Hi there, and thank you for your question. I appreciate your concern about this issue and I shall try help where I can. What you've experienced is the presence of blood in your ejaculate. This can happen for a couple of reasons and one of them being trauma as you have mentioned. The other reason for this problem could be an infection in the spermatic cord or testicles. If the cause is due to trauma, then the issue should resolve on its own within a few days to a couple of weeks. If the problem is due to there being an infection in the above-mentioned areas, then you will need to see your primary care physician in order to assess the genitalia to make sure that there's no signs of infection. If this is the case, then you will need to go on a course of antibiotics to clear up the problem. Your doctor could also ask for a semen sample to be sent to a lab in order to have a culture and sensitivity test done in order to see what organism is causing the problem. I hope this helps and good luck.
