Which organ is responsible for the formation of sperm cells?

Explanation:
The organ that forms sperm cells is the testis. Spermatogenesis happens in the seminiferous tubules inside the testes, where germ cells divide and go through meiosis to become mature sperm. This process is supported by Sertoli cells and driven by hormones such as testosterone from nearby Leydig cells, with regulation from FSH and LH from the pituitary. Keeping the testes in the scrotum helps maintain a temperature slightly cooler than the body, which is important for proper sperm development. The liver, kidneys, and heart have different roles in the body—metabolism and bile production, filtering blood and forming urine, and pumping blood, respectively—so they do not form sperm.
