Intro
In this module, you will learn how testosterone deficiency affects the body, how common it is, and which risk factors contribute to it. You will also learn about the various causes – from age-related changes to medical and lifestyle-related influences. Finally, the three main forms of hypogonadism will be explained so that you understand the differences and can better classify testosterone deficiency.
Symptoms of testosterone deficiency
Symptoms of testosterone deficiency can be varied and often distressing. In this video, Professor Dr. Zitzmann uses a patient example to illustrate typical signs of a deficiency and how it affects the body. You'll learn how symptoms such as fatigue, lack of motivation, reduced muscle mass, and mood swings are related to low testosterone levels and what long-term effects a deficiency can have on overall health.
Frequency of testosterone deficiency
Testosterone deficiency is more common than many people realize and affects certain groups more frequently. In this video, Professor Dr. Zitzmann explains just how widespread testosterone deficiency actually is and which factors can increase the risk. You'll learn which age groups are particularly affected and which lifestyle or health factors influence testosterone levels.
Causes of testosterone deficiency
The causes of testosterone deficiency can be varied and are often linked to complex biological processes. This video clearly explains why a testosterone deficiency can occur in the body. You will learn about the different medical causes, such as hormonal changes with age, genetic factors, chronic illnesses, and lifestyle influences that can affect testosterone levels. Professor Dr. Zitzmann guides you through the background of these causes and shows how they affect hormone production.
Primary, secondary and functional hypogonadism
Primary, secondary, and functional hypogonadism—don't worry if these terms are new to you. In this video, Professor Dr. Zitzmann explains these different forms of hypogonadism in an easy-to-understand way and how they differ from one another. You'll learn how primary hypogonadism is directly caused by a malfunction of the testicles, while secondary hypogonadism originates in the brain, specifically in the pituitary gland or hypothalamus. Functional hypogonadism, which can be caused by factors such as stress or certain lifestyle habits, is also discussed.

Intro
In this module, you'll learn how to diagnose testosterone deficiency. You'll discover which tests and examinations are necessary and how a sample patient is guided through the diagnostic process. We'll also introduce you to the AMS questionnaire – a helpful tool for initial assessment. By the end, you'll know exactly what steps are involved in diagnosis and how to interpret the results.
The diagnostic process
What exactly does the diagnostic process for a possible testosterone deficiency entail? This video explains in detail the steps involved, from blood draws and consultations to the investigation of the underlying causes. First, it explains when and how the blood sample is taken to obtain the most accurate results. Then, you'll learn how the results are discussed and analyzed during the consultation. This includes investigating the causes to identify individual factors and potential triggers for a testosterone deficiency, thus enabling targeted treatment.
The diagnostic process using a patient as an example
In this video, Prof. Dr. Zitzmann uses a sample patient to demonstrate the diagnostic process explained earlier. You will see how the steps – from the initial blood draw and detailed discussion of the results to the analysis of the underlying causes – are implemented in practice. This case study illustrates how individualized the diagnosis is and which specific factors are considered when assessing testosterone deficiency in order to prepare for targeted therapy.
The AMS questionnaire
The AMS questionnaire is a simple and effective tool for assessing whether a testosterone deficiency might be present, based on typical symptoms. In just a few minutes, symptoms such as fatigue, mood swings, or physical changes that could indicate low testosterone levels can be recorded. You can download the questionnaire using the following link and easily complete it yourself: AMS Questionnaire.
