大鼠生精小管组织结构增龄变化的研究

Study on the Tissue Structure Changes of the Seminiferous Tubules in the Testis of the Rat with Aging

比较观察了从出生到生后 1 2月龄大鼠睾丸生精小管在生长发育过程中组织结构的变化 ,结果发现 :1 .生精小管平均横切面面积从出生到生后 6月龄迅速增大 ,从生后 1 0月龄到生后 1 2月龄生精小管平均横切面面积逐渐减小 ;2 .生精小管平均横切单位面积内精原细胞数量从出生到生后 6月龄迅速减少 ,从生后1 0月龄到生后 1

Tissue structure changes of the seminiferous tubules from birth to 12 months after birth are comparatively researched in the article.The results show that:1.The average area of cross section in the seminiferous tubules has increased from birth to 6 months after birth,while it has decreased from 10 months to 12 months after birth;2.The average quantity of spermatogonia per unit area in cross section of seminiferous tubules has decreased from birth to 6 months after birth,while it has increased from 10 months to 12 months after birth.
