Studies on the effect of stress on the estrus cycle in rats.
Rats were studied for susceptibility to restraint stress in different phases of the estrus cycle. Susceptibility was measured by the duration of disorders of the estrus cycle. It was found that in proestrus and estrus the disorders of the cycle were most prolonged. During lower sexual activity female rats showed considerable resistance to stress, disorders of the estrus cycle being short-lasting.
