    Male hormones are secreted by the Interstitial or Leydig’s cells present in the stroma of connective tissue in between the seminiferous tubules in testis. They produce androgens (mainly testosterone) Sertoli cells are elongated epithelial cells present inside the seminal vesicle to nourish the growing spermatozoa.
