Restore energy, drive and balance with evidence-led care.

TRT delivers bioidentical testosterone via several routes, each with distinct advantages. Choice depends on patient preference, lifestyle, fertility plans, and medical history.

Topical gel (daily application): Applied to upper arms, shoulders or abdomen each morning. Produces stable physiological levels. Requires care to avoid transferring to partners or children through skin contact. Most flexible to stop if needed.

Intramuscular injection: Shorter-acting preparations (testosterone enanthate or cypionate) given every 2-3 weeks. Longer-acting preparations (testosterone undecanoate) given every 10-14 weeks after a loading phase. Some prefer the convenience; others dislike the cyclical highs and lows of the shorter formulations.

Effectiveness: Most patients experience meaningful symptom improvement within 8-12 weeks. Libido and mood often improve first; energy, muscle mass, and body composition changes follow over 3-6 months. It can take between 6-9 months to see improvement of erections in patients that have erectile dysfunction due to low testosterone levels.

Eligibility: TRT requires confirmed clinical hypogonadism - total testosterone below 12 nmol/L on two morning samples,² accompanied by symptoms. Contraindications include untreated prostate cancer, untreated severe sleep apnoea, severe heart failure, haematocrit above 50%, and active desire for fertility.

Side effects: Generally well-tolerated with monitoring. Possible effects include increased red blood cell count (managed by monitoring haematocrit), worsening of pre-existing sleep apnoea, acne, breast tenderness, and reduced fertility. PSA elevation is monitored to detect any prostate change early.

TRT suppresses the body's own testosterone production and reduces sperm count, often significantly. For those actively trying to conceive or wanting to preserve fertility for the future, alternative approaches stimulate the body's natural production rather than replacing it.

Clomiphene citrate (off-label): Originally a fertility medication, clomiphene blocks oestrogen feedback at the brain, prompting it to increase LH and FSH output - which in turn stimulates the testes to produce more testosterone. Effective in 60-70% of patients with secondary hypogonadism.³ Preserves fertility.

Human chorionic gonadotropin (HCG): An injectable hormone that directly stimulates the testes. Often combined with low-dose TRT or used alongside other treatments. Effective for both raising testosterone and preserving fertility.

Aromatase inhibitors (anastrozole, off-label): When oestrogen levels are high, blocking testosterone-to-oestrogen conversion can raise testosterone. Reserved for specific scenarios; not first-line.

Eligibility: Best for secondary hypogonadism where fertility preservation matters, or for younger patients where stimulating natural production is preferable to replacement. Less effective in primary hypogonadism (testicular failure).

Monitoring: Similar to TRT - testosterone levels, sperm parameters (if relevant), and clinical response are tracked over 3, 6 and 12 months.

For many patients with borderline-low testosterone - particularly with obesity, metabolic syndrome, or untreated sleep disorders - addressing the underlying cause restores testosterone to normal range without hormonal treatment. This is the first-line approach when criteria for TRT aren't met, and the foundation alongside TRT when they are.

Weight optimisation: For BMI above 27, structured weight loss can raise testosterone by 15-25% on average, sometimes more (see source 4 below). Medical weight loss is integrated into the hormonal treatment plan when relevant.

Sleep: Most testosterone is produced during deep sleep. Restoring 7-8 hours of consistent quality sleep, and screening for obstructive sleep apnoea where indicated, can produce meaningful improvement.

Resistance training: Regular strength training increases testosterone production and improves how the body responds to it. 2-3 sessions per week of compound movements is the evidence-based protocol.

Nutrition: Zinc and vitamin D deficiency suppress testosterone production. Adequate dietary fat (testosterone is synthesised from cholesterol) and minimal excessive alcohol are foundational.

Stress management: Chronic stress raises cortisol, which directly suppresses testosterone production. Where cortisol is elevated on testing, structured stress management is part of the protocol.

Foundational lifestyle work is included in your consultation. Additional input (dietitian, sleep medicine) is added if indicated.

TRT is a lifelong treatment for most patients. Structured monitoring is non-negotiable - it ensures the treatment continues to work, identifies side effects early, and detects any complications before they become significant.

3-month review: Total testosterone (mid-cycle for injections), free testosterone, full blood count (haematocrit), and clinical response. Dose adjusted if needed.

6-month review: Same blood panel plus lipid profile, fasting glucose/HbA1c, and PSA where indicated. DRE (digital rectal exam) at this point if not done earlier.

Annual thereafter: Comprehensive review including testosterone, haematocrit, PSA, lipids, glucose, liver function, and clinical assessment. Any new symptoms or concerns prompt additional investigation.

Your personal health concierge coordinates this monitoring schedule - booking the blood tests, sharing results, scheduling follow-up consultations, and ensuring nothing falls through the cracks. This continuity is what makes long-term hormonal care actually sustainable.

When to stop or adjust: TRT can be paused, dose-reduced, or stopped if needed. Common reasons include side effects, fertility desire, prostate concerns, or simply patient preference. Stopping is straightforward but should be done under clinical supervision.
