IUD insertion procedure

The IUD may be a small prophylactic gadget that's put within the woman's uterus. There are two sorts of IUD. The copper IUD A little plastic gadget with copper wrapped around its stem. The Progestogen (Mirena) IUD A little T-shape gadget with a barrel containing progestogen around its stem.

How does the IUD work ?

Although the IUD has been used for more than 30 years to prevent pregnancy, how it works is still not fully understood. The IUD affects sperm movement and survival in the uterus (womb) so that they cannot reach the egg to fertilise it. The IUD also changes the lining of the womb (endometrium) so that it is not suitable for pregnancy and prevents an egg - if it does become fertilised - from developing.
