This study uses an artificial intelligence (computer) tool to look at results from IVF and related fertility treatments. It may help clinicians assess outcomes more accurately for people going through ovarian stimulation and embryo or egg freezing.
New York, New YorkAges 18–89 - NCT05538338Recruiting
Platelet-rich plasma to improve thin uterine lining
This trial studies whether platelet-rich plasma (PRP) can help grow a thin uterine lining enough to support a pregnancy. It is aimed at people who have had repeated unsuccessful frozen embryo transfers and had a lining of 6 mm or less.
Basking Ridge, New JerseyAges 18–45 - NCT02357654RecruitingPhase 4
Hormone treatment to support the uterine lining in IVF cycles
This trial tests whether a hormone called GnRH can help support the lining of the uterus after IVF, ICSI, or frozen embryo (FET) embryo transfer. It may be offered around the time of embryo transfer to improve the chances of a successful implantation.
Hasbrouck Heights, New JerseyAges 18–40 - NCT03717441Recruiting
Study DNA from leftover IVF lab samples
This study looks at DNA found in leftover IVF lab materials to see if it can provide useful information during embryo screening. You might benefit indirectly by helping researchers test a less wasteful way to learn about embryos during IVF with chromosomal screening.
Lone Tree, ColoradoAges 18–44 - NCT01870752Recruiting
Transplanting frozen ovarian tissue to help you try for pregnancy
This trial studies whether thawed, previously frozen ovarian tissue can be transplanted to help people with ovarian insufficiency become pregnant. It may help if you already have cryopreserved ovarian tissue stored and your care team feels you’re a good candidate for the procedure.
Philadelphia, PennsylvaniaAges 18–45 - NCT05775211Recruiting
PBMC immune therapy added during fertility treatment
This trial studies whether giving your own immune cells (PBMC) to the uterus, modified with interferon (IFN‑t), can improve how endometrial (uterine lining) cells behave during infertility treatment. It may help some people with primary infertility who are undergoing assisted reproduction.
Sofia, SofiaAges 18–50 - NCT06521372Recruiting
AI egg sorting for better IVF embryos
This study tests whether an AI tool that sorts fresh mature eggs by their images can help more become usable blastocysts (embryos that can be transferred) and lead to pregnancy during IVF. It is for people doing ICSI with fresh eggs and planning to transfer one blastocyst.
Las Vegas, NevadaAges Any age - NCT03507673Recruiting
Study of vaginal and uterine microbiome after frozen embryo transfer
This study looks at how bacteria in the vagina and lining of the uterus change during the “luteal phase” (the time after ovulation and before a pregnancy test) in people using frozen embryo transfers. It may help researchers understand what conditions support embryo implantation and pregnancy in assisted reproduction.
Saarbrücken, SaarlandAges 18–45 - NCT06358547Recruiting
Genetic testing of embryos for women aged 37-41
This trial tests whether checking embryos for extra or missing chromosomes (aneuploidy) before transfer improves IVF success for women aged 37-41. You may be eligible if you have a partner or are using donor sperm and have normal ovarian reserve.
København ØAges 18–41 - NCT07409493Recruiting
Comparing two IVF methods with time-lapse imaging
This study compares two types of ovarian stimulation protocols (PPOS and GnRH antagonist) for women undergoing IVF with a freeze-all embryo plan. It uses time-lapse imaging to see if one approach leads to better embryo development.
HanoiAges 20–45 - NCT06319573Recruiting
Personalized IVF counseling for better treatment decisions
This study tests whether a personalized report (Univfy® PreIVF Report) can help people understand their chances with IVF and make decisions about treatment. It is for women under 44 using their own eggs for IVF.
BarcelonaAges 18–43 - NCT07515118Recruiting
Using AI to improve egg-stimulation timing for IVF
This study tests artificial intelligence to optimize when doctors trigger egg release during IVF treatment. Better timing may improve egg quality and IVF success rates. You'll have all ultrasound monitoring at the study center.
Sabadell, BarcelonaAges 18–42 - NCT06581068Recruiting
Automated IVF lab study for better fertility outcomes
This study tests a new automated system for IVF lab procedures to see if it improves success rates. Patients with specific fertility needs may join if they meet health and age requirements.
Mexico City, Mexico CityAges 18–45 - NCT07685431Recruiting
Alpha-lipoic acid for IVF in women 35-45
This trial tests whether taking alpha-lipoic acid (an antioxidant supplement) before and during IVF can improve pregnancy success in women aged 35–45 using their own eggs. It aims to see if the supplement can help counter age-related declines in egg quality.
Kaohsiung CityAges 35–45 - NCT06144268Recruiting
Sperm selection for intrauterine insemination
This trial tests a device called ZyMōt Multi that selects the best sperm for intrauterine insemination (IUI). It may help couples trying to conceive by improving the chance of a live birth.
BrusselsAges 18–36 - NCT07036536Recruiting
Non-Euploid Embryo Transfer Registry
This registry is collecting information from people who plan to transfer an embryo that is not genetically normal (non-euploid) at a fertility clinic in The Prelude Network. It will help doctors learn more about outcomes with these embryos.
Houston, TexasAges Any age - NCT06005311Recruiting
Comparing sperm preparation methods in IVF
This trial compares two ways of preparing sperm for IVF: a new microfluidic chip method versus the standard density-gradient centrifugation. It aims to see which method leads to more successful fertilizations and pregnancies.
Hong Kong, Hong KongAges Up to 43 years - NCT07556601Recruiting
Fast Freezing of Embryos for Future Use
This study tests a new, quicker way to freeze embryos (blastocysts) that are ready for use in future pregnancy attempts. It may help preserve embryo quality and improve success rates for people using donor eggs.
