Leydig cell tumorTumor - Leydig cell; Testicular tumor - Leydig; Testicular neoplasm
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).
A testosterone test measures the amount of the male hormone, testosterone, in the blood. Both men and women produce this hormone. The test described...
The cause of this tumor is unknown. There are no known risk factors for this tumor. Unlike germ cell tumors of the testicles, this tumor does not seem to be linked to undescended testes .
Undescended testicle occurs when one or both testicles fail to move into the scrotum before birth.
Leydig cell tumors make up a very small number of all testicular tumors. They are most often found in men between 30 and 60 years of age. This tumor is not common in children before puberty, but it may cause early puberty .
Puberty is the time during which a person's sexual and physical characteristics mature. Precocious puberty is when these body changes happen earlier...
There may be no symptoms.
When symptoms do occur, they can include:
- Discomfort or pain in the testicle
- Enlargement of a testicle or change in the way it feels
- Excess growth of breast tissue ( gynecomastia ) -- however, this can occur normally in adolescent boys who do not have testicular cancer
- Heaviness in the scrotum
- Lump or swelling in either testicle
- Pain in the lower abdomen or back
- Not able to father children (infertility)
Symptoms in other parts of the body, such as the lungs, abdomen, pelvis, back, or brain may also occur if the cancer has spread.
Exams and Tests
A physical examination typically reveals a firm lump in one of the testicles. When the health care provider holds a flashlight up to the scrotum, the light does not pass through the lump. This test is called transillumination .
Transillumination is the shining of a light through a body area or organ to check for abnormalities.
Other tests include:
Blood tests for tumor markers:
(AFP), human chorionic gonadotropin (beta HCG), and
Alpha fetoprotein (AFP) is a protein produced by the liver and yolk sac of a developing baby during pregnancy. AFP levels go down soon after birth. ...
- CT scan of the chest, abdomen and pelvis to check if the cancer has spread
- Ultrasound of the scrotum
An examination of the tissue is usually done after the entire testicle is surgically removed (orchiectomy).
Treatment of a Leydig cell tumor depends on its stage.
- Stage I cancer has not spread beyond the testicle.
- Stage II cancer has spread to lymph nodes in the abdomen.
- Stage III cancer has spread beyond the lymph nodes (possibly as far as the liver, lungs, or brain).
Surgery is done to remove the testicle (orchiectomy). Nearby lymph nodes may also be removed (lymphadenectomy).
Chemotherapy may be used to treat this tumor. As Leydig cell tumors are rare, these treatments have not been studied as much as treatments for other, more common testicular cancers.
The term chemotherapy is used to describe cancer-killing drugs. Chemotherapy may be used to:Cure the cancerShrink the cancerPrevent the cancer from ...

Testicular cancer is one of the most treatable and curable cancers. Outlook is worse if the tumor is not found early.
The cancer may spread to other parts of the body. The most common sites include the:
- Retroperitoneal area (the area near the kidneys behind the other organs in the belly area)
Complications of surgery can include:
- Bleeding and infection
- Infertility (if both testicles are removed)
If you are of childbearing age, ask your provider about methods to save your sperm for use at a later date.
When to Contact a Medical Professional
Call your provider if you have symptoms of testicular cancer.
Performing testicular self-examination (TSE) each month may help detect testicular cancer at an early stage, before it spreads. Finding testicular cancer early is important for successful treatment and survival.
Testicular self-examination (TSE)
Testicular self-exam is an examination of the testicles that you do on yourself.
