It makes sense, but I never asked or was told this

    How do people not know estrogen makes boobs? 😭 /s

    I totally get it. This isn't something the average person has to worry about in the slightest, so I get that it might be a shock or news to them.

    Just know that sex hormones, like during puberty, have certain effects on people's bodies. And for the most part, those effects manifest when trans people take HRT later in life, post puberty.
    Mainly breast growth, skin and fat changes on estrogen and facial hair growth, body hair growth, muscle mass increase and also fat changes for testosterone.

    Who asked me about this? Nobody. I'm really sorry, this is my hyperfixation 😭

    I didn’t mean that in a “why would you tell me this?!?” way, truly in a “I never thought about that, that is neat!” Way

    I just simply never thought about it

    Also Catholic school made me think milk came from pregnancy. It wasn’t a great education.

    Also, another fun fact;

    All people have estrogen and testosterone. The rates just differ (and there's variation too in what that affects more).

    Puberty is triggered by a certain amount of fat reserves being present, due to estrogen and testosterone being made from cholesterol.

    If estrogen dominates, fat is burnt slower, breasts develop and hips get wider, while hair is preserved and doesn't grow thicker.

    With testosterone dominance, more body hair develops (but for some, head hair may fall out later), the vocal cords descend, and the body generally burns fat more quickly in exchange for more (visible) muscle.

    Some people have it inbetween, whether through HRT or naturally (eg. some intersex people). Same with body parts.
