Ancient medical thought: Hippocrates and Aristotle on hair and reproduction

Hippocrates: women's bodies were more porous/sponge-like, including hair and glands, which aided suction of reproductive fluids during intercourse. Aristotle: reproductive fluid made in brain, travels through body; hair follicles impede the journey. Men with long hair = less fertile (hair soaks up fluid). Women with long hair = more fertile (hair aids upward suction). But this function was not unique to hair -- the entire woman's body was seen as spongy. Hair didn't function 'as a testicle' specifically; both men's and women's hair had similar functions with opposite implications.
