A mature egg is released from the ovaries and if a sperm fertilizes it, a baby is conceived. Conception occurs when a sperm cell from a fertile man swims up through the vagina and into the uterus of a woman and joins with the woman’s egg cell as it travels down one of the fallopian tubes from the ovary to the uterus.
