A type of pregnancy is known as surrogacy. In this case, a woman carries and delivers a baby for someone who is unable to have children. In a surrogate pregnancy, eggs are fertilized with sperm to make an embryo. The eggs may come from the woman who will carry the baby, or from an egg donor.
The embryo is implanted in the uterus of the surrogate mother, who carries the baby until birth. Surrogate pregnancy could be a possibility for those who wish to have children. This includes both men and women who have had medical conditions or treatments that can lead to infertility in women.
