HRT for Men: Who It's For, Benefits, Risks and Monitoring
Yes, a man can do HRT. For men, hormone replacement therapy almost always means testosterone replacement therapy (TRT), and it is meant for men with a diagnosed testosterone deficiency: compatible symptoms plus consistently low blood testosterone, with other causes ruled out. It is not a general anti-aging or fitness supplement. This guide explains who qualifies, what it can and cannot do, the risks (including fertility), and what proper monitoring looks like in Canada.
TL;DR
Male HRT is testosterone treatment for men with both symptoms and a low morning testosterone result. A low number alone is not enough.
Canadian guidance says treatment can improve deficiency symptoms and quality of life, but no one can reliably predict how much any individual man will feel better.
The main risks are raised red blood cell counts (polycythemia), suppressed sperm production, and prostate findings that need follow-up.
If you want children, standard testosterone is usually the wrong first tool. Ask about fertility-preserving options first.
Good care means baseline and regular blood work, not a prescription and a goodbye.

Can a man do HRT?
Yes, but the reason matters. Men take testosterone when a clinician confirms hypogonadism, meaning the testes are not producing enough testosterone. The Canadian Urological Association (CUA) guideline defines testosterone deficiency by a combination of compatible signs or symptoms, physical findings and low serum testosterone. Symptoms are nonspecific and can have other causes, such as poor sleep, depression, thyroid problems, obesity or medication effects. So the number alone does not make the diagnosis, and neither do symptoms alone.
The same guideline says asymptomatic men with a low result and no effect on quality of life generally should not be given testosterone. There are exceptions where investigation and possible treatment may still be considered, including unexplained anemia or sarcopenia, long-term glucocorticoid or opioid use, and HIV-associated weight loss.
That caution exists for a reason. A CMAJ guideline cites Ontario research finding that only 6% of men over 65 prescribed testosterone had a conclusive diagnosis of hypogonadism. Prescribing without a proper workup is a known problem, and it is the first thing to look for when choosing a clinician.
What “HRT for men” does not mean
You may also see “hormone therapy” used for transgender men, or for men with prostate cancer (where the goal is the opposite: lowering testosterone). Those are separate medical pathways with different goals and different specialists. This article covers testosterone replacement for men with low testosterone.
Signs that deserve a proper assessment
Common reasons men ask about testosterone include:
Reduced sexual desire or erectile difficulty
Persistent fatigue and low energy
Low mood or irritability
Loss of muscle mass or increased body fat
Reduced bone density
None of these proves low testosterone. Each deserves a conversation about sleep, stress, weight, alcohol, medications, diabetes, thyroid function and mental health before a hormone is on the table. If low mood is a big part of the picture, counselling can be a useful part of the plan, whether or not testosterone is also needed.
How low testosterone is diagnosed
The CUA approach, summarized in the research behind this article, starts with compatible symptoms or signs plus a low morning total testosterone. Levels are highest in the morning, so afternoon draws can mislead. When a result is borderline, calculated free or bioavailable testosterone can help clarify. Clinicians should also look for reversible and secondary causes (for example pituitary problems, medications, or obstructive sleep apnea) before starting treatment.
Practical points for your appointment:
Book the blood draw for the morning, as your clinician directs.
Bring a list of every medication and supplement you take.
Expect questions about sleep, mood, sexual function, and whether you want children.
Expect a physical exam and, at some point, baseline blood tests beyond testosterone, including hematocrit and PSA.
Potential benefits
The CUA describes the goals of treatment as improving signs and symptoms of testosterone deficiency, quality of life and serum testosterone. Depending on your symptoms, that can include sexual, physical and structural changes, such as sexual desire, muscle mass and bone health. The popular health content that ranks for this topic, including Alberta’s public health information, describes much the same list: sexual desire, muscle mass and bone loss prevention.
Two honest caveats keep expectations realistic:
According to the CUA, more than 90% of treated men achieve normal blood levels, but there is not enough evidence to predict how many will actually feel better. Numbers and symptoms have to be judged together.
The CUA also cautions that an individual’s symptom response cannot be reliably predicted. A trial with clear checkpoints is the fair way to find out.
Testosterone is also not an approved way to boost athletic performance, strength or appearance in men with normal levels. If your levels are normal, TRT is not a shortcut.
Risks and side effects
The CUA guideline lists the main concerns:
Polycythemia. Testosterone can raise red blood cell concentration, which may be associated with blood clots. This is why hematocrit is checked regularly.
Fertility suppression. More on this below.
Prostate findings. A rise in PSA requires investigation. Monitoring includes PSA and a digital rectal exam.
Cardiovascular risk. The evidence is conflicting, so your personal heart history matters in the decision.
Older reviews, such as this PMC review on testosterone in older men, also describe worsened sleep apnea and gynecomastia (breast tissue growth) as possible effects. Tell your clinician if you snore heavily, stop breathing at night, or have a history of prostate or breast cancer, as these can be contraindications. The CMAJ guideline notes men with a history of breast cancer are not candidates for TRT.
Treatment should be individualized, and the CUA says it should be stopped if contraindications appear or an adequate trial fails.
Fertility: the question to ask first
This is the point most men are never told about early enough. Exogenous testosterone suppresses the pituitary hormones LH and FSH, which can sharply reduce sperm production. According to the CUA, it should not be used alone by men who are actively trying to conceive or who want to preserve fertility.
For those men, the guideline describes off-label approaches that stimulate the body’s own testosterone production rather than replacing it: human chorionic gonadotropin (hCG), selective estrogen-receptor modulators such as clomiphene or tamoxifen, and aromatase inhibitors, with consultation from a male-fertility specialist (CUA guideline PDF). If you want to read about how one of these options compares with another, there is a useful explainer on enclomiphene versus clomiphene for men’s fertility. Whichever route you consider, these are prescription decisions to make with a clinician, not something to source online.
Treatment options and what a target looks like
The CUA lists injectable and transdermal (gel or patch) testosterone among the options, chosen by symptoms, convenience, absorption, adverse effects and monitoring results. Each has trade-offs:
Option | What to know |
Injectable testosterone | Given at set intervals; blood levels swing between doses, so test timing matters |
Gel or other transdermal | Daily application; absorption varies; avoid skin contact with partners or children |
Fertility-preserving alternatives (hCG, clomiphene, others) | Off-label; aim to raise your own production; need fertility-specialist input |
The CUA recommends aiming for the mid-normal range, with a cited total testosterone target of 14 to 17 nmol/L, using the minimum dose that improves symptoms and levels. More is not better.
Monitoring: what responsible follow-up looks like
The CUA guidance is to assess symptoms, adverse effects, testosterone, hematocrit and PSA at baseline, at three months and six months, then yearly. A digital rectal exam is done at baseline and yearly. British Columbia’s provincial testosterone testing protocol gives a similar schedule: repeat hematocrit, PSA and rectal exam at three and six months, then annually if stable.
Timing of the blood draw also depends on your formulation. The same BC protocol specifies:
Injectable enanthate or cypionate: midway between injections, or at trough
Gel or intranasal: 2 to 8 hours after application
Patch: 3 to 12 hours after application
Oral testosterone undecanoate: 3 to 5 hours after a dose taken with a fat-containing meal
If a clinic offers you testosterone without a plan for this follow-up, that is a red flag.
Our perspective: honest recommendations first
At Bloom Society we are a Nurse Practitioner-led clinic, and hormone therapy is one of the services we offer alongside aesthetics and wellness care. Our approach to every hormone conversation is the same as for a filler or laser consult: start with your goals, give an honest recommendation, and do not sell what you do not need. For male hormone questions, that means treating a low number as a reason to ask more questions, not as an automatic prescription.
We lean on medically guided, evidence-based protocols, and the Canadian guidance above is the sort of standard we think any patient should expect: a documented diagnosis, a conversation about fertility before a prescription, and scheduled follow-up blood work. We also see how often hormones, skin, sleep, mood and confidence are tied together, which is why we offer counselling and wellness care in the same place. Not every man who walks in will need testosterone, and when the honest answer is “not yet” or “see a different specialist,” we will say so. If you are curious how we think about hormone therapy for women, our piece on compounded bioidentical HRT and side effects shows the same questions-first approach.

If you are also interested in skin care, our dermaplaning for men is a simple, low-commitment treatment that many men start with.
What to bring and ask at your first visit
A short checklist makes the appointment far more productive:
A written timeline of your symptoms and when they began
Any previous blood work, especially past testosterone, PSA or hematocrit results
Your family history of prostate cancer, blood clots and heart disease
Whether you plan to have children in the next few years
Questions such as: Which causes will we rule out first? How will we define success? When will we stop if it is not working?
Those last two questions matter. A well-run trial has a defined point to review and a clear plan to stop if the benefit is not there.
FAQ
Can a man do HRT?
Yes, if he has a confirmed testosterone deficiency: compatible symptoms plus low morning testosterone, with other causes considered. Canadian guidance does not generally recommend treatment for a low result alone without symptoms. A clinician should also review your fertility plans and medical history first.
What are the potential side effects of TRT?
The main ones are polycythemia (raised red blood cell concentration), reduced sperm production, and PSA rises that need investigation. Evidence on cardiovascular risk is conflicting. Regular blood tests and exams are how these are caught early.
What are the treatment options for male hypogonadism?
Injectable and transdermal testosterone are the main options, chosen by symptoms, convenience and monitoring results. Men who want to preserve fertility are usually referred for approaches that stimulate their own production, such as hCG, clomiphene or aromatase inhibitors, which are used off-label.
What are the benefits of testosterone therapy?
Potential benefits include better sexual desire, muscle mass, bone health, quality of life and normalized blood levels. Response varies, and the CUA notes it cannot be reliably predicted, so symptoms and lab results are reviewed together over time.
