What exactly is male hypogonadism?
What exactly is male hypogonadism?
Hypogonadism in men is a condition in which the body does not produce enough testosterone. Hypogonadism can cause various symptoms such as low libido, fatigue, mood swings, and erectile dysfunction. The causes are diverse, but the following forms can generally be distinguished:
Primary hypogonadism: Primary hypogonadism occurs when the problem lies directly in the testicles. In this case, the testicles do not produce enough testosterone – regardless of signals from the brain. Possible causes include genetic factors (as in Klinefelter syndrome), physical damage (e.g., from injuries), or damage from chemotherapy and radiation therapy.
Secondary hypogonadism: In secondary hypogonadism, the problem lies in the pituitary gland or the hypothalamus – two glands in the brain that release hormones to regulate testosterone production in the testicles. Causes can include genetic abnormalities, tumors (e.g., a prolactinoma), infections, or certain chronic diseases.
Tertiary hypogonadism: Tertiary hypogonadism is an alternative term for a disorder of the hypothalamus that affects the pituitary gland and thus indirectly alters testosterone production in the testes. The causes are similar to those of secondary hypogonadism and include genetic disorders, tumors, and other diseases that affect the hypothalamus.
Functional hypogonadism: Functional hypogonadism refers to reduced testosterone production that is not caused by direct problems of the testicles, pituitary gland, or hypothalamus, but rather by external factors or lifestyle conditions. These include factors such as obesity, chronic stress, metabolic disorders, or long-term illnesses.

Testosterone replacement therapy (TRT)
For whom is testosterone replacement therapy suitable?
For whom is testosterone replacement therapy suitable?
Testosterone replacement therapy (TRT) may be suitable for men of any age with low or borderline low testosterone levels who have signs and symptoms of hypogonadism and for whom contraindications to therapy have been medically ruled out.
What are the benefits of testosterone replacement therapy?
What are the benefits of testosterone replacement therapy?
Testosterone replacement therapy (TRT) can offer 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.
Are there risks associated with testosterone replacement therapy?
Are there risks associated with testosterone replacement therapy?
As with any medical treatment, testosterone replacement therapy also carries potential risks – you should discuss with your doctor how these may apply to you before starting therapy in order to make an informed decision:
- Headache
- Hot flashes
- insomnia
- High blood pressure
- acne
- Emotional lability
- Skin irritation at the application site
- nervousness
- Temporary infertility during therapy
- Person-to-person transmission of the drug during testosterone gel therapy (e.g., to women, children)
In recent years, large-scale and highly regarded studies have generally ruled out significant side effects of testosterone replacement therapy, such as the development of prostate cancer or an increase in cardiovascular risk . Of course, you will receive detailed information about potential side effects during your initial consultation with your doctor.
How much does testosterone replacement therapy cost?
How much does testosterone replacement therapy cost?
The costs for potential testosterone therapy can vary depending on the doctor, the type of therapy, and individual circumstances. Generally, the following costs may arise when using Adon Health:
- Laboratory test (entry test)
The first lab test costs €99.90 .

An initial consultation takes place before any potential therapy, a first check-up appointment after about 4 weeks, and then usually every 3 months.
- Laboratory test (progress test)
A regular laboratory check is usually scheduled every 3 months.
The cost for this is €97.50 (including service fee) .

Treatment
Can I easily stop my TRT?
Can I easily stop my TRT?
You can stop TRT at any time. However, it is important that you do not stop TRT abruptly, but rather discuss the discontinuation of therapy with your treating physician.
How does the therapy work?
How does the therapy work?
In most cases, treatment with testosterone enanthate or testosterone gel is prescribed by a doctor if treatment is deemed necessary. Testosterone enanthate is injected weekly or bi-weekly, depending on the doctor's recommendation, while the testosterone gel is applied to the skin once daily. You will discuss the exact application with your doctor before starting treatment. Further instructions can be found in the package insert.
Can I increase the dosage of my medication?
Can I increase the dosage of my medication?
Dose adjustments should always be made only in consultation with your treating physician.
What happens if I can't use the medication for a while?
What happens if I can't use the medication for a while?
It's best to avoid interrupting the therapy. However, if you don't use the gel for a few days, it's not dangerous. Your testosterone levels will simply drop slightly without you having to worry about serious side effects.
What are the side effects of testosterone replacement therapy (TRT)?
What are the side effects of testosterone replacement therapy (TRT)?
Like any therapy, TRT has potential side effects. These include, among others:
- Increased red blood cell count (polycythemia) – This can increase the risk of thrombosis, which is why regular blood tests are important.
- Temporary reduction in fertility – TRT can inhibit the body's own testosterone production and sperm production. In many cases, this normalizes after discontinuing the therapy.
- Skin changes – Increased sebum production can lead to acne or oily skin.
- Hormonal fluctuations – Mood swings can occur, especially at the beginning of therapy.
- Gynecomastia (breast growth) – In rare cases, an imbalance between testosterone and estrogen can lead to an enlargement of breast tissue.
Previously feared side effects such as an increased risk of cardiovascular disease or prostate cancer could not be confirmed by large, high-level studies.
Nevertheless, medical supervision is essential to ensure that the therapy is safe and tailored to the individual.
What should I do in an emergency?
What should I do in an emergency?
Emergencies are very unlikely during TRT. However, should an unexpected medical emergency occur, please call emergency services immediately at 112 or go to an emergency room.
Could further tests be necessary in addition to the regular blood tests?
Could further tests be necessary in addition to the regular blood tests?
Depending on the results of the lab tests and your presentation of symptoms, further examinations may be necessary, some of which cannot be covered solely via telemedicine. This may require an appointment with your general practitioner, and possibly also with a specialist. Your doctor will discuss the next steps with you during your consultation.
Can the costs be covered by health insurance? If so, which ones?
Can the costs be covered by health insurance? If so, which ones?
Unfortunately, reimbursement by statutory health insurance (GKV) is not possible, as this is a purely private medical treatment.
Private health insurance (PKV) can generally cover part of the costs. However, this depends on the individual insurance contract, and coverage cannot be guaranteed.
Medical consultations are billed according to the German fee schedule for physicians (GOÄ). These fees, as well as any necessary medication, are generally reimbursable by private health insurance providers.
However, laboratory tests for home use cannot be reimbursed, as these are lifestyle tests that cannot be billed according to the German fee schedule for physicians (GOÄ).
For more detailed information, we recommend contacting your private health insurance company directly.
Can I deduct the costs of my treatment from my taxes?
Can I deduct the costs of my treatment from my taxes?
Yes. The costs for medical treatments, laboratory analyses, medications and accessories within the scope of a medically necessary therapy (e.g., in the case of diagnosed testosterone deficiency / hypogonadism) are generally considered extraordinary expenses according to § 33 EStG and are therefore tax deductible.
Whether the costs lead to an actual reimbursement in a given case depends on the so-called reasonable burden, which varies depending on income, marital status and number of children.
Tip: Keep all invoices and payment receipts (e.g., Adon invoices, doctor's invoices according to the German Fee Schedule for Physicians (GOÄ), pharmacy receipts) and include them in your tax return.
