Despite the fact that a human female has a normal pregnancy duration (or gestational period) of 38 weeks, people often refer to pregnancy as a 40-week event. Why is this?
a. Because the heightened influence of teratogens in the world today has actually extended the duration of pregnancy from conception to delivery.
b. Because pregnancy usually begins two weeks after a woman's menstrual period, and that is the time from which the beginning of pregnancy is measured.
c. Because the duration of pregnancy actually gets longer as a woman ages, and it ranges from 38 to 42 weeks. 40 weeks is the average, so that is what people say.
d. Because physicians want to allow for a two-week window at the end of the pregnancy so that women do not become concerned if they have not delivered by the end of the 38th week.
