Hi purplebee - if you are having a full hysterectomy ie including cervix then you won't need progesterone even as a trial, for endometrial protection, whereas it is often advised in cases of sub-total hysterectomy where the cervix is retained. As others have said there is nothing to stop you taking progesterone in addition to the oestrogen only patches, provided the doctor will prescribe it. Most of us would prefer to be rid of the devil hormone! You can also be prescribed vaginal oestrogen in addition to systemic oestrogen, if you need it.
And to add that you haven't mentioned your ovaries - whether the medics want to remove them too - but if they are healthy, then I would ask to keep them, even at your age as they do continue to produce some testosterone for some years after menopause - though of course this depends when your menopause was, if you know this.
