Abstract

SUMMARY Objective: This study had the objective of acquiring information about the histology and development of ovarian follicles of female rats kept in the absence of light. Material and Methods: 10 albino female rats were used and divided into two groups of five: GROUP I – Female rats kept in the dark-light cycle 12/12 hours, for three months (Control), and GROUP II – female rats kept in the absence of light for three months. Results: in the rats of group II, a predominance of corpus luteum and some ovarian follicles in the initial phase of development was observed in the cortical area to the ovaries, while few dispersed interstitial cells were evidenced in the ovarian stroma, in the medullar area. Conclusion: The absence of light can bring about an increase in the level of melatonin in the blood and consequently, it can contribute to the maintenance of corpus luteum and reduce the activity of synthesis of steroids present in the interstitial cells of the ovary. DESCRIPTORS Ovaries. Histology. Melatonin. Photoperiod.
