A mother, mom, mum, momma or mama, is a woman who has conceived, given birth to, or raised a child in the role of a parent. Because of the complexity and differences of a mother's social, cultural, and religious definitions and roles, it is challenging to define a mother to suit a universally accepted definition. The male equivalent is a father.

Biological mother

In the case of a mammal such as a human, a pregnant woman gestates a fertilized ovum. A fetus develops from the viable fertilized ovum or "embryo." Gestation occurs in the woman's uterus from conception until the fetus (assuming it is carried to term) is sufficiently developed to be born. The woman experiences labor and gives birth. Usually, once the baby is born, the mother produces milk via the lactation process. The mother's breast milk is the source of anti-bodies for the infant's immunen system and commonly the sole source of nutrition for the first year or more of the child's life.

Non-biological mother

Mother can often apply to a woman other than the biological parent, especially if she fulfills the main social role in raising the child. This is commonly either an adoptive mother or a stepmother (the biologically unrelated wife of a child's father). The term "othermother" or "other mother" is also used in some contexts for women who provide care for a child not biologically their own in addition to the child's primary mother.

Surrogate mother

A surrogate mother is, commonly, a woman who bears an embryo, that is from another woman's fertilized ovum, to term for a couple biologically unable to have children. Thus, she carries and gives birth to a child that is she not the biological mother of. Note that this is different from a woman who becomes pregnant via in vitro fertilization.

Currently, with advances in reproductive technologies, the function of biological motherhood can be split between the genetic mother (who provides the ovum) and the gestational (commonly known as a surrogate) mother (who carries the pregnacy).
