In a number of species, including rats and mice (Bartke, Steele, Musto & Caldwell, 1973), bulls (Katangole, Naftolin & Short, 1971), and rams (Purvis, Illius & Haynes, 1974), there is evidence of episodic fluctuation of circulating levels of testosterone. It has generally been concluded that testosterone is released from the testis in a pulsatile fashion, temporally related to the episodic release of LH (Katangole et al., 1971; Moor & YoungLai, 1975).
