Which one of the following is most widely accepted method of contraception in India?

IUDs

The correct answer is Option (3) - IUDs

An effective and popular method of contraception is the use of Intra Uterine Devices (IUDs). These devices are inserted by doctors or expert nurses in the uterus through the vagina. 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).

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. IUDs are ideal contraceptives for the females who want to delay pregnancy and/or space children. It is one of most widely accepted methods of contraception in India.
