Question

A village health worker was taking a session with women. She tells them that one has to be careful while using oral pills as a method of birth control. Wrong usage can actually promote conception. (a) Analyse the above statement and compare the merits and demerits of using oral pills and surgical methods of birth control. (b) Village women are confused as to how a thin metallic copper loop can provide protection against pregnancy. Explain the mode of action of IUDs. Give two points.

Assertion (A) : Cu-T, Cu-7 and LNG-20 are the most widely used copper-releasing IUDs. Reason (R) : Cu-ions in IUDs effectively suppress sperm motility and the fertilising capacity of sperms.
