Pregnancy lasts approximately nine months, after which the baby, if born naturally, is born via the birth canal. Pregnancy in animals other than humans is referred to under the broader term of [[gestation]]. In humans, the terms "gestation" and "pregnancy" are not exactly synonymous. Physicians and midwives generally use the former word when discussing it from the fetus' perspective (e.g., ''Hearing develops between the 15th and 20th week of '''gestation''' ''), and the latter word when discussing it from the mother's perspective (e.g., ''Morning sickness generally subsides between the 15th and 20th week of '''pregnancy''' ''). | Pregnancy lasts approximately nine months, after which the baby, if born naturally, is born via the birth canal.
