This trend is continuing, considering Judy Mikovits/the Chronic Fatigue communities vociferous support for anti-vaccination cranks:
The increasing incidence of mumps orchitis: a comprehensive review– There has been a recent increase in mumps orchitis among pubertal and postpubertal males. These outbreaks can be attributed to a reduction in the uptake of measles-mumps-rubella (MMR) vaccine during the early to mid-1990s in children who have now matured. The mumps virus is commonly associated with extra-salivary complications. Unvaccinated postpubertal males diagnosed with mumps virus frequently develop complications such as mumps orchitis. Therefore, it is important that urologists are familiar with the diagnosis, treatment and complications of this condition. Here we review the epidemiology, clinical presentation, diagnostic methods, treatment options and complications of mumps orchitis, as a complication of mumps virus, with particular emphasis on testicular atrophy, subfertility and infertility.
SPOILER: All those little boys not getting their MMR? They grow up, go to college/work/military, and get mumps. Little boys sometimes get swollen balls as the result of mumps infection, but young adult/adult males get it often (40% of men who get mumps, get swollen, inflamed balls. ‘most common complication’) and really bad. End result? Sub- or total infertility. 40% of men who get mumps.
Also, their balls shrink.
A very big problem is that physicians arent really used to diagnosing mumps-induced orchitis. Im not dude, but I can think of lots of reasons why a dude might have swollen balls. Mumps orchitis hasnt really been a problem since the MMR vaccine was developed, so why would it be their first thought when a guy walks into their office with swollen balls? I mean, how many of todays physicians could readily diagnose a reemerging nonparalytic polio virus vs a simple influenza infection? Its just not something a modern physician thinks about.
To top this off, swollen balls might not show up until 6 weeks after the guy has mumps! With all the other symptoms long-since resolved, Doc would have no reason at this point to think something viral is going on.
Diagnosing mumps orchitis is a problem for physicians. Theyre needing to remind one another what to look for/how to treat the pathology of mumps.
So even though the mumps vaccine was invented in 1949, because of anti-vaxers, we still get publications in the ‘British Journal of Urology’ like this, reminding everyone of the “epidemiology, aetiology, clinical presentation, diagnosis, treatment, and complications” of mumps in relation to balls, in 2010.
