What is the contraceptive chip and how does it work?

Nowadays, most women choose to plan their motherhood or avoid a possible unwanted pregnancy. And that’s why they turn to different contraceptive methods.

One of the most used devices in recent times, thanks to its practicality and effectiveness, is the contraceptive chip. Easy to access and position, this “chip” is implanted in the arm and prevents pregnancies for up to three years, offering greater than 99% protection.

“It is a safe, reversible and ultra-effective method, with less than 0.2% failures“explains Dr. María Elisa Molteni, of the Argentine Medical Association of Contraception (AMAdA).

What is the contraceptive chip and how does it work?

The contraceptive chip is a flexible rod that it is placed subcutaneously on the woman’s arm. It is a very simple procedure, performed by healthcare professionals, and with local anesthesia. Furthermore, it is completely reversible: fertility returns as soon as it is removed.

“It contains etonogestrel, a derivative of progesterone. This hormone is released in low doses and regularly, which thickens the lining of the cervix and thins its lining. Once the contraceptive chip is inserted, the drug begins to be released, inhibiting ovulation”, explains Dr. Molteni.

The AMAdA specialist adds that “using this subcutaneous device the menstrual cycle stops regular, a completely normal effect after placement.”
