Answer» (a) The prevention of pregnancy in women (by preventing fertilisation) is called contraception. There are 3 methods of contraception: (i) Barrier method (ii) Chemical method (iii) Surgical method. (b) (i) Vasectomy – In males, a small portion of the sperm duct (Vasdeferens) is removed by surgical operation and both the cut ends are ligated properly. This prevents the sperms from coming out. (ii) Tubectomy – In females, a small portion of the oviducts is removed by surgical operation and the cut ends are ligated. This prevents the ovum from entering into the oviducts. (c) No. |
