Contraceptive implant
The implant is a small, flexible rod that’s placed under the skin in your upper arm and can be left for up to four years. It works by releasing the hormone progestogen which stops the ovary from releasing an egg and thickens the cervical mucus to make it difficult for sperm to enter the womb. It also thins the lining of the uterus to prevent a fertilised egg implanting.
We strongly recommend that you watch the film below (reproduced with permission from Sexual Health in Plymouth - SHiP), as it gives you all the information you need about the implant.
