How does the contraceptive implant works?

Hormone progesterone found in this implant is slowly released into the blood constant. Progestin mainly stops ovulation (release of egg from the ovary).

Mucus thickens and forms a plug at the cervix. This stops sperm reaching the uterus and fertilize. Uterine mucosa becomes thinner under the action of this progestin. This means that when an egg was fertilized, however, it is very unlikely to attach to the uterus.

Are there any risks?

In rare cases, the implant can cause an infection in the arm shortly after being introduced. Research on risk of breast cancer and hormonal contraception is complex and contradictory. They suggest that women using hormonal contraceptives, it seems, will slightly increase the risk of being diagnosed with breast cancer compared to women not using hormonal contraceptives.

How does the implant affect the menstrual cycle?

- in some women, menstrual periods will stop completely.
- some women experience irregular periods or metrorrhagia (bleeding between menstrual periods).
- in some women, menstrual cycle may increase and / or will be intensified.
- these changes may be a noticeable discomfort, but not dangerous. If you experience prolonged bleeding, your doctor may be able to recommend the use of additional hormone or take a medicine that can help control bleeding. The doctor may also investigate if the bleeding is not the effect of other causes such as infection.
- some drugs, such as HIV or epilepsy or some homeopathic remedies (St. John’s Wort) may reduce the effectiveness of the implant.
