Evaluation of blood pressure in vasectomized and nonvasectomized men


, : Evaluation of blood pressure in vasectomized and nonvasectomized men. International Journal of Epidemiology 10(3): 217-222

This study evaluates the extent to which vasectomy might affect blood pressure thus contributing to hasten the rate of atherogenesis in men. Data were collected from 946 men, of whom 30.1% had been vasectomised; variables considered were number of years since vasectomy, weight, height, body mass and age. No significant differences were found in mean systolic or distolic blood pressure between the 2 groups of men, it was noted, however, that many men had been vasectomized only for a short period of time. When the group of vasectomized men were analyzed by multiple regression to determine the relation of blood pressure, age, body mass index, and height with time since vasectomy, a slight rise in systolic pressure was found, related with time since vasectomy. Conclusions from this investigation may not be correct for the general population since the sample studied here was nontypical and was not checked for factors such as race, diet, smoking habit, or physical fitness, which may potentially affect blood pressure. However, if the data are consistent with the hypothesis that there are no effects on blood pressure attributable to vasectomy, they also are consistent with a moderate rise in the systolic blood pressure of vasectomized males; the effect seems to accelerate with time. This problem should be further investigated on a larger number of males vasectomized for a period of 15 years or more.
