Biological mother Biological motherhood for
humans, as in other
mammals, occurs when a
pregnant female gestates a fertilized ovum (the "egg"). A female can become pregnant through
sexual intercourse after she has begun to
ovulate. In well-nourished girls,
menarche (the first
menstrual period) usually takes place around the age of 12 or 13. Typically, a
fetus develops from the viable
zygote, resulting in an
embryo.
Gestation occurs in the woman's
uterus until the fetus (assuming it is carried to
term) is sufficiently developed to be born. In humans, gestation is often around 9 months in duration, after which the woman experiences labor and gives birth. This is not always the case, however, as some babies are born
prematurely, late, or in the case of
stillbirth, do not survive gestation. Usually, once the baby is born, the mother produces
milk via the
lactation process. The mother's
breast milk is the source of
antibodies for the infant's
immune system, and commonly the sole source of nutrition for newborns before they are able to eat and digest other foods; older infants and toddlers may continue to be breastfed, in combination with other foods, which should be introduced from approximately six months of age.
Childlessness is the state of not having children. Childlessness may have personal, social or political significance. Childlessness may be
voluntary childlessness, which occurs by choice, or may be involuntary due to health problems or social circumstances. Motherhood is usually voluntary, but may also be the result of
forced pregnancy, such as
pregnancy from rape. Unwanted motherhood occurs especially in cultures which practice
forced marriage and
child marriage.
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
partner 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. Adoption, in various forms, has been practiced throughout history, even predating human civilization. Modern systems of adoption, arising in the 20th century, tend to be governed by comprehensive
statutes and
regulations. In recent decades,
international adoptions have become more and more common.
Adoption in the United States is common and relatively easy from a legal point of view (compared to other Western countries). In 2001, with over 127,000 adoptions, the US accounted for nearly half of the total number of adoptions worldwide.
Surrogate mother A surrogate mother is a woman who bears a child that came from another woman's fertilized ovum on behalf of a couple unable to give birth to children. Thus the surrogate mother carries and gives birth to a child that she is not the biological mother of. Surrogate motherhood became possible with advances in
reproductive technologies, such as
in vitro fertilization. Not all women who become pregnant via in vitro fertilization are surrogate mothers. Surrogacy involves both a genetic mother, who provides the ovum, and a gestational (or surrogate) mother, who carries the child to term.
Lesbian and bisexual motherhood The possibility for
lesbian and
bisexual women in
same-sex relationships to become mothers has increased over the past few decades due to technological developments. Modern
lesbian parenting originated with women who were in heterosexual relationships who later identified as lesbian or bisexual, as changing attitudes provided more acceptance for non-heterosexual relationships. Other ways for such women to become mothers is through adopting,
foster parenting or in vitro fertilization.
Transgender motherhood Transgender women may have biological children with a partner by utilizing their sperm to fertilize an egg and form an embryo. For transgender women, there is currently no accessible way to carry a child. However, research is being done on
uterus transplants, which could potentially allow transgender women to carry and give birth to children through
Caesarean section. Other types of motherhood include adoption or foster parenting. However, adoption agencies often refuse to work with transgender parents or are reluctant to do so. ==Social role==
