Testosterone deficiency: How does a low level show itself?
Testosterone deficiency usually develops gradually over months or years. The symptoms are often attributed to stress, age or general exhaustion – which makes it difficult to recognize.
Testosterone is the most important androgen – a group of hormones that are largely responsible for growth, body composition and reproduction. In men, it is mainly produced in the testes, and in women in the ovaries as well as the adrenal cortex.
In men, testosterone levels usually peak between the ages of 20 and 30. After that, they naturally decline by about one percent per year – a process that often becomes noticeable from around the age of 40. In women, the decline is particularly pronounced after menopause.
Symptoms of testosterone deficiency in men
Because testosterone is involved in so many processes in the body, deficiency symptoms can appear in very different areas – from energy and muscles to mental wellbeing and sexuality:
- Lack of drive and exhaustion despite sufficient sleep
- Muscle loss – despite regular training, muscle growth does not occur
- Increase in abdominal fat
- Loss of libido and erectile dysfunction
- Poorer recovery after physical exertion
- Mood changes such as irritability or depressive moods
- Concentration problems
- Reduced bone density over the long term
The 3 biggest testosterone killers in everyday life
In addition to genetic predisposition and the natural aging process, lifestyle factors play a decisive role in how strongly testosterone levels decline – and how early. Three of them are particularly well documented.
1. Cortisol – the biochemical antagonist
Cortisol and testosterone are both formed from cholesterol – via different metabolic pathways, but with a shared bottleneck: When the body is under chronic stress and cortisol production is running at full speed, a large proportion of the available precursors is directed toward cortisol. This principle is referred to as “pregnenolone steal”.
In addition, cortisol inhibits the release of LH (luteinizing hormone) – the hormone from the pituitary gland that first triggers testosterone production. Chronic stress therefore acts on two levels at the same time: It consumes biochemical resources and slows down the hormonal control system.
For everyday life, this means: Chronic stress directly interferes with hormone balance. Stress-reduction measures – sleep, relaxation techniques and exercise – are therefore not wellness recommendations, but biochemically justified hormone optimization. Our guide “Lowering cortisol” explains how cortisol levels can be specifically regulated.
2. Lack of sleep – the underestimated hormone disruptor
Most testosterone release does not take place during the day, but at night during deep sleep phases. Researchers showed that just one week with only five hours of sleep per night can lower testosterone levels in young, healthy men by up to 15 percent.
The mechanism behind this is hormonal: LH release is highest during deep sleep – the signal that prompts the Leydig cells in the testes to produce testosterone. Anyone who sleeps too little or restlessly interrupts this signaling pathway.
For optimal testosterone production, seven to nine hours of sleep are physiologically necessary.
3. Abdominal fat – hormonally active tissue
Visceral fat – the fatty tissue around the internal organs – is not a passive energy store. It is metabolically active and contains high amounts of the enzyme aromatase. This enzyme converts testosterone into estrogen.
The result is a self-reinforcing cycle: More abdominal fat means more aromatase activity. This increases estrogen formation and simultaneously lowers testosterone levels. People with pronounced abdominal fat statistically more often have low testosterone values, and low testosterone levels in turn make fat loss more difficult.
Anyone who reduces abdominal fat – through nutrition and training – therefore directly influences hormone balance.
Not just a men’s issue: Why women also need testosterone
In public perception, testosterone is almost exclusively associated with men. Yet it is also an essential hormone for women – although in significantly lower concentrations.
In women, it contributes to:
- Libido and sexual wellbeing
- Bone health – important for the prevention of osteoporosis
- Energy and mental resilience
- Muscle tone and body composition
A testosterone deficiency in women often manifests as persistent fatigue, declining sexual interest and a general loss of drive – symptoms that occur particularly frequently during menopause. The use of hormonal contraceptives such as the pill can also lower testosterone levels, as certain preparations increase the production of sex hormone-binding globulin (SHBG) – a transport protein that binds testosterone and thereby makes it inactive.
At the same time, the following applies: Too much testosterone in women is also problematic. Elevated levels – as in polycystic ovary syndrome (PCOS) – can cause cycle irregularities, acne, unwanted hair growth and fertility problems.
The goal is always individual hormonal balance – not the highest possible value.
Micronutrients: The building blocks of hormone production
Hormones do not form on their own – the body needs specific micronutrients as cofactors for their synthesis. These are substances without which enzymatic reactions in hormone production cannot take place – and this is exactly where the difference to “testosterone boosters” lies.
Myth: testosterone boosters
A healthy body cannot be pushed beyond its genetic maximum by miracle remedies. In scientifically grounded micronutrient medicine, the aim is not to artificially stimulate hormones – but to compensate for deficiencies that slow down the body’s own hormone production.
If the supply of central micronutrients is insufficient, hormone synthesis stalls. In such cases, a high-quality micronutrient preparation can bring the body’s own production back into the physiological normal range. However, those who have no deficiency will not achieve measurable changes in hormone levels through additional micronutrients.
Zinc – essential for testosterone synthesis
Zinc is a trace element involved in numerous enzymatic reactions – including several steps of the body’s own hormone formation. Testosterone belongs to the steroid hormones that are formed from cholesterol.
For its production, zinc is relevant at several points:
- It supports enzymes that gradually convert cholesterol into testosterone
- It inhibits the activity of aromatase – the enzyme that converts testosterone into estrogen
- It is necessary for the release of LH – the hormonal starting signal for testosterone production
In studies, researchers observed that zinc deficiency is associated with lower testosterone values and that levels can be normalized again through targeted supplementation.
Zinc is found in foods such as red meat, oysters, legumes and pumpkin seeds. However, people with high sweat loss, a vegan diet or chronic inflammatory bowel diseases have an increased risk of suboptimal supply.
Magnesium – cofactor for more free testosterone
Magnesium is involved in more than 300 enzymatic reactions and supports, among other things, normal protein synthesis – a basic prerequisite for the formation of enzymes and transport proteins that play a role in steroid hormone metabolism.
Another particularly relevant aspect could be: Magnesium influences how much testosterone is freely available in the blood. A large proportion of circulating testosterone is bound to a transport protein called SHBG (sex hormone-binding globulin) and is therefore biologically inactive. Only unbound, “free” testosterone can bind to cells and exert its effect.
Researchers showed in studies that higher magnesium levels are associated with a higher proportion of free testosterone. This connection is particularly relevant for older men, in whom SHBG levels increase and more and more testosterone is therefore bound and inactive.
FormMed tip
Magnesium also regulates the excitability of the nervous system and supports restful sleep quality – a factor that indirectly helps determine testosterone production, as most hormone synthesis takes place during deep sleep.
Our guide “Magnesium and sleep” explains how magnesium specifically supports sleep and what matters when choosing the right compound.
Vitamin D – the sun hormone
Strictly speaking, vitamin D is not a vitamin, but a precursor of the steroid hormone calcitriol – formed from cholesterol when the skin is exposed to sunlight. It acts via specific receptors found in almost all tissues – including the Leydig cells of the testes, where testosterone is produced.
These receptors suggest a direct connection: In a number of studies, researchers observed that men with low vitamin D levels more often also had lower testosterone values. Randomized controlled trials are also investigating whether vitamin D supplementation has an influence on testosterone levels.
Vitamin D deficiency is widespread in Germany: In winter, the skin produces hardly any vitamin D due to the flat angle of the sun. A regular check of vitamin D levels in the blood is therefore recommended. Our guide “Vitamin D – the right dosage” explains how much vitamin D is useful depending on the season.
Selenium and vitamin E – protection for hormone-producing cells
The Leydig cells in the testes, where testosterone is formed, are particularly sensitive to oxidative stress – they metabolize large amounts of cholesterol and produce free radicals in the process. Antioxidants such as selenium and vitamin E protect these structures.
Selenium is a component of antioxidant enzymes such as glutathione peroxidase and also contributes to normal sperm formation. Since soils in Germany are low in selenium, supply through plant-based foods is often difficult. Good sources are Brazil nuts, fish, eggs and meat.
Vitamin E is the most important fat-soluble antioxidant and primarily protects the lipid structures of cell membranes – for example in hormone-producing cells. High-quality preparations contain vitamin E as a natural complex of tocopherols and tocotrienols.
Testosterone and plant compounds: What does research show?
In addition to micronutrients, numerous plant compounds are also being scientifically investigated that have been used in traditional medicine for centuries to support vitality, stress adaptation and men’s health.
Researchers are looking at different mechanisms of action – from effects on stress regulation to possible influences on hormonally active enzymes.
Adaptogens: Ashwagandha and maca
Adaptogens are plants that have been used in traditional medicine for centuries to help the body adapt to stress. In recent years, they have also been studied more closely scientifically.
Ashwagandha (Withania somnifera)
Ashwagandha is one of the best-studied adaptogens. Research focuses primarily on its influence on cortisol levels: In two recent meta-analyses, researchers evaluated data from randomized controlled trials. Since cortisol and testosterone are closely linked in hormone balance, the possible effect of ashwagandha on testosterone levels is also of scientific interest – especially in combination with physical training.
Maca (Lepidium meyenii)
Maca is a plant from the Andes that is traditionally used to support energy and libido. Researchers are investigating how maca affects subjective sexual wellbeing. The plant compounds it contains include glucosinolates and macamides – plant compounds whose exact mechanisms are still being studied.
Fenugreek, nettle and tribulus
Unlike adaptogens, which are studied in connection with stress regulation, fenugreek, nettle and tribulus focus on hormone metabolism.
Fenugreek (Trigonella foenum-graecum)
Fenugreek contains furostanol saponins. Possible effects on aromatase and 5α-reductase are discussed, among other things – two enzymes that play a role in steroid hormone metabolism.
Nettle (Urtica dioica)
Scientists are studying certain lignans from nettle root. A possible influence on the binding of testosterone to SHBG is being researched – a mechanism that is also investigated in connection with magnesium.
Tribulus (Tribulus terrestris)
Tribulus is one of the best-known plants in men’s health. Valuable constituents are steroid saponins such as protodioscin. Research is being conducted on possible effects on hormone regulation and sexual function.
FormMed tip – high-quality extracts instead of plant powders
Simple plant powders contain the valuable constituents in highly fluctuating amounts. Standardized extracts, by contrast, guarantee a defined content and form the basis of scientific studies. For this reason, FormMed uses standardized plant extracts.
Nutrition and training: How lifestyle influences testosterone
Lifestyle factors such as nutrition and training directly affect the biochemical prerequisites for testosterone production: They provide the body with building blocks for hormone formation, influence energy metabolism and set hormonal stimuli that stimulate production.
Nutrition: What influences testosterone levels
Testosterone belongs to the steroid hormones that are formed from cholesterol. The body produces most of this itself in the liver. Nutrition nevertheless influences hormone production – through the interplay of fat intake, proteins, calories and blood sugar.
The most important nutritional levers for testosterone levels are:
- Sufficient fats of good quality: A very low-fat diet can be associated with lower testosterone values. Monounsaturated and polyunsaturated fatty acids from olive oil, avocado, nuts and fatty sea fish such as salmon are recommended.
- Regular protein intake: Proteins provide amino acids as building blocks for muscle recovery as well as for proteins that transport hormones in the blood.
- Reduced sugar consumption: High sugar consumption causes strong blood sugar fluctuations and increased insulin levels. Over time, this can lead to more testosterone being bound in the blood and therefore becoming inactive.
- Sufficient calories: Chronic calorie restriction is a known stressor that raises cortisol levels and slows testosterone production.
Strength training – the most effective natural hormonal stimulus
Short, intense strength training is the most effective natural stimulus for testosterone production. Intensive muscle work – especially with large muscle groups such as the leg and back muscles – releases growth hormones and testosterone. Researchers observed that compound exercises such as squats and deadlifts trigger particularly strong hormonal responses.
Hours of endurance training at a moderate pace, on the other hand, have hardly any positive influence on testosterone levels. Excessive cardio training can even have the opposite effect in some people: It increases cortisol levels and prolongs recovery.
Two to four strength training sessions per week with sufficient recovery in between are hormonally much more effective than daily, exhausting training.
Conclusion: Increasing testosterone – systematically instead of with miracle remedies
Testosterone can be influenced naturally – but not through individual “boosters” or miracle remedies. What matters is the interplay of a healthy sleep rhythm, moderate cortisol levels, regular strength training and a balanced diet.
The real lever for increasing low testosterone is a holistic approach: First address the causes – stress, lack of sleep, abdominal fat – then ensure the biochemical building blocks are in place. On this basis, targeted micronutrients such as zinc, magnesium and vitamin D can support the body’s own hormone production. Plant extracts from ashwagandha, maca, fenugreek or tribulus are being scientifically investigated and can be used additionally in standardized quality.
Frequently asked questions about increasing testosterone
In men, testosterone levels begin to gradually decline from the age of 30 – by about 1 percent per year. From the age of 40 to 45, this decline often becomes noticeable.
In women, the decline is particularly noticeable after menopause – usually between the ages of 45 and 55 – as production in the ovaries decreases sharply.
Low testosterone levels often manifest as lack of drive, emotional flatness, reduced libido and a poorer response to physical training.
An important note: Character traits such as aggression or dominance are often incorrectly equated directly with testosterone in public discussion. In fact, the connection is more complex – testosterone influences behavior in context, but is not its sole driver.
The combination of sufficient sleep (7–9 hours), targeted strength training, stress reduction and nutrient-rich nutrition has the greatest influence.
Individual measures such as zinc or vitamin D supplementation are only truly effective if an actual deficiency is present. A holistic strategy is clearly superior to a single-factor approach.
Testosterone itself is not contained in any food.
However, certain foods provide important building blocks and cofactors for the body’s own hormone production: zinc-rich foods such as oysters, red meat and pumpkin seeds, vitamin D from fatty sea fish such as salmon and mackerel, and healthy fats from olive oil, avocado and nuts for balanced fat intake.
No single food directly lowers testosterone levels. The discussion mainly focuses on soy products because of their phytoestrogens, as well as mint, licorice and larger amounts of alcohol. For soy, the data do not show clinically relevant effects with moderate consumption – the concern is often greater than the scientific basis.
Also unfavorable for hormone balance are sugar, trans fatty acids and highly processed foods – through their influence on abdominal fat, insulin levels and inflammatory processes.
Too much intensive training without sufficient recovery can permanently increase cortisol levels and slow testosterone production. The ratio of testosterone to cortisol is considered a marker of training and recovery status. Moderate intensity with sufficient regeneration is hormonally much more favorable than excessive training.
Maca may influence libido and subjective wellbeing more than testosterone levels themselves – through mechanisms that are not yet fully understood. As an additional plant compound for lack of drive and loss of libido, maca is scientifically interesting, but it is not a classic hormone booster.
Medical hormone therapy is only useful in cases of medically confirmed testosterone deficiency (hypogonadism). The diagnosis is made by blood test, with both total testosterone and freely available testosterone playing a role. This decision lies exclusively with the doctor and should not be made on the basis of self-diagnosis.
Lifestyle and micronutrients, on the other hand, can be useful for anyone whose values are at the lower end of the normal range – as a holistic approach to supporting the body’s own hormone production.
This question must be considered in a medically differentiated way. For a long time, the hypothesis was that testosterone promotes prostate cancer growth. Current research paints a more nuanced picture: In healthy men, a physiologically normal testosterone level is not a risk factor. Existing prostate carcinomas, however, may be hormone-dependent. In the case of a known prostate disease or family history, testosterone therapy should always be medically supervised.
In Germany, there are no officially approved testosterone preparations specifically for women. In certain clinical situations – for example in confirmed deficiency after menopause – they can nevertheless be used off-label, meaning outside the actual approval. Such therapy requires careful medical evaluation and supervision.
Dietary supplements with micronutrients such as zinc, magnesium and vitamin D or with adaptogens such as ashwagandha and maca, on the other hand, can also support the biochemical prerequisites in women without directly interfering with the hormonal system.
