The weights of the testes and accessory glands, and the degree of morphological and functional development of the seminiferous tubules, were used as indicators of sexual maturation in male bank voles. Males reared under constant laboratory conditions showed a significant relationship between the seasons and sexual maturation. Young males reached maturity most rapidly in the reproduction season (mid-April to mid-October), while adult males matured earlier, in the spring season (mid-January to mid-April). The influence of season on animals reared in outdoor cages was much more pronounced. One of the important factors was the photoperiod: animals reared from 3 to 12 weeks of age in a short photoperiod (8L:16D) matured less rapidly than did those reared in 16L:8D.
睾丸和附属腺体的重量，以及曲细精管的形态和功能发育程度，被用作雄性小林姬鼠性成熟的指标。在恒定实验室条件下饲养的雄性小林姬鼠，其性成熟与季节之间存在显著关系。年轻雄性在繁殖季节（4月中旬至10月中旬）成熟最快，而成体雄性在春季（1月中旬至4月中旬）成熟更早。季节对户外笼养动物的影响更为显著。其中一个重要因素是光周期：在短光周期（8小时光照：16小时黑暗）下从3至12周龄开始饲养的动物，其成熟速度比在16小时光照：8小时黑暗条件下饲养的动物要慢。
