Abstrakt: Enhancement of illumination was shown to lead to occurrence of early and more obvious age-dependent changes of ovulation cycle in rats as compared with the same changes in animals staying in conditions of light deprivation or standard illumination. The effect of 24-hour illumination during a year induced more obvious and still earlier changes of the estrus cycle that the effect of natural illumination in the North-West of Russia with its peculiar yearly photo-periodicity (short light day in the autumn-winter period and "white nights" in the spring-summer period).
