Identify the terminal methods to prevent pregnancy.
A. Tubectomy
B. Vasectomy
C. IUDs
D. Cervical caps
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A and B only
A terminal method is one that ends the possibility of any more pregnancies. Such methods are the surgical methods, called sterilisation; they block the transport of gametes.
A. Tubectomy — Correct. Sterilisation of the female: a small part of each fallopian tube is removed or tied up, so the ovum cannot reach the uterus.
B. Vasectomy — Correct. Sterilisation of the male: a small part of each vas deferens is removed or tied up, so sperms cannot pass out.
C. IUDs — Incorrect. Intra uterine devices such as CuT are placed in the uterus and can be removed when a child is wanted. They are spacing methods, not terminal ones.
D. Cervical caps — Incorrect. A cervical cap is a barrier method used at each intercourse; it is reusable and temporary.
NCERT Extract:
Population Stabilisation and Birth Control – “… Surgical methods, also called sterilisation, are generally advised for the male/female partner as a terminal method to prevent any more pregnancies. Surgical intervention blocks gamete transport and thereby prevent conception. Sterilisation procedure in the male is called ‘vasectomy’ and that in the female, ‘tubectomy’. In vasectomy, a small part of the vas deferens is removed or tied up through a small incision on the scrotum (Figure 3.4a) whereas in tubectomy, a small part of the fallopian tube is removed (Figure 3.4b) or tied up through a small incision in the abdomen or through vagina. These techniques are highly effective but their reversibility is very poor.”
