Résumé :	This study evaluates whether short daily male-conspecific visits influence the dynamics of endocrine testicular and adrenal photo-responsiveness. A group of male Japanese Quail was exposed to short photoperiods and another group to long photoperiods. The quail exposed to short photoperiods were classified as responsive (SD-R) or non-responsive (SD-NR), depending on whether or not they lost their reproductive condition after 5 weeks of short days (SD). Individuals kept on a long photoperiod were used as controls (LD). After photoperiodic classification and during four consecutive days, individually-caged SD-R, SD-NR and LD resident male quail received 5-min visits from photo-stimulated (and therefore sexually active) male quail (social treatment). Cloacal gland volume (CGV), and androgen and corticosterone metabolites (AM and CM, respectively) in droppings were measured bi-weekly and evaluated by repeated measures ANOVA over a 6-week period. Immediately after photoperiodic classification and before social treatment, CGV, AM and CM values showed a SD-R
