All about the pelvis
« on: February 16, 2013, 10:40:31 pm »
Hi everyone;
I Would like to find out a few things about the pelvic bone, primarily in relation to MTF hormone therapy;

1) What is the process by which a girl's pelvis widens during puberty?
2) How can the pelvis grow in one direction (width) If the periosteum covers the entire bone?
3) Does the shape of the male pelvis physically prevent it from widening (i.e., would surgery be required to aid in hormone-based pelvic widening)
4) Considering that the pelvis is not a long bone, does it still have epiphyseal plates. If not, then is the pelvis affected by epiphyseal closure during the late teenage years.
5) A study was done showing that the pelvic bone continues to widen by a small amount after skeletal maturity (Link Here). Do you think this could be exploited by MTFs to help with pelvic widening (note that the actual bone only widens about 1 inch over the course of 50 odd years)

If you know anything else about the pelvis or bones in general (pertaining to transgendered persons) then please feel free to add on anything that was not mentioned above in your post.

Thanks,
Thanata

Actually the pelvis is composed of several bones: the sacrum and coccyx (which are part of you axia skeleton) and the the three proper pelvic bones the Ischium, ileum and pubis. The ileum sichium and pubis are separated during childhood but fuse during puberty. A surge of estrogen during puberty closes the epiphesial plates of all bone in the female.

The shape of the human pelvis is sexually dimorphic, the female is wider by bone configuration rather than by "growth."  The so called "widening" of the female pelvis during late puberty is mostly due to an increase in subcutaneous fat.

For most MTF HRT results of an increase in subcutaneous fat around the hip...but no, no hope to increase the bone to make any significant difference. Rather, loss of mass in the upper torso together with the growth of breast tends to make the MTF shape more feminine. Choice of appropriate colors and style of clothing, as well as posture are a plus

Hope this helps

So is it almost impossible to get those child-bearing hips during HRT transition?

Well mine did, I have "child bearing hips" but then again I never had the pelvis of a guy per say, pre-hrt.  At about 4 months my hips were getting wider. I remember sitting and my legs facing inwards. I looked at my friend sitting next to me and had to do a double take (we were sitting by a lake in the sand) I couldn't believe it! My legs were positioned exactly like hers. I'm at about 11 months and the fat is distributing to the proper areas. I've gone from a 34" to about 38" currently in my hips.

 Well, I used to be 30" and now I'm 33" or so. Started hormones at seventeen... and there's not much fat down there, since I'm skeleton-skinny.

 I didn't really notice them changing much, but one day I started fitting into pants that used to be really loose in the hips, so maybe there's progress. Size zeros just aren't working for me any more. :)

 It's only anecdotal, and I don't even know how accurate my measurements are and were, but I believe that hormones can change hip width if you're young enough, and I think I experienced a little bit of that.

How would this affect pre-puberty transitioners (with puberty blockers)?

If you are XY-person on T blockers and no estrogen then your bones will remain child-like with soem agenderless growth

If you are XY-person on T-blockers alone and estrogen your growth will stop and your pelvis will turn more female like

Like some of the others, I did get much wider hips after HRT.  However I did have large hips before aswell.  As my ex use to make comment about when she was angry with me; unknown to her I actually loved it when she pointed out I had womanly hips  >:-)  But after HRT they have definitely swung out and I have a very good hip to waist ratio.  I think it's another one of them things were you could get lucky when you start HRT.

for those with very masculine and narrow hips/pelvis, is there possibly a way to begin to develop a way to modify and/or replace one's pelvis ?

Started HRT on March 16th, 2016  ;D
