Despite it not being the most popular choice for your first method of contraception, many professionals would probably recommend the hormonal coil due to its effectiveness. When inserted, it is more than 99% effective plus you won’t have to think about it until it is removed.
But which type of hormonal coil (aka intrauterine system or IUS) is best for you?
Jaydess vs Mirena vs Kyleena vs Levosert: the facts
The Jaydess, Kyleena, Mirena and Levosert coils all contain the hormone levonorgestrel (a form of progestogen) which works to prevent pregnancy. For contraception the Jaydess is licensed for use for up to three years, the Mirena and Kyleena coils for up to 5 years and Levosert for up to 6 years.
Each coil is made from a small T-shaped frame. The Kyleena and Jaydess coils are slightly smaller than the Mirena and Levosert coils. The Kyleena and Jaydess both have a silver ring which means they can more easily be identified on ultrasound scans. Whilst the Levosert and Kyleena have blue threads the Mirena and Kyleena have brown threads.
What are the benefits of the different hormonal coils?
The Mirena and Levosert coils is also used in the management of heavy periods as they tend to make periods lighter. The Mirena coil is the only hormonal coil licensed as part of hormone replacement therapy (HRT), which is used to manage the symptoms of the menopause. Both the Mirena and Levosert coils may help to reduce pain associated periods, endometriosis and adenomyosis.
There is some evidence which shows the Kyleena and Jaydess coils reduce menstrual bleeding but neither are currently licensed for the treatment of heavy periods (unlike the Mirena or Levosert).
How are the Jaydess, Kyleena and Mirena coils fitted?
All coils have the same insertion process:
A hormonal coil can be fitted at any time in your menstrual cycle as long as you are not pregnant or at risk of pregnancy. If it’s fitted in the first five days of your cycle, you will be protected against pregnancy right away. If fitted at any other time you should use additional contraception such as condoms for 7 days after fitting.
Having an IUS fitted can be uncomfortable, and some people might find it painful, but you can have a local anaesthetic to help. Discuss this with your GP or nurse beforehand.
An appointment takes around 15 – 20 minutes and fitting the coil normally takes no longer than five. The vagina is held open, like it is during a smear test, and the coil is inserted through the cervix (the neck of the womb) and then into the womb.
After getting it inserted, you may be advised to take it easy and to take painkillers if you feel any discomfort. Your doctor or nurse will teach you how to feel for the threads that extend from the coil into the vagina (only a short way). Checking these threads regularly lets you know the coil is in place. If you can’t feel the threads the coil may not be in place and you may not be protected from pregnancy. In this case contact your nurse or doctor to see if you need emergency contraception and use an additional method such as condoms.
It is possible but unlikely, to have an infection after getting the coil fitted. Symptoms include pain in your lower abdomen, a high temperature and a smelly discharge. In this case contact your doctor urgently or return to the clinic where your coil was fitted.
Mirena vs Jaydess vs Kyleena: side effects
Now you know the technical ins and outs of the hormonal coils, but would do people who have tried them say? Below we’ve included some stats from our Lowdown user reviews and you can check out our contraception pages to see our reviewer data in depth for yourself. We need more reviews for the Levosert coil so those stats aren’t shown here.
The IUS coil and acne
For the Jaydess coil, 34% of women said it increased their acne and for the Mirena, 43% said the same. 54% of respondents said the Kyleena coil increased their acne.
The IUS coil and moods
43% of women said they felt no change in their moods when on the Jaydess, similar to 44% using the Kyleena and 45% with the Mirena.
The IUS coil and periods
Almost two fifths (37%) of women said their periods stopped with the Jaydess coil and a higher 57% said the Mirena coil stopped theirs.
With the Kyleena, 35% of women said their periods stopped completely.
The IUS coil and sex drive
What about your sex drive people? Well luckily, the majority if respondents felts there was no change in their sex drive – aka hornyness – on all the coils. For Jaydess, 57% said there was no change and 47% said the same for Mirena.
However, whilst two-fifths (38%) of Kyleena users said there was no change in their sex drive, the same number (38%) said lost their sex drive. 29% said they felt a decrease in sex drive whilst using the Jaydess coil and a similar percentage (27%) said the same for the Mirena.
The IUS coil and weight gain
In terms of weight gain, two thirds (62%) of participants said there was no change on the Mirena, a slight increase of 65% said the same for the Jaydess. Likewise, the majority (60%) of reviewers said the same for the Kyleena.
What do the reviews say?
“My periods became very irregular- would stop for 3-4 months then be very light for 10 days or so which I found annoying. Other than that it was great! I asked for local anesthetic when they put it in too which made it a lot less painful.”
“I had the Jaydess inserted after a good experience with the Mirena coil. it was a huge mistake for me. I didn’t stop bleeding for 3 months and just generally felt awful. My gyno recommended taking it out as it turned out I had an infection that wouldn’t clear up with antibiotics and my vagina has never been the same since. It gets really dry, sensitive and I suffer from dermatitis/eczema. It also caused me to have a cyst which then burst and bled into itself. Once I had the Jaydess removed the infection cleared up as well as the cyst but I still suffer from awful eczema.”
“Best contraception I’ve ever used. Minor side effects, lighter periods with very little pain, better skin, no weight gain, no worries – what’s not to love about it? Have mine in 2 years and will be getting a new one immediately after this one comes out.”
Mirena coil reviews
“Would have been great but pretty sure it’s the reason I have had chronic thrush!”
“It was painful to put in, and I had cramping occasionally (a few times a month) for quite a while afterward. I had 9 months of irregular bleeding (light spotting), but now no bleeding at all, and that is wonderful. No side effects at all apart from the bleeding initially. Amazing alternative to remembering pills.”
“I got this when I was 25 y/o after 7 years of the implant on and off, which caused bleeding. I decided to get the Mirena because the other options were exhausted (I can’t take the pill for medical reasons). I can’t lie, getting it put in did hurt – a lot – but it hurt for about 20 seconds. Before anyone tells you how painful it is, it IS worth it. After having it put in, I was fine at first and then had mild bleeding and cramps for about a week. Since then, my periods have completely stopped. I occasionally have mild bleeding after sex but I think this is unrelated. I saw a doctor at the hospital recently and she saw my Mirena on a scan, she asked me about it and then said “The Mirena has changed my life” and I can’t disagree. I had it checked by a nurse about 3 months later because I was worried that it might have moved but all is good. I’m now 8 months in and it’s amazing – I get VERY occasional, VERY mild cramps but other than that, it’s changed my life.”
Kyleena coil reviews
“I found fitting extremely painful, but the worst bit was very fast – so only intense pain for like 10 seconds. I had pretty heavy bleeding for a few days after fitting and then a more painful / heavy period the mont after and then since that have basically not had a period. I didn’t notice any change in mood, but boobs have got bigger and I’ve put some weight on (although that could be due to lockdown!). I found I got cramping for about 6 weeks after fitting, not constant but they were very uncomfortable for the first few weeks. Overall really pleased with it, worth the discomfort at the start for what will hopefully be 5 years of not having to worry about contraception!”
“All I will say with this one is give it 6 months to settle down! I had quite sore breasts on and off for the first 3 months and after the first 3 months developed quite bad acne. With an adjustment to my skin routine and 3 months of patience it’s virtually back to normal! Get the odd cramp every now and then but virtually never have periods (and if I do, they’re very light and last 1-2 days) but has settled down massively. My sex drive also returned from 5 years on the combined pill and reduced my moodswings – overall I would recommend it despite the hiccups!”
“The first month I got my coil fitted I experienced spotting every day. Three days before my period was due I had an ongoing headache that ended up me being sent home from work in tears So far I haven’t experienced any acne or mood changes but am still feeling sceptical.”
