What's this test for?
This test is ideal if you're trying to conceive and want to check your fertility health, experiencing irregular periods, or concerned about reproductive function. It measures Inhibin B, a hormone that indicates ovarian reserve in women and sperm production in men, helping identify potential fertility issues. Many people use this test when planning a family or investigating why conception has been challenging.
How should I prepare for this test?
For women, this test is typically done on day 3 of your menstrual cycle for the most accurate assessment of ovarian reserve, though your doctor may recommend different timing based on your situation. No fasting is required for this test. Men can have this test done at any time. Bring a valid photo ID and your test order to the lab.
What's included in this test?
This test measures Inhibin B. This hormone is a key marker of reproductive health - in women, it reflects the number and quality of eggs remaining in the ovaries (ovarian reserve), while in men, it indicates how well the testicles are producing sperm. Lower levels may suggest diminished fertility potential or reproductive challenges, making it valuable for anyone evaluating their ability to conceive.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your Inhibin B levels mean for your fertility and reproductive health. These notes include personalized recommendations like when to consult a fertility specialist, lifestyle changes that support reproductive health, or whether additional hormone testing may be helpful. You'll also get the standard lab report and can track your hormone levels over time using our trends feature to monitor your reproductive health journey.
When will I get my results?
You can typically expect your Inhibin B test results within 3-5 business days after your blood sample is collected at the lab. Results are delivered securely online through your private account, along with easy-to-understand doctor notes. If results are needed urgently, contact customer support to check if expedited processing is available.
Who should consider getting this test?
This test is valuable for women over 35 planning pregnancy, anyone experiencing difficulty conceiving after 6-12 months of trying, or those with irregular or absent periods. It's also important for men with low sperm count or fertility concerns, and anyone considering egg or sperm freezing who wants to understand their reproductive timeline. People with a family history of early menopause may also benefit from this test.
What symptoms indicate I may need this test?
Women may need this test if experiencing irregular or absent periods, shorter menstrual cycles, difficulty getting pregnant, or symptoms of early menopause like hot flashes. Men might consider it if dealing with low libido, erectile dysfunction, infertility issues, or concerns about sperm production. This test is also useful if you simply want a proactive assessment of your reproductive health before trying to conceive.
How can I naturally support my reproductive health?
Maintaining a healthy weight is crucial, as both being overweight and underweight can affect reproductive hormones. Eat a balanced diet rich in antioxidants, omega-3 fatty acids, and folate from leafy greens, berries, fish, and nuts. Manage stress through regular exercise, adequate sleep, and relaxation techniques, as chronic stress can impact fertility hormones. Avoid smoking and excessive alcohol, which can significantly reduce fertility in both men and women.
What is Inhibin B and why does it matter?
Inhibin B is a hormone produced by the ovaries in women and the testicles in men that plays a key role in reproductive function. In women, it's one of the best indicators of ovarian reserve - essentially how many viable eggs remain - which naturally declines with age. In men, it reflects the health of sperm-producing cells and is closely linked to sperm count and quality. Low levels can signal diminished fertility potential in both sexes.
What does low Inhibin B mean?
Low Inhibin B in women typically indicates diminished ovarian reserve, meaning fewer eggs are available for conception, which is common as women approach their late 30s and 40s. In men, low levels suggest impaired sperm production or testicular dysfunction, which can contribute to male infertility. Low results don't mean pregnancy is impossible, but they do suggest it may be more challenging and that consulting a fertility specialist could be beneficial for personalized guidance and treatment options.
How often should I retest my Inhibin B levels?
If you're actively trying to conceive or undergoing fertility treatment, your doctor may recommend retesting every 3-6 months to monitor changes in ovarian reserve or testicular function. For women approaching their late 30s who want to track their fertility window, annual testing can help with family planning decisions. If your initial results are normal and you're not actively trying to conceive, retesting every 1-2 years provides a good baseline for reproductive health monitoring.

What this means
Your Inhibin B levels are slightly below the optimal range, which may indicate diminished ovarian reserve in women or reduced sperm production in men.
