Recruiting studies
- NCT05378347Recruiting
Compare two aortic stent graft types for AAA
This study compares two commercially used stent graft devices to treat an enlarged abdominal aorta (AAA). It aims to see which device works better and is safer over follow-up visits.
Loma Linda, CaliforniaAges 20 years+ - NCT05318534RecruitingPhase 1
Testing a new medicine for Cold Agglutinin Disease
This Phase 1 study checks whether an investigational medicine is safe and tolerable, and how the body processes it. For people with Cold Agglutinin Disease, it also looks at early blood markers of whether the disease responds.
LeedsAges 18 years+ - NCT05249634RecruitingPhase 2
Testosterone treatment study for men with chronic kidney disease
This Phase 2 study tests whether testosterone therapy can help men with chronic kidney disease who have low testosterone and related symptoms. It looks to see if treatment is safe and beneficial, while carefully checking heart, blood, prostate, and clotting risks.
St Louis, MissouriAges 18–85 - NCT04953130RecruitingPhase 4
HPV vaccine for boys in Tanzania
This trial studies whether giving one dose of the HPV vaccine to boys, in addition to vaccinating girls, helps protect more people from HPV-related cancers. Boys aged 14-18 who live in certain communities in Tanzania may be able to take part.
MwanzaAges 14–18 - NCT04798469RecruitingPhase 2
Testosterone to reduce long-term spine pain in men on opioids
This Phase 2 study tests whether taking testosterone can lessen chronic non-cancer spinal pain in men who have low testosterone while using opioid pain medicines. It may help by improving hormone levels that could be affecting pain and overall wellbeing.
Boston, MassachusettsAges 18 years+ - NCT04574076Enrolling by invitation
Study of Esperoct for boys and men with hemophilia A
This study follows male participants with hemophilia A who are already taking Esperoct® as preventive (regular) treatment. It aims to learn how well this medicine works in real-world use and monitor safety over time.
ViennaAges Any age - NCT04526353RecruitingPhase 2
Oxybutynin for young boys with posterior urethral valves
This trial tests whether early use of oxybutynin can improve bladder and urine behavior in very young boys with posterior urethral valves. It is mainly for babies whose bladder tests show problems even after valve surgery.
BordeauxAges 3 months–6 months - NCT04452305Recruiting
Frozen testicle tissue transplant to restore fertility
This study tests using previously frozen (cryopreserved) testicle cells or tissue to regrow testicular tissue. If you’ve had cancer treatment that can harm fertility, this may help restore natural fertility potential using your own tissue.
Pittsburgh, PennsylvaniaAges Any age - NCT04298255Recruiting
Testicular injection therapy for certain causes of male infertility
This trial studies a special lab procedure where selected immature sperm cells are injected to help infertile couples achieve pregnancy. It is designed for couples where the man has a specific type of sperm-making problem found during a testicular sperm extraction.
Winston-Salem, North CarolinaAges 18 years+ - NCT03745924Enrolling by invitation
Study of Rebinyn for boys and men with Hemophilia B
This study follows males with Hemophilia B who are already on preventive (prophylaxis) treatment with Rebinyn/Refixia (a factor replacement medicine). It mainly looks at safety and how treatment is used over time, especially in people starting or continuing this prophylaxis plan.
ViennaAges Any age - NCT03803332Recruiting
Therapies for PTSD from military sexual trauma compared for adults
This trial compares two types of talk therapy to treat PTSD caused by military sexual trauma. It aims to see which therapy helps symptoms better and how well people can complete weekly outpatient sessions.
New York, New YorkAges 18–85 - NCT03093909RecruitingPhase 1
Breathing treatment with gemcitabine for lung cancer spread
This early-stage trial studies an inhaled (aerosol) form of gemcitabine to treat solid tumors that have spread to the lungs. It aims to see whether this lung-focused treatment is safe and how well it might work when standard curative options are not available.
Houston, TexasAges 12–50 - 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 - NCT03258658RecruitingPhase 1
Testing a personalized urethra repair made from your own tissue
This early study tests whether an engineered urethral patch made from your own body tissue is safe and workable for urethral strictures (narrowing that blocks urine flow). It is mainly looking for safety and how feasible the procedure and follow-up are, not proven cure yet.
San Francisco, CaliforniaAges 21–75 - NCT02641769RecruitingPhase 1/Phase 2
Stem cell injection into testicles for infertility
This trial tests whether injecting your own stem cells into your testicles can help your body start producing sperm. It is for men whose infertility is caused by a sperm-making problem rather than a blockage.
Amman, Amman GovernorateAges 21–50 - NCT01467869Recruiting
Male fertility study for men with spinal cord injury
This study looks at fertility (the ability to father a child) in men who have a spinal cord injury. It compares them with healthy men to understand how spinal cord injury may affect fertility.
Miami, FloridaAges 18–50 - NCT01248533Enrolling by invitation
Screening for abdominal aortic aneurysm in 65-year-old men in Oslo
This study is offering screening to check for an abdominal aortic aneurysm, a bulge in a major blood vessel in the belly. It may help find a problem early so it can be monitored or treated sooner if needed.
Ages 65–65 - NCT00250159Recruiting
Natural history study for hormone-related excess androgen
This study follows people who may have too much “androgen” (a hormone) to learn what causes it and how it changes over time. You may be followed even if the exact cause is not yet known, and your results may help doctors better understand these conditions.

- How do I know if I qualify for a male 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 male 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.
