Stem cell injection into testicles for infertility
Part of Kidney & urinary clinical trials.
This trial tests whether injecting your own stem cells into your testicles can help your body start producing sperm. It is for men whose infertility is caused by a sperm-making problem rather than a blockage.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a man with infertility due to not having sperm in your semen.
- The cause is not a blockage in your tubes, but rather a problem with how your testicles make sperm.
- You have not had any surgery on your testicles in the past.
- You do not have any genital infections or structural problems in your reproductive tract.
- You do not have major medical problems like cancer, and you do not have certain genetic abnormalities (like Y chromosome deletions).

This trial tests if fixing a varicocele (an enlarged vein in the scrotum) helps men who have no sperm in their ejaculate. The goal is to see if sperm can then be retrieved directly from the testicle for use in fertility treatments.
This study looks at a procedure that removes sperm directly from the testicles to help with IVF when a man has no sperm in his ejaculate. It may help couples try for pregnancy when standard semen samples don’t contain sperm.
This trial uses tiny lab-grown testicles to study sperm production. It may help men with infertility learn more about why they can't make sperm.
This study tests a regenerative stem cell therapy to improve fertility in men with testicular failure or low sperm count and women with early ovarian failure. It is for people who have already tried standard treatments without success.
This trial tests whether transplanting frozen testicular tissue that was saved before cancer treatment can help men who cannot produce sperm have biological children. The tissue is thawed and put back into the testicles to restore natural sperm production.
This trial studies a special lab procedure where selected immature sperm cells are injected to help infertile couples achieve pregnancy. It is designed for couples where the man has a specific type of sperm-making problem found during a testicular sperm extraction.
