This study looks at how satisfied women are with a special ultrasound test (HyFoSy) that uses foam to check the fallopian tubes and uterus as part of a fertility workup. It aims to learn if this method is comfortable and helpful for patients.
NancyAges 18 years+ - NCT06165367Recruiting
Does hyaluronan in the medium improve embryo transfer success?
This trial tests if adding hyaluronan to the liquid used during embryo transfer helps increase the chance of a successful pregnancy. It is for women who have at least one genetically normal embryo (tested with PGT-A) that was frozen on day 5 and are using hormone replacement therapy to prepare the uterus.
Abu Dhabi, Abu Dhabi EmirateAges 18–46 - NCT07020546Recruiting
Ovarian PRP Injections for Better Embryo Quality
This trial tests whether injecting platelet-rich plasma (PRP) into your ovaries can improve the quality of your embryos. You will go through two IVF cycles, and the treatment aims to help women with low embryo quality get better results.
New York, New YorkAges 18–47 - NCT07325994Recruiting
Pain control during hysteroscopy for women with infertility
This trial tests if using calming words (verbal analgesia) during a hysteroscopy can reduce pain compared to standard care. It is for women with primary infertility who need this procedure to check the uterus.
GizaAges 18–40 - NCT07185230Recruiting
Trial of atosiban for women with past implantation failure and abnormal uterine contractions
This trial tests if atosiban, a medicine that relaxes the uterus, can help women who have had multiple failed embryo transfers. It's for women whose uterus has abnormal contractions, which might prevent embryos from implanting.
Xi'an, ShaanxiAges 20–40 - NCT07675213Recruiting
Uterine muscle movements and pregnancy after frozen embryo transfer
This trial explores how natural uterine contractions affect pregnancy success in women using hormone therapy for frozen embryo transfer. It may help doctors understand if uterine activity influences implantation.
Ho Chi Minh CityAges 18–42 - NCT07499817RecruitingPhase 3
Effect of pentoxifylline on womb lining and frozen embryo transfer
This trial tests if a medication called pentoxifylline can help thicken the womb lining and improve success rates for frozen embryo transfers. It may be an option for people with a thin womb lining before their procedure.
Banī Suwayf, Beni Suweif GovernorateAges 18–43 - NCT00353210Recruiting
Use embryos from IVF for stem cell research
This study creates human stem cell lines from embryos left over after IVF. It may help researchers learn about stem cells, but you must agree to give consent and not use these specific embryos for building your family.
JerusalemAges 18 years+ - NCT00353197Recruiting
Donating long-stored IVF embryos for stem cell research
This study creates new lab cell lines from donated human embryos to support future clinical research. It may help researchers develop better treatments by starting from donated embryos that are carefully screened and consented.
JerusalemAges 18 years+ - NCT06701071RecruitingPhase 4
Comparing short vs long Clomid for IVF stimulation
This study tests whether a shorter or longer course of Clomid (a fertility medicine) works better for women who are expected to have a low response to ovarian stimulation. It may help those with a lower egg reserve still produce enough eggs for IVF.
Pasadena, CaliforniaAges 18–44 - NCT01500447Recruiting
Study of inherited causes of low puberty hormones
This study looks at families to understand inherited (genetic or family-related) reasons some people have delayed puberty or develop puberty abnormally. It may help doctors better figure out the cause of low sex hormone levels and related hormone problems.
Bethesda, MarylandAges 1 month–120 years - NCT06686537RecruitingPhase 2
Study on metabolism and hormones in women
This study looks at how metabolism and hormones are connected in women. It tests a treatment to see if it can improve metabolic health related to the menstrual cycle.
Aurora, ColoradoAges 18–38 - NCT03011684RecruitingPhase 3
Preserve eggs using tamoxifen and letrozole during new breast cancer treatment
This study tests whether taking tamoxifen and letrozole (with fertility injections) can help people with newly diagnosed, estrogen-sensitive breast cancer preserve eggs before cancer treatment starts. It may help protect future fertility by collecting eggs early, before chemotherapy or other treatments begin.
San Francisco, CaliforniaAges 18–50 - NCT03252795Recruiting
Uterus transplant for women with uterine absence
This trial tests whether receiving a uterus transplant can allow someone with uterine absence to carry a pregnancy. It also looks at whether the procedure is safe for the patient and supports a future baby using frozen embryos.
GhentAges 18–38 - NCT04166825Recruiting
Study how egg-stimulation blood clots form in infertility
This study looks at how your blood clots (and clotting proteins) behave around ovarian stimulation for infertility care. It may help researchers understand clot-related risks and improve how treatment is monitored.
Krakow, MałopolskaAges 18–40 - NCT04167748Recruiting
Genetic testing for embryos in IVF for women 35–40
This study looks at using embryo genetic testing before pregnancy in IVF for women aged 35 to 40. It may help by identifying which embryos are more likely to lead to a healthy pregnancy, though you would still be screened to confirm you fit the criteria.
Margate, FloridaAges 35–40 - NCT04196595Recruiting
Apple study for women’s health using an iPhone app
This study looks at women’s health by collecting information through an Apple Research app on your iPhone. You may help improve how health data is gathered, while also checking in with the study team by agreeing to participate.
Boston, MassachusettsAges 18 years+ - NCT04356664RecruitingPhase 2/Phase 3
GnRH shot before frozen embryo transfer for endometriosis
This trial studies whether giving a GnRH “downshifting” shot before transferring a frozen embryo can improve pregnancy outcomes for people with endometriosis or adenomyosis. It may help by changing hormone activity before the transfer.
SuresnesAges 18–36 - NCT04390308Recruiting
Testing gentle stimulation of ovaries before fertility treatment
This trial studies whether a “mechanical stimulation” procedure can help small egg-making structures in the ovary start to work again in people with primary ovarian insufficiency. If the procedure shows signs of response, you may then move on to further fertility treatment, including IVF.
Abu Dhabi, Abu Dhabi EmirateAges 18–40 - NCT04452305Recruiting
Frozen testicle tissue transplant to restore fertility
This study tests using previously frozen (cryopreserved) testicle cells or tissue to regrow testicular tissue. If you’ve had cancer treatment that can harm fertility, this may help restore natural fertility potential using your own tissue.
Pittsburgh, PennsylvaniaAges Any age - NCT04477863Recruiting
Follow-up study for people who had genetic testing in embryos
This trial follows up with people who chose to participate in research when getting preimplantation genetic testing (testing genes in embryos). It may help researchers understand outcomes and improve future genetic testing and counseling.
North Brunswick, New JerseyAges Any age - NCT04528498Recruiting
Embryo health study for IVF using PGT-A testing
This study looks at embryo health using a DNA test called PGT-A for couples having IVF. It may help researchers better understand what the test can and cannot tell about which embryos are healthiest.
North Brunswick, New JerseyAges 18 years+ - NCT04866329Recruiting
Study of stress and environmental exposures in IVF fertility
