User:Mr. Ibrahem/Spermatocele

Spermatocele is a fluid-filled cyst in the epididymis. They occur behind or above the testicle. They vary in size from millimeters to a few centimeters. They are generally not painful; though some have a dull ache. They are not associated with infertility.

The cause is unknown. Proposed possibilities include injury, infection, and inflammation. The fluid they contain is usually milky colored and contain sperm. Diagnosis is based on examination and sometimes ultrasound. They are not cancer, nor do they increase the risk of testicular cancer.

They rarely require specific treatment. If pain occurs acetaminophen or ibuprofen may be used. Occasionally procedures such as aspiration or sclerotherapy, or surgery may be done. Spermatoceles occur in up to 30% males. They are more common in those in their 40s and 50s.
