Table 2 Ovulation in rats with unilateral ovariectomy (ULO) performed at 13:00 h of diestrus-2 day

From: The participation of the muscarinic receptors in the preoptic-anterior hypothalamic areas in the regulation of ovulation depends on the ovary

Group Ovulation rate* Number of ova shed by the in situ ovary Weight of the in situ ovary (mg/100 g bw)***
Left ovary Right ovary Left ovary Right ovary
Intact 10/10 7.1 ± 0.5 5.4 ± 0.3 16.5 ± 1.2 15.6 ± 1.2
L-laparotomy 9/10 3.2 ± 1.3b 4.8 ± 2.6 14.9 ± 1.3 15.6 ± 1.4
L-ULO 1/10a 4** 32.7 ± 3.3a
R-laparotomy 10/10 6.2 ± 1.4 6.0 ± 1.1 24.9 ± 4.0b 21.7 ± 2.2b
R-ULO 3/9a 2.0 ± 0.6c 33.4 ± 3.6a
  1. The ovulation rate and the number of ova shed (mean ± SEMs) and weight of the left or right ovary of intact rats, or rats subject to left (L-laparatomy) or right (R-laparotomy) laparotomy, and those subject to left (L-ULO) or right (R-ULO) ULO were measured at the predicted estrus day
  2. a p < 0.01 vs. respective laparotomy group (Fisher’s exact probability test)
  3. b p < 0.01 vs. respective intact group (Kruskall Wallis test, followed Dunn test)
  4. c p < 0.01 vs. respective laparotomy group (Kruskall Wallis test, followed Dunn test)
  5. ***data statistically analyzed by ANOVA followed by Tukey test
  6. **represents the number of ova shed by the ovulating rat
  7. *Number of ovulating animals/number of treated animals
