  Choose the right one among the statements given below. (a) lUDs are generally inserted by the user herself. (b) lUDs increase phagocytosis reaction in the uterus. (c) lUDs suppress gametogenesis. (d) lUDs once inserted need not be replaced.

Answer:

                  (b) Non-mediated lUDs increase phagocytosis of sperms within the uterus and the Cuions released suppress sperm motility and the fertilizing capacity of sperms. Hormonereleasing lUDs make the uterus unsuitable for implantation and the cervix hostile to sperms, e.g., progestasert, LNG-20. Intra Uterine Devices (lUDs) are used as one of the effective and popular contraceptive method. These devices are inserted by doctors or expert nurses in the uterus through vagina. lUDs are presently available as the non-mediated lUDs (e.g., Lipens loop),copper releasing lUDs (Cu-T, Cu-7, Multiload 375) and the hormone releasing lUDs (Progestasert, LNG-20). lUDs do not suppress gametogenesis as gametogenesis (oogenesis) takes place in the ovary, while lUDs are inserted in the uterus (through vagina) with the help of an doctor or an expert personnel.
