Recruiting studies
- NCT06261658Recruiting
Using your own blood to improve ovary tissue transplant
This study tests whether using a special mix made from your own blood (called platelet-rich plasma) can improve the success of putting frozen ovarian tissue back into your body. This might help restore your fertility and hormone function after cancer treatment or other conditions.
Bologna, BOAges Any age - NCT07546123Recruiting
Freezing Ovarian Tissue and Eggs for Cancer Patients
This trial compares two methods of preserving a woman's fertility before cancer treatment: freezing eggs alone versus freezing both eggs and ovarian tissue. The goal is to help women who may lose fertility due to chemotherapy or radiation keep their options open for having biological children in the future.
Bologna, BolognaAges 18–46 - 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 - NCT07542626Recruiting
Restoring Fertility by Transplanting Frozen Testicular Tissue
This trial tests whether transplanting frozen testicular tissue that was saved before cancer treatment can help men who cannot produce sperm have biological children. The tissue is thawed and put back into the testicles to restore natural sperm production.
BrusselsAges 18–40 - NCT06835088Recruiting
Reimplantation of frozen ovarian tissue
This study looks at how often women who had ovarian tissue frozen come back to have it reimplanted, and whether the tissue helps restore ovarian function after treatment.
BolognaAges 13–55 - NCT07321028Enrolling by invitationEarly Phase 1
Study of freezing methods on human cell samples
This study tests different freezing methods on human cell samples to see which work best. It does not involve human volunteers, only donated cells that have been de-identified.
New York, New YorkAges Any age - NCT06853418Recruiting
Comparing a new vitrification system to standard method for IVF
This study tests a new semi-automated system for freezing eggs (vitrification) to see if it works as well as the standard manual method. It involves egg donors and recipients undergoing IVF with donor eggs.
Novato, CaliforniaAges 18–45 - NCT06747715Recruiting
Treating facial injuries with fresh and frozen fat grafting
This trial uses your own fat to fill in facial depressions or defects from an injury or surgery. First, fresh fat is used for grafting, and extra fat is frozen to use later if needed.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06518746Recruiting
Freezing gonadal tissue to preserve fertility
This study looks at the best way to preserve your fertility by freezing gonadal tissue (ovarian or testicular tissue) before it is removed. It may help if you have a disorder of sex development and are at risk of losing your ability to have children.
Aurora, ColoradoAges Up to 30 years - NCT06505057Recruiting
Freezing and re-implanting ovarian tissue for young cancer patients
This study tests a method to preserve fertility by freezing ovarian tissue before cancer treatment and later re-implanting it. It may help young women and girls who face infertility from their cancer therapy.
Hong KongAges 12–18 - NCT06387498Recruiting
Testicular Tissue Freezing for Fertility Preservation
This trial stores testicular tissue before certain medical treatments that could cause permanent infertility. It may help preserve your chance of having biological children in the future.
Aurora, ColoradoAges Any age - NCT02872532Recruiting
Freezing testicle tissue in children before cancer treatment
This trial studies how doctors collect and freeze a small piece of testicle tissue from boys to protect future fertility before treatments like chemotherapy or radiation. It may help families preserve options for having children later if testicular function is permanently affected.
Rochester, MinnesotaAges birth–17 years - NCT01351545Recruiting
Cryopreserved cord blood access program for transplant patients
This trial studies an organized way to obtain and distribute unlicensed (not FDA-approved for general use) stored cord blood units that have been frozen and kept. It may help people who need a cord blood transplant but don’t fit the “licensed cord blood only” options.
Birmingham, AlabamaAges Any age - 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 - NCT06626282Recruiting
Fertility after childhood cancer in women
This study looks at how well the ovaries work in women who had childhood cancer. Researchers want to know if cancer treatments affected fertility.
Liège, WalloniaAges 18–50 - NCT07629245RecruitingPhase 1/Phase 2
Cell therapy for Crohn's disease fistulas after prior treatment
This trial tests whether injecting your own fat-derived cells combined with a skin graft can heal anal fistulas (abnormal passages near the anus) that didn't respond to or came back after a previous cell therapy study. You must have already participated in the ADICROHN-2 study.
MarseilleAges 18 years+ - NCT07546942Enrolling by invitationPhase 1/Phase 2
Autism Treatment Using Stem Cells, Gut Microbiome, and Diet
This study tests whether a combination of stem cell therapy, gut microbiome restoration (using specially prepared stool), and dietary changes can improve autism symptoms, communication, social behavior, and digestive issues. Researchers believe gut health and immune system problems may contribute to autism, and this trial explores whether treating these areas helps.
Hamilton, MontanaAges 10–90 - NCT07484815Recruiting
Virtual reality for pain during egg freezing
This study tests whether using a virtual reality (VR) headset during egg freezing can help reduce pain. If you are having your eggs retrieved to preserve your fertility, you may be able to take part and wear a VR device to see if it makes the procedure more comfortable.
JerusalemAges 18–45 - NCT06829654Recruiting
Reimplanting frozen ovarian tissue in sarcoma and blood cancer survivors
This study looks at transplanting ovarian tissue that was frozen before cancer treatment to help restore fertility and hormone function in people who survived sarcomas or blood cancers. It aims to see if this procedure is safe and effective.
BolognaAges 18–38 - NCT07270679Recruiting
Genetic markers for ovarian damage after chemo
This study is looking for genetic markers that may help predict how chemotherapy affects the ovaries. It's for women who had breast cancer or lymphoma, froze their ovarian tissue before treatment, and finished that treatment at least 6 months ago.
Bologna, BolognaAges 18–38 - NCT07240259Enrolling by invitation
Using a donated aortic patch to rebuild a child's windpipe
This trial tests a new way to repair a child's windpipe using a piece of donated aorta (a blood vessel) as a patch. It's for children who have severe breathing problems from a narrowed or damaged windpipe and cannot have standard surgery.
TaipeiAges birth–18 years - NCT07219654RecruitingPhase 2
Study of TPX-115 for partial rotator cuff tear
This study tests an experimental treatment called TPX-115 for people with a partial-thickness rotator cuff tear. It aims to see if the treatment can reduce pain and improve function compared to standard care.
La Mesa, CaliforniaAges 18 years+ - NCT07140549Enrolling by invitation
Fertility preservation after childhood cancer treatment
This study surveys adults who had fertility preservation counseling and testicular tissue freezing before gonadotoxic treatment as children. It aims to learn about their experiences and long-term outcomes.

Common questions
- Are there clinical trials for cryopreservation?
- Yes. Clin2 currently lists 42 recruiting cryopreservation 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 cryopreservation 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 cryopreservation 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.
