What Is an Inhibin B Test?
The Inhibin B test measures the level of inhibin B, a hormone produced by the reproductive organs, in a blood sample. In women, inhibin B is made by the ovaries; in men, it is produced by the testicles. Doctors order this Inhibin B hormone test to assess fertility, evaluate ovarian reserve, or investigate certain ovarian tumours. It is also called Serum Inhibin B.
What Does an Inhibin B Test Measure?
The test measures a single hormone, inhibin B, which plays a key role in reproduction. The table below explains what this hormone does and why its level matters.
| Parameter | What It Reflects |
|---|---|
| Inhibin B (women) | Ovarian reserve — the number and quality of eggs remaining in the ovaries |
| Inhibin B (men) | Sertoli cell function — the testicular cells that support sperm production |
Inhibin B also helps regulate follicle-stimulating hormone (FSH), a pituitary hormone that drives egg and sperm development. When inhibin B levels fall, FSH tends to rise, which can signal a decline in reproductive function.
Why Is an Inhibin B Test Done?
Doctors request this test for a range of reproductive and hormonal concerns. Understanding the common reasons can help you feel more prepared.
Common Symptoms That May Require This Test
The following symptoms often prompt a doctor to order an Inhibin B test:
- Difficulty conceiving despite regular, unprotected intercourse
- Irregular or absent menstrual cycles
- Low sperm count on a semen analysis
- A pelvic mass was detected on ultrasound
- Abnormal vaginal bleeding, particularly in post-menopausal women
- Signs of early puberty in children
Conditions This Test Can Help Detect
This test can provide useful information about several conditions, including:
- Diminished ovarian reserve (a reduced number of eggs remaining)
- Impaired sperm production or testicular dysfunction
- Granulosa cell tumours of the ovary
- Mucinous epithelial ovarian tumours
- Polycystic ovary syndrome (PCOS)
- Precocious puberty (early puberty) in girls
- Klinefelter's syndrome or other causes of hypogonadism in men
Inhibin B Test for Chronic Disease Monitoring
For patients already diagnosed with granulosa cell tumours of the ovary, inhibin B is a useful monitoring marker. Levels typically drop to very low or undetectable values shortly after surgery. A rise in inhibin B during follow-up may suggest residual disease or recurrence, making regular monitoring an important part of post-treatment care.
How to Prepare and What to Expect
Preparing for this test is straightforward. Here is everything you need to know before your appointment.
Do You Need to Fast?
No fasting is required for the Inhibin B hormone test. You may eat and drink normally before your sample is collected.
For women having the test as part of a fertility assessment, the timing of sample collection does matter. The early follicular phase of the menstrual cycle, typically days 2 to 5, is the preferred window for the most accurate results.
Practical Tips Before Your Test
A few simple steps can help ensure your sample is suitable for analysis:
- If you take high-dose biotin (vitamin B7) supplements, stop them at least 72 hours before the test, as biotin can interfere with the assay
- Tell your doctor about all medications, hormonal treatments, or fertility drugs you are currently taking
- Wear a short-sleeved or loose-fitting top so that your arm is easy to access
- Stay well hydrated; there is no restriction on water intake
Step-by-Step Procedure
The blood collection process is quick and causes minimal discomfort. Here is what to expect:
- A trained phlebotomist cleans the skin on your inner arm with an antiseptic wipe.
- An elastic band is placed around your upper arm to help the vein become more visible.
- A fine needle is gently inserted into the vein to draw a small blood sample.
- The needle is removed, and a cotton ball or small bandage is placed over the site.
- The blood is collected into a labelled tube and sealed securely.
- The sample is dispatched to the laboratory, where it is analysed using an enzyme-linked immunosorbent assay (ELISA) method.
Factors That Can Affect Accuracy
Certain factors may influence the reliability of your result:
- Timing of the test during the menstrual cycle (for premenopausal women)
- Hormonal medications and fertility drugs
- High-dose biotin supplement use
- Severe illness, recent surgery, or significant physical stress
- Haemolysed (damaged red blood cell) or lipaemic (high-fat) samples, which are not suitable for analysis
Understanding Your Inhibin B Test Results
Results should always be reviewed alongside your full medical history and other test findings. The table below outlines the general reference ranges used in most laboratories.
| Group | Reference Range | Unit |
|---|---|---|
| Adult males | under 100 | pg/mL |
| Females aged 13 to 41 years (follicular phase) | under 223 | pg/mL |
| Females aged 42 to 51 years (follicular phase) | under 108 | pg/mL |
| Post-menopausal women | Less than 5 | pg/mL |
| Male neonates (under 15 days) | 68 to 373 | pg/mL |
| Infant (15 days - 6 months) | 42-516 | pg/mL |
| Child (7 months - 7 years) | 24-300 | pg/mL |
| Males aged 8 to 30 years | 47 to 383 | pg/mL |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Some circumstances can alter how results are interpreted. Here are the key ones noted for this test:
Inhibin B levels shift throughout the menstrual cycle, so results in premenopausal women must be read in the context of cycle timing. Women on hormone replacement therapy (HRT) may show artificially elevated levels, as HRT can stimulate inhibin B production even after menopause.
How to Maintain Healthy Levels
These general wellness tips support overall reproductive health:
- Follow a balanced diet that includes antioxidant-rich foods such as fruits, vegetables, nuts, and whole grains
- Avoid smoking and limit alcohol consumption, as both can negatively affect fertility hormones
- If you are planning assisted reproduction, speak to a fertility specialist who can guide you on appropriate testing and timing

Frequently Asked Questions
The Inhibin B test is primarily used to evaluate fertility in both men and women. In women, it helps assess how many eggs remain in the ovaries. In men, it reflects how well the testicles are producing sperm. It is also used as a tumour marker for certain ovarian cancers, particularly granulosa cell tumours.
No, fasting is not required. You can eat and drink as normal before your blood sample is collected. The only preparation to keep in mind is stopping high-dose biotin supplements at least 72 hours before the test.
For fertility assessment, the preferred timing is during the early follicular phase of the menstrual cycle, ideally on day 3 but within days 2 to 5. Collecting the sample outside this window may make results harder to interpret accurately.
The Inhibin B hormone test is a recognised marker for adult-type granulosa cell tumours of the ovary. It is elevated in the vast majority of patients with this cancer. It also shows elevated levels in some mucinous epithelial ovarian tumours. The test is used both for initial investigation and for monitoring after treatment.
In men, low Inhibin B levels generally indicate reduced or absent sperm production and poor Sertoli cell function. The level correlates with sperm count, making it a useful non-invasive indicator during male infertility evaluation. Your doctor will assess this alongside a semen analysis and other hormone tests.
Yes. Hormonal medications and fertility drugs are known to alter inhibin B levels. High-dose biotin supplements can also interfere with the laboratory assay. Always inform your doctor about every supplement and medication you are taking before the test.
Because the sample is often sent to a specialist reference laboratory, results typically take 1 to 6 days. Your report will be shared digitally once it is ready. If you have not received your results within this period, contact your collection centre for an update.
