Exposure of anestrous females to a ram or his odour induces rapid secretion of LH that can lead to ovulation. This response is mediated by the main olfactory system (MOS) in sexually experienced ewes. The accessory olfactory system (AOS) has a minor, but unclear, role in this response. In sexually naive ewes, male odour is less effective than in experienced ewes, but the neural pathway involved is not known. In our experiment, we investigated the brain regions activated by the male or his odour… CONTINUE READING
