I have a few small spermatic cysts ("spermatoceles"). They are small lumps - not tumors but fluid-filled cysts in the spermatic cord. I had them checked nby a doctor and he said they're very common, about 1/3 of all men have them, and they are usually caused by blockage of the sperm ducts, often as a result of trauma. My question is, does anyone else have experience with these? I wonder if DLD's testicle health program could help prevent new ones from forming by keeping the sperm ducts open? Or would testicle stretching actually cause new ones to form?
