Table 1 Ovulation in rats with unilateral atropine microinjection into POA-AHA 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 Side of POA-AHA n Ovulation
rate*
Ova shed
Left ovary Right ovary
Intact 10 10/10 7.1 ± 0.5 5.4 ± 0.3
Vehicle Left 9 9/9 6.1 ± 0.9 4.2 ± 1.0
Right 9 9/9 6.5 ± 0.2 4.8 ± 0.3
Atropine Left 10 2/10a 4, 0** 3, 3**
Right 10 10/10 3.1 ± 0.3b 1.7 ± 0.2b
  1. The ovulation rate and the number of ova shed (mean ± SEMs) by rats subjected to microinjection of the vehicle or atropine into the left or right side of the POA-AHA region were measured at the predicted estrus day
  2. a p < 0.0007 vs. left vehicle (Fisher’s exact probability test)
  3. b p < 0.001 vs. right vehicle (Kruskall Wallis test, followed Dunn test)
  4. **represents the number of ova shed by the two ovulating rats
  5. *Number of ovulating animals/number of treated animals
