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 - NCT05027321Recruiting
Self-hypnosis to ease stress during breast biopsy
This study tests whether guided self-hypnosis—either by using a “mental anchor” or by a more conversational style—can reduce stress or discomfort during a breast macrobiopsy. It may help patients feel calmer during the procedure.
MarseilleAges 18 years+ - NCT04838522Recruiting
Prucalopride for constipation in breastfeeding women
This study looks at whether prucalopride (Motegrity/Resotran) can help constipation symptoms in women who are breastfeeding. It also monitors the breastfeeding infant during the study while you follow sample-collection and interview requirements.
La Jolla, CaliforniaAges 18 years+ - NCT04829877Recruiting
Study stress changes in women trying to get pregnant
This study follows how emotional distress changes over time in women who are starting infertility treatment and trying to conceive. It may help researchers understand what support might be most helpful during the start of fertility care.
TaipeiAges 20–60 - NCT04705467Recruiting
3D scanning of needles during gynecologic radiation treatment
This study uses 3D imaging to help guide needle-based radiation treatment for certain gynecologic cancers. If you are already scheduled to receive this type of brachytherapy, the trial may help make the treatment planning more accurate.
London, OntarioAges 18 years+ - NCT04730609RecruitingPhase 4
Dexmedetomidine to reduce shaking during scheduled C-section
This trial tests whether dexmedetomidine, a calming medicine, can reduce unwanted shaking (shivering) during a planned C-section done with spinal anesthesia. It may help make the surgery and recovery more comfortable.
Rochester, MinnesotaAges 18 years+ - NCT05000645Recruiting
Grocery delivery to help young pregnant women gain healthy weight
This study tests whether getting grocery delivery (with a focus on healthier foods) can help young women who are pregnant gain a healthy amount of weight. It’s aimed at low-income participants early in pregnancy who currently drink sugary beverages.
Ann Arbor, MichiganAges 14–26 - NCT05608421Recruiting
