Contraceptive implant: also called subcutaneous implant, subdermal implant or hormonal implant.

The contraceptive implant is a tube or cannula sized piece of plastic that is inserted by a doctor under the skin of the woman. This cannula continuously releases the hormone (progesterone) in the bloodstream to prevent ovulation.

The progesterone released by the contraceptive implant is that which produces the contraceptive effect so that women don’t get pregnant, as it prevents the egg from being released from the ovary. It also causes the uterine lining to become thinner so that in the case of a fertilized egg it cannot be attach to the uterus for lack of space and it also causes the cervical mucus to become thicker thereby forming a plug that blocks sperm.

The subdermal implant insertion is performed during the first days of menstruation, thus ensuring that the woman is not pregnant.

The doctor may insert the contraceptive implant in the inner arm, it is recommended to use another contraceptive during the first 7 days.

The contraceptive implant insertion is painless; usually some local anaesthetic is applied. You may feel a little pressure in the area, both whilst inserting it and to remove it.

It may produce a slight bruise and scar on the area where the implant was inserted but this will heal with time.

- The contraceptive implant tends to produce a slight increase in weight, it can also cause acne or fluid retention.

- May cause local complications where the implant was inserted, because it can cause an infection in the area, this is a rare occurrence.

- Have had or have problems with blood clotting.
