There are three types of vasectomies:
No-scalpel vasectomy – a minimally invasive procedure where a small opening is created through which the surgeon guides instruments to remove the vas deferens. This method usually doesn’t require stitches and, therefore, has a reduced risk of bleeding and infection. The tiny puncture usually heals quickly.
Open-ended vasectomy – where the tubes of each vas deferens are cut and allowed to hang free, allowing sperm to mix with other fluids and be ejaculated during orgasm. The ends can also be cauterised (burned closed) for added protection against pregnancy. No stitches are required since the opening is large enough for the tubes to be slipped out.
Closed-end vasectomy – a traditional vasectomy where the ends of each tube are cut and cauterised, and the tubes are tied off so that sperm can’t mix with other fluids or be ejaculated during orgasm. This method requires stitches for closure.
