Medical experts warn of rising testosterone deficiency inquiries and hormonal risks

An increasing number of men are seeking medical evaluations for testosterone deficiency, though medical experts warn that true deficiency is extremely rare among healthy men. Mikael Lehtihet, an associate professor of endocrinology and senior physician at Karolinska Institutet, states that low testosterone levels are often misunderstood and frequently linked to underlying conditions such as weight gain or type 2 diabetes rather than a biological "male menopause."

Lehtihet emphasizes that a diagnosis requires both repeated low values and clear symptoms, most notably a significant disappearance of sexual desire. He also warns against the self-administration of high doses of testosterone, noting that such practices carry severe risks, including cardiovascular disease, hypertension, and kidney damage.

Research also points to environmental factors as potential contributors to hormonal disruption. The European Chemicals Agency (ECHA) has identified various bisphenols, including BPA, as reproductive toxins and endocrine disruptors. While the EU has begun phasing out BPA in food-contact materials, some products may remain on the market until 2028. Additionally, ECHA has warned that substitutes like BPS may also affect male hormonal and reproductive systems.
