2. Epididymal cyst - Wikipedia

   en.wikipedia.org/wiki/Epididymal_cyst

   The exact cause of an epididymal cyst is unknown, but it is most likely a congenital anomaly associated with hormonal imbalances during embryonic life. [3] Previous research has shown a correlation between the development of epididymal cysts and maternal exposure to endocrine disrupting substances like diethylstilbestrol during male fetal development.

3. Spermatocele - Wikipedia

   en.wikipedia.org/wiki/Spermatocele

   Spermatocele is a fluid-filled cyst that develops in the epididymis. [3] The fluid is usually a clear or milky white color and may contain sperm. [4] Spermatoceles are typically filled with spermatozoa [5] and they can vary in size from several millimeters to many centimeters.

4. Epididymitis - Wikipedia

   en.wikipedia.org/wiki/Epididymitis

   Tests are needed to distinguish chronic epididymitis from a range of other disorders that can cause constant scrotal pain including testicular cancer (though this is often painless), enlarged scrotal veins , calcifications, [15] and a possible cyst within the epididymis. Some research has found that as much as 80% of visits to a urologist for ...

5. Ejaculatory duct obstruction - Wikipedia

   en.wikipedia.org/wiki/Ejaculatory_duct_obstruction

   However, transrectal ultrasound has a relatively low sensitivity of approx. 50% and thus is only a tool to rule-out cysts in the region of the orifices but is not sufficient to rule out an obstruction of the ejaculatory ducts due to other causes. In approx. 50% of cases of unexplained low-volume azoospermia MRI and TRUS do not reveal any ...

6. Sperm granuloma - Wikipedia

   en.wikipedia.org/wiki/Sperm_granuloma

   Sperm granulomas appear as hard and firm nodules that do not exceed 1 cm in size. Sperm granulomas form in 20-50% of vasectomy procedures. [6] An injury to the epididymal epithelium is caused by penetration of germ cells into the epididymal supportive tissue. This infiltration of germ cells allows for the pathogenesis of sperm granulomas.

7. Cyst - Wikipedia

   Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
