Reproductive organs are specialized structures in the body that play a crucial role in the process of reproduction. In humans, these organs are divided into male and female systems. The male reproductive organs include the testes, which produce sperm, and the penis, which delivers sperm to the female. The female reproductive organs include the ovaries, which produce eggs, and the uterus, where a fertilized egg can develop into a fetus. These organs are essential for sexual reproduction, allowing for the combination of genetic material from two parents. Hormones such as testosterone in males and estrogen in females regulate the development and function of these organs, influencing secondary sexual characteristics and reproductive cycles.
