This study tests whether applying tranexamic acid (TXA) directly to the colon during a colonoscopy can reduce bleeding when removing large polyps. About 200 adults who need polyp removal will take part. The goal is to see if this simple step makes the procedure safer.

This study compares two surgical methods—suction curettage and hysteroscopy—for treating early pregnancy loss in women who conceived through IVF. About 50 participants will be randomly assigned to one procedure, and doctors will check for uterine scarring after 6-8 weeks. The goa…

This small pilot study is exploring whether hyperbaric oxygen therapy (HBOT) can help men with low sperm count (oligospermia) improve their fertility. Researchers will measure changes in sperm count, shape, and movement before and after treatment. The study aims to enroll 15 men …

This study tests whether breathing pure oxygen in a pressurized chamber (hyperbaric oxygen therapy) can reduce depression in people who had a stroke 6 months to 7 years ago. About 142 adults aged 50-85 who are already on antidepressants will receive either real or sham treatments…

This study tests whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can help people recover faster after anterior cruciate ligament (ACL) knee surgery. About 40 adults aged 18-45 with an ACL tear will be randomly assigned to receive HBOT or standar…

This study tests whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can improve thinking, memory, and other symptoms in people with long COVID. About 91 adults who have had cognitive problems for at least 3 months after a COVID infection will recei…

This study looks at people who had a traumatic brain injury and completed hyperbaric oxygen therapy (HBOT) 1 to 4 years ago. Researchers want to see if the thinking improvements from HBOT are still there. About 100 adults will take computer tests and answer questionnaires about m…

This study looks at how two different ways of measuring the brain—EEG (which records electrical activity) and MRI (which shows structure and blood flow)—are related. Researchers will compare these scans in 1,500 adults who already had an MRI. The goal is to better understand brai…

This study compares two techniques—intermittent hypoxic training (breathing low-oxygen air) and hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber)—to see which one improves aerobic performance in athletes. About 66 healthy, active athletes aged 18-45 will …

This study looks at whether breathing in extra oxygen can help healthy adults produce more muscle force during a mid-thigh pull test. About 48 physically active people aged 18-45 will take part. Each person will try both the oxygen treatment and a placebo (sham) to see if there's…

This study will measure how hyperbaric oxygen therapy (HBOT) changes the number of blood-forming stem cells in the body. Researchers will take blood samples from 60 adults aged 20 to 80 who are already scheduled for HBOT for other reasons. The goal is to see if HBOT can increase …

This study is checking if toxins from moldy food (mycotoxins) can be found in breastmilk and whether they affect a baby's growth and development. Researchers will test milk from 150 mothers in Israel and ask about their diet. The goal is to understand if these toxins pose a risk …
