Inhibin B Test

Inhibin B is a gonadal hormone that provides insight into reproductive function in both men and women. As part of comprehensive health screening, this marker can help assess overall hormonal balance.

Inhibin B: what this test measures

This test measures the concentration of Inhibin B in your blood. In women, it is produced by developing ovarian follicles and reflects follicular activity. In men, it is produced by Sertoli cells in the testes and is associated with sperm production.

Inhibin B: why this value matters

Monitoring Inhibin B supports a proactive approach to reproductive and hormonal health. Combined with other markers, it can provide a comprehensive view of gonadal function and help guide wellness decisions.

Inhibin B: how the blood test works

Referral
No GP referral needed. After the order we arrange the referral through ZorgDomein, within one business day; orders after 17:00 or at the weekend start on the next business day. ZorgDomein emails a barcode, and that barcode is what the draw site needs.
The draw
A blood draw from a vein in the arm, at a partner laboratory's draw site. No home kit, no finger prick.

Inhibin B: how to prepare

  1. Preferably fasting

    Recommended

    Coming fasting gives a slightly cleaner value, but it is not required. If it suits you, eat nothing from 22:00 the evening before and drink only water.

  • Water is always fine. Drink as usual beforehand, it makes the draw easier.
  • Take your usual medication, unless your own doctor told you otherwise.

Inhibin B: when is testing worthwhile?

Testing may be recommended when evaluating fertility concerns, assessing ovarian reserve, investigating unexplained infertility, or monitoring testicular function. Your healthcare provider can advise on optimal testing timing.

Inhibin B: symptoms of a high or low value

Low Levels

Some people with low Inhibin B may experience fertility challenges. In women, this could suggest reduced ovarian reserve. In men, low levels may be associated with decreased sperm production or testicular dysfunction.

High Levels

Elevated Inhibin B levels are not typically associated with specific symptoms in healthy individuals. However, markedly high levels may sometimes be associated with certain gonadal tumours and should be evaluated by a healthcare provider.

Inhibin B: what to do about an abnormal value

Male

If Low

Low inhibin B may indicate reduced testicular function. Consider fertility evaluation.

If High

High inhibin B is generally not concerning in men.

Female

If Low

Low inhibin B may indicate diminished ovarian reserve. Consider fertility consultation.

If High

High inhibin B may indicate good follicular development or a granulosa cell tumour.

Inhibin B: lifestyle and this value

Maintaining a healthy weight, managing stress, and avoiding smoking may support reproductive health and gonadal function. Regular check-ups with a healthcare provider can help monitor fertility markers over time.

Inhibin B: frequently asked questions

What does Inhibin B tell us about fertility?

In women, Inhibin B reflects ovarian follicle activity and may indicate ovarian reserve. In men, it is associated with Sertoli cell function and sperm production capacity.

When during the menstrual cycle should Inhibin B be tested?

For women, Inhibin B is typically tested in the early follicular phase of the menstrual cycle. Your healthcare provider will advise on the best timing.

Can Inhibin B levels change over time?

Yes, Inhibin B levels typically decline with age in both men and women. In women, this decline may accelerate as ovarian reserve diminishes approaching menopause.
