Dunham (surname) Dunham is a surname of Anglo-Saxon origination. The origins of the name may be in the Britannic place name âde Dinanâ (Dinan is a walled town in North West France). Alan, Barron de Dinan of Scotland carried the name to the United Kingdom with William the Conqueror in 1066.
Thus HCG sends the same message and results in increased testosterone production by the testis due to HCGâs effect on the leydig cells of the testis.
Specialized endocrine cells known as interstitial cells (the cells of Leydig) are responsible for the production and secretion of the necessary male sex hormones. Because of this, the testes are considered both endocrine glands as well as exocrine glands.
