What is
an IUD?
It is a contraceptive invented in 1928 by Ernst Grafenberg.
“It remains in place as long as contraception is desired: between 5 and 10 years depending on the model.”
Since the early 1960s, when IUDs were made from inert materials, there have been many improvements in these devices, including the use of copper.
“IUDs are the least expensive temporary contraceptive method for long-term use.”
How does the copper IUD work?
“The copper-bearing IUD is indicated as an alternative method of contraception to chemical contraceptives…”
- The IUD causes an inflammatory reaction (normal and non-infectious) of the uterine mucosa, which prevents the egg from nesting
- Copper, which is naturally spermicidal, prevents sperm from fertilizing an egg.
Contrary to popular belief, there is no contraindication to IUD insertion in a nulliparous patient. The existence of two sizes: SHA called “short” and STA called “standard” for most copper IUDs is therefore justified. Indeed, a childless woman with a smaller uterus can perfectly well have an IUD inserted, a “short” model can then be prescribed.
