The area of the granular tubules of the submaxillary gland was evaluated in male and female rats at 60 days of age. In males, this area was significantly greater than in females, corroborating the presence of sex dimorphism in this structure. Dimorphism disappeared after castration. Testosterone increased tubular area. Estrogen and progesterone as well as pregnancy reduced it. The tubular surface was significantly greater at term than at mid pregnancy.
对60日龄雄性和雌性大鼠颌下腺颗粒小管的面积进行了评估。在雄性大鼠中，该面积显著大于雌性大鼠，证实了该结构中存在性别二态性。去势后二态性消失。睾酮增加了小管面积。雌激素、孕激素以及怀孕则使其减小。足月时的小管表面积显著大于妊娠中期。
