Low testosterone affects energy, mood, strength, libido, and mental clarity. Eros MD evaluates your levels through comprehensive lab work, and builds a real plan based on your actual numbers, not assumptions.
about low testosterone
Testosterone is the primary male sex hormone, but its role extends far beyond sexual function. Testosterone regulates energy metabolism, muscle protein synthesis, bone density, mood, cognitive function, red blood cell production, and body fat distribution. When testosterone levels fall below optimal ranges, the effects are felt across virtually every system in the body.
Testosterone levels in men peak in the late teens and early twenties and decline at approximately 1 percent per year after age 30. The medical term for clinically low testosterone is hypogonadism, defined by both laboratory evidence of low hormone levels and the presence of symptoms. Low testosterone is estimated to affect 2 to 6 percent of adult men under 40, rising significantly with age. Roughly 20 percent of men over 60 and 30 percent of men over 70 have clinically low levels.
Despite its prevalence, low testosterone is significantly underdiagnosed. Many men and their physicians attribute its symptoms to stress, aging, or lifestyle, failing to recognize an underlying hormonal cause that is both identifiable and treatable.
symptoms checklist
Symptoms cluster across physical, sexual, and psychological categories. Recognizing the pattern matters more than any single symptom in isolation. These can also be caused by thyroid dysfunction, sleep disorders, depression, and metabolic disease, which is why Eros MD requires lab work and physician evaluation before recommending any treatment.
Persistent fatigue and low energy despite adequate sleep Decreased muscle mass and strength, even with regular exercise Increased body fat, particularly abdominal fat Reduced bone density (increases fracture risk over time) Hot flushes or night sweats (less common, more associated with severe hypogonadism) Anemia (reduced red blood cell production)
Reduced libido and sex drive Erectile dysfunction or reduced erection quality Reduced ejaculatory volume or intensity Infertility (in some cases of severe hypogonadism)
Low mood, irritability, or mild depression Reduced motivation and drive Difficulty concentrating or mental fog Reduced sense of wellbeing or purpose Poor sleep quality or insomnia
the evaluation
Diagnosing low testosterone requires blood work, not a symptom questionnaire. Evaluation begins with a comprehensive lab panel that gives your physician the full hormonal picture. Your provider interprets results in the context of your symptoms, age, health history, and goals. A number that falls within the standard reference range may still represent below-optimal function for you individually.
The standard measure. Normal range typically 300 to 1,000 ng/dL, though optimal ranges are more nuanced and depend on age and individual context.
Free T is the biologically active fraction, often more clinically relevant than total T, particularly in older men. SHBG (sex hormone-binding globulin) affects how much testosterone is free and active.
Determines whether low T is primary or secondary hypogonadism, important for treatment planning.
Complete blood count establishes baseline hematocrit for monitoring TRT effects. PSA is required before initiating TRT. Metabolic panel screens for related conditions.
treatment options
Treatment depends entirely on your lab results, symptom profile, and health history. Eros MD does not prescribe TRT reflexively. The goal is appropriate treatment for confirmed need, not maximizing prescriptions.
If your labs are normal, your provider will explore other causes for your symptoms rather than prescribing testosterone unnecessarily.
Indicated when labs confirm low testosterone and you are symptomatic. Available as topical gel or cream (daily application), subcutaneous or intramuscular injection (weekly or biweekly), or transdermal patch (daily). Form is selected based on your preference and clinical factors. Ongoing monitoring of testosterone levels, hematocrit, PSA, and symptom response is built into the plan.
For men with borderline or low-normal testosterone who are symptomatic but not yet meeting clinical TRT criteria, or men who prefer non-replacement approaches first. Lifestyle-based testosterone optimization includes sleep, resistance training, body composition, and alcohol reduction. Evidence-based supplementation where clinically appropriate.
Clomiphene citrate stimulates the body's own testosterone production without suppressing it, useful for secondary hypogonadism and men concerned about fertility. HCG can be added to TRT to maintain testicular function. Physician-determined based on labs and goals.
Low testosterone and ED commonly overlap. Restoring testosterone often improves erectile function, though some men benefit from concurrent PDE5 inhibitor therapy. Coordinated under one physician.
How it works
Labs, physician review, and a protocol built around what your biology actually shows.
Complete your confidential health assessment, covering symptoms, energy history, sexual health, medications, and relevant health conditions. Approximately 10 minutes.
Your Eros MD provider reviews your intake and orders the appropriate lab panel: total testosterone, free testosterone, SHBG, LH and FSH, CBC, PSA, and any additional markers relevant to your profile.
Lab work is completed at a convenient location near you, or via home collection where available. Results are reviewed directly by your provider.
Your provider interprets your results in the context of your symptoms and health history, and discusses findings and options with you directly.
If treatment is appropriate, your prescription is sent to a licensed pharmacy for discreet delivery. Ongoing monitoring and provider support are built into the plan.
Questions worth asking
Common symptoms of low testosterone include persistent fatigue, reduced libido, erectile dysfunction, loss of muscle mass, increased body fat, low mood, difficulty concentrating, and poor sleep. These symptoms overlap with other conditions, which is why lab testing is required for diagnosis. A symptom list alone is not sufficient.
Standard reference ranges typically define normal total testosterone as 300 to 1,000 ng/dL, but optimal levels vary by age and individual. Free testosterone and SHBG are equally important in clinical evaluation. Your Eros MD provider interprets your results in the full context of your symptoms and health picture, not just against a reference range.
Yes. Eros MD provides online evaluation and, where clinically appropriate, prescription of testosterone therapy. Testosterone is a controlled substance that requires a confirmed diagnosis, lab work, and licensed physician oversight. Eros MD does not prescribe TRT without objective lab evidence of deficiency.
TRT suppresses the body's own testosterone and sperm production, which can significantly reduce fertility while on treatment. Men who are considering having children in the future should discuss this with their provider before starting TRT. Alternatives such as clomiphene citrate can support testosterone levels without suppressing sperm production.
Many men report improvements in energy and mood within 3 to 6 weeks of starting TRT. Sexual symptoms, particularly libido and erection quality, typically improve within 3 to 6 months. Body composition changes (muscle gain, fat loss) generally require 6 to 12 months of treatment combined with appropriate exercise.
Primary hypogonadism means the testes themselves are not producing adequate testosterone (elevated LH/FSH, low testosterone). Secondary hypogonadism means the pituitary signaling to the testes is insufficient (low or normal LH/FSH with low testosterone). The distinction matters for treatment planning and is why LH and FSH are included in the Eros MD lab panel.
