What does IUD mean?
IUD is the abbreviation for IntraUterine Device, which is an instrument inserted within the uterus. It is a T-shaped plastic device with a string attached to its end.
What are the roles of IUDs?
The role of an IUD is to avoid sperm cells encountering an uvum. The basic IUD doesn't modify either the uterine cycle or the ovarian cycle. The ovulation happens normally, the menstruations are not induced by IUDs. If a woman has irregular cycles, the IUD won't regularize it, unlike the pill.
How does it work?
No one is completely sure about the exact way IUDs prevent pregnancy. Commonly, it is said that it affects sperm movements and prevents its survival in the uterus by making the environment more hostile. It also changes the endometrium lining, which prevents the development of an ovum, if fertilized. It may change the lining of the fallopian tubes, thus preventing the release of eggs from the ovaries.
IUDs prevent pregnancy in 98% of all cases.
What types of IUDs are there?
The two exisiting IUD types are copper IUDs and hormonal IUDs.
Copper IUDs
A cooper wire is wrapped around the stem of such devices. Copper particles released by such an IUD influence the uterus and fallopian tubes, making them produce a liquid containing copper, which kills sperm.
Hormonal IUDs
These devices contain progestin, a hormone with effects similar to those of progesterone. It prevents the endometrium from becoming too thick and makes the mucus in the cervix more sticky, so that the sperm cannot get through to the uterus.
Does an IUD protect from STDs (= sexually transmitted diseases)?
No, so condoms are highly recommended even while using an IUD.
