Doctors should warn their patients that traces of blood in semen after a vasectomy are generally nothing to worry about, but sometimes they forget. This lack of information can lead to unnecessary confusion and concern when the man resumes normal ejaculatory activity, so it’s important to know what’s normal and what isn’t.
Is it normal to have blood in your sperm after a vasectomy?
A small amount of blood in the semen during the period immediately following a vasectomy isn’t anything to worry about. This issue often resolves itself and isn’t an indication of a larger problem.
During the operation, small amounts of blood can enter the vas deferens. This blood can find its way into the semen and may be visible during ejaculations. After a number of ejaculations, this blood is cleared from the reproductive tract and shouldn’t come back.

When to call the doctor
As a general rule, you should get in touch with your doctor if you have any concerns about how you’re recovering after a vasectomy. If you’re seeing blood in your semen and it’s worrying you, make the call!
Having said that, most doctors would probably tell you that you don’t need to worry unless you’re still seeing blood in your ejaculatory fluid after more than a week.
You should also call your doctor if you’re seeing lots of blood, or if the blood is accompanied by any kind of unusual pain.
