Recruiting studies
- NCT06691750Recruiting
Barbed Suture Study for Cesarean Wound Healing
This trial tests if a special type of stitch (barbed suture) used to repair the uterus during cesarean section can reduce the chance of developing a small pocket or gap in the uterine scar, called isthmocele. If you are having a planned or emergency c-section at Hospital Clinic of Barcelona, you may be able to join.
BarcelonaAges 18 years+ - 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.
Abu DhabiAges Any age - NCT06710769Recruiting
Ovarian tissue freezing before cancer treatment
This study helps people who are about to start cancer treatment (or have certain health conditions) preserve their ability to have children later. It removes and freezes a small piece of ovarian tissue before treatments that could damage the ovaries.
Phoenix, ArizonaAges 1–25 - NCT06742437Recruiting
Study of a new sperm preparation method
This study tests a new method for preparing sperm to help with fertility treatments. It is for men who can provide a semen sample and have no active infections or history of certain viruses.
Barcelona, BarcelonaAges 18–60 - 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 - 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 - NCT06841861RecruitingPhase 1/Phase 2
Testicular organoid study for male fertility
This trial uses tiny lab-grown testicles to study sperm production. It may help men with infertility learn more about why they can't make sperm.
San Francisco, CaliforniaAges 18–60 - NCT06869863RecruitingPhase 1/Phase 2
Study of MediReg® for severe male infertility
This study tests an experimental medicine called MediReg® for men with severe infertility who have not been able to conceive. It aims to see if the drug is safe and can improve sperm quality, possibly offering a new option for men who have not had success with other treatments.
Moscow, MoscowAges 21–60 - NCT06896747RecruitingPhase 1/Phase 2
Stem cell therapy for thin uterine lining
This trial tests a new treatment using stem cell particles (exosomes) to help rebuild the lining of the womb in women whose lining is too thin after surgery for scar tissue. It may improve chances of success with IVF.
Xi'an, ShaanxiAges 20–40 - NCT06950203Recruiting
Fish oil supplement for sperm quality
This study tests whether a special fish oil supplement (EPAX EVOLVE 05) can improve sperm movement in men with low sperm motility. It may help if you have been told your sperm are not moving well and you are willing to take a sperm test.
OsloAges 18–55 - 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 - 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 - 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 - 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+ - 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 - NCT07128394Recruiting
Extra LH hormone for better embryos in IVF with low LH
This trial tests whether giving extra luteinizing hormone (LH) can improve embryo quality in women with very low LH levels during IVF. It may help you if you have low LH and are using a specific type of fertility medication.
Nanjing, JiangsuAges 20–37 - NCT07159880Recruiting
Letrozole for ovulation induction in PCOS
This trial tests a longer course of letrozole to help women with PCOS ovulate and get pregnant. The goal is to see if extended therapy works better than the standard treatment.
São Paulo, São PauloAges 18–40 - NCT07175571Recruiting
Comparing insemination methods with frozen donor sperm in IVF
This study compares different insemination methods when using frozen donor sperm during IVF. It aims to find the best technique to help more eggs get fertilized.
Rockville, MarylandAges Any age - NCT07197983Recruiting
Automated egg freezing trial
This trial tests a new automated method for freezing eggs and embryos. If you have a healthy ovarian reserve and normal body weight, you may be able to join.
ManchesterAges 18–38 - NCT07230600RecruitingPhase 1
Stem cell therapy for thin uterine lining or scarring
This trial tests a new treatment for people with a thin uterine lining or uterine scarring that hasn't responded to other stem cell therapy. It might help improve the lining so pregnancy is possible.
Nanjing, JiangsuAges 22–45 - NCT07231510Recruiting
Chlordecone exposure and female fertility study
This study looks at how exposure to chlordecone, a chemical found in some Caribbean soils, might affect a woman's ability to get pregnant. You may be asked to share your medical history and provide samples to help us understand this link.
Pointe-à-PitreAges 18–39 - NCT07240363Recruiting
Surgery or fertility treatment first for advanced endometriosis
This trial compares starting with surgery versus starting with fertility treatment (like IVF) for people with advanced endometriosis who may want to have children. The goal is to see which approach first leads to better outcomes.
Stockholm, Stockholm CountyAges 18–38 - NCT07242534RecruitingPhase 4
Semaglutide for better embryos in IVF for women with overweight or obesity
This trial tests whether semaglutide, a medication used for weight management, can improve the quality of embryos in women who are overweight or have obesity and are doing IVF. It aims to see if taking semaglutide before the IVF process helps make healthier embryos that can be frozen for later use.
Sabadell, BarcelonaAges 18–38 - NCT07257250Recruiting
Levothyroxine for IVF in women with mild thyroid issues
This study tests whether taking levothyroxine (a thyroid hormone medication) before IVF or ICSI with frozen embryo transfer improves pregnancy rates in women with subclinical hypothyroidism (a mild thyroid condition). It aims to see if this treatment helps women like you have a better chance of getting pregnant.

- Yes. Clin2 currently lists 262 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.
