This document summarizes key aspects of human reproductive anatomy and development in both males and females. It describes the major external and internal reproductive organs in females including the uterus, vagina, ovaries and mammary glands. It also outlines the descent of the testes in males. Additionally, it provides an overview of the main stages of egg and embryonic development including cleavage, blastulation and gastrulation.
