Functions of the Testis:

  • They produce male gametes called spermatozoa by the process of spermatogenesis.
  • The leydig cells of the seminiferous tubules secrete the male sex hormone called testosterone. Testosterone aids the development of secondary sex characteristics in males.

Functions of the ovary:

  • They produce female gametes called ova by the process of oogenesis.
  • The growing Graafian follicles secrete the female sex hormone called estrogen. Estrogen aids the development of secondary sex characteristics in females.
