A morphometric study of rat testis development and ageing (from 5 to 360 days of age) has been carried out. The testicular volume increases from 10.28 +/- 0.35 mm3 (5 days of age) to 1819.43 +/- 52.67 mm3 (360 days of age), showing the most rapid increase between 20 and 70 days of age (22.6 times). The mean tubular diameter increases from 62.25 +/- 1.50 micron (5 days of age) to 280.81 +/- 9.77 microns (360 days of age) and the tubular length from 2.74 +/- 0.18 m (5 days of age) to 25.45 +/- 1.76 m (360 days of age). Up to 15 days of age, the increase in testicular volume was mainly due to the increase in tubular length, whereas from this age onwards the tubular growth was similar in both length and diameter. Tubular development had nearly finished at 70 days of age.
对大鼠睾丸发育和衰老（5至360日龄）进行了一项形态测量学研究。睾丸体积从10.28±0.35立方毫米（5日龄）增加到1819.43±52.67立方毫米（360日龄），在20至70日龄之间增长最为迅速（增长了22.6倍）。平均曲管直径从62.25±1.50微米（5日龄）增加到280.81±9.77微米（360日龄），曲管长度从2.74±0.18米（5日龄）增加到25.45±1.76米（360日龄）。在15日龄之前，睾丸体积的增加主要是由于曲管长度的增加，而从这个年龄开始，曲管在长度和直径上的生长相似。曲管发育在70日龄时几乎完成。
