One of the following is a surgical method that prevents the sperms from reaching the ovum and pregnancy does not occur. This method is
(a) IUD
(b) Vasectomy
(c) Condom
(d) Tubectomy
Answer :
(b) Vasectomy
Vasectomy is a surgical method of contraception that stops the sperm from reaching the ovum and thus, prevents pregnancy.
Copper-T is an intrauterine device that some women use for birth control. It is a barrier. It is inserted high in the uterus by a physician and provides enhanced contraceptive protection for up to ten years. Copper IUDs actually prevent fertilization by reducing the number and viability of sperms reaching the egg, and by impeding the number and movement of eggs into the uterus.
Vasectomy is a surgical procedure where the male vasa deferentia are severed and then tied/sealed in a manner so as to prevent the sperm from entering into the seminal stream thereby preventing fertilization.
Tubectomy is the surgical procedure in which a woman's fallopian tubes are clamped and blocked or severed and sealed, either of which prevents the eggs from reaching the uterus for implantation.
A condom creates a physical barrier that prevents the sperm from reaching the egg. The barrier makes sure fertilization and pregnancy do not occur.
Thus, the correct answer is option (B), 'Vasectomy'.
