Read the given passage and answer the questions that follow :-
The regulation of conception by preventive methods or devices to limit the number of offspring is called birth control or contraception. This basically prevents fertilisation. An ideal contraceptive should be user friendly, easily available, effective and reversible with no or least side effects. It also should not interfere with the sexual drive, desire and the sexual act of the user.
Which of the given intra-uterine devices (IUDs) is hormone-releasing?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Both (2) and (3)
Intra-uterine devices (IUDs) are grouped by what they release. Non-medicated IUDs release nothing, copper-releasing IUDs release Cu ions, and hormone-releasing IUDs release a hormone. Besides the usual IUD actions, the hormone-releasing ones make the uterus unsuitable for implantation and the cervix hostile to sperms. LNG-20 and Progestasert are both hormone-releasing IUDs.
Option (1) Multiload 375 — Incorrect. Multiload 375 is a copper-releasing IUD, like CuT and Cu7.
Option (2) LNG-20 — Correct statement, but it is only one of the correct points, so on its own it is not the answer. LNG-20 is a hormone-releasing IUD.
Option (3) Progestasert — Correct statement, but it is only one of the correct points, so on its own it is not the answer. Progestasert is a hormone-releasing IUD.
NCERT Extract:
Population Stabilisation and Birth Control – “… 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). IUDs increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilising capacity of sperms. The hormone releasing IUDs, in addition, make the uterus unsuitable for implantation and the cervix hostile to the sperms.”
