To determine if kisspeptin could be implicated in the control of reproduction in equine species, we studied the distribution of kisspeptin neurons and their anatomical interactions with GnRH neurons in the hypothalamus of pony mares. Brains were collected in three pony mares between 2 and 4h after ovulation. One major population of kisspeptin immunoreactive cell bodies was found in the arcuate nucleus (ARC), where they extended from the middle of the nucleus to the premammillary recess. Kisspeptin immunoreactive varicose fibers extended from the preoptic area to the mammillary nuclei, with important densities especially in the anterior periventricular area and the median eminence (ME). Rare close appositions of kisspeptin fibres on GnRH cell bodies were observed in the ARC. Close appositions between kisspeptin and GnRH fibres were also confirmed at a low incidence in the anterior basal periventricular area and at a high incidence in the ME. This work provides neuroanatomical bases for further investigations into the role of kisspeptin in equine reproduction.
