What is Pea size lump on side of testicle?

A pea-sized lump on the side of the testicle can be a cause for concern and should be evaluated by a healthcare professional, such as a urologist. Several conditions can cause such a lump, some of which may require treatment. Here are some possible causes:

1. Epididymal Cyst: A small, fluid-filled sac that develops on the epididymis, a tube that carries sperm from the testicle to the vas deferens. Epididymal cysts are usually benign and painless, but they can sometimes cause discomfort or swelling.

2. Spermatocele: A benign cyst that forms in the testicle and contains sperm. Spermatoceles are typically painless and do not cause any symptoms, but they can sometimes cause a noticeable lump.

3. Varicocele: A condition in which the veins in the scrotum become enlarged and swollen. Varicoceles can cause a feeling of heaviness or discomfort in the scrotum, and they can sometimes be seen as a bluish or purplish discoloration of the skin.

4. Inguinal Hernia: A weakness in the abdominal wall that allows a portion of the intestine to protrude into the scrotum. Inguinal hernias can cause a visible bulge or lump in the scrotum, and they can sometimes be painful or uncomfortable.

5. Testicular Cancer: In rare cases, a pea-sized lump on the side of the testicle could be a sign of testicular cancer. Testicular cancer typically presents as a painless, firm lump in the testicle, but it can sometimes cause other symptoms such as swelling, pain, or a feeling of heaviness in the scrotum.

It is important to see a healthcare professional for an accurate diagnosis and appropriate treatment. The doctor may perform a physical examination, order imaging tests such as an ultrasound, or recommend further tests to determine the cause of the lump. Depending on the underlying condition, treatment options may include observation, medication, or surgical intervention. Self-examination of the testicles can help in early detection of any abnormalities and should be done regularly.
