What is testosterone and what effects does it have?
Testosterone is a steroid hormone that is primarily produced in the testicles. Smaller amounts are also produced in the adrenal glands. It is considered the most important male sex hormone, but it also plays a role in women at lower concentrations.
Main functions of testosterone:
-
Development of male sexual characteristics (voice, beard growth, muscle mass)
-
Libido and fertility
-
Bone strength and muscle growth
-
Metabolic regulation
-
Mood, energy & mental health
👉 Testosterone therefore affects not only the body but also your mental well-being. You can find out more about personalized healthcare solutions on the MyBodyX homepage.
Testosterone levels in men – why they matter
A stable testosterone level is crucial for vitality and performance. However, the body's own production decreases with age. From the age of 30, testosterone levels decline slightly on average each year.
Typical testosterone level ranges:
-
Normal: approx. 300–1000 ng/dl (nanograms per deciliter)
-
Low: below 300 ng/dl → indication of testosterone deficiency
-
High: over 1000 ng/dl → possibly overproduction or steroid use
👉 You can reliably find out whether your level is within the normal range with a hormone test for men.
Measure testosterone levels – how it works
You can determine your testosterone level in various ways:
-
Blood test at the doctor’s office – the standard method, usually performed while fasting in the morning.
-
At-home test – a simple finger-prick blood sample analyzed in a laboratory.
-
Saliva test – less common, but provides additional information.
👉 A convenient option is a hormone test from the hormone tests category that you can order online.
Testosterone deficiency – causes & symptoms
Testosterone deficiency (hypogonadism) occurs when the body produces too little of the hormone. Causes may include age, obesity, stress, illnesses, or an unhealthy lifestyle.

Typical symptoms of testosterone deficiency:
-
Fatigue and lack of motivation
-
Declining muscle strength & reduced muscle mass
-
Increased body fat (especially abdominal fat)
-
Loss of libido and erectile problems
-
Sleep disorders
-
Mood swings and depressive moods
-
Concentration problems
👉 If you recognize these symptoms in yourself, you should take a testosterone deficiency test to get clarity.
Testosterone deficiency in men – distinctive signs
In men, testosterone deficiency often manifests as:
-
Reduced beard growth and body hair
-
Reduced bone density (risk of osteoporosis)
-
Lower sperm production
Testosterone deficiency test – how to get certainty
A testosterone deficiency test can help you check whether your levels are within the normal range. A small blood test is all that is needed. Especially convenient: hormone tests for men that you can perform at home.
Boost testosterone – natural & medical approaches
If your level is too low, there are various approaches:
Natural methods
-
Strength training & exercise: particularly important for testosterone production
-
Diet: plenty of protein, healthy fats, zinc, and vitamin D
-
Stress management: Cortisol (the stress hormone) lowers testosterone
-
Sleep: 7–9 hours per night increase hormone levels
Medical treatment
-
Hormone replacement therapy (TRT): prescribed by doctors when the deficiency is severe
-
Gels, injections, or patches can regulate levels
👉 You can find out whether treatment is necessary after a blood test for men.
