What is
low testosterone?
Testosterone is the primary male sex hormone. Produced mainly by the testicles, regulated by signals from the brain (LH and FSH from the pituitary). It governs sexual function and libido, muscle mass and strength, bone density, red blood cell production, mood, energy, and cognitive function. It declines naturally with age — about 1% per year after age 30 — but in some men, the decline starts earlier or progresses faster, producing symptoms that genuinely affect quality of life.
Clinically, low testosterone (hypogonadism) is diagnosed when total testosterone is below 300 ng/dL on two separate morning samples, plus consistent symptoms. Neither the number alone nor the symptoms alone are sufficient. A man with mildly low testosterone but no symptoms doesn't need treatment. A man with completely normal testosterone but classic symptoms needs investigation of other causes — fatigue and low libido aren't always testosterone-driven.
Two important distinctions:
- Primary hypogonadism — the testicles aren't producing enough testosterone, even though the brain is signalling normally. LH and FSH are high. Causes: testicular damage, Klinefelter's, prior chemotherapy, undescended testes.
- Secondary hypogonadism — the brain isn't sending enough signal, so the testicles don't produce. LH and FSH are low or normal. Causes: pituitary tumours, obesity-related, opioid use, steroid use, severe systemic illness.
The signs men often
attribute to ageing.
Low testosterone symptoms are notorious for being non-specific. Each one alone could have many causes. The pattern, taken together, is what makes the picture suggestive — and what makes it worth testing.
Sexual symptoms (most specific):
- Reduced libido (interest in sex)
- Fewer spontaneous erections, particularly morning erections
- Erectile difficulties
- Reduced semen volume on ejaculation
Physical symptoms:
- Persistent fatigue, low energy through the day
- Reduced muscle mass and strength despite training
- Increased body fat, particularly central / abdominal
- Hot flushes (uncommon but possible)
- Reduced beard and body hair growth
- Breast tenderness or enlargement (gynaecomastia)
Cognitive and mood symptoms:
- Low mood, irritability, depression
- Reduced motivation
- Brain fog, difficulty concentrating
- Reduced sense of wellbeing
- Sleep disturbance
Other:
- Reduced bone density (long-term)
- Anaemia in severe cases
- Reduced exercise tolerance
Men often present with two or three of these and assume they're stress-related or age-related. Maybe — but it's worth testing. The blood draw is one morning sample; the result is back in 48 hours.
Why testosterone
drops.
Some causes of low testosterone are reversible. Some aren't. Knowing which matters for treatment.
Reversible / modifiable causes:
- Obesity — adipose tissue converts testosterone to oestrogen, lowering serum levels. Weight loss can normalise testosterone in many men.
- Type 2 diabetes / metabolic syndrome — strongly associated with low T. Glucose control and weight loss can help.
- Sleep apnoea — testosterone is largely produced during sleep. Untreated sleep apnoea suppresses it significantly. CPAP treatment can restore normal levels.
- Chronic opioid use — strongly suppresses testosterone. Reduction or alternative pain management often restores it.
- Anabolic steroid use — past or current. Suppresses the body's own testosterone production for months to years after stopping.
- Chronic alcohol — heavy drinking suppresses testosterone production.
- Some medications — certain antidepressants, anticonvulsants, glucocorticoids, GnRH agonists for prostate cancer.
- Chronic stress — sustained cortisol elevation suppresses testosterone.
Less reversible causes:
- Klinefelter's syndrome (XXY) — genetic. Lifelong testosterone replacement usually needed.
- Prior testicular damage — orchitis, trauma, surgery, chemotherapy, radiation.
- Undescended testes — particularly if not corrected in childhood.
- Pituitary tumours or surgery — affect the signalling from the brain.
- Haemochromatosis — iron overload affecting multiple endocrine glands.
- Ageing (andropause) — natural age-related decline. Treatable but not "fixable."
The right tests,
done at the right time.
Low testosterone diagnosis requires two confirmed values on properly-timed blood samples. A single value is not enough — testosterone fluctuates significantly with time of day, recent illness, sleep, and other factors.
Standard workup at Kalra Endo-Uro Care:
- Two morning testosterone samples — drawn between 8–10 AM, fasting, on two separate days at least a week apart. This is the diagnostic standard. Afternoon samples are not reliable.
- Free testosterone — calculated or measured. Particularly useful when total testosterone is borderline.
- SHBG (sex hormone binding globulin) — affects how much testosterone is biologically active.
- LH and FSH — distinguishes primary from secondary hypogonadism (testicular vs pituitary cause).
- Prolactin — high prolactin from pituitary tumours suppresses testosterone.
- Oestradiol — useful in obese patients where conversion to oestrogen is increased.
- Thyroid function — thyroid disease mimics low T symptoms.
- HbA1c — diabetes screen.
- Full blood count — baseline before any TRT; haematocrit rises with treatment.
- PSA — baseline before any TRT in men over 40; testosterone can stimulate existing prostate cancer.
- Lipid profile — cardiovascular baseline.
- Pituitary MRI — only in selected cases (very low LH/FSH, very low testosterone, high prolactin, visual symptoms).
- Semen analysis — for men who want children, before any treatment decision.
From lifestyle change
to testosterone replacement.
Treatment of low testosterone is a graded approach. Lifestyle and underlying cause first. Medical alternatives second. Testosterone replacement therapy (TRT) only when other options aren't appropriate or haven't worked.
Step 1 — Lifestyle interventions (always first):
- Weight loss if overweight — most powerful single intervention in many men
- Strength training 3–4 times weekly
- Sleep optimisation — 7–8 hours, treating sleep apnoea if present
- Stop or reduce alcohol
- Stop anabolic steroids (under supervision — abrupt cessation has issues)
- Stress management — sometimes including counselling
- Reduce opioid use where possible
Step 2 — Medical alternatives to TRT:
- Clomiphene citrate — stimulates the body's own testosterone production. Particularly useful in younger men who want to preserve fertility. Effective in secondary hypogonadism.
- hCG (human chorionic gonadotropin) — directly stimulates the testicles. Used alone or in combination.
- Anastrozole — for men with high oestrogen levels (often obese). Reduces conversion of testosterone to oestrogen.
- Treatment of underlying cause — addressing prolactinoma, sleep apnoea, opioid dependence, etc.
Step 3 — Testosterone Replacement Therapy (TRT):
- Injectable testosterone — most common form globally. Weekly or every-two-week injections. Provides stable levels with proper dosing.
- Testosterone gels — daily application to skin. Stable levels but requires care to avoid transfer to family members.
- Long-acting injections (testosterone undecanoate) — every 10–14 weeks. Convenient but less flexible if issues arise.
- Pellets or implants — less commonly used in India.
What testosterone replacement
actually involves.
Testosterone replacement therapy is widely marketed and widely misunderstood. Here's the honest picture.
What TRT does well:
- Restores libido and sexual function in most men with genuine low T
- Improves energy and reduces fatigue
- Improves mood and sense of wellbeing
- Increases muscle mass and reduces body fat (when combined with exercise)
- Improves bone density
- Improves anaemia of hypogonadism
What TRT does not do:
- Reverse normal ageing in men with normal testosterone
- Magically build muscle without exercise
- Treat depression caused by other factors
- Improve sexual performance when the cause is psychological or relational
Risks and side effects we monitor:
- Suppression of natural sperm production — TRT can cause azoospermia. For men who want children, this is the single biggest issue. Alternatives (clomiphene, hCG) preserve fertility.
- Erythrocytosis — TRT raises haematocrit; if too high, increases stroke risk. Monitored with blood counts.
- Acne, oily skin, increased body hair
- Worsening sleep apnoea in susceptible men
- Possible cardiovascular effects — evidence mixed but worth monitoring
- Possible stimulation of existing prostate cancer — not a cause of new prostate cancer, but pre-existing cancers can be stimulated. PSA monitoring matters.
- Testicular shrinkage — common, often noticeable
- Gynaecomastia — from conversion to oestrogen, particularly in obese men
Long-term commitment: TRT is generally lifelong. Once started, the body's own production further suppresses. Stopping after years often leaves a man with worse symptoms than before he started.
Safe TRT requires
structured follow-up.
Once on TRT, monitoring is essential — not optional, not "come back if you have problems." Standard follow-up:
- 3 months after starting — testosterone level (mid-cycle for injections), haematocrit, PSA, symptom review
- 6 months — same parameters, dose adjustment if needed
- Annually thereafter — full panel, examination, PSA in men over 40, lipid profile, glucose
- Symptom-driven additional reviews as needed
Patients who skip monitoring eventually develop preventable problems — erythrocytosis requiring blood donation, missed prostate issues, dose inadequacies. We build the monitoring into the prescription. No monitoring, no prescription.
Diagnosed properly.
Treated responsibly.
Not over-prescribed.
Two-sample confirmation
We don't diagnose low T on a single afternoon sample. Proper morning testing, twice, with LH/FSH and full workup. The diagnosis is the foundation of everything else.
Lifestyle and cause first
Before any TRT, we work through reversible causes — weight, sleep, alcohol, steroids, opioids. Many men resolve their symptoms here.
Fertility-preserving options
For men who still want children, we use clomiphene or hCG — alternatives that raise testosterone without suppressing sperm. Not the default everywhere.
Structured TRT monitoring
If you do need TRT, monitoring is built in. Haematocrit, PSA, symptom review on schedule. Long-term safety matters as much as the initial prescription.

Most andrology OPD is self-pay.
Indian health insurance generally does not cover testosterone replacement therapy or routine andrology OPD visits. Workup investigations may be partially covered when medically indicated. Many patients prefer to pay privately for andrology consultations to maintain confidentiality from workplace or family insurance — we accommodate this.
Low testosterone —
your questions.
If that was a morning sample, you're in the "low" range (typically defined as below 300 ng/dL). But diagnosis requires a second confirmatory sample, plus consistent symptoms. We'll repeat the test properly and assess your full picture before any treatment decision.
Likely yes — TRT suppresses the body's own testosterone production, which suppresses sperm production. Most men on TRT have severely reduced sperm counts or azoospermia. If you want future children, we use alternatives (clomiphene, hCG) that raise testosterone without suppressing sperm. Discuss before starting.
You can, but you shouldn't. Online "men's health" services often skip proper diagnostic workup, don't monitor for haematocrit or PSA, and don't address underlying causes. TRT done badly causes preventable problems. Done well, it's safe — but "well" requires structured medical care.
Libido improvement is often noticeable within 3–6 weeks. Energy and mood improvements typically follow over 2–3 months. Body composition changes take 6–12 months and require accompanying strength training. Don't judge results before 3 months.
Possibly, but often slowly and incompletely. The body's own production is suppressed during TRT, and recovery takes 6–24 months — sometimes never fully returning. Many men feel worse after stopping than before they started. TRT is generally a lifelong commitment.
The evidence is mixed but increasingly reassuring for properly-prescribed TRT in genuinely hypogonadal men. The main cardiovascular concern is erythrocytosis (raised haematocrit), which we monitor and manage with dose adjustment or blood donation when needed. Cardiovascular baseline assessment matters.
Current evidence does not support TRT causing prostate cancer. It can stimulate existing prostate cancer, which is why PSA monitoring matters before and during therapy. Men with active prostate cancer should not receive TRT.
Yes — but it's a gradual process, not a discrete event like menopause. Testosterone declines about 1% per year after 30. Most men maintain testosterone in the normal range into older age. A subset develop clinically significant low T that may benefit from intervention.
Indian health insurance generally does not cover TRT or routine andrology OPD. Diagnostic blood work may be partially covered when medically indicated. Many patients prefer paying privately for confidentiality reasons. We're transparent about costs upfront.
