Low testosterone - clinically termed hypogonadism - is one of the most common and most underdiagnosed hormonal conditions affecting Indian men. Estimates suggest that 20 to 40 percent of men over 45 have testosterone levels below the clinically optimal range, yet the vast majority are never tested or treated.
Understanding the symptoms, causes, and treatment options is the first step toward addressing a condition that quietly undermines quality of life, metabolic health, and longevity.
Symptoms of Low Testosterone
The symptoms of low testosterone are wide-ranging and often attributed to ageing, stress, or lifestyle factors when the underlying hormonal driver is missed.
Physical Symptoms
- Reduced muscle mass and strength: Testosterone is anabolic; low levels accelerate muscle loss
- Increased body fat: Particularly visceral and abdominal fat accumulation
- Fatigue and low energy: One of the most consistently reported symptoms; not relieved by rest
- Reduced bone density: Increasing fracture risk over time, particularly in older men
- Hair loss or thinning: Beyond normal age-related changes
Sexual Symptoms
- Reduced libido: Decreased interest in sexual activity, often progressive
- Erectile dysfunction: Low testosterone is a contributing factor in many cases
- Reduced semen volume
- Infertility: Testosterone is essential for sperm production
Psychological Symptoms
- Depression and low mood: Testosterone has direct effects on brain chemistry and mood regulation
- Reduced motivation and drive: Particularly in domains previously engaged
- Brain fog and difficulty concentrating
- Irritability and mood instability
Common Causes of Low Testosterone
Primary Hypogonadism
The testes are unable to produce adequate testosterone due to direct testicular impairment. Causes include:
- Klinefelter syndrome (genetic)
- Testicular injury or infection
- Chemotherapy or radiation history
- Undescended testes
Secondary Hypogonadism
The pituitary gland fails to send adequate signalling to the testes. Causes include:
- Obesity and metabolic syndrome (most common cause in middle-aged men)
- Hyperprolactinaemia (elevated prolactin)
- Pituitary tumour or damage
- Hypothalamic dysfunction
Age-Related Decline (Late-Onset Hypogonadism)
Testosterone naturally declines at approximately 1 to 2 percent per year after age 30. By 50, many men are significantly below peak levels, though not always below clinical thresholds.
Lifestyle and Environmental Factors
- Chronic stress (elevated cortisol suppresses testosterone)
- Insufficient sleep
- Excess alcohol consumption
- Endocrine-disrupting chemical exposure
- Overtraining without adequate recovery
Treatment Options
Testosterone Replacement Therapy (TRT)
Direct exogenous testosterone, available as injections, gels, or patches. Highly effective at raising levels but suppresses the body's own production and requires lifelong use once started.
Peptide Therapy for Testosterone Support
For men with secondary hypogonadism or borderline low levels, several peptides stimulate the body's natural testosterone production pathway without suppression:
- Sermorelin and Ipamorelin: Growth hormone secretagogues that indirectly support testosterone through GH-IGF-1 axis improvement
- Kisspeptin: A powerful natural activator of the hypothalamic-pituitary-gonadal axis; directly stimulates LH and FSH release, which drives testicular testosterone production
- Enclomiphene: A selective oestrogen receptor modulator that increases LH and FSH, stimulating natural testosterone production while preserving fertility
Lifestyle Optimisation
For men with borderline levels driven by lifestyle factors: resistance training, sleep optimisation, stress management, and weight loss (particularly visceral fat reduction via GLP-1) can produce meaningful testosterone improvement.
When to Test
If you have two or more of the symptoms listed above, testing is warranted regardless of age. At Longegra, testosterone testing is part of our standard intake panel, including total testosterone, free testosterone, SHBG, LH, FSH, prolactin, and oestradiol.
This comprehensive panel tells you not just whether your testosterone is low, but why, which is essential for choosing the right treatment approach.
Frequently Asked Questions (FAQs)
Most clinical guidelines define low testosterone as a total testosterone below 300 ng/dL (10.4 nmol/L), though symptoms can occur at higher levels if free testosterone is disproportionately suppressed by elevated SHBG. Context matters, and a physician should interpret results alongside symptoms.
