Captive breeding programs use reproductive technologies to help conserve endangered species.

Description

Artificial Insemination and In Vitro Fertilization

Artificial insemination (AI) involves collecting sperm from a male and inserting it into a female's reproductive tract without natural mating. In vitro fertilization (IVF) involves fertilizing eggs with sperm outside the female's body and then implanting the embryos into the female to develop.
