Self-Test for Testosterone Deficiency in Men
The AMS Questionnaire ("Aging Males’ Symptoms Scale") is a scientifically developed self-test for assessing age-related symptoms in men. In particular, it serves to evaluate possible complaints that could be associated with a decreasing testosterone level. The test is easy to perform, standardized, and globally recognized – both in medical practice and for personal self-assessment at home.
With increasing age, a man's hormone balance can change. The AMS questionnaire helps to systematically record and objectify the symptoms that occur, making it a valuable tool for preventive healthcare.
What exactly does the AMS questionnaire measure?
The AMS questionnaire consists of 17 questions related to three central areas of life:
1. Psychological Symptoms
These include, among others, inner restlessness, irritability, nervousness, mood swings, or concentration problems.
2. Physical Complaints
These include chronic fatigue, sleep disturbances, muscle or joint pain, increased sweating, and decreased performance.
3. Sexual Changes
These can include loss of libido, erectile dysfunction, or decreased sexual desire.
Each question is rated on a scale from 1 (no symptoms) to 5 (very severe). The sum results in a score that indicates whether the symptoms are mild, moderate, or severe.
Who is the AMS test for?
The AMS questionnaire is primarily aimed at men aged 35 to 40 and older. At this age, many men begin to experience a slow decline in testosterone levels, which can manifest itself in many different ways.
The test is particularly helpful for men who
- frequently feel exhausted or weak
- suffer from loss of libido or erectile dysfunction
- experience problems with motivation or concentration
- experience mood swings or irritability
- are physically less resilient than before
However, the AMS test does not replace a medical diagnosis, but it offers a first, structured assessment of whether a hormonal cause for the existing complaints is plausible.
Importance for Men's Health
Untreated hormone deficiency can have significant long-term effects on health and quality of life – such as an increase in abdominal fat, muscle loss, osteoporosis, burnout-like states, or depressive moods. The AMS questionnaire helps to identify these connections early and address them specifically.
In combination with a blood test of the hormone profile (testosterone, free testosterone, SHBG, LH), a meaningful picture emerges for possible further therapy or lifestyle optimization.

Conclusion
The AMS questionnaire is an established tool for the early detection of symptoms associated with age-related hormone decline in men. It is easy to perform, provides valuable insights for further health planning, and can help to better classify physical and psychological complaints.
For men who want to take a more conscious approach to their health, the AMS test is a meaningful starting point and a possible guide for the next step: a well-founded diagnosis and targeted therapy.
