The contraceptive implant is a thin, flexible, plastic rod (4cm x 2mm) containing a Progestogen hormone. It is inserted, after local anaesthetic, under the skin of the inner upper arm by a Doctor. The procedure takes only a few minutes.
The implant prevents pregnancy by releasing small but constant amounts of the hormone into the body via the bloodstream. Specifically, this prevents pregnancy by blocking ovulation (the release of eggs from the ovaries). It also thickens the mucus at the cervix so that so that sperm cannot get through to meet an egg.
Contraceptive implants are 99.9 percent effective – that is, if 1,000 women used it for a year, only one of them might become pregnant. It is more reliable than the contraceptive pill as there is no need for you to remember to take a pill every day. Please remember that no contraceptive is ever 100 percent effective.
This form of contraceptive lasts for 3 years and is very easily reversible. An Implanon can easily be removed at any time by the Doctor. When having an Implanon removed, fertility returns back to normal, with most women ovulating within the first month after the removal.
Please be aware that the implant does not protect against contracting sexually transmitted infections (STIs) or HIV/AIDS.
