It's common to have blood in your semen in the first few ejaculations after a vasectomy. This isn't harmful.
It is advised that you wear close-fitting underwear, such as Y-fronts, to support your scrotum and help ease any discomfort or swelling. Make sure you change your underwear every day.
It is safe for you to have a bath or shower after your operation –make sure you dry your genital area gently and thoroughly.
Most men will be fit to return to work one or two days after their vasectomy, but you should avoid sport and heavy lifting for at least one week after the operation. This is to minimise the risk of developing complications.
