The fertilization of the ovum may be achieved by artificial insemination methods, which do not involve sexual intercourse. Human reproduction normally begins with copulation, followed by nine months of pregnancy before childbirth, though it may be achieved through artificial insemination. Human reproduction naturally takes place as internal fertilization by sexual intercourse. As an alternative to natural sexual intercourse, there exists artificial insemination, where sperm is introduced into the female reproductive system. There are also many methods of assisted reproductive technology, such as in vitro fertilization, where one or more egg cells are retrieved from a woman's ovaries and co-incubated with sperm outside the body. ^ Sexual Reproduction in Humans.
