Mechanism of LH and FSH Action on the Testis

  • Brian A. Cooke

Abstract

The testes fulfil a dual role analogous to that of the ovaries i.e. an endocrine function in the formation of steroid hormones and a germinal one in the production of spermatozoa. The seminiferous tubules are the site of spermatogenesis and they occupy approximately 85% of the gland volume. They are highly coiled (in the rat there are about 6 separate tubules) and are embedded in connective tissue containing the Leydig (interstitial) cells, the site of steroidogenesis. In contrast to the seminiferous tubules, the Leydig cells have an excellent blood supply. The whole testis is surrounded by a dense white inelastic capsule, the tunica albuginea.
