Recruiting studies
- NCT07375238Recruiting
Gazpacho daily for better sperm health
This study tests whether drinking gazpacho daily can improve sperm quality and reduce stress in the body. It may help men with low or abnormal sperm counts.
Madrid, MadridAges 18–45 - NCT05410782Recruiting
Prenatal supplements to improve sperm quality
This study tests whether a prenatal supplement for men can improve sperm quality in people trying to conceive. It focuses on improving semen results when there is low count, weaker movement, or abnormal shape.
Mississauga, OntarioAges 18–45 - NCT06950203Recruiting
Fish oil supplement for sperm quality
This study tests whether a special fish oil supplement (EPAX EVOLVE 05) can improve sperm movement in men with low sperm motility. It may help if you have been told your sperm are not moving well and you are willing to take a sperm test.
OsloAges 18–55 - NCT06742437Recruiting
Study of a new sperm preparation method
This study tests a new method for preparing sperm to help with fertility treatments. It is for men who can provide a semen sample and have no active infections or history of certain viruses.
Barcelona, BarcelonaAges 18–60 - NCT04959864Recruiting
Food supplement study for sperm DNA damage in men
This trial tests whether a daily food supplement (with myo-inositol, N-acetyl-cysteine, zinc, and vitamins) can reduce sperm DNA damage. It enrolls men with higher-than-normal sperm DNA fragmentation, and it checks semen health during the study.
ParisAges 20–45 - NCT06561451Recruiting
Comparing two IVF methods for severe sperm shape issues
This trial compares two lab techniques (ICSI alone vs. ICSI with AOA) to see which leads to more live births for couples where the male partner has very abnormal sperm shape (99-100% abnormal). The study focuses on women aged 20-37 who are undergoing fertility treatment.
ShanghaiAges 20–37 - NCT05903859RecruitingPhase 3
Study to improve fertility in men after spinal cord injury
This phase 3 study tests a treatment to improve reproductive function (fertility-related measures) in men who have had a traumatic spinal cord injury. If you may be eligible, it could help researchers see whether the treatment improves reproductive outcomes for men with spinal cord injury.
Miami, FloridaAges 18 years+ - NCT04452305Recruiting
Frozen testicle tissue transplant to restore fertility
This study tests using previously frozen (cryopreserved) testicle cells or tissue to regrow testicular tissue. If you’ve had cancer treatment that can harm fertility, this may help restore natural fertility potential using your own tissue.
Pittsburgh, PennsylvaniaAges Any age - NCT02641769RecruitingPhase 1/Phase 2
Stem cell injection into testicles for infertility
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.
Amman, Amman GovernorateAges 21–50 - NCT07814235Recruiting
Freezing sperm as a way to protect quality as men age
This study is looking at whether freezing sperm can protect the quality of sperm as men age. If you join, you'll provide samples for research, and the findings could help men plan for future fertility.

Common questions
- Are there clinical trials for male infertility?
- Yes. Clin2 currently lists 34 recruiting male infertility studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a male infertility trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a male infertility trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
