Why do men undergo vasectomy surgeries during the national college basketball tournament?

Vasectomy, the procedure that removes the vas deferens, the ducts that carry sperm produced in the testes, is a widely performed form of male contraception. In the United States, there has been a surge in men undergoing vasectomies in March and April, coinciding with the college basketball tournaments, and the science media outlet Science Alert has explained the reasons for this.

In the United States, the NCAA Men's Basketball Tournament is held every year from March to April. This tournament features 68 schools from the top category of the National Collegiate Athletic Association (NCAA) competing in a tournament format, and is a major event that attracts attention from all over the country, often referred to as 'March Madness' or 'Big Dance.'

According to data from a major US insurance claims data source from 2007 to 2015, there is a tendency for the number of vasectomy procedures to increase in March, when March Madness begins. This trend is known as 'Vas Madness' and is now a widely recognized phenomenon.

At first glance, there seems to be no connection between basketball tournaments and vasectomies. However, Dr. James Dupree of the University of Michigan Medical School points out that 'major sporting events are popular times for men to get vasectomies because doctors advise them to rest for two to three days after the surgery.'

In other words, since a vasectomy requires several days of rest, many men think, 'I might as well get the vasectomy done when I can stay home and watch March Madness.'

Vas Madness was also pointed out in

a paper published in 2018 by urologists at the University of Washington. However, that paper reported that the number of vasectomy surgeries increases not only in March, but also at the end of the year.

The research team speculates that this is because, as the end of the year approaches, the total amount of medical expenses paid by patients reaches the insurance deductible, resulting in a lower actual burden. In other words, after paying a large amount of medical expenses throughout the year, the amount reaches a level where the insurance company's share of the cost becomes too high, so many men may think it's better to get a vasectomy while it's still affordable.

Furthermore, Science Alert suggests that Vas Madness may be a form of ' self-fulfilling prophecy .' Self-fulfilling prophecy refers to the phenomenon where people who hold certain expectations or beliefs act in accordance with them, making those expectations more likely to come true.

Vas Madness first gained attention in 2008. At the time, a urology clinic in Oregon ran a radio ad urging people to 'get a vasectomy at the Oregon Urology Institute the day before the tournament starts' as March Madness approached. This became an explosive trend, and various clinics reportedly jumped on the bandwagon with their own campaigns.

Science Alert points out that these campaigns may have led to an increase in men undergoing vasectomies in March. The chain reaction of news articles, Vas Madness promotions, and research papers may have resulted in a surge in vasectomies in March that exceeded initial demand.

While Vas Madness may be somewhat artificially induced, some argue that it offers tangible benefits to patients. In a 2023 article, urologist Alexander Rozanski stated, 'Getting men to follow instructions, relax, and avoid strenuous exercise and activity during their recovery period after a vasectomy can sometimes be difficult. March Madness provides a great excuse for them to rest and recover.'
