Treatment for Andropause (Late-Onset Hypogonadism)
Diagnosis and Assessment
- The European Association of Urology recommends that diagnosis of hypogonadism should only be made in men with consistent symptoms and unequivocally low serum testosterone levels 2
- The diagnosis requires morning total testosterone measurements on at least two separate occasions, as recommended by the European Urology guidelines 1
- Clinical evaluation should include assessment of symptoms such as decreased libido, erectile dysfunction, fatigue, and decreased vitality, as suggested by the New England Journal of Medicine 3
- Evaluation for potential causes, including pituitary disorders and medications affecting the HPG axis, is necessary, according to the European Urology guidelines 1
- Physical examination, including BMI and waist circumference, is an essential part of the clinical evaluation, as recommended by the European Urology guidelines 1
Treatment Recommendations
- The European Urology guidelines recommend weight loss through low-calorie diets to reverse obesity-associated secondary hypogonadism 1
- Physical activity shows benefits, with results correlating to exercise duration and weight loss, as suggested by the European Urology guidelines 1
- These interventions may increase testosterone levels by 1-2 nmol/L, according to the European Urology guidelines 1
- Testosterone replacement therapy is indicated for men with symptomatic hypogonadism, consistently low testosterone levels, and symptoms affecting quality of life, as recommended by the Annals of Internal Medicine 2
Contraindications to Testosterone Therapy
- Absolute contraindications to testosterone therapy include active or treated male breast cancer, as recommended by the European Urology guidelines 1
- Planning fertility in the near term is also a contraindication, according to the European Urology guidelines 1
Monitoring During Treatment
- Regular follow-up with a standardized monitoring plan, including evaluation of symptoms, adverse effects, and compliance, is necessary, as suggested by the New England Journal of Medicine 3
Expected Benefits and Limitations
- Benefits of testosterone therapy include improved sexual functioning and quality of life, with small but significant improvements, as reported by the Annals of Internal Medicine 2, 4
- Increased muscle mass and strength are also benefits of testosterone therapy, according to the New England Journal of Medicine 3
- Improved bone mineral density is another benefit, as suggested by the New England Journal of Medicine 3
- However, there is limited or no benefit for physical functioning, depressive symptoms, energy and vitality, cognition, weight reduction, or cardiometabolic status, as reported by the Annals of Internal Medicine 2, 4 and the European Urology guidelines 1
Important Considerations
- Testosterone therapy should not be used in eugonadal men, as recommended by the European Urology guidelines 1
- Fertility concerns must be addressed before initiating therapy, according to the European Urology guidelines 1
- Long-term efficacy and safety data are limited, particularly for cardiovascular outcomes and prostate cancer risk, as reported by the Annals of Internal Medicine 2, 4
- Combining lifestyle modifications with TRT may yield better outcomes in symptomatic patients, as suggested by the European Urology guidelines 1
