Resurgence of mumps orchitis among teenage boys and young men
30. March 2010 04:09
Urologists at a leading Irish hospital have reported an alarming increase in the number of teenage boys and young men developing mumps orchitis, in a paper published in the April issue of the urology journal BJUI.
They are urging colleagues to offer the MMR vaccine to unvaccinated males in the 15-24 age group and educate them about the condition, which causes one or both testicles to swell and can lead to fertility problems.
Mr Niall Davis, a Urology Research Registrar, teamed up with colleagues at the Mater Misericordiae University Hospital, Dublin, to carry out an extensive review of five decades' worth of research and statistics...
...Key findings of the review include:
? Up to 50 per cent of males with mumps orchitis will experience testicular atrophy, where one or both testicles reduce in size.
? Infertility is rare, but subfertility can occur in about 13 per cent of patients, even if their testicles have not reduced in size.
? Up to half of patients can experience abnormal sperm for up to three months after recovery and 24 per cent of adults and 38 per cent of adolescents can still have abnormal sperm up to three years after recovery.
? There appears to be a direct link between high levels of testicular swelling and increased sperm abnormalities.
? Mumps orchitis, with reduced testicular size, has been suggested as a risk factor for testicular cancer, but this association appears to be weak, with an incidence of 0.5%...
