It was never brought up before my hysto a little over a week ago. But then, I'm on Nebido, so "stopping a couple of weeks before" wouldn't be possible anyways. I do have an increased rbc, but again, never mentioned as a problem. I had minimal bleeding and a speedy recovery (thus far, knock on wood).
As for stopping when being post hysto, I doubt the body would take much damage from being without a sex hormone for a limited time only.
As for my increased rbc, I had recently taken a shot when seeing my endo last, and he told me to add a couple of extra weeks between my shots because of the rbc. In my mind I was was like "crap.. hope that doesn't trigger a period... D= " ..and then a week later the hospital calls and say they have an opening and can do my hysto in another two weeks. I kinda felt like I should be playing the lottery then. XD
