I did one year of medical school many many years ago... and we were taught that the hips and the pelvis on a female and a male are NOT as different as often claimed. It is true that there are those that are different in a lot of cases, but they are impossible to tell apart in a fair number of cases too. I saw on CSI where they made the statement that the pelvis is how they tell the sex of a decomposing body, well that is not always a sure thing, many times we just can't tell the difference. My point being that I think that a lot of trans women will have no trouble baring children once a way to carry them is figured out. C sections will not always be needed...we are all so blended with "sex traits" that I think we forget this.
I read somewhere recently that they can already grow the penis tissue to set off growth of the penis. What they are now trying to do with some consistency is stimulate the growth of the nerves so that the complete penis can be grown with full function. That is a hella good idea to me! The growth of the nerves will allow for the splicing of the nerves that will be needed in cases of trans men and those that need re attachement done etc. They are getting real close to this being completed. So that is some good news too!
Peace,
