For example, female Dog s usually have multiple Ovulation s in a single Estrus Cycle , and, when the Ova get fertilized, the animal gestates multiple offspring in one single pregnancy. The time interval of a gestation is called ''gestation period'', and the length of time the offspring have spent developing in the uterus is called '' Gestational Age ''. In humans, Parturition normally occurs at a gestational age of 37 to 42 weeks. Childbirth occurring before 37 weeks of gestation is considered preterm and has been associated with 70% of neonatal mortality and 75% of morbidity. A preterm fetus is considered viable only if it is delivered after the 28th week of gestation; before this age, those major developmental events that would allow the fetus to survive outside the womb have not occurred. |
