Saliva hormone testing is a method for measuring hormones that is generally considered reliable and useful, especially in certain contexts. Here are some key points regarding the reliability of saliva hormone testing:
Benefits of saliva hormone tests
Non-invasive: Compared to blood tests, saliva samples are easier and less invasive to collect.
Stress-free: Since sampling is stress-free, the results are less affected by stress hormones.
Repeatable measurements: It is easier to collect multiple samples throughout the day, which is helpful in investigating hormone fluctuations.
Specifically for certain hormones: They are particularly useful for measuring free, biologically active hormones, such as cortisol, DHEA, and some sex hormones (e.g. progesterone, estradiol).
Applications
Saliva hormone tests are particularly useful in certain clinical and research settings, such as:
Monitoring cortisol levels to assess adrenal function and stress levels.
Measurement of hormones related to the female cycle and menopause.
Long-term monitoring of hormones without the need for frequent blood draws.
Saliva hormone tests are a valuable and reliable method for measuring certain hormones, especially when performed and interpreted correctly.

Testosterone is the primary male sex hormone—it influences libido, muscle strength, energy, mood, and much more. However, estrogen and progesterone also have important functions in men and should not be underestimated:

Testosterone is responsible for the development of male characteristics during puberty, maintains muscle mass, stimulates libido, and supports motivation and concentration. A deficiency can lead to a lack of drive, erectile dysfunction, and muscle loss.

Estradiol (a form of estrogen) is produced in men through the conversion of testosterone. It is important for bone health, cognitive function, and a stable cardiovascular system. However, elevated estrogen levels in men can lead to fat gain, mood swings, or breast development.

Progesterone, often perceived as "female," also plays a role in men: it helps maintain hormonal balance, has a balancing effect on the nervous system, and supports the production of other hormones. A deficiency can affect sleep quality and stress resilience, among other things.

Elevated estrogen levels in men can disrupt the sensitive balance between male and female hormones – often with significant physical and psychological consequences.

Typical signs of estrogen dominance in men include:
• Weight gain (especially in the abdominal and chest areas)
• Gynecomastia (enlargement of breast tissue)
• Loss of libido and erectile dysfunction
• Mood swings, irritability, or depressive moods
• Decreased performance, especially in strength and endurance

Often, excessively high estrogen levels result from an increased conversion of testosterone to estradiol (aromatase activity), for example, in cases of obesity or chronic stress. Alcohol, certain medications, or environmental hormones (e.g., plasticizers) can also play a role.

A hormone test helps to identify this imbalance – and, in collaboration with an expert, to counteract it specifically, for example, through diet, exercise, micronutrients, or therapeutic measures.

DHEA (dehydroepiandrosterone) is a steroid hormone produced by the adrenal glands. It's a precursor hormone, meaning it can be converted into other hormones in the body, particularly sex hormones like estrogen and testosterone. Here's some important information about DHEA:
Functions of DHEA
Precursor for sex hormones: DHEA is converted into the sex hormones estrogen and testosterone, which perform many important functions in the body.
Immune system support: DHEA can strengthen the immune system and help reduce inflammation.
Influence on mood and well-being: DHEA can improve mood, increase energy, and promote overall well-being.
Bone and muscle health: DHEA contributes to the maintenance of bone density and muscle mass.
Anti-aging effects: It is often associated with anti-aging effects because DHEA levels in the body decrease with age.
Production and regulation
Adrenal glands: DHEA is mainly produced in the zona reticularis of the adrenal cortex.
Age: DHEA production peaks in early adulthood and gradually declines with age. DHEA levels are often significantly lower in older adults than in younger people.
Stress: Chronic stress can affect DHEA production because the adrenal glands also produce cortisol, a stress hormone.

Testosterone deficiency, also known as hypogonadism, can cause various physical and psychological symptoms. If you suspect you may have a testosterone deficiency, there are several steps you can take to find out:
1. Recognize symptoms
Look out for typical symptoms of testosterone deficiency. These may include:
Physical symptoms:
Low libido (sexual desire)
Erection problems
Reduced muscle mass and strength
Increase in body fat
Loss of body hair
Fatigue and low energy levels
Osteoporosis (reduced bone density)
Psychological symptoms:
Depressive mood
irritability
Difficulty concentrating
Memory problems
Testosterone deficiency can have a significant impact on quality of life, but it is treatable. Through a thorough examination and appropriate testing, testosterone deficiency can be diagnosed and effectively treated.
