IUCD can be a coil, loop, triangle, or T in shape; its material can be impregnated with a pharmaceutical agent. The primary action of all IUCDs is the induction of a foreign-body reaction within the endometrium. This sterile inflammatory process is toxic to gametes, primarily spermatozoa, and effectively prevents viable sperm from passing into the fallopian tubes. The copper-bearing device has an independent toxic effect on spermatozoa. The progestin-releasing devices produce changes in endometrial architecture and function that reduce the potential for implantation of a fertilized egg. The progestin effect on the cervical mucus also reduces the penetrability of sperm.
