Recruiting studies in California
- NCT05479474Recruiting
PRP treatment study for men with testicular infertility
This trial studies whether platelet-rich plasma (PRP) can improve fertility in men with a specific cause of infertility called NOA who have not had success with prior procedures. It may help improve the chance of getting usable sperm for conception.

Testicular organoid study for male fertility
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.

Power prenatal vitamins study for men with specific sperm results
This study looks at whether a specific “power” prenatal vitamin helps improve sperm measures in men whose at-home sperm test results fall in a certain range. It’s mainly for men living in the US or Canada who aren’t taking other prenatal vitamins already and don’t have known causes of male infertility.

What taking part in a male infertility study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
