Steroid hormone serum levels of the rats treated at 09.00 h on the proestrus day. The means ± the SEMs for the progesterone (ng/ml) and oestradiol serum levels (pg/ml) of the non-ovulating and ovulating rats that received microinjections of the vehicle in the left (Vh L-SCN) or right (Vh R-SCN) SCN or atropine microinjection in the left (ATR L-SCN) or right (ATR R-SCN) SCN at 09.00 h during proestrus. (1) Represents the level of one animal’s ovulation. * p < 0.01 vs. the respective groups microinjected with Vh (ANOVA followed by Tukey’s test). ♦p < 0.05 vs. ATR-L-SCN (ANOVA followed by Tukey’s test)
