睾丸的大小是估价男性生殖功能的一个重要指标,它与精液质量及生育力密切相关。睾丸重量的98%由曲细精管和生殖细胞组成,生殖细胞减少将引致睾丸发育不全。有两种方法测量睾丸大小。一是用游标尺测量睾丸的长度和宽度,另一种方法是用预制的睾丸容量模型进行比较性测定。两种方法各具优点,但随使用人员和方法的不同所获结果差异甚大。用游标尺测量即使睾丸位置适宜也很费事,而用塑料模型测量不一定精确。这就是在男性学临床上测量睾丸大小不易获得成功的原因之一。
Testicular size is an important indicator of male reproductive function, which is closely related to semen quality and fertility. 98% of testicular weight by the seminiferous tubules and germ cells, the reduction of germ cells will lead to testicular hypoplasia. There are two ways to measure testicular size. One is to use a slide rule to measure the length and width of the testes, and the other is to use a preformed testicular capacity model for comparative testing. The two methods each have advantages, but the results vary greatly depending on the person or method used. Measuring with a slide rule, even though the testicles are well-placed, can be cumbersome, whereas measuring with a plastic model is not always accurate. This is one of the reasons why it is not easy to clinically measure sperm size in men.
