Pregnancy (mammals)
In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. It begins when a fertilized zygote implants in the female's uterus; and ends once it leaves the uterus.

Famous quotes containing the word pregnancy:
“Back in the days when men were hunters and chestbeaters and women spent their whole lives worrying about pregnancy or dying in childbirth, they often had to be taken against their will. Men complained that women were cold, unresponsive, frigid.... They wanted their women wanton. They wanted their women wild. Now women were finally learning to be wanton and wild—and what happened? The men wilted.”
—Erica Jong (b. 1942)
