CoachThe female system’s organs, all within the lower belly:
- the two ovaries — the gamete stores and factories: unlike the testes, they hold their stock of future egg cells from birth, and from puberty release them one at a time;
- the two oviducts, fringed tubes that catch the released egg cell — the usual meeting place of Proposition 54.2’s step 2;
- the uterus (the womb of Proposition 32.1), whose thick muscular wall and renewable lining are the zygote’s lodging;
- the vagina, connecting the uterus to the outside — where semen is received, and the birth canal of Example 32.6.

Example 57.4 (The egg cell, up close)
The egg cell is the sperm’s opposite in everything but role: the body’s largest cell — a tenth of a millimetre, at the eye’s edge — round, unmoving, stocked with provisions for the journey’s first days (the yolk principle of Remark 8.3, at cell scale). One factory runs continuous millions; the other releases a single provisioned cell a month: Proposition 23.7’s numbers-against-care, written into the gametes themselves.
