Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
(A) Diaphragms — this matches (II) Barrier method. A diaphragm is a rubber cover put into the female reproductive tract to cover the cervix. It is a physical barrier that stops the sperm from meeting the ovum.
(B) Coitus interruptus — this matches (IV) Natural method. The male partner withdraws his penis from the vagina just before ejaculation, so that no semen enters. No device or medicine is used, which is why it is a natural method.
(C) Vasectomy — this matches (I) Surgical method. A small part of the vas deferens is removed or tied up through a small cut on the scrotum. This sterilisation blocks the passage of sperms. It is very hard to reverse.
(D) Progestasert — this matches (III) Hormone releasing IUD. This intra-uterine device releases a hormone. It makes the uterus unfit for implantation and the cervix hostile to sperms. LNG-20 is another such IUD.
NCERT Extract:
Contraceptive Methods – “… Diaphragms, cervical caps and vaults are also barriers made of rubber that are inserted into the female reproductive tract to cover the cervix during coitus. They prevent conception by blocking the entry of sperms through the cervix.”
Contraceptive Methods – “… Withdrawal or coitus interruptus is another method in which the male partner withdraws his penis from the vagina just before ejaculation so as to avoid insemination.”
Contraceptive Methods – “… 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.”
Contraceptive Methods – “… These Intra Uterine Devices are presently available as the non-medicated IUDs (e.g., Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and the hormone releasing IUDs (Progestasert, LNG-20) (Figure 3.2).”
