A more thorough explanation:

A surrogate carrier is a woman who carries a baby for someone else. This is usually done when the intended parents are unable to have a baby on their own. The surrogate carrier agrees to carry the baby in her uterus throughout the pregnancy and then gives the baby to the intended parents after birth.

For example, if a couple cannot have a baby because the woman cannot carry a pregnancy to term, they may choose to use a surrogate carrier. The surrogate carrier would carry the baby for them and then give the baby to the couple after birth.

Another example is when a single man or gay couple wants to have a baby. They may use a surrogate carrier and an egg donor to create an embryo that can be implanted in the surrogate carrier's uterus.

Overall, a surrogate carrier is a woman who helps others have a baby by carrying the pregnancy for them.
