Spermatozoa of scrotal mammals will mature in, but cannot be stored at abdominal temperatures in the epididymis reflected to the abdomen. Whether the failure of sperm storage at abdominal temperatures reflects a temperature sensitivity of the caudal epithelium, or of the spermatozoa, is unknown. Microperfusion of the lumen of the cauda epididymis revealed that abdominal temperature soon brings a significant change in the transepithelial transport of water, Na+, K+ and Cl-, and in the Na+ and K+ levels in the luminal fluids in the cauda. Thus, the cauda epididymis, as well as the testis, behaves as a temperature-dependent organ.
阴囊哺乳动物的精子可在附睾中成熟，但无法在反映至腹部的附睾中于腹部温度下储存。精子在腹部温度下无法储存是由于附睾尾上皮对温度敏感，还是精子本身对温度敏感，目前尚不清楚。对附睾尾管腔进行微量灌注显示，腹部温度很快会使水、钠、钾和氯的跨上皮转运以及附睾尾管腔内液体中的钠和钾水平发生显著变化。因此，附睾尾以及睾丸都是温度依赖性器官。
