- Testes under the influence of FSH and LH.
- Leydig cells produce Testosterone and Androstenedione under the influence of LH.
- Provide secondary sex characteristics:
- Coloration
- Song during courtship
- Comb growth.
- Plumage and Bill colour
- Testosterone increases spermatogenesis and growth of accessory reproductive organs.
- Provide secondary sex characteristics:
- FSH initiates growth of semniferous tubules and results in increased spermatogenesis.
