Sexual intercourse, or copulation, is the deposition of sperm into a female via a male intromittent organ.In humans, the intromittent organ is the penis, and sperm are deposited into the vagina, where they make their way to towards the uterus to fertilize an egg. Male plants and animals produce smaller gametes (spermatozoa, sperm) while females produce larger ones (ova, often called egg cells).
