Intrauterine device method of birth control
Intrauterine device (IUD) method is a birth control technique. It’s a small T-shaped flexible plastic that is inserted by the doctor in the uterus to prevent pregnancy.
Types of IUD and their Mode of Action
Copper IUD (Paragard)- The copper wire is wrapped at the base of the device which slowly releases copper ions that act as a spermicide. The copper ions stimulate an inflammatory response during which the ovary and the fallopian tube secrete a fluid containing prostaglandins, copper ion and WBCs. The sperms get killed on coming in contact with the copper ions. Copper IUDs are inserted for 10 years.
Hormonal IUD (Minera)- The hormone Levonorgestrel- a progestin hormone is released from the vertical end of the T device makes the mucus of the cervix thick and sticky in an attempt to block the passage of sperm to the egg. Levonorgestrel is also toxic to sperm. Another mode of action is- the hormones released by this device thin the endometrium, thereby preventing implantation of a fertilized egg. Its effectiveness can last for 5 years.
