In mature male seasonal breeders, the circannual cycles of testicular growth and involution involve significant changes in structure and function of both the tubular and interstitial testicular compartment. Roe deer (Capreolus capreolus) are seasonal breeders with a short defined rutting season from mid-July to mid-August and represent a unique non-rodent model for studying testicular functions during the course of a complete reproductive cycle with naturally changing photoperiod. Germ cells and Sertoli cells of the seminiferous tubules and the interstitial Leydig cells all display significant morphological and physiological alterations during the seasonal changes. In contrast to the germ cell population, Sertoli and Leydig cells persist as a numerically constant cell population in the roe deer testis. This report emphasizes the intricate relationship between seasonal cellular differentiation, intratesticular growth factor networks and their impact on the functional dynamics during the seasonal changes in roe deer testis.
