Hello and welcome to the zero to finals podcast.

My name is Tom and in this episode I'm going to be talking to you about coils.

Then you can find written notes on this topic at zero to finals.com slash coils

or in the contraception section of the zero to finals obstetrics and gynecology book.

So let's get straight into it.

Coils are devices inserted into the uterus that provide contraception.

They are a form of long-acting reversible contraception.

Once fitted, they work for a long time, and removing the device restores fertility.

There are two types of intrauterine device, or coil.

The copper coil, abbreviated to CU-IUD, which contains copper and creates a hostile environment for pregnancy, and the

Levo-Norgestrel intrauterine system, abbreviated to LNG-I-U-S, and this contains progestogen

that's slowly released into the uterus. Both types of coil are more than 99% effective at preventing pregnancy when they're properly

inserted.

Fertility returns immediately after removal of an intrauterine device.

Atoms it for you, often the two types of coil are referred to as the intrauterine device or IUD and the intrauterine

system or IUS. The intrauterine device refers to the copper coil and the intrauterine system

refers to the coil with hormones, specifically leavenorgestrel, for example, the myrina

coil. The way to remember this is that the copper coil is just a device, whereas the hormones

in the myrina coil make it a system. Let's talk about the contraindications. The contraindications

for inserting a coil are pelvic inflammatory disease

or pelvic infection, immunosuppression, pregnancy, unexplained bleeding, pelvic cancers and uterine

cavity distortion, for example by fibroids. Next let's go through insertion and removal of the coil.
