sperm must fertilize the egg
Pregnancy can only occur when a male ejaculates semen into the female vagina. Then, the semen must travel through the cervix into the uterus and to the fallopian tubes, where the egg resides. Then, a sperm must implant into the egg, and the egg must travel down to the uterus and implant into the menstrual blood that is clinging to the uterine wall. Only when all of this is accomplished can pregnancy occur. Then the ovum, or embryo must be carried to term and born. Pregnancy does not happen every time two people have sex, but it is very common, so if you don't want a baby, wear a condom, or use some other form of contraception.
