fertilized by the intended father's sperm. Surrogacy is often used as an option for couples who are unable to conceive naturally due to infertility issues, and can also be used by single individuals looking to become parents. The process of surrogacy involves legal contracts between all parties involved, including the intended parents, the surrogate mother, and any donors or clinics that may have been involved in the pregnancy.
