(a) : The structure labelled as 1,2 and 3 are respectively fallopian tube, uterus and cervix.\ The CuT and Lippes loop are types of an intrauterine device (IUD) to be inserted by doctors or expert nurses in the uterus (labelled as 2) through the vagina. Intrauterine devices fitted inside the uterus and prevent the implantation of fertilised ova. The Lippes loop is a nonmediated IUD whereas CuT is Copper releasing IUDs that suppress sperm motility and the fertilising capacity of sperms.\ Cervical caps, vaults and diaphragm are the barriers made of rubber that are inserted into the female reproductive tract to cover the cervix (labelled as 3 ) during coitus.
