Solution
Intra Uterine Devices $(IUDs)$ for contraception
$(i)$ There devices are inserted by the doctors into the uterus through vagina.
$(ii)$ There are three types of $IUDs$
Non-medicated IUDs They increases the phagocytosis of the sperm within the uterus, $e . g$., Lippes loop
Copper Releasing $IUDs$ Along with phagocytosis of the sperms, the copper ions released, suppresses the sperm motility and the fertilizing capacity of the sperm.$e.g., Cu-T, Cu-7, multiload- 375$
Hormone Releasing $IUDs$ They makes the uterus unsuitable for implantation and the cervix hostile to the sperms, $e.g, progestasert, LNG-20$
