Do you feel like you have passed your peak? While men do not experience an abrupt decline in sex hormones like women do, many men start to experience bothersome symptoms as they get older, or gain body weight (regardless of age).

The Ageing Males' Symptoms scale (AMS) is the most commonly used scale in many countries worldwide to measure health-related quality of life and symptoms in ageing males.5 It is a self-administered questionnaire that will help you:6

1) Assess symptoms of ageing.
2) Evaluate the severity of your symptoms over time.
3) Measure changes in symptoms before and after testosterone therapy.

Don't forget to print out your results and take them to your doctor on your next visit.

The AMS questionnaire itself (or any other questionnaire) does not constitute a test or diagnosis of hypogonadism (also known as testosterone deficiency). A diagnosis of hypogonadism is based on symptoms that are indicative of testosterone deficiency (the AMS questionnaire can be used for symptom evaluation), combined with low testosterone levels as detected by mandatory blood testing.1-4

The AMS scale is comparable to other scales for ageing males or screening instruments for testosterone deficiency, and thus can be used to identify symptomatic men who should be investigated further with a blood test of testosterone.7 It is commonly used as part of the diagnosis of hypogonadism, which requires the presence of characteristic symptoms and signs in combination with low serum levels of testosterone.2,8,9,10

The AMS scale is also a valuable tool to measure effects of testosterone treatment on symptom relief over time.14,15

In addition, the AMS scale can help you to “break the ice” at your first doctor visit, as it specifically asks for symptoms that you would not otherwise spell out, but that have an important impact on your wellbeing and quality of life.

On the last page of the questionnaire you will get the option to print out your AMS score. We suggest you do, and bring it to your doctor.
