Explanation

Birth control will not only improve the gene pool but also reduce the rate of increase in human population, which is presently a big problem. Sterilization is an effective and safest method of birth control. Sterilization of man is done by vasectomy, in which the passage of sperms is blocked either by cutting or by putting ligatures around the male duct (vasa deferentia). On the other hand, the sterilization in woman is called tubectomy where the passage of ova is blocked in fallopian tubes either by cutting or by ligaturing these tubes.
