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've got quiet a few lumps over my testicles with a couple harder. I got them checks out a couple years ago and was over the moon to find out that they weren't cancerous. It does become slightly uncomfortable sometimes but no pain. Im thinking about getting them removed because I feel self conscious and is the main reason why I haven't gone all out seeking out a gf and at 22 this is just not what I want to be thinking about. Any advice? Surgery is pretty daunting

I am currently on my third course of antibiotic for epididymis and it is frightening, it's having a huge effect on my day to day life and it's pulling my relationship apart. It started 6 weeks ago and has been going since then. The pain goes when I sit or lay down but due to being a plumber I am up and down all day. I really want this to go! The third Dr I seen has referred me for an ultrasound which I am waiting for. This is so depressing! Feels like no one cares when I try to talk about it.

Hi, I was messing around a last week and a lego brick was thrown at me and hit me on the left testicle. I was wearing tracksuit bottoms (very loose) but the pain felt like was kicked. Usually the paid is gone within 10 mins but it is still sore today. I went to my GP yesterday and she thinks it could be a cyst. There is a lump there which is quite painful when touched. After looking online i have discovered that Cysts dont usually cause pain unless they are infected. I dont know what to do. Do i go to the doctors and demand a second opinion? She did say that she will book an ultra sound for the end of Jan. but what if the pain gets worse? It is throbbing now! Thanks.

In those aged over 40, epididymal cysts can be the result of being exposed to an artificial estrogen called diethylstilbestrol (or DES), that was widely used as a treatment for preventing miscarriages up until about 1980. If you were exposed to DES then it's important to know about it, because it can also result in a condition called hypogonadism (chronic below normal male testosterone production). Untreated hypogonadism is likely to result in you developing chronic debilitating illnesses as you get older, as well as completely destroying your quality of life. The symptoms to look out for include erectile dysfunction, loss of drive and motivation, "brain fog" and a general deterioration of your health. It's a lot like an accelerated ageing process. Hypogonadism as a result of DES exposure usually affects your development when you're younger too, resulting in you developing a characteristic "eunuchoid" body structure. This consists of such things as: * long, slender arms and legs * a leg length that's significantly greater than the height of your upper body (the two should be about equal in men) * an armspan 3cm or more greater than your height. * sparse or very fine body hair * a female "escutcheon" or pubic hair pattern (like an upside down triangle and confined to the pubic region) * an inability to build upper body muscle * feminine facial features and a generally feminine appearance (soft chubby features rather than hard muscular ones; gracile bone structure etc). * gynecomastica other things such as a female carrying angle, female digit ratio, absence of acne as a teenager, long, lushious eyelashes (in my case anyway). Basically you end up looking a bit like a cross between a man and a woman. It's much more noticeable during your teens and twenties; after that, testosterone (even at below normal male levels) is likely to have masculinised your body to the point where you don't stand out any more. Unfortunately, the NHS has an extremely poor track record when it comes to diagnosing and treating hypogonadism, however, if you have some or all of those symptoms, there are a number of online forums (such as androids.org.uk or allthingsmale.com) that may be able to offer support and advice on obtaining treatment.

Actually noticed this cyst 10 years and had an ultrasound. It was benign. Mu urologist at the time told me to where an athletic supporter. I did on occasion. So all this time I actually forgot about it. No pain or discomfort. Last week while properly bending to lift a heavy planter, I aggravated it and i have discomfort and low back pain on the same side. Should I stop working out til it heals? any home remedy,like heat, gentle whirlpool? thank you
