If it is true that a woman's pelvis adjusts over time - expanding during childbearing years, and contracting during menopause - would that imply that a transguy's hips may get smaller over time on T?

I didn't realise this happens. Although I wondered why it's said that female puberty takes 10 yrs and male puberty only 5; so this would explain it. I doubt that your hips will become smaller on T. It would make sense that they'll stop growing wider and just stay the same; as T can't reverse bone growth. A trans man wouldn't have a menopause due to them no longer having periods as well.
On the plus side 5 years of fat redistribution due to T should make your hips look almost non existant.

I don't think the bone/base structure of my hips has changed and I don't anticipate that it would. I have had enough fat redistribution that it may appear as though that is the case, but it's all just been fat moving around.

Fat distribution, yes. Bone structure, nope.

Fwiw, I'm now wondering the same things you are. I would expect this post menopausal shrinking is not the same magnitude as the widening, because pelvis' were traditionally used to sex skeletons before they could use DNA.

Somehow this article makes no sense to me. At first it says that maybe wider hips don't mean that a woman has a harder time walking/running as has always been the assumption. But then at the end it says that it's hypothesized that after 40 womens' hip bones contract again to stabilize the pelvic floor to allow for easier walking.   

I would suspect that if women's hip bones contract when they hit menopause then the same might happen to FTMs on testosterone with low levels of estrogen. However, this is probably not very noticeable on the level of how your body looks and feels. I think fat redistribution combined with added upper body musculature has a much bigger impact on creating a male body type..

The only time I know that a biological females hips change aside from puberty is during pregnancy and when they become sexually active. My hips got  wider once I had started having sex. Of course,  I don't know if being on T at a young age would affect that. My hips haven't shrunk at all. Fat redistribution happens but changes in bone structure don't.

I noticed this as well. In other words, typical bad science journalism.

Personal anecdata is not science. Some women's pelvic angle changes according to a genetic clock between late puberty and early adulthood. Others won't see it change until pregnancy. It has nothing to do with becoming sexually active. T at a young age would almost certainly prevent it.

The angle doesn't change during the onset of puberty, otherwise you would be able to sex teenagers' skeletons that way. The length of arms and legs are being set during that time, however.

Pelvic none structure begins changing at puberty. That's why girls develop hips. I wasn't claiming to have scientific proof of everything causes hips to change. I simply said I don't know what T will do to someone who is still growing. As for sexual activity leading to wider hips, I'll leave that alone. My aunt is a gynecologist and I was going by what she told me.

As I said, I wasn't offering scientific proof. But has been proven that hrt won't make your bone structure change. We wouldn't have the physical aspects we disliked after years on hrt (my hips, for example) if hormones could change our bones.
