Thanks for posting your query.
It is in many ways better than oral pills
Its advantages are single application when compared to medications wherein you need to take daily.
You can go for 1 or 2 or 3 or 5 year loops, means they work for so many years based on how many years you need .
You also have a advantage of revival of fertility
by getting it removed at any time in between.
Also very low side effects.
Hope I have answered your query.
Wishing you good health.
