Dr Mohamed Otify, Consultant Gynaecologist and Gynaecological Oncologist, provides expert fitting and review of both hormonal and non-hormonal contraceptive coils.
The coil is a simple, highly effective form of long-term contraception that can also help treat heavy or painful periods.

A contraceptive coil is a small device placed inside the womb (uterus) to prevent pregnancy.
There are two main types:

• IUD (Intrauterine Device) – a copper coil that alters cervical mucus, making it difficult for sperm to reach or fertilise an egg.
   
• IUS (Intrauterine System) – a plastic T-shaped coil that slowly releases the hormone progesterone (progestogen). It prevents pregnancy and can make periods lighter, shorter, and less painful.
   

Both options are more than 99 % effective and provide protection for 3 – 10 years, depending on the type.

The hormonal coil helps prevent pregnancy by:

• Thickening cervical mucus, blocking sperm from reaching the egg.
   
• Thinning the womb lining, reducing the chance of implantation.
   
• Suppressing ovulation in some women.
   

Many women also choose the hormonal coil to manage heavy or painful periods.

A typical appointment takes 15–20 minutes and includes:

• Consultation and contraception review
   
• Blood-pressure check and pelvic examination
   
• Coil fitting (hormonal or non-hormonal options available)
   
• Removal of any existing coil
   
• Written summary for you and your GP
   

The coil is inserted gently through the cervix. Two fine threads remain at the top of the vagina so the device can be checked easily.

Most women find the procedure quick, with only mild cramping or discomfort. Taking simple pain relief such as paracetamol 30 minutes beforehand can help.

Coil fitting can be performed:

• Under local anaesthetic for comfort during the procedure
   
• With sedation for women who prefer to be relaxed but conscious
   
• Under general anaesthetic for those who are particularly anxious or require additional procedures
   

Most patients tolerate the procedure well with local anaesthetic alone, but the choice depends entirely on your comfort and medical background.
Simple pain relief (such as paracetamol 30 minutes before the procedure) can also be helpful.

Mild cramping or light bleeding for a few days is normal.
You can return to normal activity immediately, though it’s best to avoid intercourse or tampons for 24 hours.
A follow-up review is usually advised after your first period.

Contact your doctor if you experience:

• Persistent abdominal pain
   
• Unusual discharge
   
• Concern that the coil may have moved or come out
   

Most coils remain effective for 3 – 5 years (hormonal) or up to 10 years (copper) before replacement.

The contraceptive coil is suitable for most women seeking:

• Reliable, low-maintenance birth control
   
• A reversible option without daily pills
   
• Relief from heavy or painful periods
