It's very possible, humans are not as sexually dimorphic as many other mammals. Hormones control and influence a lot and we are only getting better at changing people's phenotype. The shape of people's bodies, our sex characteristics, the hormones we run on, that's all biology, all changeable to a growing extent.

If humans are not as sexually dimorphic as many other mammals, how come that even amongst those in trans community who have gone to the greatest lengths using Big Pharma hormone formulations (and sometimes surgeries) to alter their outward appearance to give the impression they have secondary sex characteristics of the opposite sex, only TPs who are biologically female get pregnant and have babies?

If humans are not as sexually dimorphic as many other mammals, how come that even amongst those in trans community who have gone to the greatest lengths using Big Pharma hormone formulations (and sometimes surgeries) to alter their outward appearance to give the impression they have secondary sex characteristics of the opposite sex, how come male TPs are winning and setting records in girls' and women's sports but female TPs are not winning and setting records in boys' and men's sports? How come male TPs are bumping girls and women off teams, out of competition, off awards podiums and out of record books - but not a single female TP has done the same to any boys or men? How come numerous male TPs have taken top place and won titles and trophies in women's and girls' sports, but no female TPs have managed to distinguish themselves similarly in men's and boys' sports. Is it because trans boys and trans men don't try as hard as trans girls and trans women?

Yes, some fat can be redistributed, but there is no way to make a male skeleton into a female on, or vice versa. There is no way to change male kidneys into female kidneys. Males who suppress T and take estradiol still have hearts and lungs that are 25-38% and 10-12% larger and more powerful respectively than female people of equivalent height, weight and age - and male twitch fibers, male tendons, male airway cells, male explosiveness. Females who take exogenous testosterone will get deeper voices, facial hair, male-pattern balding and much higher rates of CV disease - but they still will have female pelvises, and thus female Q angles; female hearts, lungs, hands and feet and all the rest.

Also, you don't seem to understand the difference between primary and secondary sex characteristics. Or between outwardly appearing to be something and actually being it. Used to be, learning about Potemkin villages, animals changing coloration, trompe-l'œil, subterfuge, FX in media were standard parts of growing up. Used to be, most people grew up to understand that surface is not substance, illusion and reality are not the same thing, and there's often a major difference between the outer packaging and what's inside. Did you really reach adulthood not learning any of this?
