Briefly, let's examine how conception takes place.
The ovaries manufacture eggs and female sex hormones.
The fallopian tubes extend from the ovaries to the uterus.
The neck of the uterus is the cervix, protruding into the upper wall of the vagina.
Each month, one egg matures and passes through the ovarian wall into the fallopian tube.
