Long-term buprenorphine therapy saves lives. For many patients in recovery from opioid use disorder, Suboxone is the foundation of a stable, functional life. But there is a side effect that does not get discussed enough in clinical settings: opioid-induced hypogonadism, or low testosterone caused by prolonged opioid exposure — including buprenorphine.

How it happens

All opioids, including buprenorphine, interact with receptors in the hypothalamus and pituitary gland that regulate hormone production. Over time, this suppresses the signal that tells the testes to produce testosterone. The result is chronically low testosterone levels that can persist for months or years — often without the patient or provider connecting the dots.

What it looks like

The symptoms of low testosterone overlap significantly with other common experiences in recovery: fatigue, low motivation, depression, weight gain, reduced libido, and difficulty building or maintaining muscle. Because these symptoms are so common in early and mid-recovery, they are frequently attributed to the recovery process itself rather than a correctable hormonal imbalance.

Why it matters

Untreated low testosterone can undermine recovery. Fatigue and depression are two of the most cited reasons patients disengage from treatment or relapse. When a hormonal cause is driving those symptoms and goes unaddressed, patients are working harder than they need to against something that is clinically manageable.

What can be done

Testing is straightforward — a morning testosterone panel alongside LH, FSH, and SHBG gives a clear picture of whether the hypothalamic-pituitary-gonadal axis is suppressed. Treatment options depend on the patient's goals, including whether fertility preservation matters, and may include testosterone replacement therapy, clomiphene, or enclomiphene.

At Dawn Gadon Wellness, patients on long-term MAT are routinely screened for hormonal imbalances as part of a whole-person approach to care. Recovery is the foundation — but it should not come at the cost of your quality of life.

If you are on Suboxone and experiencing fatigue, low mood, or reduced libido, ask about getting your testosterone levels checked. It is a simple test that could change how you feel significantly.
