Ovaries: about once a month, one of the woman’s ovaries releases a tiny egg into the tube
Tube: the egg moves down the tube and into the womb
Womb: where a baby grows if the woman becomes pregnant

When the man ejaculates (comes, climaxes) in or near the vagina, his sperm leave his penis and can get into the womb and tubes. During the woman’s fertile time, the sperm can join with the woman’s egg. If the sperm fertilizes the egg, it then plants itself in the lining of the woman’s womb. This is pregnancy. Family planning methods prevent pregnancy by keeping sperm out of the vagina, or by stopping a woman’s body from releasing eggs, or by stopping sperm from joining with an egg.
