Merina IUD vs. Orthia Tricyclin: Understanding Hormone Levels and Pregnancy Prevention

Question
tell me the hormon level difference in the merina IUD and the Ortha tricyclin low!

Answer
I don't know anything about the hormone levels in IUDs. What I do know about the IUD is that is prevents implantation of a fertilized egg, which is a conception, which means that it is an early abortion.  

No one knows how many of these early abortions occur but life begins at conception so it is definitely the wrong approach to avoiding pregnancy.  Sorry I could not be more helpful.
