Initially the single blastocyst is confined to a chamber in the fundus of the uterus simplex during a prolonged period of delay of implantation. . Main Idea: Animals have specialized structures for sexual reproduction.. Gonads-specialized reproductive organs that produce sperm or eggs. Ovaries produce egg cells . Testes produce sperm. Female.

Fertilization: This is the process whereby the sperm meets the egg and genetic material (chromosomes) is mixed. ½ + ½ = 1 complete set. Implantation: This is the process whereby an embryo becomes embedded within the uterine lining. Lesson 15.2: Male Reproductive System Anatomy and Physiology.
