A male releases sperm when he ejaculates and a female releases an egg each month, during ovulation. It only takes one sperm to fertilize an egg. So, if an egg and sperm meet (an egg is fertilized), it travels down the fallopian tube and implants in the lining of the uterus. If this happens, a female becomes pregnant.
During the early stages of pregnancy the fertilized egg is called an “embryo.” As the embryo gets older it is called a “fetus.” It takes about 9 months for a fertilized egg to develop into a full term baby.
