Recruiting studies
- NCT05309746Recruiting
Save ovarian tissue before cancer treatment
This trial studies freezing (cryopreserving) ovarian tissue before treatment that may permanently affect fertility and hormone production. You might consider it if you are planning surgery, chemotherapy, or radiation soon and want to preserve future options.
Chicago, IllinoisAges Up to 30 years - NCT05458440Recruiting
Study using immune cells from recovered COVID-19 donors
This study collects immune cells from people who recovered from COVID-19 and may use them to boost protection against SARS-CoV-2. It’s for hospitalized patients who already show a certain level of COVID-19 fighting immune response.
Vandœuvre-lès-Nancy, LorraineAges 18–70 - NCT05830929Recruiting
Freezing ovarian tissue and later putting it back
This study tests a way to protect future fertility in young people who need cancer treatment. It freezes ovarian tissue before treatment and, if appropriate, later returns it to the body to help restore hormone production and possible future pregnancy.
Hong KongAges 1 month–35 years - NCT05875155Recruiting
Saving eggs by freezing ovarian tissue during cancer or surgery care
This trial looks at freezing ovarian tissue to help protect future fertility for people who may lose ovarian function from medical treatments or ovarian surgery. It may help you preserve the chance to have children later when egg or embryo freezing alone isn’t an option.
Pittsburgh, PennsylvaniaAges Up to 39 years - NCT06042140Recruiting
Umbilical cord patch for spina bifida repair before birth
This study tests whether a patch made from donated umbilical cord can help repair spina bifida in the womb using a minimally invasive fetoscopic approach. If successful, it may reduce the need for more invasive open fetal surgery.
Houston, TexasAges 18 years+ - NCT06063551Recruiting
Freezing testicular tissue to protect fertility in boys with cancer
This study freezes a small piece of testicular tissue from boys with cancer before they start treatment that could cause permanent infertility. The tissue is stored so that, in the future, it might help them have biological children.
Edinburgh, LothianAges 1 day–18 years - NCT06692049Recruiting
Freezing gonadal tissue to preserve fertility in children with a disorder of sex development
This study tests a procedure that freezes and stores gonadal tissue (tissue that makes eggs or sperm) to help preserve the chance of having biological children in the future. It is for children and young adults under 30 who have a disorder of sex development and either have a risk of cancer in that tissue or will have it removed for another medical reason.
Chicago, IllinoisAges Up to 30 years - 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 - NCT06764719Recruiting
Hair follicles for cell therapy
This trial tests if special hair follicles can be used for cell replacement therapy in disease. It may help people with certain medical conditions.
Toronto, QuebecAges 18–80 - 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 - NCT06935110Recruiting
Windpipe repair with donated aortic patch
This trial tests whether a special patch made from donated tissue (aorta) can help repair damaged or missing parts of the windpipe. It is for people with serious windpipe problems who cannot have standard surgery.
TaipeiAges 18 years+ - 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 - NCT01558544Recruiting
Freezing ovarian tissue for future fertility after early menopause risk
This study looks at freezing (cryopreserving) ovarian tissue in people who are at risk of early menopause because of cancer treatment or surgery. It may help preserve natural hormone function and possible future fertility for those who cannot or do not want to freeze eggs or embryos.
New York, New YorkAges Up to 45 years - NCT03180918Recruiting
Freezing testicular tissue before very fertility-damaging cancer treatment
This trial studies whether freezing a small piece of testicular tissue before certain aggressive cancer treatments can help preserve future fertility. It is meant for children or teens who face a high risk of infertility from specific treatments when usual sperm freezing is not possible.
BaselAges 3 months–18 years - 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 - 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 - 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 - 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.
BrusselsAges 18 years+ - NCT06253507Enrolling by invitationPhase 1/Phase 2
Gene therapy for p47 chronic granulomatous disease
This trial tests a new gene therapy for people with a specific type of chronic granulomatous disease (p47 CGD). The treatment uses your own blood stem cells, which are modified in a lab to help your body fight infections better. It is for people who do not have a matched stem cell donor and have had serious infections.

Common questions
- Are there clinical trials for cryopreservation?
- Yes. Clin2 currently lists 44 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.
