How to prepare for Stuhlprobe Männer

Preparation for a stool sample (specifically for men) depends on the test kit used. Generally, avoid high-fiber or processed foods, alcohol, and prebiotics for 3–5 days before collection, as they can temporarily alter gut bacteria. Antibiotics and proton pump inhibitors should be paused if medically safe. Collect the sample from the first morning stool, avoiding urine or water. There are no male-specific preparation steps, but hormonal factors like testosterone may influence the microbiome—this is not controlled by diet. Evidence is based on common lab practice, not clinical trials. Always follow the manufacturer's instructions. Caveat: Improper preparation may invalidate results.
