Hi Micky,
I haven't had a hysterectomy and I don't take HRT so can't comment on those aspects of your query. (I have had my ovaries and fallopian tubes removed laparoscopically and, for me, the procedure and recovery were an absolute piece of cake, so I hope that's also the case for you should you go this route).
Maybe I can help with a few general points about hospital consultations...
It sounds like you're due to go back for a hospital appointment fairly soon and that you still have a lot of discuss with the specialist. I always go armed with a list of questions and take someone with me who also has a copy of the same list of questions. That way I can concentrate on asking the questions and asking follow-up questions depending on the answers, my companion can write down the answers and prompt me if I forget or miss anything. On several occasions it has been very helpful to refer back to the written record later. Would this strategy be worth considering?
I agree with Dancinggirl, I don't think the gender of the specialist makes any difference. OK, so men don't have ovaries or a womb or functioning breasts but I've seen male and female gynae specialists, male and female breast specialists - they're all different, some are more knowledgeable and have better communication skills than others. It seems you felt that the gynae you saw was not as informative as you'd hoped? Perhaps next time around, if you arm yourself with the information you're gleaning here (and elsewhere?) and some questions you may find that he is more forthcoming? Alternatively, would you feel able to inform the hospital that you wish to see someone else? (You have the choice, something that patients often forget).
Please don't be hurried at consultations. I don't know what the nominal allocated time is for a specialist consultation at my local NHS trust and, frankly, I don't care. I take as long as I need - sometimes this is a few minutes, sometimes it is much much longer. I have NEVER experienced any problems with taking the time I need in a consultation and have found that most consultants react well to a well-informed, empowered, inquisitive patient.
It sounds like you are gathering information to make a reasoned decision on the best way forward for you. I wish you luck with this.
