title: The effects of vasectomy on viscosity, pH and volume of semen in man.
abstract: The effects of vasectomy on seminal viscosity, volume and pH have been investigated in freshly emitted semen of 21 healthy men before operation and three months later. Viscosity and the pH range were decreased significantly, but the decrease of the seminal volume was not significant. Reasons of changes have been discussed.
