Etonogestrel is similar to a natural hormone made in the body, which works by preventing the release of an egg during the menstrual cycle. Etonogestrel also thickens vaginal fluid to help prevent sperm from reaching an egg and changes the lining of the uterus to prevent a fertilized egg from attaching.

Implanon is an effective and popular contraceptive implant today. With just one implant, women can prevent pregnancy for about 3 years without using any other support measures.

With the advantage of only needing 1 implant to prevent pregnancy for 3 years, Implanon is currently a popular contraceptive implant.

Although safe, effective and has many outstanding advantages, the Implanon contraceptive implant cannot be applied to all women. Pregnant women, women who are breastfeeding for less than 6 weeks, have abnormal bleeding, or have breast cancer,... are typical contraindications of the Implanon contraceptive implant.

Women can have the implant inserted at any time if they are certain that they are not pregnant at the time. The best time to have the implant inserted is after their period ends, which is usually within the first 5 days of their first period.

Women can remove the implant whenever they want. After removal, ovulation quickly resumes and fertility returns to normal.
