Tranexamic acid during vaginal hysterectomy to reduce bleeding
This trial studies whether giving tranexamic acid during a vaginal hysterectomy (uterus removal through the vagina) can reduce blood loss. It may help some people need less bleeding during surgery, if they are able to take the medicine safely.
Kfar Saba, IsraelAges 20–90 - NCT04829058Recruiting
Follow-up study for women who received mesh for prolapse surgery
This study is checking women’s outcomes after a specific prolapse surgery where a mesh material (GYNEMESH PS) was used. If you had this operation and can do follow-up visits, this study may help doctors better understand the mesh’s real-world safety and results.
North Wales, PennsylvaniaAges 21 years+ - NCT05035160Recruiting
Join a pregnancy tissue and sample study for research
This study collects and stores samples from pregnancy, birth, or after delivery to help researchers learn from perinatal health information. It may help future care by building a high-quality repository of biospecimens and related data.
Los Angeles, CaliforniaAges 1 minute+ - NCT04719000RecruitingPhase 4
Personalized LH addition during IVF to improve egg growth
This trial tests whether adding a personalized amount of “LH” during IVF hormone stimulation can help your ovaries respond better. It may be useful if you’ve had a weaker IVF response before and fit specific age and egg-quality markers.
BarcelonaAges 35–40 - NCT05142150Recruiting
Care and expectations study for advanced gynecologic cancer
This trial looks at what patients with advanced gynecologic cancer expect from care, and how well their care needs are being met. It uses questionnaires to learn what support is most helpful, especially near the end of life.
OsloAges 18 years+ - NCT05193968Recruiting
Study hot flashes and blood vessel function in women
This study looks at how hot flashes relate to how well your blood vessels work in the body. It may help researchers understand the body changes behind hot flashes, which could guide future treatments.
Rochester, MinnesotaAges 40–60 - NCT05058872RecruitingPhase 4
Study links birth-control hormones to brain reward responses
This Phase 4 study uses brain imaging and daily questions to understand how contraceptive hormones may affect reward and brain signals. You may be able to join if you meet the health, birth-control, and safety requirements for MRI.
Aurora, ColoradoAges 18 years+ - NCT04757922Enrolling by invitation
Tests whether removing fallopian tubes affects menopause timing
This trial studies whether an “opportunistic salpingectomy” (removing fallopian tubes) during sterilization changes when menopause happens. It compares people who have this procedure to those who get different sterilization (tubal ligation) or none.
EindhovenAges 30–45 - NCT04722900Recruiting
Study of children born to mothers with gestational diabetes
This study looks at children whose mothers did or did not have gestational diabetes during pregnancy. It will help researchers understand possible differences in children and how pregnancy diabetes may affect them.
TübingenAges 6–17 - NCT05233462Recruiting
Compare two spinal anesthesia bupivacaine dose methods for C-sections
This trial looks at whether adjusting the dose of bupivacaine by height works better than using a standard dose for spinal anesthesia during planned C-sections. It may help improve safety and comfort by aiming for the right level of numbing effect.
CaenAges 18–45 - NCT04721899Recruiting
Vitamin D study to improve uterine lining for pregnancy
This trial tests whether taking vitamin D can improve the uterine lining’s readiness for pregnancy in women who struggle to conceive. It compares different groups of infertile patients to see who may benefit and to monitor for safety.
Hong KongAges 18–40 - NCT05080569RecruitingPhase 4
Extra support after IUI for couples with unclear infertility
This study tests whether adding support in the period after ovulation (the “luteal phase”) helps people who are starting IUI (intrauterine insemination) because their infertility is unexplained. It’s designed to see if the added care improves chances when mild ovarian stimulation is used.
UtrechtAges 18 years+ - NCT05221021RecruitingPhase 4
Vaginal estrogen vs oral bladder medicine for overactive bladder
This study compares vaginal estradiol (a hormone placed in the vagina) versus an oral beta-3 medicine called mirabegron for overactive bladder symptoms. It looks to see which treatment works better and is safer for postmenopausal women.
Bethesda, MarylandAges 18 years+ - NCT04886791Recruiting
Compare two ways to remove the uterus through the vagina
This study compares a newer “vaginal NOTES” approach with the standard way of removing the uterus through the vagina. It may help find which method is safer or easier for people who need a hysterectomy for non-cancer (benign) reasons.
Eindhoven, North BrabantAges 18 years+ - NCT04760327RecruitingPhase 2
Electrotherapy for returning gynecologic cancers
This Phase 2 study tests electrotherapy (a way to help treatment reach tumor cells) for gynecologic cancers that have come back after standard treatments were used up. You may be considered if your overall health allows anesthesia and if certain cancer spread and medical safety issues do not apply.
LjubljanaAges 18–105 - NCT05109208Recruiting
Ultrasound check for erection recovery after prostate surgery
This study looks at whether ultrasound imaging can help understand and improve erectile function after prostate removal surgery that aims to protect the nerves. If you’re interested in keeping or improving erections, your ultrasound results may be used to guide follow-up care.
Rochester, MinnesotaAges 40 years+ - NCT05007834Recruiting
Study of sleep–hormone timing after chemotherapy-related missed periods
This study looks at how the body’s daily timing (circadian rhythms) may affect ovarian function and fertility after chemotherapy. It includes women who stopped having periods after chemotherapy and may help explain what to expect for post-cancer fertility.
LilleAges 25–35 - NCT05257746Recruiting
Testing bladder and rectal function after rectal surgery
This study follows people after rectal surgery to check how well the rectum and urinary (bladder) functions work over time. It may help doctors better understand recovery and what can improve quality of life after surgery.
Dresden, SaxonyAges 18 years+ - NCT06513624RecruitingPhase 1
ETC-159 plus pembrolizumab for advanced ovarian cancer
This trial tests a new combination of two drugs—ETC-159 (a pill that targets a specific growth pathway) and pembrolizumab (an immunotherapy)—for people with advanced ovarian cancer that has stopped responding to platinum chemotherapy. The goal is to see if this combination can help shrink tumors or slow their growth.
Singapore, SingaporeAges 21–99 - NCT04889469Recruiting
Breast size reduction for people with heavy, painful breasts
This study looks at who might qualify for breast reduction surgery in Sweden’s public healthcare system. It aims to match people with very large breasts and related symptoms to treatment criteria, and compare groups who do and do not meet those standards.
GothenburgAges 18–75 - NCT05205317Recruiting
VR alone or VR plus metformin for C-section scar healing
This study compares two treatments to help improve a C-section scar defect (an issue seen on the uterus scar). Some participants may receive virtual reality (VR) therapy plus metformin, while others receive VR alone, and the researchers will look at symptoms and scar healing.
Shanghai, Shanghai MunicipalityAges 18–40 - NCT05538091RecruitingPhase 2
Testing vismodegib plus atezolizumab for platinum-resistant ovarian cancer
This Phase 2 trial tests whether combining vismodegib with atezolizumab can slow or shrink platinum-resistant ovarian, fallopian tube, or primary peritoneal cancer. It targets cancers that grow again within 6 months after platinum chemotherapy.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05046080Recruiting
Testing after diagnosis of clear cell cervical cancer
This study is for people who have been diagnosed with clear cell cancer of the cervix. It looks at cancer tissue and related lab tests to better understand the disease and possibly guide care decisions.
Houston, TexasAges Any age - NCT05251324Recruiting
Study effects of hot flushes on heart and blood pressure
This study looks at how hot flushes (also called hot flashes) may affect heart function and blood pressure in postmenopausal people. You may be able to take part if you are not currently using hormone therapy or can stop it for the study.
Minneapolis, MinnesotaAges 40–70
