Nexplanon implant

The contraceptive implant is a 4cm long matchstick sized device that contains Etonogestrel. Etonogestrel is a synthetic progesterone hormone that is slowly released over 3 years into the bloodstream. It works by inhibition of ovulation (egg release) and also causes changes in the cervical mucus, which hinders the passage of sperm into the womb. It is a very reliable contraceptive (>99% prevention rate) and is great for people who struggle to take pills daily. The amount of progesterone hormone is very low and even people who are quite sensitive to progesterone tend to tolerate the Nexplanon well. The main side effect in a small proportion of women is erratic bleeding.

Mirena

The Mirena is a T-shaped progesterone releasing device that sits snugly in the uterus. It contains 52 mg of Levonorgestrel, a synthetic progesterone, which it releases slowly. This has the effect of reducing the thickness of the uterine lining, preventing pregnancy. Very little progesterone enters the bloodstream and therefore it is well tolerated. Once fitted it can be relied upon for 5 years for effective and reversible contraception.

It is fantastic for reducing menstrual blood flow and painful periods and saves many women from having surgical management for these issues. For many people it is a healthy way to stop periods altogether and can be one less thing to worry about.

If you are going through the perimenopause or menopause, the Mirena can be used in conjunction with an oestrogen as part of a hormone replacement therapy (HRT) regimen to protect the lining of your womb, and as a method of contraception.

Kyleena

Kyleena is also a T-shaped intrauterine delivery system which is placed inside the womb. It slowly releases a low dose of the hormone levonorgestrel (19.5 mg). It works at preventing pregnancy for 5 years. Kyleena reduces the monthly growth of the lining of the womb and thickens the cervical mucus. Periods can still be present but are often much more manageable. It is useful for use in patients who are more sensitive to the effects of progesterone.

Copper IUD

The Copper IUD is a T-shape plastic device with copper wire wrapped around the stem and the arms. Copper inhibits sperm movement and also prevents implantation of embryos into the womb lining. It is excellent as an Emergency Contraceptive and can be used up to 5 days after unprotected sex with a >99% prevention rate. In the Clinic we fit devices that last up to 10 years. It is a great option for people who do not tolerate hormonal contraceptives well. You will have a natural hormone cycle. However, it can make your periods heavier and more painful so is best fitted in people whose periods are light.

Having an Intrauterine device fitted for some women can be a little uncomfortable. We strive to give time and maximise techniques needed to make the procedure as pain free as possible.
