In your medical opinion, which synthetic birth control is the safest method, least potential longterm conseq. or damage to endo/ovary feedback loops?

Combined OCs: Combined estrogen and progesterone are typically going to be the best at treating endometriosis, if that's what you are referring to by "endo." Progesterone, by itself, in the form of pills, shot or Mirena (levonorgestrel) IUD is another thought and studies show progesterone alone helps. Most practioners, however, start with an estrogen/progesterone pill They are all very similar. I like Kariva.
