Testosterone replacement therapy may be suitable for men of any age with low or borderline low testosterone levels who exhibit signs and symptoms of hypogonadism and for whom contraindications to therapy have been medically ruled out.

Testosterone replacement therapy (TRT) offers a number of potential benefits, particularly for men with clinically diagnosed testosterone deficiency. It is important to emphasize that TRT should only be used in cases of diagnosed testosterone deficiency and under medical supervision. Potential key benefits include:

1. Improved libido and sexual function: One of the most common effects of testosterone deficiency is a decrease in libido or sexual desire. TRT can help improve sexual desire and erectile function, which can lead to a more satisfying sex life.
‍
2. Increased energy and overall well-being: Low testosterone levels can lead to fatigue, lack of energy, and a general feeling of malaise. Many men report increased energy and an improved quality of life after starting TRT.
‍
3. Improvement of muscle mass and body composition: Testosterone plays a key role in building and maintaining muscle mass. TRT can increase muscle mass and reduce body fat percentage, especially when combined with regular exercise.
‍
4. Positive effects on bone density: Testosterone contributes to bone health, and a deficiency can lead to a decrease in bone density. TRT can help increase bone density and reduce the risk of osteoporosis and fractures.
‍
5. Improved mood and mental clarity: Testosterone deficiency can lead to mood swings, irritability, and difficulty concentrating. Normalizing testosterone levels can alleviate these symptoms, contributing to better mental clarity and a more stable mood.

6. Possible positive effects on the cardiovascular system: Some studies suggest that well-monitored TRT may have positive effects on the cardiovascular system, although research in this area is not yet complete.

The costs for potential testosterone replacement therapy are comprised of various components.

Medication (via pharmacies): with a doctor's prescription, approx. €20–70 per month
