Vasectomies are a birth control mechanism for men where the vans deferens is snipped so as to prevent sperm from your semen. They have been shown to dramatically improve the sex lives of men and increase satisfaction of their partners.
Studies found that in most men who had undergone the procedure, they had better sex drive.
Vasectomies also cause some men to have longer lasting erections.
Men are also three times more likely to get an increase in their sexual activity and generally enjoy sex more.
This could be due to the removal of stress of potentially getting their partners pregnant.
