Which countries run stem-cell trials for Erectile Dysfunction?

Country distribution

A study with sites in several countries is counted once per country, taken from the location block of each registry record.

What the map means for Erectile Dysfunction

Registered work is scattered across urology departments in a handful of countries, while the commercial market is dominated by clinics selling packages that bundle injections with shockwave therapy. The absence of a country from the trial map says nothing about how many clinics there advertise the service.

Where recruitment is actually open

What travelling for a trial actually involves

If a site is abroad, the practical questions are who provides follow-up at home, what happens if an adverse event occurs after you fly back, and whether the protocol permits remote assessment at all. Most do not.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

No sampled study for this condition lists sites in more than one country, so the research base here is made of single-centre work rather than multinational collaboration.

Why trial geography is not a shortlist

Trial locations follow regulation, funding and sponsor headquarters, not clinical quality. Countries with clear conditional pathways for advanced therapies and large public research budgets register more studies. A country appearing here also says nothing about whether commercial clinics there operate under the same oversight as the registered trials.

Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.

When these studies started

Registrations by start year since 2020: 2020 (3), 2021 (1), 2022 (1), 2024 (4), 2025 (3), 2026 (2). Activity for this condition spans 2010 to 2026, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Erectile Dysfunction?

Sites are registered in 16 countries; the largest is United States (~28% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

No — trial counts describe where research is permitted and paid for. Care quality is decided at the level of the individual provider and product.

Are trial sites and commercial clinics the same thing?

They are generally distinct. Proximity in a city or even a shared address does not make a commercial clinic part of a registered protocol — ask for the identifier.
