Some like me even add some T post-op to help with skin, energy levels, libido, muscle mass as the adrenals produce very little T. I noticed my skin getting softer and more elastic (bouncy) after adding the T.

Skin is also much less dry, heals better, is thicker and stronger.
Post-op transwomen and ciswomen who have their ovaries removed have typically less T than premenopausal (and even some post-menopausal) ciswomen who keep their ovaries.
