Woman
A woman who has sex with a man, at the right time, may get pregnant, if no contraception is used. Contraception will stop a pregnancy.  When she gets pregnant,  the ovum of her menstrual cycle will be fertilized, and attach itself to the wall of the uterus. In humans, a pregnancy usually takes about 38 weeks. After this time, a child is born. For childbirth, a woman usually gets help from specially-trained people, called midwives. During the pregnancy, the woman should regularly see a doctor. Very often, these doctors are specialized, and are called gynecologists or obstetricians.
