Abstract
Forty-eight Sprague-Dawley male rats were equally divided into three groups. Each S in Group I was given a fresh female immediately after each ejaculation, and 15 min after the refractory period half of the Ss were given new fresh females and the other half were interrupted by lifting and returning the same female. Group 2 was interrupted immediately after each ejaculation. Fifteen minutes after the refractory period half were given fresh females and half were interrupted. Group 3 was undisturbed immediately after ejaculation but at the 15th min of the refractory period half received fresh females and the other half were interrupted. Mating was observed until 45 min elapsed without male sexual responses. The results show no effect of immediate change or the change after 15 min of the refractory period. The course of male sexual satiation was not altered by the change. Thus, in spite of the same procedure, Fisher’s results (1962) were not replicated.
