Hey Dee,
I was recently diagnosed with endo after TTC #2 for 5+ years. My FS said that he didn't think he could remove it as I had white sheets of it instead of the classic chocolate cysts, and he thought he would damage my uterus and ovaries if he tried to remove it. I also had one blocked tube.

I went on Synarel for 3 months before starting on our first IVF cycle a few weeks ago.
Normally the bottle of Synarel is roughly $100, but because I have endo, it is subsidised and I got it for about $30 a bottle. I was sniffing twice a day.

Sorry I can't help you out with the other drug. I'm sure I've read that a few girls on here are or have been using Zoladex.

Maybe getting your Dr to explain all the pros and cons of the Zoladex and any other drugs that he thinks would be ok for you to use.

Sorry I can't be anymore help than that.

Goodluck..

Nic
