Coil Fitting and Removal
Coils provide long-acting, reversible contraception without daily medication. There are two main types: hormonal coils, which release progestogen, and copper coils, which do not contain hormones. A coil is fitted through the cervix into the womb and can remain in place for several years, depending on the type. It can be removed at any time by a trained healthcare professional, and fertility usually returns quickly after removal.
When the Service May Be Recommended
A consultation may be helpful if you:
Want reliable, long-term contraception without taking a daily pill.
Would like to compare hormonal and hormone-free options.
Have heavy or painful periods and want to discuss whether a hormonal coil could help.
Need an existing coil replaced or removed.
Are planning a pregnancy or wish to change contraception.
Experience side effects or have concerns about your current coil.
Have been told your coil threads are not visible or have had a previous difficult fitting or removal.
Your consultation will help establish which option is suitable and how the procedure can be planned around your needs.
What is a Coil (IUD)?
A coil, also known as an intrauterine device (IUD), is a small T-shaped contraceptive device placed inside the uterus to prevent pregnancy.
It is over 99% effective and can remain in place for 3 to 10 years, depending on the type.
There are two main types of coil contraception.
Hormonal Coil (IUS)
Common brands include Mirena, Kyleena, and Jaydess.
The hormonal coil releases a small dose of progestogen, which works by:
Thickening cervical mucus to block sperm
Thinning the lining of the uterus
Occasionally preventing ovulation
Benefits of the Hormonal Coil
Highly effective long-term contraception
Periods often become lighter, shorter, or stop completely
Can improve heavy or painful periods
May help manage endometriosis symptoms
Long-lasting protection for 3–8 years
Copper Coil (Non-Hormonal IUD)
The copper coil contains no hormones. Copper creates an environment that prevents sperm from fertilising an egg.
Benefits of the Copper Coil
Completely hormone-free contraception
Long-lasting protection for 5–10 years
Can be used as emergency contraception
What to Expect
Consultation
Mr Richard Flint will review your medical history, periods, current contraception and future pregnancy plans. Together you will discuss the benefits and possible risks of choosing a hormonal coil or copper coil.
Before fitting, Mr Richard Flint will check that pregnancy can be excluded. A pregnancy test and screening for sexually transmitted infections may be offered.
The procedure
Fitting the coil
A speculum is gently inserted into the vagina to view the cervix.
The uterus is measured, and the coil is passed through the cervix using a slim applicator.
The threads are trimmed so the coil can be checked and removed later.
Fitting usually takes around 5–10 minutes.
If needed, pain relief options, such as local anaesthetic, will be discussed beforehand. For many patients, the procedure is quicker and more comfortable than expected.
Removing or replacing a coil
You may wish to remove your coil if:
It has reached its expiry date
You want to try for pregnancy
You wish to change contraception
You experience side effects
Fertility usually returns immediately after removal.
To remove a coil:
A speculum is gently inserted into the vagina to view the cervix.
The coil threads are located and gently pulled.
The arms of the coil fold upwards as it slides out.
Removal usually takes less than a minute.
Coil Removal When Threads Are Not Visible
Occasionally the coil threads may not be visible at the cervix. This can happen if they retract slightly into the cervical canal.
Specialist techniques allow the coil to be safely removed in clinic, including:
Fine retrieval instruments
Ultrasound guidance if required
In most cases, removal can still be completed during the same appointment.
Recovery
Mild period-like cramps and light spotting can occur after fitting.
You can return to normal activities when you feel comfortable, although you may prefer to rest afterwards.
A follow-up check after approximately 6 weeks may be recommended.
Frequently Asked Questions
Does coil fitting hurt?
Most patients experience short-lived cramping, similar to period pain. The discomfort usually lasts only a few minutes.
How long does a coil appointment take?
Appointments typically last 15–30 minutes, including the consultation and the procedure.
Can a new coil be fitted at the same time as removal?
Yes. If replacing a coil, removal and reinsertion can often be done during the same visit.
When can I get pregnant after coil removal?
Fertility returns immediately, so pregnancy can occur straight away.
