Recruiting studies
- NCT06182878Recruiting
Supportive care for recurrent pregnancy loss
This study explores a new supportive care program for people who have had multiple pregnancy losses and are pregnant again. It aims to see if extra attention and care can help reduce the risk of another loss.
Bethesda, MarylandAges 18–44 - NCT05510622Recruiting
Uterine microbiome study for recurrent pregnancy loss
This study looks at the normal bacteria and other microorganisms in the uterus to better understand recurrent pregnancy loss. You may be in a group with recurrent pregnancy loss or in a comparison group without pregnancy loss, and you’ll be asked to meet specific health and timing rules for samples.

This study looks at genes and gut bacteria in women who have had repeated miscarriages without a known cause. It aims to find possible reasons for these losses and could help improve future care.
Porto Alegre, Rio Grande do SulAges Any age - NCT07325370Recruiting
Brain training with feedback for anxiety in pregnancy loss
This trial tests if a non-invasive brain training method (neurofeedback) can help women with recurrent pregnancy loss who also have anxiety. It aims to improve heart rate regulation and reduce anxiety using a closed-loop system that gives you real-time feedback.

Recurrent Pregnancy Loss Registry
This study is a registry for people who have had repeated pregnancy losses. It will collect information to better understand and help manage this condition.
Vancouver, British ColumbiaAges 15–49 - NCT07233278Recruiting
Brain stimulation for anxiety after miscarriages
This study tests a non-invasive brain stimulation technique (repetitive TMS) to see if it can improve heart health and reduce anxiety in women who have had multiple pregnancy losses and struggle with anxiety. You will receive high-intensity, low-frequency magnetic pulses over a specific area of the brain involved in worry and stress.
Shenyang, LiaoningAges 18–45 - NCT06408181RecruitingPhase 3
Aspirin to prevent pregnancy loss and preeclampsia
This study tests whether taking a daily low-dose aspirin can help prevent pregnancy loss and preeclampsia. It's for women who are in early pregnancy and have certain health risks.
Philadelphia, PennsylvaniaAges 18–45 - NCT07358026Recruiting
Early pregnancy study: health before conception
This study follows women and their partners before pregnancy to understand how health before conception affects early development. It is for people planning a pregnancy who are generally healthy.
ChiguayanteAges 18–40 - NCT07759609Recruiting
Intrauterine insemination after pregnancy loss
This study tests whether intrauterine insemination (IUI), a simple procedure where sperm is placed directly into the uterus, improves the chance of a successful pregnancy for couples who have had at least one unexplained miscarriage. It aims to help couples who are trying again within a year of their loss.
Beijing, Beijing MunicipalityAges 20–37 - NCT05798494Recruiting
Pre-pregnancy weight loss plan to protect child weight
This study tests whether a very low-calorie weight loss program before pregnancy can improve the chance that a child will have a healthier weight later. It follows families and stores samples from the child at home.
AarhusAges 18–38 - NCT07143578Recruiting
Comparing two surgeries for early pregnancy loss after IVF
This trial compares two surgical methods (suction curettage vs. hysteroscopy) for removing early pregnancy tissue in women who conceived through IVF, to see which is safer and has fewer side effects.
Be’er Ya‘aqovAges 18–50 - NCT07414511Recruiting
Hemophilia A research study for pregnant families
This study follows pregnant people who carry a severe hemophilia A gene and their babies after birth. It looks at how hemophilia A is passed down and how it affects families, with the goal of improving understanding and care.
Seattle, WashingtonAges Any age - NCT07532629Recruiting
How Gut Bacteria Affect IVF Success in Couples
This study examines how the bacteria in your gut and your partner's gut may affect the success of IVF (in vitro fertilization) treatment. Researchers will collect samples and health information from couples before IVF to see if certain bacterial patterns predict better pregnancy outcomes.
MalmöAges 18–40 - NCT05127252Recruiting
Study how gut bacteria may affect time to pregnancy
This study looks at whether differences in the gut (microbiome) are linked to how long it takes to get pregnant and pregnancy outcomes. It may help researchers understand who might benefit from future microbiome-focused approaches.
Stockholm, HuddingeAges 18–40 - NCT06802874Recruiting
Genital bleeding in pregnancy after 18 weeks
This trial studies outcomes for pregnant women who have genital bleeding after 18 weeks. It aims to understand how bleeding affects both mother and baby.
Bologna, BolognaAges 18–45 - NCT03775954Recruiting
Fetal heart testing in high-risk pregnancies after baby loss
This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.
Madison, WisconsinAges 18 years+ - NCT06518928Recruiting
AI sperm selection for IVF with ICSI
This trial tests an artificial intelligence system that helps select the best sperm for use during IVF with ICSI. The goal is to see if this improves fertilization, embryo development, and reduces early pregnancy loss.
Las Vegas, NevadaAges Any age - NCT06652113Recruiting
Hydroxychloroquine with thyroid hormone for recurrent pregnancy loss
This study tests whether a combination of hydroxychloroquine (an anti-inflammatory drug) and levothyroxine (thyroid hormone) can improve live birth rates in women with recurrent pregnancy loss, normal thyroid function, and TPO antibodies.
Guangzhou, GuangdongAges 20–40 - NCT07724405RecruitingPhase 2
G-CSF for Unexplained Recurrent Miscarriage During IVF
This study tests whether G-CSF (a medicine that helps the immune system) given during IVF can reduce miscarriages in women who have had repeated pregnancy losses with no clear reason.
Abu DhabiAges 18–44 - NCT07639333Recruiting
Understanding Early Pregnancy Loss Through Genetic Testing
This study examines genetic material from miscarriages to understand why early pregnancy loss happens. Researchers analyze a blood sample taken right after miscarriage to look for clues that might help explain what went wrong and potentially prevent future losses.
RennesAges 18–43 - NCT07542600Recruiting
Spa therapy to help women with infertility after embryo transfer
This study tests whether spa-based rehabilitation—including thermal water treatments and relaxation therapies—may improve fertility outcomes in women who have had unsuccessful embryo transfers. Researchers hope it might help prepare the body for pregnancy.
Františkovy Lázně, Carlsbad RegionAges 20–40 - NCT05169541Recruiting
Testing a blood marker in repeated pregnancy loss
This study looks at whether a blood protein level called mannose binding lectin is linked to why some people have repeated pregnancy loss or unsuccessful embryo transfers. If you’ve had multiple losses or failed transfers, the study may help clarify biology behind reproduction and could guide future care.
AarhusAges 18–41 - NCT05557201Recruiting
Study causes of repeated early miscarriages
This study looks at people who have had repeated early pregnancy losses to find patterns that might explain why miscarriages keep happening. It mainly involves collecting and analyzing your medical information to better understand risk factors.

Common questions
- Are there clinical trials for pregnancy loss?
- Yes. Clin2 currently lists 30 recruiting pregnancy loss 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 pregnancy loss 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 pregnancy loss 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.
