The exact cause of this tumor is not known. Changes (mutations) in genes may play a role.
Sertoli-Leydig tumors occur most often in young women 20 to 30 years old. But the tumor can occur at any age.
The Sertoli cells are normally located in the male reproductive glands (the testes). They feed sperm cells. The Leydig cells, also located in the testes, release a male sex hormone called testosterone.
These cells are also found in a woman's ovaries, and in very rare cases lead to cancer. A Sertoli-Leydig cell tumor is a cancer that starts in the female ovaries, usually in younger women. The cancer cells release a male sex hormone. As a result, the woman may develop symptoms such as:
A deep voice
Loss in breast size
Stopping of menstrual periods
Pain in the lower belly (pelvic area) is another symptom. It is usually due to the tumor pressing on nearby structures
Exams and Tests
The doctor will perform a physical exam and a pelvic exam, and ask about your symptoms.
Tests will be ordered to check the levels of female and male hormones, including testosterone.
An ultrasound or another imaging test will likely be done to find out where the tumor is and its size and shape.
