The Association between Serum Testosterone and Hyperuricemia in Males

Area of Science:

• Endocrinology
• Rheumatology
• Men's Health

Background:

• Gout is a prevalent inflammatory condition predominantly affecting men.
• Hyperuricemia, characterized by elevated serum urate (SU) levels, is a key risk factor for gout.
• The relationship between testosterone levels and hyperuricemia requires further investigation.

Purpose of the Study:

• To investigate the association between serum total testosterone levels and hyperuricemia in adult men.
• To determine if lower testosterone levels correlate with increased SU levels.

Main Methods:

• Analysis of data from 1899 men, with measurements of serum testosterone and SU taken at enrollment.
• Primary endpoints defined as SU levels ≥ 7 mg/dL and ≥ 9 mg/dL.
• Statistical adjustments for covariates including age, BMI, creatinine, lipids, glucose, and blood pressure.

Main Results:

• Mean total testosterone levels were significantly lower in men with SU levels ≥ 7 mg/dL (470 ng/dL) and ≥ 9 mg/dL (425 ng/dL) compared to those with lower SU levels.
• Low testosterone (<400 ng/dL) was significantly associated with SU levels ≥ 7 mg/dL (HR: 1.182) and ≥ 9 mg/dL (HR: 1.905) after multivariable adjustment.
• These associations remained significant even after controlling for multiple health parameters.

Conclusions:

• Lower serum total testosterone levels may be an independent risk factor for hyperuricemia in men.
• This finding suggests a potential link between hormonal status and the development of conditions like gout.
• Further research is warranted to explore the underlying mechanisms and clinical implications.
