What is Testosterone replacement and what is it used for?

Testosterone replacement is a treatment related to sexual health. Hi Doctor does not prescribe it today, but our EU-licensed doctors can review your case and propose sexual health alternatives with robust clinical evidence and EU regulatory approval.

Why does Hi Doctor not prescribe Testosterone replacement?

Our doctors only prescribe treatments with robust clinical evidence, an EU-approved indication and a reviewed safety profile. Testosterone replacement is not on that list today. It may be investigational, not approved, or outside the scope of what we handle via telemedicine.

What alternatives can I consider within sexual health?

Our doctors review your history and propose the most appropriate treatment among those authorised in the EU for sexual health. The consultation fee for each area is listed on our pricing page. If your case is not eligible, the applicable fee is refunded.

How would my sexual health consultation work?

You fill in an online medical questionnaire (~4 min). An EU-licensed doctor reviews it and replies in less than 2 hours on average via the private chat in your account. If eligible, they issue an electronic prescription; each pharmacy decides whether it can dispense it.

Can I switch from Testosterone replacement to a treatment the doctor can prescribe?

Often, yes. Tell the doctor in the questionnaire that you have used Testosterone replacement, for how long and how it went. The doctor decides whether one of the sexual health treatments authorised in the EU is appropriate for you and, if it is, explains how to move from one to the other safely.

Is it safe to use Testosterone replacement without a doctor's supervision?

No prescription medicine should be used without a doctor who knows your health and your other medicines. Products sold without a prescription online may be counterfeit or wrongly dosed. If you are already using Testosterone replacement, keep your prescriber informed and report any side effect.

What should I tell the doctor if I have used Testosterone replacement before?

The dose, how long you took it, whether it helped, any side effects and why you stopped. Add your other medicines, allergies and relevant conditions. This lets the doctor judge which sexual health option, if any, is appropriate and safe for you.

What happens if the doctor decides no treatment is appropriate?

The doctor explains why in your private chat and, where it helps, what to do next, for example seeing your own doctor or a specialist in person. The consultation fee is refunded in full when the doctor cannot approve treatment.

Can I get a consultation for Testosterone replacement from Pilsen?

Yes. Hi Doctor runs 100 % online across the EU, so if you live in Pilsen you can fill in the questionnaire and receive the medical review without travelling. The EU-licensed doctor issues the electronic prescription under Directive 2011/24/EU, and each pharmacy decides whether it can dispense it; outside Spain, some pharmacies do not accept PDF prescriptions, and those that do dispense the locally marketed equivalent of the same active ingredient.

Is my sexual health consultation fully confidential?

Yes. All communication happens in the private chat of your account, GDPR-compliant. The doctor treats discretion as a core of the service and there is no history visible outside your consultation.

What is the private electronic prescription and which pharmacies can dispense it?

The private electronic prescription (Receta Médica Privada Electrónica) is issued by an EU-licensed doctor. It is a PDF carrying every field required by EU Directive 2011/24/EU (patient, prescriber with country of registration, active ingredient, dose). Each pharmacy decides whether it can dispense it. In Spanish pharmacies it is dispensed from the QR; outside Spain, some pharmacies do not accept PDF prescriptions, and those that do dispense the locally marketed equivalent of the same active ingredient.

How does Hi Doctor work step by step?

1) Fill in an online medical questionnaire in about 4 minutes. 2) The consultation fee for each area is listed on our pricing page. 3) An EU-licensed doctor reviews your case and, if appropriate, issues an electronic prescription. 4) Collect it at the pharmacy you choose; each pharmacy decides whether it can dispense it. If the review is not approved, the applicable fee is refunded in full.

How much does it cost and what does the price include?

The consultation fee for each area is listed on our pricing page. Each includes a review by an EU-licensed doctor and an electronic prescription if approved. If the review is not approved, the applicable fee is refunded in full. Medication is paid for separately at the pharmacy at the price it sets.

IN PLAIN TERMS

What Testosterone replacement is, and what to know

Testosterone replacement therapy, often shortened to TRT, is a hormone treatment given as a gel, patch or injection for men whose bodies genuinely do not make enough testosterone, a condition called hypogonadism. Testosterone medicines are authorised across EU countries, but only for that diagnosis: European regulators require low testosterone to be confirmed by both symptoms and blood tests before treatment starts, and they require haemoglobin, liver function and blood fats to be checked regularly while it continues. It is not authorised as a lifestyle, anti-ageing or performance treatment, and it is not an erectile dysfunction medicine. Hi Doctor does not prescribe testosterone online on demand, because starting it needs repeat blood tests, a physical assessment and long-term follow-up that an online questionnaire cannot replace; if the problem you actually want help with is erections, that is a separate conversation with a doctor.

Testosterone replacement is an authorised medicine in the EU, so an EU-licensed doctor can prescribe it when it is clinically appropriate for you.

Can I get it?

Yes, if a doctor decides it is right for you. Testosterone replacement is authorised in the EU and can be prescribed after a medical review.

What can I take instead?

VERIFIED EVIDENCE

Testosterone replacement: evidence and regulatory guide.

WHAT IT IS

How it works

Testosterone replacement tops up the body's own supply of the hormone when the testicles or the glands controlling them are not making enough, and the hormone then acts on androgen receptors in muscle, bone, brain and sexual tissue.

DOSE OR GROUP	MEAN WEIGHT CHANGE	WEEKS
Testosterone gel for 1 year, men aged 65+ with testosterone below 275 ng/dL	Significantly increased sexual activity on the Psychosexual Daily Questionnaire (P<0.001), with significantly increased sexual desire and erectile function	52
Testosterone gel for 1 year, Sexual Function Trial (n=470)	10 of 12 measures of sexual activity improved compared with placebo; no threshold testosterone level was identified for any outcome	52

These results come only from men aged 65 and over whose low testosterone was confirmed by blood tests; they say nothing about men with normal testosterone levels, and the trial authors state the study was too small to draw conclusions about the risks of treatment.

NAMED SAFETY SIGNALS

What has been reported with Testosterone replacement.

Major cardiac events

In TRAVERSE a first cardiovascular death, non-fatal heart attack or non-fatal stroke occurred in 182 men on testosterone (7.0%) and 190 on placebo (7.3%); hazard ratio 0.96, 95% CI 0.78 to 1.17, meeting the trial's non-inferiority criterion.

Irregular heartbeat, kidney injury and blood clots in the lung

TRAVERSE reported a higher incidence of atrial fibrillation, acute kidney injury and pulmonary embolism in the testosterone group than in the placebo group.

Only authorised where deficiency is confirmed

After an EU-wide review that opened on 10 April 2014 and closed with the CMDh position of 8 January 2015, product information was changed to state that testosterone should only be used when an abnormally low hormone level has been confirmed by signs and symptoms and by appropriate laboratory tests. The EMA states that restoring levels in healthy older men is not an authorised use.

Ongoing monitoring required

The same EU review requires prescribers to monitor haemoglobin, liver function and blood lipids regularly during treatment, and added warnings for patients at increased cardiovascular risk.
