[|Human|] what is the cause of brown stain in underwar coming out of the penis?Is it dangerous? do you have to be alarmed? What should be done about it?It happens mostly at night and when defecating.I had a biopsy of the prostate about six moths ago. It was normal -no cancer.It was OK after about few weeks after biopst but started again about 2weeks ago.PLEASE NOTE THESTAIN SEAM TO HAVE A DARK DOT OR SPOT IN  THE CENTRE OF IT
[|AI|]  Hi, The dark stained fluid could be from urine or semen discharge. The urinary tract infection or seminal vesicle or prostate inflammation could be possibility. I suggest you investigate with ultrasonography of pelvis and abdomen with special emphasis on seminal vesicle and prostate. You can revert with reports to guide you further. Hope I have answered your question. Let me know if I can assist you further.
