Do you have low-T? Test yourself with a questionnaire

 

Questionnaires are used as part of the clinical diagnosis of testosterone deficiency, in addition to blood testing of testosterone levels.
 
The most widely researched and accepted questionnaires are the Androgen Deficiency in the Aging Male (ADAM) [1] and the Aging Male Symptoms (AMS) Rating Scale.[2]
 
The questionnaires mentioned here can be found on the page "Low-T questionnaires".
 
You can check yourself with the interactive Aging Male Symptoms (AMS) quiz, which will give you your AMS score immediately, as well as advice on what to do.
 
 

Androgen Deficiency in the Aging Male (ADAM) questionnaire

The ADAM (figure 1) is a self-administered 10 item questionnaire which is answered by yes/no.[1] Answering “yes” to the 2 items related to sexual function of any 3 other of the remaining 7 items provides an indication of prevalent hypogonadism. 
 
More recently, the standard ADAM questionnaire tool has been modified by adding weight to the answers, in order to provide information about the severity/frequency of the symptoms/signs of hypogonadism.[3] This qADAM questionnaire (figure 2) consists the same 10 questions as in the original ADAM questionnaire, but has "yes" and "no" replaced by a scale of 1–5, in which 5 represents the absence of a given symptom and 1 represents maximal symptoms. All questions are weighted equally. The summation of responses yields a total qADAM score between 10 and 50, with 10 being most symptomatic and 50 being least symptomatic. Because the responses are quantified it is supposed to be more useful in assessing results of testosterone therapy over time.[3]
 

Aging Male Symptoms (AMS) questionnaire

The AMS (figure 3) is also a self administered questionnaire designed to assess the symptoms of aging in males, to evaluate quality of life over time, and to measure effects of testosterone therapy.[2, 4, 5] Subjects rate symptoms from none (0) to extremely severe (5) for 17 items in 3 domains: psychological (5 items), somatic (7 items), and sexual (5 items). Total scores range from 17 (minimum) to 85 (maximum).

Important to know about questionnaires

Due to its simplicity, the standard ADAM is more widely used in clinical practice while the AMS and qADAM are primarily employed as a research tools. Both have a high degree of sensitivity (i.e. are good at detecting presence of symptoms/signs) but both also perform poorly in regard to specificity (i.e. the detected symptoms/signs can be caused by factors other than testosterone deficiency).[6, 7] The same applies to other questionnaires. Therefore, questionnaires on their own are not good diagnostic tools for testosterone deficiency, and cannot replace blood testing of testosterone levels.[8, 9] This is why most clinical guidelines require that questionnaire results be combined with blood testing for testosterone levels for diagnosis.[10, 11]
 
However, questionnaires are useful for screening and giving an indication of a possible prevailing sub-optimal testosterone level, and prominent clinicians and medical researchers emphasize the primacy of symptoms for the diagnosis of testosterone deficiency.[12] They are also a helpful tool to “break-the-ice” at the initial doctor visit. Questionnaires that provide a degree rating of symptoms (like qADAM and ASM) can also be used to monitor treatment effectiveness of testosterone therapy.[3, 13]
