What is Human Reproduction?

• Male Reproductive System: Includes organs such as the testes, vas deferens, and penis that produce and deliver sperm.
• Female Reproductive System: Includes organs such as the ovaries, fallopian tubes, uterus, and vagina that produce eggs and support fertilization and embryo development.
