Between the seminiferous tubules are interstitial cells which secrete which of the following hormone?

Correct answer: C. Testosterone

  • A. Progesterone
  • B. Estrogen
  • C. Testosterone
  • D. Oxytocin

Explanation

Between the seminiferous tubules in the testes are interstitial cells, also known as Leydig cells. Leydig cells are responsible for secreting the male sex hormone testosterone. Testosterone plays a crucial role in the development and maintenance of male reproductive tissues and the expression of male secondary sexual characteristics. It influences the development of the testes, promotes the production of sperm in the seminiferous tubules, and is involved in the development of male secondary sexual characteristics such as facial hair, deepening of the voice, and increased muscle mass.
