Infertility clinical trials in California
We’re tracking 10 recruiting infertility studies with a site in California — including Phase 1/Phase 2, Phase 3 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT07216742RecruitingPhase 3
Study of a fertility drug for women undergoing IVF with frozen embryo transfer
This trial tests a medication called human menopausal gonadotropin to help women undergoing IVF achieve a live birth. It focuses on the cumulative success rate after freezing and later transferring embryos.
Encino, CaliforniaAges 18–42 - NCT07611448Enrolling by invitation
AI Tool to Help Select the Best Embryo for Pregnancy
This study tests whether artificial intelligence can better identify which embryos are most likely to result in a successful pregnancy during fertility treatment. Researchers will use an AI system to analyze embryo images on days 5–7 of development to help doctors choose the best embryo to transfer.
Clovis, CaliforniaAges 18–45 - 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.
Stanford, CaliforniaAges 18 years+ - NCT06701071RecruitingPhase 4
Comparing short vs long Clomid for IVF stimulation
This study tests whether a shorter or longer course of Clomid (a fertility medicine) works better for women who are expected to have a low response to ovarian stimulation. It may help those with a lower egg reserve still produce enough eggs for IVF.
Pasadena, CaliforniaAges 18–44 - NCT03011684RecruitingPhase 3
Preserve eggs using tamoxifen and letrozole during new breast cancer treatment
This study tests whether taking tamoxifen and letrozole (with fertility injections) can help people with newly diagnosed, estrogen-sensitive breast cancer preserve eggs before cancer treatment starts. It may help protect future fertility by collecting eggs early, before chemotherapy or other treatments begin.
San Francisco, CaliforniaAges 18–50 - NCT05951075Recruiting
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.
Encino, CaliforniaAges 18–50 - NCT06841861RecruitingPhase 1/Phase 2
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.
San Francisco, CaliforniaAges 18–60 - NCT00628199Enrolling by invitation
Skin sample study to create future cell therapies
This study collects skin cells from people with certain long-term conditions (or specific genetic disorders). Researchers use the cells to try to build new treatments for human disease and disability in the future.
Stanford, CaliforniaAges 1–75 - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+ - NCT03825120Enrolling by invitation
Study following ovarian aging and heart risk
This study follows people who were already enrolled in the original OVA study, to track how ovarian aging may affect long-term heart health. It can help doctors understand which risks change over time and why.

What taking part in a 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.

Common questions
- Are there infertility clinical trials in California?
- Yes. We're currently tracking 10 recruiting infertility studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a infertility study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a infertility trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New infertility studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
