Grand Forks clinic offering vasectomies Published March 9, 2012 GRAND FORKS AIR FORCE BASE, N.D -- The 319th Medical Group clinic is once again offering vasectomies, according to medical officials. A vasectomy - a permanent form of birth control - is 99.85 percent effective; is safer, cheaper and comes with a lower risk of complications than tubal ligation in women; and only takes about 20 to 30 minutes, according to the clinic. Those interested should only consider a vasectomy if they are sure they do not want to have a child in the future. Contact the clinic at 747-5601 for more information.
