Pregnancy over the age of 50 has, in recent years, become possible for more women, and more accessible for many, due to recent advances in aid reproductive technology, especially egg donations. Usually, a woman's fecundity ends with menopause, which by definition is 12 consecutive months without having menstrual flow at all. During perimenopause, the menstrual cycle and menstruation become irregular and eventually stop completely, but even when menstruation is still regular, the quality of the eggs of women in their forties is lower than in younger women, making the chances of conceiving a healthy baby also diminishing, especially after age 42. It is important to note that women's biological clocks can vary greatly from woman to woman. A woman's fertility level can be tested through various methods.
Men also experience decreased fertility as they age in a very gradual process and then different from female fertility when the biological clock of men decreases only with each age (loses 1 percent of age) compared to the woman's biological clock where it begins to fall sharply and rapidly after 38 years; for example, the average time for pregnancy if a man under 25 is over 4.5 months but almost two years if a man is over 40 years old (if a woman is under 25). The risk of genetic defects is greatly increased due to the effects of the father's age. Children with fathers aged 40 or older are more than five times more likely to have autism spectrum disorders than father children by men under the age of 30. Researchers estimate that compared to a man who fathered a child in his early 20s, there is a doubling of the chances of a child getting schizophrenia when the father is 40, and three times the risk of schizophrenia when the father is age 50 (though, for most people this means the risk runs from about 1 in 121 when a man is 29, to 1 in 47 when a man is 50 to 54). Male fertility declines over lifetime, with the volume and fecundity of male sperm quality and sperm motility (sperm's ability to move toward the egg) continues to decline between the ages of 20 and 80. Incidence of dwarfism and miscarriage also increases as men age
In the United States, between 1997 and 1999, 539 births were reported among mothers over the age of 50 (four per 100,000 births), with 194 over 55.
The oldest mother to be pregnant, 71 years old, and the youngest mother, 5 years old. According to statistics from the Human Fertilization and Embryology Authority, in the UK more than 20 babies are born to women over the age of 50 per year through in-vitro fertilization with the use of donor oocytes (eggs).
Maria del Carmen The Bousada de Lara is the verified oldest mother; he was 66 years old 358 days when he gave birth to twins; he is 130 days older than Adriana Iliescu, who gave birth in 2005 to become a baby girl. In both cases, children are conceived through IVF with donor eggs. The oldest verified mother who is naturally pregnant (currently registered on January 26, 2017 at Guinness Records) is Dawn Brooke (UK); he conceived a son at the age of 59 years in 1997 while taking estrogen.

The risk of pregnancy complications increases with age. Risks associated with childbirth over age 50 include increased incidence of gestational diabetes, hypertension, delivery by caesarean section, miscarriage, preeclampsia, and placenta previa. Compared to mothers aged between 20 and 29, mothers over 50 are almost three times at risk of low birth weight, premature birth, and premature births; the risk of birth weight is very low, small size for gestational age, and fetal death almost doubled.

The facts about the concept of pregnancy in this age group can be difficult to determine, but they are almost always due to the use of IVF with donor eggs.
Debate
Pregnancy among older women has been the subject of controversy and debate. Some people oppose motherhood in the elderly on the basis of the health risks involved, or for fear that older mothers may not be able to provide proper care for a child as he gets older, while others think that having a child is a basic right and that is commitment to the well-being of the child, not the age of the parent, is important.
A survey of attitudes toward pregnancy over the age of 50 years among Australians found that 54.6% believed it was acceptable for a postmenopausal woman to move her own eggs and that 37.9% believed it was acceptable for a postmenopausal woman to receive eggs or embryo donated.
Governments sometimes take action to regulate or limit the fertile period in a child's life. In the 1990s, France approved a bill banning postmenopausal pregnancy, which the then French Health Minister, Philippe Douste-Blazy, said was "... immoral and dangerous for maternal and child health". In Italy, the Association of Medical Practitioners and Dentists prevents its members from providing women aged 50 and over with fertility treatments. The British Secretary of State for Health, Virginia Bottomley, stated, "Women have no right to have children, children have the right to a suitable home". However, in 2005, age restrictions on IVF in the United Kingdom were formally withdrawn.
Legal restrictions are just one of the obstacles facing women seeking IVF, as many fertility clinics and hospitals set their own age limits.
