ok correct me but i have noticed bone growth with my pelvis ! ok so yea i ain't a early teen more to the end so yea but yea i never measured but i can see it widening i mean i have always had visible hips so i can tell and then i asked my endo and he says his coworkers have told him of patients like me so i say medical studies are not complete

Once you completed your puberty your bones are pretty much set in place for the most part.

You could still be going through puberty thinking that you finished it. If not, def talk to your doctor and make sure he does measurements or other tests because it may be something entirely different.

well possible but i think its because my puberty didn't get to finish and is now just got a new to do list but i can see my hips a lot easier now they bulge a lot more and i haven't got fat there yet

full development in a person who is 46XY might go till early 20's. If you have started HRT before that can be very possible that you go through physical changes associated to 46XX, including wider hips

I voice agains't the crowd that says there is no bone change due to HRT after 20. There is no evidence currently that favor it, and if you think about bone growth you can conclude there are no changes.

This doesn't means there can't be changes.

As a example, I have read medical studies that point the onset of breast development to begin in between 3-6 months of HRT. I had mine begin to develop (painful buds) within 2 weeks of HRT. I can't possibly believe this only out of good wishing, because there were painful buds there and my aureola did itch with only 2 weeks of the stuff. They also point to no voice changes, but considering HRT rewires your brain it is possible to have voice changes on them. I know my voice changed drastically, not in pitch range but in the pitch it settles at and in the manner I speak.

AFAIK there have been no serious clinical trials to identify the bone changes we go under with HRT, there is just an assumption (based on the opinion of specialists, but that still is an assumption) there can't be bone changes after they are locked. There is a very strong basis for this assertion, but it has not been properly demonstrated.

The studies that identify even the ethiology of gender dysphoria are just beginning to clearly define what makes us, us, so I'd say it is fairly early for any sort of truth. Myself, I am glad my hands ARE smaller and my hips seen fuller, if there is some bone change, it is fine, if it is mostly due to muscle loss/fat gain, great too.

  I agree with bird, there isn't enough solid evidence that bone growth cannot be altered after 20 years of age. According to my endo and my GP the average male goes through puberty up intill around age 25 and it's around that time that the growth plates completely fuse together so it's def possible to see bone structure change up into your mid 20's.

My hip bones extend further outward than they did when I started HRT, and they seem to be continuing to 'grow'. I suspect this is caused by a shift in hip position rather than bone growth though, although my cheek bones are cleary growing and have been for the last few months which pretty much goes against everything I thought would happen.

I started HRT at 29 and am 30 now.
