Early exposure of does to sexually active bucks triggers early puberty onset correlating with neuroendocrine changes. However, the sensory pathways that are stimulated by male still unknown. Here, we assessed whether responses olfactory stimuli is modulated social experience (exposure males or not) and/or endocrine status (prepubescent pubescent). We used a calcium imaging approach on goat cells from main epithelium (MOE) and vomeronasal organ (VNO). For both cell types, observed robust hair in females under three physiological conditions: prepubescent isolated (ISOL PrePub), pubescent exposed (INT Pub) Pub). Response analysis showed overall greater proportion buck ISOL PrePub. hypothesized would be more responsive during prepubertal period, numerous perhaps originating immature neurons. also mature neurons MOE VNO INT Pub suggesting sexual can induce plastic changes function organization. To determine stimulation odor advance puberty, (ODOR). In ODOR (ISOL) groups, was reached one month after intact (INT), not sufficient trigger puberty.
