The normal width of the epididymal duct is around 0.5 mm.
The epididymis is an important part of the male genitalia, and the epididymal duct is one of the tissues of the epididymis, which is an irregular curved tube with the tail connected to the vas deferens, which is not only conducive to the discharge of sperm, but also provides nutrients for sperm, and encourages sperm to continue to differentiate and synthesize hormones.
Under normal circumstances, the length of the epididymal ducts is usually around 5 to 6 cm, and their diameter is around 0.5 mm. However, due to the different age, height and testicular development of each patient, the width of the epididymal duct will vary accordingly, but will not become significantly wider or narrower. If abnormal reaction occurs, it may be related to tumors, stones, dysplasia and so on.
To summarize, if patients experience discomfort, it is best to go to the hospital for systematic examination and diagnosis.
