Fig. 7From: Unilaterally blocking the muscarinic receptors in the suprachiasmatic nucleus in proestrus rats prevents pre-ovulatory LH secretion and ovulationInfluence of LHRH on ovulation in the rats that were microinjected with atropine. Ovulation rates of the rats subjected to microinjections of atropine in the SCN (ATR-SCN) at 09.00 h during proestrus and rats microinjected with atropine followed by injection with 3.7 μg/kg per body weight of synthetic LHRH at 14.00 h on the same day (ATR-SCN + LHRH). The animals were sacrificed 18–20 h after treatment on the predicted oestrus day. *p < 0.025 vs. the atropine group (Fisher’s exact probability test)Back to article page
