Causes of Low Testosterone
Often multi-factorial — and sometimes reversible.
Low testosterone can be driven by internal biology, lifestyle, or health conditions — and in many cases it's a combination. Before considering treatment, it's important to identify what's pushing your levels down.
Factors That Lower Testosterone
Age-Related Decline
Testosterone naturally declines with age — but the rate isn't always linear and isn't inevitable at every level.
Poor Sleep / Sleep Disruption
The majority of daily testosterone is produced during sleep. Chronic disruption significantly reduces output.
Chronic Stress & Elevated Cortisol
High cortisol competes with testosterone production — chronic stress creates a persistent hormonal imbalance.
Excess Body Fat / Metabolic Strain
Adipose tissue converts testosterone to oestrogen — higher body fat accelerates this process.
Under-Recovery or Overtraining
Training load without adequate recovery creates a chronic stress signal that suppresses hormone production.
Alcohol & Lifestyle Factors
Regular alcohol consumption impairs testosterone synthesis and increases conversion to oestrogen.
Certain Medications
Opioids, some antidepressants, statins and other drugs can suppress testosterone — worth reviewing at assessment.
Underlying Testicular or Pituitary Causes
Less common but important to rule out — including primary hypogonadism or pituitary dysfunction.
Identify, Confirm, Plan
We don't just prescribe — we investigate. Understanding the cause shapes the treatment.
01
Identify Reversible Drivers
Sleep, stress, weight and medication factors are assessed first — because some causes can be addressed without TRT.
02
Confirm with Blood Screening
A comprehensive panel establishes your baseline and confirms the clinical picture alongside your symptoms.
03
Build a Personalised Plan
If TRT is appropriate, we design a protocol around your physiology, goals, and lifestyle — not a template.
