ClinConnect Summary
This clinical trial is studying a new treatment option for men with benign prostatic hyperplasia (BPH), a condition that causes problems with urination. The trial aims to see how safe and effective a substance called 5-hydroxytryptophan (5-HTP) is for relieving symptoms related to BPH. This treatment is being compared to a commonly used medication called tamsulosin. Researchers hope that 5-HTP will improve urinary symptoms without causing the sexual side effects that some current medications do.
To be eligible for this study, participants must be male, between 50 and 75 years old, and diagnosed with BPH and lower urinary tract symptoms (LUTS). They should also have a prostate volume of at least 30 cm³. Participants in the study will be randomly assigned to take either tamsulosin or 5-HTP for six months. Throughout the trial, participants will be closely monitored for any changes in their symptoms and overall health. This could be a great opportunity for men struggling with BPH to explore a potential new treatment option.
