W E Berndtson,E L Squires,D L Thompson,

The influence of season on spermatogenesis, testicular composition and the concentration of testosterone in the equine testis was evaluated using testes from 45 stallions. Testes were obtained through a commercial abbatoir during September, December-January, March and July. The weights of the testes, the tunica albuginea and testicular parenchyma and the proportion of the testicular parenchyma occupied by seminiferous tubules or interstitial tissue were similar during each season. How ever, diameter of the seminiferous tubules was greater in July than during other months of the study. In addition, the concentration of testosterone within the testicular parenchyma was twice as great during July as during the fall and winter, and this period of peak testicular testosterone concentrations was associated with spermatozoal production rates, which were 65% greater than those observed in September.
