Since the first vasectomy mission to the Philippines in 2001, the NSVI Vasectomy Team has returned every year (except 2006 when all funds were donated to Katrina relief) to help prevent unintended pregnancies by providing free no-scalpel vasectomy services.
There are probably archived photos of earlier missions, but if you view photos taken from the 2010 and 2011 mission, you’ll get the idea.
