Bisceglie, BTAges 20–42 - NCT07108621RecruitingPhase 3
HCG priming before IVF for low egg reserve
This trial tests whether giving a hormone called hCG before starting IVF can improve outcomes for women with low egg reserve (low AMH). It is designed for women under 40 who are early in their IVF journey.
CopenhagenAges 18–40 - NCT07087171Recruiting
AI tool for patient engagement in fertility treatment
This trial tests a new AI tool designed to help patients actively participate in their own fertility care. It may benefit people starting or considering medically assisted reproduction treatments like IVF or artificial insemination.
LisbonAges 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 - NCT05421364Recruiting
Boosting your own immune cells to improve the uterine lining
This study gives a small amount of your own immune cells into the uterus to change the immune environment in the uterine lining. It aims to improve how the uterine lining supports implantation, especially for people trying to conceive with embryo transfer of normal (euploid) embryos.
Sofia, SofiaAges 20–50 - NCT05775198Recruiting
IVF trial using your own immune cells to support embryo transfer
This trial studies whether placing your own immune cells (PBMCs) that have been adjusted with a medicine called IFN-<i>t</i> before embryo transfer can improve IVF success. It may help support the uterine environment around the time of implantation.
Sofia, SofiaAges 18–50 - NCT07066267Recruiting
Mitochondria from fat cells to boost IVF eggs
This study tests if giving your eggs a boost from your own fat-cell mitochondria can improve chances of a healthy pregnancy for people who have had multiple failed IVF cycles. You'll donate a small amount of fat through liposuction, and the mitochondria from those cells will be added to your eggs before fertilization.
ColomboAges 29–39 - 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 - NCT07074015Recruiting
AI tool to find sperm in surgery samples for male infertility
This study tests an artificial intelligence tool that helps doctors find very rare sperm in tissue removed during sperm retrieval surgery. If you have non-obstructive azoospermia (no sperm in your semen) and are having micro-TESE surgery, the AI might help find sperm that standard methods miss.
Boston, MassachusettsAges 18 years+ - 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 - NCT07039097Recruiting
Surgery for uterine septum to improve natural pregnancy
This trial tests if removing a uterine septum (a wall-like tissue inside the womb) through a minimally invasive procedure helps women who have not had repeated miscarriages get pregnant naturally. You would be randomly assigned to have the surgery or not, and your pregnancy outcomes would be tracked.
Changsha, HunanAges 20–40 - 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 - NCT07004192RecruitingPhase 4
hCG use in frozen embryo transfer
This study tests whether giving hCG before transferring a thawed embryo can improve success. It is for women who have at least one frozen embryo of good quality and are planning a frozen embryo transfer.
Las Vegas, NevadaAges 18 years+ - NCT06984081Recruiting
Egg maturation study for fertility preservation
This study tests a method to help eggs mature in a lab for people who want to preserve their fertility, such as before cancer treatment. It uses eggs collected during standard procedures.
Hong KongAges birth–50 years - NCT06940973Recruiting
Study of abnormally fertilized embryos
This trial studies embryos that formed from eggs or sperm with an unusual fertilization pattern. It aims to learn more about these embryos to possibly improve future fertility treatments.
Valencia, ValenciaAges 18–49 - NCT06887881Recruiting
Comparing two embryo-testing methods for women with PCOS
This trial compares a new way of testing embryos (PIMS) with the standard method (PGT-A) for women with polycystic ovary syndrome (PCOS) who are doing IVF. The goal is to see which method helps more women have a successful pregnancy.
Zhongshan, GuangdongAges 20–40 - NCT06826365Recruiting
Immune cells in the uterus and infertility
This study looks at immune cells inside the uterus to understand why some women have infertility or repeated miscarriages. You may join if you have had at least two miscarriages or certain benign gynecological conditions.
KrakowAges 18–45 - NCT06804538Recruiting
Comparing insemination timing 42 vs 36 hours after hCG injection
This trial tests whether waiting 42 hours after a hormone injection (hCG) before performing intrauterine insemination (IUI) leads to better pregnancy results than the standard 36-hour wait. It is for women or couples who are doing their first or second IUI and whose fallopian tubes are open.
BordeauxAges 18–43 - NCT05750849Recruiting
Checks progesterone levels to predict pregnancy in fertility treatment
This study looks at whether a blood progesterone level around the time of a pregnancy test during fertility treatment helps predict which patients will have an ongoing pregnancy. It may help doctors better understand who is most likely to continue developing a pregnancy during artificial cycles.
Valencia, ValenciaAges 18–50 - NCT06771401Recruiting
Cervical mucus biomarkers for fertility
This study is looking for two groups: healthy women with proven fertility and women with unexplained infertility (no known reason for not getting pregnant). Researchers want to study cervical mucus to find biomarkers that might help understand fertility better.
Rome, RomaAges 18–45 - NCT06587360Recruiting
FertiShare study: sharing fertility information
This study looks at a new way for fertility clinics to share information with patients. It aims to see if this helps patients and clinics work better together.
