Hi Kiltgirl, I had mine removed last year, but for different reasons, had lots of fertility treatment in the past that they now state can potentially lead to ovarian cancer and was having some pain from left ovary, so it was more a preventative action.
My problem was I was not given HRT immediately, as I was supposedly post meno. So had really bad symptoms start off, indicative of no oestrogen, which blood test 2 weeks post confirmed. I started on HRT after 2 weeks and then slowly got back to normal. Found that the transdermal, constant dose oestrogen to be the best (started with femoston tablets, but got bad headaches). So please make sure that you start the HRT as soon as you have had the op, also it may be wise to get a blood test of oestrogen levels before (if you are post meno), if not it will fluctuate anyway. I find I do not need testosterone, my energy levels etc eventually got back to normal (my adrenals must be producing it).
Hope this helps a little.
