Hospitalization rates in vasectomized men
A. M. Walker, H. Jick, J. R. Hunter, A. Danford and K. J. Rothman
Six thousand ninety-two men who had undergone vasectomy were observed for
20,491 person-years of observation in a prepaid group practice. The
incidences of first-time hospitalizations for a variety of diagnoses were
examined as a proxy for disease incidence rates and compared with similarly
derived rates in the remaining male membership of the practice.
Vasectomized men had comparatively high rates of hospitalization for a
variety of diseases of the genitourinary system during the early
postvasectomy period. Apart from these, there were no important,
statistically convincing elevations in the new hospitalization rates among
vasectomized men, as compared with those of the nonvasectomized comparison
group.
