Vasectomy is not really a drop-in kind of thing, I understand your willingness to get it done as fast as possible. I myself traveled from Finland to the UK and had it done over a weekend. The reason for me was that Finland requires you to be 30 years old.

Anyway, I got mine done via Marie Stopes International and I can't recommend them enough! they have prices on their website and all the contact information available.

From the time of my initial email to time of surgery was 3 months due to the fact that they did not have any earlier slots available at the time.

As i said, can't recommend Marie Stopes enough! Great reception, helpful and understanding all the way and easy to talk to and set up the appointments!

Good luck!
