Describe the surgical methods of birth control (i) for men, and (ii) for women.
(i) Vasectomy: In male, a small portion of the Vas deferens is removed and both the cut ends are ligated properly. This prevents the sperms from coming out.
(ii) Tubectomy- In female, a small portion of the fallopian tube is removed and the cut ends are ligated. This prevents the entry of ovum into the oviducts.
