A cyst is a fluid-filled sac that may occur in the testicle. Most of them may be benign. In order to rule out any anomalies, you may need to follow up with your doctor. He should let you know if they do cause health problems such as infertility. For example, sperm sac, also known as a spermatic cyst, is usually a painless, non-cancerous cyst that grows from the epididymis near the top of the testicle. These testicular cysts are smooth and filled with milky or clear liquids containing sperm. You may need to pay close attention to them to see if they are stable or growing. If it enlarges or causes pain, then you may need proper medical care.
