Effect of continuous illumination (LL) on ovarian functions was compared at various ages between the rats exposed to LL from 70 days of age (LL-70) and exposed to LL from the day of birth (LL-0). LL-0 rats retained corpora lutea in their ovaries in higher incidence than LL-70 rats.
Effect of reserpine on the restoration of cyclicity was studied in LL-0 and LL-70 rats shortly after they became persistent-estrous. LL-0 rats restored cyclicity in higher incidence than in LL-70 rats.
