NCT ID NCT07330869
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study will follow 90 men aged 18-50 who need heart surgery, some of whom will take the blood thinner warfarin afterward. Researchers will track changes in sperm count, movement, shape, DNA health, and hormone levels over 12 months. The goal is to see if warfarin harms male fertility, which could help doctors better counsel patients about family planning.
