I've been on the pellet implants for a few years. I love them! They deliver a much higher E level than was observed with any of the other methods of administration. Unlike tablets, they do not pass through the liver, but are directly delivered to the bloodstream. They keep the levels very stable which is good for my emotional wellbeing. And they are cheap (at least, in Australia). Best of all, I don't have to remember to take a tablet throughout the day.
I get a new one put in every 6 months, which takes about 20 minutes at the endo's office.
I'm considering moving to the US very soon, and I've heard they are not available there which has me a bit worried.
I'm thinking about whether I can plan trips home to visit the family around visits to the endocrinologist...
I love my 'hip ovaries'. :-)
