How many times has this happened?
Is it occurring only with ejaculation or at other times as well?
Are you having any other symptoms?
Thank you for the additional information.
There are several possible causes of bleeding through the penis. An isolated episode of bleeding is most often from a ruptured small blood vessel and does not require further investigation. Since you have had 6 episodes of bleeding, then it is more likely to be due to another condition. It can be related to a chronic or recurrent infection of the urethra (the tube through the penis) or the prostate. This can include bacterial infections or a herpes infection in the urethra. It can be due to prostate stones. It can be due to growths within the male genital tract, including papillomas or cysts. It is not common that bleeding is due to cancer, but it is possible. Conditions within the bladder would usually cause blood in the urine rather than separate bleeding through the penis. It is also possible that bleeding through the penis can be a manifestation of systemic illnesses that cause an increased risk of bleeding, such as liver disease, It would require an appropriate evaluation to determine which of these conditions are present.
