Pinto-Correia focuses not on the debate between epigenesis (the ultimately prevalent theory) and preformation (what she calls the "beautiful loser"), but on the battle between the contesting factions within preformation: ovism and spermism.
Pinto-Correia employs her enormous literary and linguistic erudition to illustrate how the general prejudices against the term homunculus associated with spermism ultimately contributed to its dismissal; how ovism was automatically bolstered by the spherical nature of an egg, a universal symbol of generation (like the Earth, the Sun, and the chicken egg); and how ovism was nonetheless prejudiced for ascribing, in a patriarchal society, the chief role in generation to an egg found only in women.
Had they done so, Pinto-Correia speculates, spermism, might have remained a viable theory longer.
