The popularity of vasectomies during March Madness is increasing due to the NCAA Division I men's and women's college basketball tournaments, which are held every spring. Some surgeons have attributed this increase to the steady stream of games being played for men recovering from a vasectomy. The procedure, which blocks the vas deferens, a permanent form of contraception, typically takes a few days to a week and typically takes men to rest for 48 hours and moderate moderate activity soon after. David Gentile, MD, chief of the department of urology at Highland Hospital, and Jim Dupree, MD from Michigan Medicine, have also mentioned the trend. A 2018 study found that March was one of the higher-volume months for vasectomy procedures, but the highest peaks were later in the year.
