    Does vasectomy change the colour of the ejaculate?

Hi, I had a vasectomy about a year ago and since then the coulour of the ejaculate has changed to almost clear with a little white (which i think is normal) but recently it has taken on a darker colour (cant tell if its dark green or light brown) as if whatever is coulouring it is in very small quantities. I have noticed this over the last couple of weeks. I have not had any injury directly to my testees but do run at least once a week.

Hi greetings
Vasectomy is disconnecting the passage ,called as vas differens of sperm from epididymis and testis .During ejaculation sperm from epididymis is pumped out and get mixed by the semen secreted by seminal vesicle and prostate gland. Majority of (around 90 to 95 %) semen is from seminal vesicle and prostate.
So after Vasectomy it can become more clearer and thin because it doesn't contain sperm, but it depends on how frequently you masterbate.?
Now the colour has changed to brown or dark means possibility of an infection has to be ruled out.
Either it could be seminal vesiculitis , prostatitis or any trauma causing minor bleeding inside your genital system.
I would like to test your urine and semen .If abnormal I suggest you to consult a urologist for further evaluation.
Hope you are convinced. Regards
