Conditions

Epididymal Cyst

Is it normal to be scared of the doctor? Vote now! >

An epididymal cyst is a smooth, fluid-filled lump found on the testicles. Although some men may worry that they are a sign of cancer or another serious problem, epididymal cysts are in fact benign and thus not a health risk.

The cysts form when fluid builds up in a tube behind the testicles called the epididymis, which stores and transports sperm. It is possible to have more than one cyst at a time and they can appear on both testicles. Up to a third of men are affected by this condition and the cysts can develop at any time in life, although it is most likely to occur in those who are middle-aged.

Epididymal cysts can be very small, but some can grow to the same size as a testicle or even as large as a grapefruit! There are normally no symptoms unless a cyst becomes infected, in which case it may drain fluid and become painful or swollen. Larger epididymal cysts can cause some discomfort, which is usually the reason why some men opt to have them removed. This procedure involves a simple operation to cut the cyst out of the epididymis. However, if a cyst is not infected and does not cause any pain or discomfort, it is not necessary to treat it.

Although epididymal cysts are benign, it is still important to get any new or unusual lumps and bumps in your genital area checked out by a GP.

I had a sebaceous cyst lanced and packed due to it becoming infected. I am still on iv antibiotics and getting packed. I keep it covered, so my question is... Should it be ok to have sex?

im 14 and when i was 13 i had a cyst on my testicle. The cyst became an issue however when it twisted causing agonising pain luckily i went straight to hospital and had surgery that morning leaving me in a great state with no worries however the incision area got infected and after the infection cleared i noticed spot like infections on my genetalia which is worrying to me but not a cause for alarm if you're ever in this situation just speak to your GP and it will be resolved with discression.

I have had a cyst from when I was about 16 and it had never botherd me now I'm nearly 30 I want to get it removed as it is causing some discomfort. Only I am petrified of using our local nhs hospital beacause of afew reasons, like every time I've ever had to go there I've had really really bad experiences, they have a bad reputation and I that would be the worst place to get an infection, a lot of the doctors there don't talk very clear English and this scares me. It is as you can imaging very important to me and as it reads on theses comments it says it is not that important which would probably mean an ugly scar of even worse they chop the wrong thing off lol I really don't trust these nhs doctors and is there any other option for me? :(

Hello, I've had 2 operatIons on what was called a hydrocele. We'll both didn't correct the problem. Should I possibly just have them take my left testicle and get an implant. My left teste hurts, well causes me great discomfort. It is just at my center of mass, I'm only relaxedwhem I can spread my legs far enough apart to not cause discomfort. I figure go in and have them take it, and put a prostheticss in there. What I ever be able to have children with this method. Thanks... Any one have prices on what this procedure will cost me? 😉cash only

I'm 25 and suffer from this. Discovered I had 2 cysts on left testicle last year. They were painful but nothing was done as pain went away after a few weeks. Went for another ultrasound a month ago after pain returning and i now have one on my right testicle. So that makes 3. Pain has been back with me now for a good few months and is gradually getting worse. My gp made a referral to Urology for me to discuss removing them. I'm taking Codeine 60mg 4x daily......Nefopam 90mg 3x daily and Amitriptyline 40mg at night for pain. Any input from people who suffers or have suffered from this is appreciated.
