Conditions

Epididymal Cyst

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'm 33 years old, I found my lump 8 years ago although it doesn't hurt it at all 6 months ago it has started to go smaller and smaller then it will grow back and it's kept doing this since. Is this normal? Also my wife and I have been try to conceive for at least 5 years my sperm tests show .5% motility and .1% morphology. During the last 6 months while the cyst has been shrinking and growing my sperm results changed slightly for the better if I had the cyst removed would this keep improving my results and help to finally conceive?

My spermatocele has nearly gone away. Both testicles were nearly twice the normal size for the last 5 years. Married 54 year old. I started juicing fan leaves from marijuana plants about 2 months ago and they both have returned to nearly normal. Juicing fan leaves is cannabinoids and no buzz. Any thoughts ? I juice for other benefits

I have an epididymal cyst that crowds me out. It throbs with persistent low level pain for hours. An ultrasound confirms it is "benign". So far the "benign" word seems to make doctors a bit dismissive. Regular painkillers just don't touch it.

Hello, I am 25 years old and 4-5 months ago I found a lump on the right side of my scrotum. It really made me anxious, but after about a week or so it went away so I never got it checked out. I did some research and found out it was a Epididymal cyst that was not cancer. Fast forward to about 5 days ago when it came back and started to grow larger (its about 1/3 the size of one of my testicle now) and I am seriously freaking out. I'm kind of hoping it goes away like last time but should I go to the doctor for some tests?

Yes. I've just done been for a similar reason. I have a scan tomorrow (15th) which he said is a precautionary measure / it's always better to know for sure.

I had two removed a year ago and now they are back, a bit of a waste of time, pain and money. however I do wonder if there is any association with a reduced flow in peeing and ejaculation - the cysts and reduced flow started to occour at the same sort of time.please comment if you have recent input

I had a cyst a couple of years ago that remained on my testicles without changing size. Had it checked/scanned to confirm what it was. Today found a large lump in the same place so went to the dr who believes it's the same thing although again having another ultrasound. Funnily enough I had not ejaculated in two weeks until last night before I found the cyst this morning so perhaps your theory is correct or holds some truth as I never noticed it before and I feel my balls a lot.

Hi there I am only 21yrs of age about 6months ago I felt a small lump on my left testicle it grows and shrinks on its on a bit of pains and discomfort here and there but the lump is free floating I'd say but its at the button of my left testicle but can move anywhere in the scrotum I haven't checked could it be cancer please help

Just get it checked out to be sure

I don't know how to explain my problems, but i have to, i actually was going through my balls and i found a lump that was kind of not wanting to move, i freaked out thinking it was cancer i constantly disturbed it to be sure it's not cancer, unfortunately for me something struck me after alot of pressure on it, it was a pain after 20minutes, although i have cyst i also pressured it during my thorough investigation, trust me i did an ultrasound and nothing was found. My question is that could it be that the pressure i constantly mounted on both the cyst and the lump(movable) ignited the pain? my testes has drammatically reduced too, please some1 should help.

Hi my partner had an operation a month ago to remove two cysts one on each side of his groin. On sunday he was a bit sensitive, on monday morning he felt a lump, which i thought could have been scar tissue. However, yesterday he was in pain in work and he was up all night in pain. When he got up this morning, to our horror, it burst slightly, so it is obviously another cyst. My partner is seriously angry about this because, although he was told they could come back, he never expected it so soon. I am making him an appointment with the GP today. I feel so sorry for him as he is in so much pain.
