附睾
在生精小管持续产生的精子被移到位于每一侧睾丸表面的收集管道。这种收集管道叫附睾长约6米(20英尺)。但是,附睾是如此地迂回蟠曲,以至于并不比睾丸本身长。精子需要数周时间穿过附睾,在此期间,它们逐步发育,有了自己移动的有限能力。

The Internal Sex Organs: The System of Genital Ducts

The Epididymides
The sperm cells which are constantly being produced in the seminiferous tubules are moved into collection tubes which lie on the surface of each testicle. Such a collection tube is called epididymis (plural: epididymides), and it is about ca. 6m (20 feet) long. However, it is so twisted and convoluted that it seems no longer than the testicle itself. A sperm cell needs several weeks to traverse the collection tube. During this time it develops a limited ability to move by itself.
