From: Increases in norepinephrine release and ovarian cyst formation during ageing in the rat
Changes in the number of preovulatory follicles, type-3 follicles, and cystic follicles in the ovary and in androstenedione and estradiol serum levels during aging in the rat. (A) represents number of type-3 follicles, (B) represents number of cystic follicles in ovary rat quantified like was described in methodology section and (C) androstenedione serum level and (D) estradiol serum levels during aging in the rat measured by EIA. Results are mean value ± SEM of n = 4 experiments. a = p < 0.05 vs 6, 8 and 10 months; b = p < 0.01 vs 6 and 8 month; c = p < 0.01 vs 6 months; d = p < 0.01 vs 6 months; e = p < 0.05 vs 8 months.
