- NCT01134770Enrolling by invitation
Study of how pregnancy drug exposure affects newborn response
This study looks at how certain exposures during pregnancy can affect a baby’s early physical and brain responses. It may help researchers understand what differences to expect and how early changes can be measured.
Chapel Hill, North CarolinaAges 18–45 - NCT01944332Recruiting
Gamete treatment for failed fertilization in IVF or ICSI
This study looks at a treatment given to egg and sperm (gametes) when fertilization fails during standard IVF or after one ICSI attempt. If fertilization has not worked well before, this trial may test an approach to improve the chances of fertilization.
New York, New YorkAges 21–89 - NCT05588245Recruiting
Community support to help pregnant people during prenatal care
This study tests a community-based support program (“patient navigation”) to help pregnant people with unmet social needs get the care they need. It includes support from early pregnancy through 12 months after delivery and may help if social needs are affecting your prenatal care.
Atlanta, GeorgiaAges 18 years+ - NCT05254041Recruiting
Testing suction to help remove an IUD with a menstrual cup
This study looks at whether gentle suction can help safely remove an IUD when using a menstrual cup at the same time. It may help if your IUD needs removal, and the researchers are testing a specific removal method.
Denver, ColoradoAges 18–45 - NCT05206682Recruiting
Treating C-section scar defect with hormones versus surgery alone
This trial compares two treatments for a pregnancy-related problem in the uterus: vaginal repair alone versus vaginal repair plus leuprorelin (a hormone medicine). It aims to improve symptoms like long or heavy bleeding when a C-section scar defect is also linked with adenomyosis.
Shanghai, Shanghai MunicipalityAges 18–50 - 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.
Ho Chi Minh City, Ho Chi Minh CityAges 18–38 - NCT04891510Recruiting
Compare fat grafting products in breast surgery
This trial compares three methods for moving your own fat into the breast during breast surgery. It may help improve how well fat grafting works and how surgeons choose the best method for you.
New York, New YorkAges 18 years+ - NCT05164926Recruiting
St. John’s wort oil massage during vaginal childbirth
This trial studies whether using St. John’s wort oil for perineum massage (the area between the vagina and anus) during active labor can be helpful for women planning a vaginal birth. It looks at normal, low-risk pregnancies to see what difference this comfort-and-care approach may make.
Ankara, ÇankayaAges 18–40 - NCT04786587Recruiting
Study of alcohol reporting during pregnancy
This study looks at how alcohol use is reported during pregnancy. It may help improve how pregnant people share this information during prenatal care.
LilleAges 18 years+ - NCT01219335Recruiting
Study of discarded medical materials
This study looks at discarded leftover medical materials. There are no listed eligibility limits, so it may be open to many people depending on what materials and consent are needed.
Basking Ridge, New JerseyAges 18–65 - NCT05027828Recruiting
Blood test may track ovarian cancer treatment response
This study checks whether a blood test (ctDNA) can show how well ovarian, fallopian tube, or primary peritoneal cancer treatment is working. If the test reliably reflects response, it could help doctors adjust treatment earlier and more precisely.
ShanghaiAges 18 years+ - NCT05098171RecruitingEarly Phase 1
Study TIL cell therapy for advanced gynecologic cancers
This early-phase study tests GC201 TIL therapy, made from your tumor’s immune cells (TILs), for advanced or returning gynecologic cancers. If standard treatments have already failed—or there aren’t standard options—this trial may offer a new way to train your immune system to fight the cancer.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04697823Recruiting
Hyaluronan added to IVF fluid to help ongoing pregnancy rates
This study tests whether adding hyaluronan (a substance found naturally in the body) to IVF lab fluid can help more people achieve a pregnancy that is still ongoing after treatment. It is focused on people having a second or third egg retrieval after not becoming pregnant previously.
LeuvenAges 18–40 - NCT04169451Recruiting
Letrozole with IUI versus natural cycle IUI
This study compares two ways of timing intrauterine insemination (IUI)—using letrozole medicine to help schedule ovulation versus using a natural (untreated) cycle. It may help couples who are trying to conceive with mild or “unexplained” infertility see which approach works better for pregnancy chances.
Beijing, Beijing MunicipalityAges 20 years+ - NCT04109846Recruiting
Embryo transfer using aneuploid or mosaic embryos during pregnancy
This trial looks at pregnancy and baby outcomes when embryos that have chromosome differences (aneuploidy or mosaic embryos) are transferred, especially when no other embryos are available. It may help people understand the risks and expected outcomes in situations where options are limited.
Sunnyvale, CaliforniaAges 18–55 - NCT04161664RecruitingPhase 2
Chemo for metastatic vulvar cancer with carboplatin and paclitaxel
This trial studies how well carboplatin plus paclitaxel chemotherapy works for vulvar squamous cell cancer that has spread. It may help shrink tumors and control cancer growth in people who are not able to be fully treated with local surgery.
AmsterdamAges 18 years+ - NCT04661072Recruiting
Study genes and cancer risk in uterine birth differences
This study looks at how genetic factors and environment may relate to cancer risk in people with uterine birth differences. It also aims to improve clinical care by learning what patterns show up in real-world patients.
New Haven, ConnecticutAges 13 years+ - NCT04619524Recruiting
Blood and lining tests during IVF cycles to guide endometrial timing
This study looks at “biomarkers” (test signals in your blood or cycle data) to better judge how ready the womb lining is during IVF. It compares two types of IVF hormone setups to see which approach best matches endometrial receptivity and supports successful embryo transfer.
Brno, South MoravianAges Up to 36 years - NCT04560543Recruiting
Laparoscopic support after simple hysterectomy
This study looks at whether adding laparoscopic “support” after a planned hysterectomy can help prevent future pelvic organ prolapse or related problems. You may be eligible if you are having a specific type of hysterectomy and meet several medical and practical requirements.
BernAges 18 years+ - NCT04017286Recruiting
Pregnancy mental health survey and baby development outcomes study
This study looks at how a pregnant person’s mental well-being during pregnancy relates to their child’s later behavior and development. It mainly involves questionnaires and comparing outcomes, and it may help researchers understand what pregnancy mental health supports best.
Chongqing, Chongqing MunicipalityAges 3 months–6 years - NCT04025047Recruiting
Follow-up study after trans-vaginal mesh pelvic surgery
This study follows people who have pelvic reconstructive surgery using a trans-vaginal mesh to learn about possible complications over time. It may help improve care by tracking outcomes for up to 36 months.
Beijing, Beijing MunicipalityAges 18 years+ - NCT03981653Recruiting
Placenta study around normal third-trimester pregnancy
This study looks at how the placenta is working in pregnancies that are planned for cesarean delivery after at least 37 weeks. Researchers compare different pregnancy situations (including some common complications) and check placenta function to better understand placental health.
CréteilAges 18 years+ - NCT03992729Recruiting

This study follows pregnant people who took tildrakizumab to understand pregnancy outcomes and safety. It also compares them with pregnant people with the same underlying disease who did not take tildrakizumab during this pregnancy.
San Diego, CaliforniaAges Any age - NCT04049604Recruiting
Study of pregnancy cancer risk after unusual DNA screening
This study follows pregnant people who had unusual noninvasive prenatal blood test results, to better understand the natural course and possible causes, including concerns about maternal cancer. You may join during pregnancy or up to 2 years after delivery, and you would share medical information and undergo follow-up visits.
