Arrhenoblastoma of ovary

Arrhenoblastoma of the ovary is an ovarian tumor that secretes testosterone .

Alternative Names

Stromal tumor; Gonadal stromal tumor; Sex cord tumor; Androblastoma

Causes, incidence, and risk factors

This is a rare tumor that accounts for less than 0.5% of all ovarian tumors. These tumors are found in women of all age groups, but are most common in young women.

Signs and tests

  • ultrasound of the ovaries
  • CT scan of pelvis and abdomen to look for tumor spread
  • blood tests to check levels of hormones which may be secreted by the tumor
  • Treatment

    Surgery is the main treatment. If the cancer has spread, chemotherapy or radiation therapy should be considered.

    Support groups

    The stress of illness can often be helped by joining a support group where members share common experiences and problems. See cancer - support group .

    Expectations (prognosis)

    The outcome of this disease depends on the extent of disease and the ability to completely remove the tumor with surgery. The overall 5-year survival rate is around 70-90%. Fortunately, arrhenoblastoma has a low chance of spreading (metastasis). If the tumor is detected early, the cure rate may be very good.


  • Masculinization as described above.
  • Surgical complications depending on the extent of surgery.
  • Spread of the tumor if it is not completely removed.
  • Calling your health care provider

    Call your health care provider if you are a woman experiencing signs of masculinization or if you feel a mass near your ovaries.


    There is no good screening test. Annual gynecological exams and early recognition of signs of masculinization are important in the detection of the disease.
