Overview

The Inhibin B test is a blood test used to measure the levels of inhibin B hormone in the body. It is used to evaluate the function of the ovaries and testes, as inhibin B is produced by cells in these organs. The test is performed by drawing blood from a vein in the arm, and the results can help diagnose and monitor conditions such as infertility, polycystic ovary syndrome, and testicular cancer.

Who should do this test?

Men with suspected infertility: Inhibin B levels are a useful marker for assessing sperm production and testicular function in men with suspected infertility. A low level of inhibin B may indicate a problem with sperm production, which can help guide appropriate treatment options.

Women with suspected ovarian dysfunction: Inhibin B levels are also used to assess ovarian function in women. A high level of inhibin B may indicate the presence of an ovarian tumor, while a low level may suggest diminished ovarian reserve or premature ovarian failure.

Children with suspected gonadal dysfunction: Inhibin B levels can also be used to assess gonadal function in children with suspected disorders of sex development or delayed puberty. Low levels of inhibin B may indicate a problem with testicular or ovarian function, which can help guide appropriate diagnostic and treatment options.

What to do if the test is abnormal?

The first step is to consult with your physician or a specialist in reproductive endocrinology. They will review your medical history and the results of the inhibin B test to determine the cause of abnormal results.

Depending on the underlying condition, your healthcare provider may recommend additional tests or treatments. For example, if the abnormal results are due to ovarian dysfunction, they may recommend hormone replacement therapy or other medications to regulate hormone levels.

In some cases, lifestyle changes such as weight loss or stress reduction may be recommended to improve fertility outcomes. Your healthcare provider can provide guidance on the best approach for your individual situation based on your medical history and test results.
