IUDs are contraceptive devices which are placed inside the uterus. Small, flexible plastic frame. Has copper wire or copper sleeves on it. Inserted into a woman‘s uterus through her vagina.
Preventing sperm and egg from meeting. Perhaps the IUD makes it hard for sperm to move through the woman‘s reproductive tract, and it reduces the ability of sperm to fertilize the egg. Prevent the egg from implanting itself in the wall of the uterus.
- IUCDs prevent pregnancy by making the endometrium unreceptive to the fertilized ovum. Stimulates the endometrium to release leukocytes (WBCs) and prostaglandins making it hostile to the sperm.Causes bizarre and irregular growth of the endometrium.
- Prevents implantation of a fertilized ovum. IUDs like Copper-T‘s also come wrapped in copper. Copper is toxic to sperms and is a method of enhancing the contraceptive effect of the IUDs.
- The IUCDs can come in various shapes and sizes.
