Explanation:

The testes are male reproductive organs. In biology, it is known that their main functions are sperm production (for reproduction) and testosterone secretion (a male sex hormone that plays roles in development, metabolism, etc.). Insulin and glucagon are produced by the pancreas. The kidneys filter waste from the blood. The body has various mechanisms (like sweating, shivering) to regulate body temperature. Estrogen and progesterone are mainly female sex hormones produced by ovaries (in females).

Produce sperm and testosterone
