When a man ejaculates inside a woman, sperm cells travel through the cervix and uterus, aiming to fertilize an egg in the fallopian tube. If fertilization happens, the egg becomes a zygote, which implants in the uterine lining, leading to pregnancy. This process requires precise timing within the woman’s menstrual cycle for successful conception.
