(d) : At present the most widely accepted method of contraception in India is $IUDs. $ These Intra Uterine Devices $(IUDs) $ are presently available as the non­ medicated $IUDs\ (e.g.,$ lippes loop), copper releasing $IUDs\ (CuT, Cu7,$ Multiload $375)$ and the hormones releasing $IUDs$ (Progestasert, $LN-G­20$). $IUDs$ increase phagocytosis of sperms within the uterus and the Cu­ions released suppress sperm motility and the fertilizing capacity of sperms. The hormone releasing $IUDs$ make the uterus unsuitable for implantation and cervix hostile to the sperms.
