Recruiting studies
- NCT03463252RecruitingPhase 2/Phase 3
Hormone IUD to preserve fertility in early uterine cancer
This study looks at whether a hormone-releasing IUD (LNG-IUS) can treat early-stage endometrial cancer or very early abnormal cell growth while helping you keep the option for future pregnancy. It aims to see how well the treatment works and how it affects fertility-related outcomes.
Chengdu, SichuanAges Up to 40 years - NCT04362046Recruiting
Fertility-friendly treatment for early uterine cancer or precancer
This trial studies whether removing an early, hormone-responsive uterine growth using a procedure through the cervix can keep fertility possible. It is for people under 40 with a specific low-risk uterine biopsy and MRI findings who have already tried hormone treatment.
Vancouver, British ColumbiaAges 19–39 - NCT04682470Recruiting
Research study following young adults with cancer
This is an observational study that follows young adults with a confirmed cancer diagnosis to learn more about their experience and care. It does not test a new drug, but your information may help improve future cancer treatment and support.
Amsterdam, North HollandAges 18–39 - NCT05328258RecruitingPhase 3
Triptorelin to help protect fertility during cancer chemotherapy
This Phase 3 study tests whether a hormone medicine called triptorelin (a GnRH “fertility-protecting” medicine) can better protect ovarian function while you receive chemotherapy. The goal is to help preserve fertility and reduce the risk of early ovarian failure from cancer treatment.
GothenburgAges 14–42 - NCT06134609Recruiting
Does sex affect frozen embryo transfer success?
This study looks at whether having sex (vaginal intercourse) around the time of a frozen embryo transfer affects the chance of pregnancy. If you are a woman under 42 with a good quality embryo and can have vaginal intercourse, you may be able to join.
Ramat GanAges 18–41 - 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 - NCT04583150Recruiting
Study of fertility and ovarian reserve after weight-loss surgery
This study looks at how ovarian reserve (a fertility-related marker) changes in women after bariatric (weight-loss) surgery versus women with obesity who are not planning surgery. It may help doctors better understand fertility timing and risks around weight-loss treatment.
AngersAges 18–37 - NCT06294314Recruiting
ACL surgery with bone marrow and internal brace for return to sports
This trial studies a new way to reconstruct a torn ACL using your own bone marrow cells and a special internal brace to help you return to sports. It's for young athletes who haven't had ACL surgery before.
Huntington, West VirginiaAges 14–26 - NCT05882188Recruiting
Test which tubal scan is more cost-effective
This study compares two ways to check whether the fallopian tubes are open during a fertility work-up. It looks at which test is more cost-effective, and it may help guide which option you use.
AmsterdamAges 18–42 - NCT05725512RecruitingPhase 4
Prednisolone to prevent unexplained recurrent miscarriages
This trial tests whether a medicine called prednisolone can help prevent further miscarriages in people who have had recurrent miscarriages with no known cause. If you qualify, you would take prednisolone early in pregnancy and the study team would watch whether more losses occur.
Leiden, South HollandAges 18–40 - NCT05740579Recruiting
Storing eggs in teens with Turner syndrome variants
This study looks at freezing and storing eggs (cryopreservation) in children and teens with Turner syndrome or related genetic variants. It may help preserve the chance of having biological children later, if you are able to undergo the study procedures safely.
AarhusAges 2–17 - NCT06064669Recruiting
Metformin for healthy live birth in women with prediabetes
This study tests if metformin, a drug that helps control blood sugar, can improve the chance of a healthy live birth in women with prediabetes who are doing in vitro fertilization (IVF). It aims to see if treating prediabetes before and during early pregnancy leads to better outcomes.
Jinan, ShandongAges 20–40 - NCT07814235Recruiting
Freezing sperm as a way to protect quality as men age
This study is looking at whether freezing sperm can protect the quality of sperm as men age. If you join, you'll provide samples for research, and the findings could help men plan for future fertility.
Murcia, MurciaAges 18–65 - NCT05328999Recruiting
Study links fertility, pregnancy loss, and gut microbes
This trial studies how gut bacteria (your “microbiome”) may relate to infertility, recurrent pregnancy loss, and time to pregnancy. It may help researchers understand what could be changed to improve fertility outcomes.
Graz, StyriaAges 18–50 - NCT04866329Recruiting
Study of stress and environmental exposures in IVF fertility
This study looks at how environmental exposures and stress-related “oxidant” changes may affect fertility outcomes in IVF for women. You may be invited if you are in your first IVF egg retrieval cycle and meet the study’s specific IVF setup rules.
ToursAges 18–43 - 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 - NCT06530992Recruiting
Tucking and semen quality in adult trans women
This study looks at whether tucking affects semen quality in adult transgender women who are about to start or are on hormone therapy. The results could help patients understand how tucking might impact their fertility options.
InnsbruckAges 18–50 - NCT07789730Enrolling by invitation
In vitro maturation for women undergoing fertility treatment
This study tests a new way of growing eggs in the lab called in vitro maturation (IVM) for women undergoing fertility treatment. It may help women who have concerns about hormone injections, as IVM uses less medication.
Houston, TexasAges 18–37 - NCT07765368Enrolling by invitation
Body fat versus BMI for IVF success
This study looks at whether body fat percentage or BMI is a better predictor of IVF outcomes. It may help personalize fertility treatment plans.
Halifax, Nova ScotiaAges 21–44 - NCT02081924Recruiting
Testing kisspeptin hormone delivery and blood hormone changes
This study gives the hormone kisspeptin over time and measures how your body’s reproductive hormones respond. It may help researchers understand how reproductive hormone signals work, which could guide future treatments.
LondonAges 18–60 - NCT06602687Recruiting
Does PICSI improve embryo health in older couples?
This study looks at whether a specific sperm selection method (PICSI) helps increase the number of chromosomally normal embryos in couples using ICSI and PGT-A. It may be especially relevant if you are an older couple or have concerns about sperm quality.
Dublin, DublinAges 35 years+ - NCT07724405RecruitingPhase 2
G-CSF for Unexplained Recurrent Miscarriage During IVF
This study tests whether G-CSF (a medicine that helps the immune system) given during IVF can reduce miscarriages in women who have had repeated pregnancy losses with no clear reason.

Toronto, OntarioAges 18–45 - NCT07684339Recruiting
Sperm protein test and fertility treatment
This study looks at a protein in sperm called phospholipase C zeta, which helps eggs develop after fertilization. It aims to see if measuring this protein can predict how well a couple will do with fertility treatments like IVF or ICSI.
