Androgen Deficiency and the Role of Androgen
Calculators

 

What are Androgens?

Androgens are a group of steroid hormones that play a critical role in the development and maintenance of male characteristics. However, they are also present in females at lower levels. The primary androgen, testosterone, is produced mainly in the testes and, in lower amounts, in the adrenal glands. This essential hormone regulates critical aspects of male physiology, such as muscle growth, voice deepening, facial hair development, and reproductive function [1]. In addition to testosterone, other androgens like dihydrotestosterone (DHT) and androstenedione contribute to male reproductive tissue’s maturation and bone and muscle health maintenance. Androgens exert their effects by attaching to androgen receptors in various tissues throughout the body. They influence processes essential for physical development, libido, mood, and overall metabolic health. Although commonly associated with male health, androgens are vital for both sexes and influence a broad range of physiological functions, impacting everything from bone density to cardiovascular health.  
 

Normal Androgen levels

Normal androgen levels, particularly
testosterone, vary significantly depending on age, health, and even the
time of day. In adult men, typical testosterone concentrations range
between 300 and 1,000 ng/dL, with levels peaking during early adulthood.
However, this gradually declines by about 1 to 2% annually after age 30
[2, 3].
Various factors influence this decline, including lifestyle, chronic
diseases, and body composition. Morning is generally considered the best
time for measuring testosterone because of its diurnal pattern, with
peak levels typically occurring at that time. Levels below 300 ng/dL are
often considered clinically low. Still, a complete evaluation also
considers individual symptoms and baseline variations, as some men may
experience symptoms of androgen deficiency even within the lower end of
the normal range [4].
 

Why Androgens are essential for health

Androgens, particularly testosterone, play
vital roles beyond sexual and reproductive health; they are essential
for maintaining muscle mass, bone density, fat distribution, and
metabolic function. In men, adequate testosterone levels support muscle
growth and strength, contributing to overall physical fitness and
reducing the risk of sarcopenia, a condition marked by muscle loss that
becomes more common with age [5].
Androgens also promote bone mineral density, helping prevent
osteoporosis and related fractures as men age. The bone-strengthening
effect of androgens is critical in reducing the likelihood of
age-related falls and fractures, which can impact older adults’ quality
of life and independence. Additionally, androgens aid in red blood cell
production, which helps to prevent anaemia, a condition often associated
with low testosterone [6].
  Beyond physical health, androgens are
crucial to a person’s psychological well-being and cognitive function.
Many studies have found that low testosterone levels are linked to a
raised risk of mood disorders such as depression, anxiety, etc
[7]. Cognitive decline has also been associated
with androgen deficiency, with studies suggesting that lower
testosterone levels may contribute to memory issues and decreased
executive function in aging men [8].
Androgens are also involved in cardiovascular health, with lower levels
potentially contributing to higher risks of metabolic syndrome, insulin
resistance, and cardiovascular disease. Thus, maintaining healthy
androgen levels is essential for physical resilience and mental and
metabolic health. The many benefits of these hormones underscores their
broad impact on one’s overall well-being.  

Why Androgens Deplete

Androgen depletion, particularly the
gradual decline in testosterone levels, is a natural part of aging for
men, a process sometimes referred to as “andropause” or “late-onset
hypogonadism.” Typically, testosterone levels decrease by about 1-2%
annually after age 30 due to reduced testicular function and changes in
hormone regulation by the hypothalamus and pituitary gland
[9].
This decline is influenced not only by age but also by a range of
lifestyle factors. For instance, obesity plays a significant role in
androgen depletion because fat tissue converts testosterone into
estrogen through aromatase. This enzyme is particularly active in
adipose tissue. Furthermore, chronic illnesses like diabetes and
metabolic syndrome have been linked with lower testosterone levels. It
suggests that underlying health problems may accelerate the age-related
decline in androgens [10].
  Various medications and lifestyle
factors can also exacerbate androgen depletion. Certain drugs, including
glucocorticoids and opioids, can suppress the
hypothalamic-pituitary-gonadal (HPG) axis, reducing testosterone
production [11].
Psychological stress and sleep disturbances can lead to increased
cortisol levels, which may disrupt testosterone synthesis and further
depress androgen levels. Furthermore, conditions that affect liver,
kidney, or lung function can impact hormone metabolism and disrupt the
balance of androgens in the body. Consequently, androgen depletion is
not solely an outcome of aging but also reflects the cumulative impact
of lifestyle, chronic health issues, and environmental factors on the
hormonal balance in men.  

How to treat Androgen depletion

Treating androgen depletion typically
involves testosterone replacement therapy (TRT), which is administered
through injections, transdermal patches, gels, or subcutaneous implants
to restore testosterone levels to a normal range [12].
TRT has shown effectiveness in alleviating symptoms such as reduced
libido, fatigue, low muscle mass, and depressive symptoms in men
diagnosed with low testosterone, also known as hypogonadism. Studies
indicate that TRT can improve bone density, muscle strength, and mood,
contributing to better quality of life and functional health in men
suffering from testosterone deficiency. However, TRT is not without
risks; potential side effects include erythrocytosis (an increase in red
blood cells), possible aggravation of sleep apnea, and concerns
regarding cardiovascular health, which necessitate regular monitoring
and careful patient selection for therapy [13].
  In addition to TRT, lifestyle
modifications are critical in managing androgen depletion. Exercise,
particularly high-intensity interval training (HIIT) and resistance
training, has been shown to boost natural testosterone production and
improve metabolic health [14].
Dietary adjustments (such as reducing sugar intake and managing weight)
have been shown to support healthy testosterone levels. Also, sufficient
intake of vitamins (especially vitamin D) and minerals like zinc can
boost blood testosterone levels. Stress management techniques, including
adequate sleep and mindfulness, can also help mitigate testosterone
depletion. For some individuals, these lifestyle approaches may delay or
even reduce the need for TRT. Typically, experts adopt a holistic
treatment strategy for androgen deficiency.  

The Benefits of an Androgen Calculator

An androgen calculator is a clinical tool
for evaluating the likelihood of androgen deficiency, particularly in
aging men. It provides a standardized and effective method for assessing
testosterone levels and associated symptoms. These calculators combine
objective measures, such as serum testosterone concentrations, with
subjective symptom assessments to generate a score that helps healthcare
providers identify individuals at risk for hypogonadism. This approach
supports early detection and facilitates a more personalized evaluation
of testosterone deficiency, considering variable factors like age, body
mass index (BMI), and comorbidities, which can influence androgen levels
and symptom severity [15].
By integrating multiple variables, androgen calculators allow clinicians
to make more informed decisions about whether further diagnostic testing
or intervention is needed, ultimately improving patient outcomes.
  Furthermore, using an androgen
calculator brings significant benefits in terms of patient management.
They aid in monitoring the effectiveness of testosterone replacement
therapy (TRT) or lifestyle interventions by providing a quantifiable
method for tracking changes in androgen levels over time. It enables
doctors to identify trends and adjust treatment plans, ensuring patients
receive the most appropriate care. Moreover, the accessibility and ease
of use of androgen calculators reduce the reliance on subjective symptom
reports, which can be influenced by factors such as mood or general
health perceptions. As a result, they promote more objective,
evidence-based treatment decisions and reduce the chances of
misdiagnosis, leading to more efficient management of androgen
deficiency in clinical practice [16].
 

The Benefits of an Androgen Calculator

The ADAM Calculator

The
Androgen Deficiency in the Aging Male
(ADAM) calculator by
GlobalRPH is designed to assess the likelihood of androgen deficiency,
particularly in older men. This tool integrates subjective and objective
measures and comprehensively evaluates testosterone deficiency. It takes
into account factors such as age, total testosterone levels, and
clinical symptoms commonly associated with hypogonadism, including low
libido, fatigue, and reduced muscle mass. The calculator assigns a
numerical score based on these variables, which helps clinicians
evaluate whether further diagnostic testing, such as free testosterone
levels or luteinizing hormone testing, is required.  
One of the key advantages of this calculator is its ability to
facilitate early diagnosis of androgen deficiency, a condition often
underdiagnosed due to the overlap of its symptoms with other age-related
health issues. Incorporating various parameters- such as a patient’s BMI
and overall health status- into the assessment allows for a more
tailored approach to treatment, ensuring that individuals with androgen
deficiency receive appropriate interventions. The calculator can also
guide clinicians in determining the potential benefits of testosterone
replacement therapy (TRT) or lifestyle modifications. In this way, it
provides a structured method for monitoring the progression of androgen
deficiency over time and adjusting treatment plans accordingly,
ultimately improving patient care. This tool is handy in populations
where testosterone decline is typical. Still, it may be overlooked,
aiding healthcare providers in making more informed, evidence-based
decisions about treatment options [17].
 

Some limitations of Androgen Deficiency
Calculators

• Over-reliance on Self-Reported Symptoms

• Androgen
  deficiency calculators often rely on subjective symptom reports from
  patients, such as fatigue or mood changes, which can be influenced by
  other conditions (e.g., depression, sleep apnea) or general aging. It
  may lead to misinterpretation or overdiagnosis of testosterone
  deficiency.

• Standardized Parameters

• Many
  calculators use standardized parameters (age, testosterone levels, BMI)
  that may not fully account for individual variations in health status or
  the influence of comorbidities. It can limit the accuracy of the
  assessment for some patients, particularly those with complex medical
  histories.

• Limited to Total Testosterone Levels

• These
  calculators primarily focus on total testosterone levels, which may not
  reflect the bioavailable testosterone in the body. Free testosterone and
  other markers like luteinizing hormone or sex hormone-binding globulin
  (SHBG) are sometimes more accurate indicators of androgen deficiency.
  Still, they may not be considered in these calculators.

 

Conclusion

Androgens, particularly testosterone, are
vital steroid hormones that play an essential role in male development.
However, the level of this crucial hormone can sometimes decrease
because of aging or other health problems with significant health
consequences. An androgen deficiency calculator like the ADAM calculator
provides clinicians with an effective and reliable way to identify and
assess men at risk of androgen deficiency. It also enables doctors to
provide personalized patient treatment and monitor outcomes.
