Transgender: Is it written in my bones?

Somethings I noticed on a recent x-ray

Note: I am not a doctor, nor am I trained to perform any sort of medical analysis. I am just a person with an interest in these types of things, particularly when they affect me.

I recently broke my pelvis and something came as a surprise, but wasn’t necessarily a surprise to me. Wow, you may find that statement a little confusing, so allow me to explain.

You could say that my development as a person was a little odd. And as they were occurring, it played hell with my feelings. You should know that by now that I am transgender. I struggled with gender identity my whole life which eventually led to me transitioning. Later on in life, I have been looking into these anomalies I went through to find the origins/reasons for them. If I found the reason; would it explain why I am the way I am? Who knows….

Recently I posted this picture of my pelvis as part of my story about my pelvic fracture —

Did you notice anything? From a standpoint of sex/gender?

If you didn’t let me point out some things I noticed and explain them in detail that I did not cover in that original story.

The first area we will focus on are these, known as the ischium:

On a male pelvis, they tend to be more circular in nature and loop down more dramatically, while on a female pelvis they are more flatter and oblong shaped. Clearly, mine appear flatter and more oblong.

Next, we have what is known as the pubic arch:

Male arches are quite narrow — typically in 60–70 degree range. Female arches are wider, starting at 80–90 degrees and go up from there. Mine measures at well over 100 degrees. (I measured it at 131 degrees, but not sure how precise that was….)
