TRT which is testosterone replacement therapy explained simply: it’s a prescription medical treatment for confirmed low testosterone (hypogonadism), not a general energy or performance boost, and it comes with real benefits and real risks that deserve an honest look. We don’t prescribe TRT, this page is educational, and if it looks appropriate for you, we’ll support a referral to a doctor. Here are six essential facts.
1. TRT Is for Confirmed Hypogonadism, Not Just Low Energy
Proper diagnosis requires at least two separate early-morning, fasting testosterone tests, generally below around 300 ng/dL, alongside consistent symptoms, according to a 2026 statement from the Endocrine Society. A single low reading, or symptoms alone without confirmed lab results, isn’t enough for a proper diagnosis, this is exactly the standard covered in our low testosterone guide.
2. When Properly Prescribed, the Evidence for Benefit Is Genuinely Strong
A recent narrative review found TRT consistently improved sexual desire, erectile function, lean body mass, bone density, insulin sensitivity and overall vitality in men with confirmed hypogonadism, according to research published in PMC. This isn’t a marginal effect in the right candidate, it’s a well-documented, multi-system benefit.
3. Historical Fears About Heart and Prostate Risk Have Been Substantially Reassessed
Older concerns centred on cardiovascular safety and prostate cancer risk. Contemporary, higher-quality evidence has found no increased risk of major cardiovascular events or prostate cancer when TRT is properly prescribed and monitored. Active prostate cancer remains an absolute contraindication, and appropriate screening before starting treatment still matters.
4. Real, Well-Documented Risks Still Require Monitoring
Erythrocytosis, an excess of red blood cells, is the most common dose-related side effect and requires routine blood monitoring. Testosterone therapy suppresses natural sperm production and should be avoided or carefully managed in men actively trying to conceive, covered in more depth in our fertility guide. Fluid retention, acne, and gynaecomastia can occur depending on formulation and dosing.
5. This Is an Ongoing Treatment, Not a One-Time Prescription
TRT requires regular follow-up blood tests, including testosterone levels, blood count, and PSA, to catch side effects early and confirm the treatment is working as intended. A doctor who simply prescribes it once without ongoing monitoring isn’t following appropriate practice.
6. We Refer for This, We Don’t Prescribe It
TRT sits outside a naturopath’s registered scope of practice in South Africa. Where your history and symptoms suggest confirmed hypogonadism might be relevant, we’ll say so directly and support you in getting the right referral to a GP or endocrinologist, who can order proper testing and manage treatment safely if it’s appropriate for you.
A Private Self-Check
A few questions worth reflecting on:
2. Are your symptoms consistent with low testosterone, or could something else explain them?
3. Are you currently trying to conceive, or planning to in the near future?
4. Do you have a personal or family history of prostate cancer that needs discussing first?
5. Would you be comfortable committing to ongoing blood monitoring if you started treatment?
Not a diagnosis, just a way to think through your situation before discussing TRT with a doctor.
Frequently Asked Questions | Testosterone Replacement Therapy Explained
Can I get TRT just because I feel tired or low energy?
No, proper diagnosis requires confirmed low testosterone on repeated blood tests alongside consistent symptoms, not symptoms or a single reading alone.
Does TRT cause prostate cancer?
Current higher-quality evidence hasn’t found increased prostate cancer risk when properly prescribed and monitored, though active prostate cancer remains an absolute contraindication to starting treatment.
Will TRT affect my fertility?
Yes, it suppresses natural sperm production. This effect is usually reversible after stopping, but it needs discussing explicitly with your doctor if you’re trying to conceive.
Can this clinic prescribe TRT for me?
No, TRT sits outside a naturopath’s scope of practice. We can support a referral to a GP or endocrinologist if it looks relevant to your situation.
How often will I need blood tests once on TRT?
Regular monitoring is standard practice, your prescribing doctor will set an appropriate schedule based on your specific treatment and response.
Is TRT the same as anabolic steroid use for bodybuilding?
No, TRT is a medically supervised treatment for confirmed hypogonadism at physiologic doses, distinct from non-medical anabolic steroid use, covered in our separate guide, though both work through related hormonal pathways.
