A transphobe walks into the doctor and says "gimme some of that estrogen, I wanna play in ladies sports- because I'll crush all of them and win."
the doctor says "okay, the effects of estrogen include- less muscle mass, smaller junk, enlarged breasts, less fertile sp3rm, lower libido, and a higher voice."
the transphobe raises his eyebrow "what?! what kind of man would want all that?!"
the doctor smiles and says "a woman."
