Now, there is some context here to be considered.
The woman's daughter transitioned at the age of 3, and has not and will not, apparently, go through male puberty. Regardless of my mixed feelings about transitioning that early, I think that is quite different than someone who has transitioned at a later age.
Unfortunately, I don't really see either side addressing the differences between a pre-pubescent vs. post-pubescent transition.
And that's a bit of a shame.
Yeah, definitely a shame. At 9 years old, there are some differences in overall height and size, but third grade isn't particularly "competitive" in school.
Prepubescent I don't care, let anyone play however they want, as long as everyone behaves.
Once puberty hits, it becomes a different story though. Even if this specific child is given testosterone suppressors and estrogen as soon as puberty triggers... they are still likely to be taller and stronger than females will be. Height is governed largely by the adrenal gland, not the pituitary. The adrenal causes the long bones to extend and to accrete density, as well as the closure of growth plates. It also causes the development of fine leg, armpit, and pubic hair. The pituitary causes the hormonal shifts that create sexual maturity, including the development of secondary sexual characteristics. That includes facial hair, body hair, and dense leg and arm hair in males, as well as thickening of the underarm and pubic hair in both sexes.
Cross sex hormones won't change how the adrenal operates. A male child will still grow to male height during puberty if given cross-sex hormones.
Additionally, neither the adrenal nor the pituitary will alter the physiological differences between from skeletal and internal organ differences. Males will still be able to take longer strides, they'll still have male attachment points for the tendons in their arms and legs which effects the mass that can be lifted even aside from muscle density. And they'll still have larger lung capacity, and abdominal organs not positioned around a uterus.
