What recruiting does and does not mean
A recruiting flag says a protocol cleared ethics review and enrolment is open. It says nothing about earlier results, nothing about your eligibility and nothing about price, because trials are not a purchase channel. Stale flags are common, so contact the listed coordinator rather than trusting the status field.
Sites sit in 10 countries, led by Egypt. Travelling for a trial rarely works unless the site has confirmed in writing that it can enrol non-residents and fund the follow-up schedule.

Frequently asked
How many stem-cell trials for Male Infertility are recruiting right now?
4 of 15 registered records (2026-08-29).
Can I join one of these trials?
That depends entirely on the written criteria — age, disease stage, prior treatment and often geography. The site's study coordinator is the only reliable source on current capacity.
Do trials charge participants?
Participants are not usually billed for the study product. A five-figure invoice attached to a supposed trial place means you are buying a treatment, not joining research.
