A woman can get pregnant if a man’s sperm reaches one of her eggs (ova). Contraception tries to stop this happening by keeping the egg and sperm apart or by stopping egg production. One method of contraception is the contraceptive implant.
We have included further information about the implant below to help you make an informed choice about your contraception. After reading it, if you think the implant is the right contraception choice for you. You can register online for a telephone consultation to discuss this further with one of our clinical team or you can make an appointment to come into our walk-in and wait clinics to have your implant .
*Please note our Walk-in and wait slots are limited and can on occasion incur a 2 hour wait.
The implant can be put in at any time during your menstrual cycle, as long as you and our nurse/doctor are reasonably sure you are not pregnant. If the implant is not working for you it can be removed at any time by one of our trained doctors or nurses (appointment only).

How the implant works
The implant steadily releases the hormone progestogen into your bloodstream. Progestogen is similar to the natural hormone progesterone, which is released by a woman's ovaries during her period.
The continuous release of progestogen:
- Stops a woman releasing an egg every month (ovulation)
- Thickens the mucus from the cervix (entrance to the womb), making it difficult for sperm to pass through to the womb and reach an unfertilised egg
- Makes the lining of the womb thinner so that it is unable to support a fertilised egg
