Recruiting studies
- NCT05599438Recruiting
Fitness and drug use study in recreational athletes
This study follows recreational athletes to understand how past and current anabolic-androgenic steroid (AAS) use relates to fitness changes over time. If you have used these substances in the past (and stopped more than 3 months ago), or you have never used them, you may be able to join.
CopenhagenAges 18 years+ - NCT07855783Recruiting
Predicting pregnancy success after fertility treatments
This study uses past patient information and early pregnancy blood test results to create a computer model that can forecast whether a fertility treatment will lead to a live birth. If you have undergone fertility treatment and had a positive early pregnancy test, your data may help improve predictions for future patients.

Uterine fibroids and pregnancy study
This study looks at how uterine fibroids affect pregnancy in women. It may help doctors understand the link between fibroids and fertility.
Wuhan, HubeiAges 20–50 - NCT04472156Recruiting
Testing one embryo transfer after mosaic PGT results
This study follows people who have infertility and, after IVF testing (PGT), have a “mosaic” embryo result. It looks at transferring one embryo to see how this approach works when mosaic changes are present.
Lone Tree, ColoradoAges 18–45 - NCT06123975Recruiting
Adenomyosis and infertility: immune factors trial
This study tests if treating immune system factors can help women with adenomyosis who are having trouble getting pregnant. It aims to see if addressing these immune aspects improves pregnancy chances.
BeijingAges 18–40 - 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 - NCT06384794Recruiting
ZyMōt sperm selection and its effect on embryo chromosome health
This study tests whether a sperm selection method called ZyMōt can help improve the chromosome health (ploidy) of embryos in couples who are already doing ICSI and PGT-A. It focuses on women over 37 and uses a fresh semen sample.
MadridAges 18 years+ - NCT07844083Recruiting
Artificial intelligence for choosing embryos in first ivf cycle
This trial uses artificial intelligence to help doctors pick the best embryo to transfer on day 5 of development. It aims to improve the chances of a successful pregnancy in your first IVF or ICSI cycle.
Clermont-FerrandAges 18–37 - 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+ - 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 - NCT07810920Recruiting
Ultrasound with AI to improve diagnosis
This study uses artificial intelligence to make ultrasound scans more accurate for diagnosing conditions like endometriosis and other uterine problems. If you're planning fertility treatment or surgery, this could help doctors find issues earlier.
Budapest, BudapestAges 18–45 - NCT07801105Recruiting
Hormone-free egg collection for storing embryos
This study tests a new way to collect eggs without using fertility hormones, then fertilize them and freeze the embryos for later transfer. It may help women who want to avoid hormone injections, but it requires several monitoring visits and specific health criteria.
Bedford, TexasAges 18–35 - NCT07808229Recruiting
Fallopian tube function assessment and personalized treatment
This study looks at how well the fallopian tubes work and uses that information to choose the best treatment for women struggling to get pregnant. It may help find the right approach for you based on your specific condition.
Beijing, Beijing MunicipalityAges 20–40 - 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 - NCT06518928Recruiting
AI sperm selection for IVF with ICSI
This trial tests an artificial intelligence system that helps select the best sperm for use during IVF with ICSI. The goal is to see if this improves fertilization, embryo development, and reduces early pregnancy loss.
Las Vegas, NevadaAges Any age - 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 - 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 - NCT07783399Recruiting
Carnitine supplement for women having IVF
This study tests whether taking a carnitine supplement before and during IVF can improve egg quality. It may help women who are having trouble with egg development during fertility treatment.
Belgrade, Savski VenacAges 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 - 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 - NCT06051201Recruiting
ReceptIVFity test for IVF success prediction
This trial studies a vaginal swab test called ReceptIVFity that looks at the bacteria in your vagina to see if it can help predict how well IVF will work. You can join if you're about to start your first IVF cycle, are not on hormonal birth control or antibiotics, and your IVF is not for emergency reasons.
RotterdamAges 18–42 - 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+ - NCT07736859Enrolling by invitation
A study on foam ultrasound for fertility evaluation
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+ - NCT05960370Recruiting
Testing a tighter embryo placement technique in natural frozen transfers
This study looks at whether “endometrial compaction” (a technique used during frozen embryo transfer) improves pregnancy and baby outcomes. It focuses on people having a frozen transfer using embryos that test normal on genetic screening.

Common questions
- Are there clinical trials for infertility?
- Yes. Clin2 currently lists 251 recruiting infertility studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a infertility trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a infertility trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
