The paired male sex glands, the testicles (testicles) and the paired secretory organ, the epididymis (testicular appendages), produce spermatozoa and, to some extent, the hormone testosterone. In the upper part of these glands, in the area of their appendages or along the spermatic cord, a testicular cyst is often formed - a cavity with a fibrous membrane and liquid contents. Testicular cysts are benign tumor-like formations.
According to localization, these formations are divided into left-sided - a cyst of the left testicle, right-sided - a cyst of the right testicle, and bilateral - simultaneously in both testicles or cysts of the appendages of both testicles.
Causes of testicular cyst
The causes of testicular cysts have not yet been fully clarified. Among the most probable causes of this pathology is the expansion of the testicular membrane or its appendage due to a limited protrusion of their walls (aneurysm) with subsequent narrowing and formation of a cavity. But why this happens is not exactly known. Although factors such as the presence of an infection or traumatic impact on the scrotum may play a decisive role here. It is believed that this pathology can be both congenital and acquired.
And here is a cyst of the left epididymis and a cyst of the right epididymis (spermatocele)
It is formed when the release of the excretory ducts is disrupted and they are filled with fluid, which is produced by the epididymis for the maturation and transportation of spermatozoa. If the scrotum has been injured, blood has stagnated in it, or inflammation has occurred, the seminal ducts narrow (up to complete blockage). As a result, the ejaculate accumulates, stretching the walls of the seminal ducts, and thus a pathological cavity is formed - a cyst.
The cause of the epididymis cyst can also be acute epididymitis - an infectious inflammation of the testicle or epididymis caused by gonococci, chlamydia, mycoplasma, ureaplasma, trichomonas and various viruses. As a rule, this disease is a complication of prostatitis, vesiculitis or urethritis - against the background of hypothermia, decreased immunity and scrotal injuries.
Since pathological formations in the testicles can be congenital, a testicular cyst in a child can be detected even immediately after birth. These are dysontogenetic cysts, the etiology of which is associated with fetal development disorders in the first half of pregnancy, as well as with the birth of a child ahead of schedule or an injury received during childbirth.
If the cyst does not begin to grow, then very often it disappears without any treatment. And if the size of the testicular cyst in a child increases, then it is removed using laparoscopy.
Symptoms of a testicular cyst
The clinical picture of a cystic formation in the testicle or a cyst of the epididymis develops from an asymptomatic stage of the disease to the manifestation of signs associated with a gradual increase in the size of the cavity.
According to observations by urologists, in cases of testicular cyst diagnosis, most patient visits were related to their independent detection of a small (pea-sized) round or oval lump in the scrotum next to the testicle – without the slightest complaint of pain.
With a cyst size of 2-2.5 cm, a man may feel discomfort in the scrotum area. An increase in the size of the left testicle cyst or the right testicle cyst can cause quite noticeable discomfort when moving, walking, and also during intimacy.
When the cyst diameter is 3-3.5 cm and higher, the vessels and tissues of the testicle (compression ischemia) are compressed, as well as its nerve endings, resulting in the formation of foci of congestion. This manifests itself in the form of pulling pains, which are localized in the scrotum and groin.
Where does it hurt?
Why is a testicular cyst dangerous?
Experts claim that the growth of a testicular or epididymal cyst is very slow and does not cause any disorders or decrease in sexual activity or reproductive function in men. However, this disease is dangerous because pathogenic microbes and bacteria can penetrate into the contents of the cyst, which inevitably causes inflammation. With significant sizes of the testicular cyst or epididymal cyst, the scrotum is stretched, and with trauma to the scrotum, a rupture of the cyst is possible. The degeneration of benign cystic formations into malignant ones is also possible.
It should also be borne in mind that the consequences of a testicular cyst (provided that it is bilateral) result in male infertility.
Testicular cyst diagnosis
The diagnosis of a testicular cyst, as well as a cyst of the epididymis, is made on the basis of anamnesis, physical examination (palpation) and the results of an ultrasound examination (US).
Since the symptoms of this disease are non-specific, and palpation “blindly” does not provide
A complete picture of pathological changes, then ultrasound has become the main method for diagnosing testicular cysts. Ultrasound allows you to determine the exact location and size of the cyst, as well as distinguish it from hydrocele, hernia, testicular tumor and varicose veins of the spermatic cord (varicocele).
According to medical statistics, among all patients who, for one reason or another, undergo an ultrasound examination of the scrotum, testicular cysts are detected in almost every third adult man.

Treatment of testicular cysts
There are no medications for the treatment of testicular cysts (not complicated by inflammation), and in clinical practice, a patient with this diagnosis must choose either removal of the testicular cyst (or removal of the epididymis cyst) or sclerotherapy. In rare cases, a puncture method for treating testicular cysts is used.
Removal of a testicular cyst, according to doctors, is a time-tested and very reliable way to get rid of this pathology. Surgery for a testicular cyst is performed under local or general anesthesia: the scrotum membrane is cut over the cyst, the cyst is enucleated and the wound is sutured layer by layer. A gauze bandage, ice, and a supporting bandage (suspensory) are applied to the scrotum. To prevent postoperative inflammation, antibiotics are prescribed and physical activity is limited for two weeks. By the way, before surgery for a testicular cyst, doctors warn patients about the likelihood of their infertility in the future.
In addition to open surgery, laparoscopy is used to remove testicular cysts, as well as to remove epididymal cysts, which is much less traumatic, shorter, and less risky in terms of developing postoperative complications.
Sclerotherapy is an alternative to removal of testicular cysts, but less effective. During sclerotherapy, the contents of the cyst are removed from the cavity using a syringe and a special chemical compound is injected instead. As a result of the chemical reaction, the tissues lining the inner walls of the cyst are destroyed, and the walls become sclerotic, that is, “glued” together. In this way, the spermatic cord can be damaged, which causes male infertility.
The puncture method of treating testicular cysts differs from sclerotherapy in that after removing fluid from the cyst cavity, nothing is injected there. Despite the simplicity of the procedure, the effect of its implementation is temporary, since there is a high probability of repeated refilling of the cyst with serous fluid. In addition, according to doctors, each subsequent puncture poses a serious threat of damage to the testicle and epididymis.
It should be noted that the treatment of epididymal cysts is similar to the treatment of testicular cysts - surgical excision of the cyst or sclerotherapy.
A testicular cyst in a child, which can appear in adolescent boys, can quite often disappear spontaneously after the end of puberty. However, experts recommend removing epididymal cysts larger than 1.5 cm.
Treatment of testicular cysts with folk remedies
Treatment of testicular cysts with folk remedies, given that there is no drug therapy for this disease, seems quite... problematic. However, there are two plants that can help in the fight against this pathology. These are Icelandic moss and kelp.
Icelandic moss (Cetraria islandica) contains a lot of iodine, and preparations based on it have antiseptic properties, for example, sodium usninate. And a decoction is prepared from dry lichen: 10 g of crushed plant is taken per 200 ml of boiling water, boiled for 5-10 minutes, infused for half an hour and taken 3 times a day, a third of a glass.
In addition to iodine, kelp (laminaria) contains a polysaccharide - alginic acid, which removes heavy metals and radionuclides from the body, and its derivative sodium alginate has pronounced antitumor properties. In addition, biologically active substances of kelp regulate fat metabolism in the body, suppressing the metabolism of plant sterols. This reduces the risk of the formation of all kinds of pathological accumulations in the skin and other tissues. And it is not for nothing that doctors recommend kelp to men with problems with the prostate gland, for example, prostatitis and prostate adenoma.
So, when diagnosed with a testicular cyst, the use of kelp is clearly not without meaning. It should be drunk once a day - before bed, mixing a teaspoon of powder or granules of seaweed in 100 ml of water.
