Insemination

For organisms that reproduce sexually, insemination is the transfer of male gametes (usually sperm) into the female reproductive tract, for the purpose of generating offspring. In mammals, this is the uterus, in birds, this is the oviduct. Insemination happens naturally during sexual intercourse, or copulation. It can also be done artificially, in which case it is called artificial insemination.
