Prednisolone to prevent unexplained recurrent miscarriages
This trial tests whether a medicine called prednisolone can help prevent further miscarriages in people who have had recurrent miscarriages with no known cause. If you qualify, you would take prednisolone early in pregnancy and the study team would watch whether more losses occur.
Leiden, South HollandAges 18–40 - NCT05750849Recruiting
Checks progesterone levels to predict pregnancy in fertility treatment
This study looks at whether a blood progesterone level around the time of a pregnancy test during fertility treatment helps predict which patients will have an ongoing pregnancy. It may help doctors better understand who is most likely to continue developing a pregnancy during artificial cycles.
Valencia, ValenciaAges 18–50 - NCT05756244Recruiting
Managing blood thinners during pregnancy to prevent clot problems
This study looks at the best way to manage blood thinners (like injections of LMWH) during pregnancy for people who need them because of a past or current blood clot risk. It may help by improving how safely and effectively anticoagulation is handled to reduce clot complications.
Durham, North CarolinaAges 18–60 - NCT05756023Recruiting
IVF and ICSI outcomes in women with PCOS
This trial studies how IVF (fertility treatment) and ICSI (a lab step used with IVF) work in women with PCOS. It may help doctors understand which PCOS-related factors affect success and how to tailor care.

Teen study following mothers from an earlier pregnancy project
This study follows teenagers whose mothers took part in an earlier lifestyle-in-pregnancy study (started in 2007–2010). It may help researchers understand how that earlier study relates to teen health and development.
OdenseAges 13–65 - NCT05780099Recruiting
Study of patients treated in internal medicine clinics
This observational study follows people receiving care in Internal Medicine at San Raffaele Hospital to better understand what kinds of conditions they have. It does not test a new treatment, but your information may help improve future care.

Study of Spinraza in pregnancy for 5q spinal muscular atrophy
This study looks at how Spinraza (nusinersen) taken during or before pregnancy affects people with 5q spinal muscular atrophy (SMA) and the health of their babies. It mainly fits those who were pregnant and received Spinraza around the time of conception or during pregnancy.
Palo Alto, CaliforniaAges 18–54 - NCT05807594Recruiting
Online program to help manage weight gain during pregnancy
This trial tests an at-home (online) coaching program to help pregnant people gain weight at a healthier rate. It may help you stay on track during pregnancy and understand what changes work best for you.
University Park, PennsylvaniaAges 18–45 - NCT05838404Recruiting
Program to support mental health during early pregnancy
This study tests an intervention meant to improve mental health for people during pregnancy, starting in the first part of pregnancy. You might be able to join if you are already receiving prenatal care and speak English or Spanish.
New Orleans, LouisianaAges 18 years+ - NCT05885971Recruiting
Screening for eating disorders during pregnancy
This study looks at ways to detect eating disorders in pregnant women. It may help doctors identify concerns earlier and offer support sooner during pregnancy.
PoitiersAges 18 years+ - NCT05888467Recruiting
Exercise study for women at risk of pregnancy heart problems
This study looks at how physical activity affects the heart and blood-vessel health “profile” in women who have risk factors for a pregnancy condition (called GHD, related to preeclampsia risk). It may help researchers find safer or more helpful activity guidance before pregnancy.
Diepenbeek, LimburgAges 18–50 - NCT05910580Recruiting
Screening and support for alcohol and substance risk in adults
This study aims to improve care access and outcomes for adults who screen positive for risky alcohol or drug use. If you qualify, you may be offered ways to connect to support during your reproductive years.
Boston, MassachusettsAges 18 years+ - NCT05935904Recruiting
Tracking how pregnancy changes metabolic risk markers
This study follows pregnant women to see how common metabolic health markers (like blood sugar, cholesterol, blood pressure, and belly size) change during pregnancy. It may help doctors better understand who is at higher risk for complications during pregnancy.
JimmaAges 18–45 - NCT05952583Recruiting
Study of growth-restricted twin babies in shared placenta
This study looks at babies in monochorionic (shared-placenta) twin pregnancies where one or both babies are growing too slowly. It aims to better understand this condition and follow families over time to improve care, with check-ins through age 2 after birth.
Boston, MassachusettsAges 18–50 - NCT05968794Recruiting
Cervix stitch to help twin pregnancy with short cervix
This study tests whether placing a “cervix stitch” (cerclage) can reduce the risk of very early birth in twin pregnancies. It is for people whose cervix is shorter than expected or has started to open before 24 weeks.
AntwerpAges 16 years+ - NCT05969795RecruitingPhase 1
Natural embryo transfer with or without progesterone support
This Phase 1 study compares pregnancy outcomes, especially live birth, when using a natural-cycle frozen embryo transfer with an embryo that is genetically euploid (normal chromosome number) versus doing transfers without luteal (progesterone) phase support. It may help determine whether adding progesterone around ovulation improves the chance of a live birth.
Abu DhabiAges 18–40 - NCT05977686Recruiting
Hemoglobin testing in pregnant adults
This trial studies how hemoglobin (an oxygen-carrying protein in blood) is checked during pregnancy. It may help improve or confirm the best way to monitor blood health in pregnant patients.
Washington D.C., District of ColumbiaAges 18–50 - NCT06001450Recruiting
Plastics and toxins in pregnant women and families

Late cerclage for preventing early birth in high-risk pregnancies
This trial tests if placing a stitch in the cervix (cerclage) between 24 and 27 weeks of pregnancy can help prevent preterm birth in women whose cervix is short. It may be an option for those who find out late in pregnancy that they are at risk.
Charlotte, North CarolinaAges 18–50 - NCT06048510Recruiting
New blood markers to predict pregnancy diabetes and large babies
This study tests if new blood markers can help predict gestational diabetes and the risk of having a large baby. It could lead to earlier detection and better care.
