biological insights to heal our psychic wounds, understand our fears, and make the most of what we have and of those who will have us and love us. It's a superb phrase. We need liberation, perpetual revolution. What better place to begin the insurrection than at the doors to the palace we've lived in all these years?

Unscrambling the Egg: It Begins with One Perfect Solar Cell
Put a few adults in a room with a sweet-tempered infant, and you may as well leave a tub of butter sitting out in the midday sun. Within moments of crowding around the crib, their grown-up bones begin to soften and their spines to bend. Their eyes mist over with cataracts of pleasure. They misplace intellect and discover new vocal ranges countertenor, soprano, piglet. And when they happen on the baby's hands, prepare for a variant on the ancient Ode to the Fingernail. Nothing so focuses adult adoration as a newborn's fingernail, its lovely condensed precocity. See the tiny cuticle below, the white eyebrow of keratin on top, the curved buff of the nail body, the irresistible businesslike quality of the whole: it looks like it really works! We love the infant fingernail for its capacity to flatter, its miniature yet faithful recreation of our own form. More than in the thigh or the eye or even the springy nautilus shell of the ear, in the baby's nail sits the homunculus, the adult in preview. And so, we are reminded, the future is assured.
Myself, I prefer eggs.
At some point midway through my pregnancy, when I knew I was carrying a daughter, I began to think of myself as standing in a room with two facing mirrors, so that looking into one mirror you see the other mirror reflecting it, and you, off into something approaching an infinity of images. At twenty weeks' gestation, my girl held within her nine-ounce, banana-sized body, in a position spatially equivalent to where she floated in me, the tangled grapevines of my genomic future. Halfway through her fetal tenure, she already had all the eggs she would ever have, packed into ovaries no bigger than the letters
ova
you just passed. My daughter's eggs are silver points of potential energy, the

light at the beginning of the tunnel, a near-life experience. Boys don't make sperm their proud "seed" until they reach puberty. But my daughter's sex cells,
our
seed, are already settled upon prenatally, the chromosomes sorted, the potsherds of her parents' histories packed into their little phospholipid baggies.
The image of the nested Russian dolls is used too often. I see it everywhere, particularly in descriptions of scientific mysteries (you open one mystery, you encounter another). But if there were ever an appropriate time to dust off the simile, it's here, to describe the nested nature of the matriline. Consider, if you will, the ovoid shape of the doll and the compelling unpredictability and fluidity of dynasty. Open the ovoid mother and find the ovoid girl; open the child and the next egg grins up its invitation to crack it. You can never tell a priori how many iterations await you; you hope they continue forever. My daughter, my matryoshka.
I said a moment ago that my daughter had all her eggs in mid-fetushood. In fact she was goosed up way beyond capacity, a fatly subsidized poultry farm. She had all her eggs and many more, and she will lose the great majority of those glittering germ cells before she begins to menstruate. At twenty weeks' gestation, the peak of a female's oogonial load, the fetus holds 6 to 7 million eggs. In the next twenty weeks of wombing, 4 million of those eggs will die, and by puberty all but 400,000 will have taken to the wing, without a squabble, without a peep.
The attrition continues, though at a more sedate pace, throughout a woman's youth and early middle age. At most, 450 of her eggs will be solicited for ovulation, and far fewer than that if she spends a lot of time being pregnant and thus not ovulating. Yet by menopause, few if any eggs remain in the ovaries. The rest have vanished. The body has reclaimed them.
This is a basic principle of living organisms. Life is profligate; life is a spendthrift; life can persist only by living beyond its means. You make things in extravagant abundance, and then you shave back, throw away, kill off the excess. Through extensive cell death the brain is molded, transformed from a teeming pudding of primitive, overpopulous neurons into an organized structure of convolutions and connections, recognizable lobes and nuclei; by the time the human brain has finished

developing, in infancy, 90 percent of its original cell number has died, leaving the privileged few to sustain the hard work of dwelling on mortality. This is also how limbs are built. At some point in embryogenesis, the fingers and toes must be relieved of their interdigital webbing, or we would emerge from our amniotic aquarium with flippers and fins. And this too is how the future is laid down.
The millions of eggs that we women begin with are cleanly destroyed through an innate cell program called apoptosis. The eggs do not simply die they commit suicide. Their membranes ruffle up like petticoats whipped by the wind and they break into pieces, thence to be absorbed bit by bit into the hearts of neighboring cells. By graciously if melodramatically getting out of the way, the sacrificial eggs leave their sisters plenty of hatching room. I love the word
apoptosis
, the onomatopoeia of it:
a-POP-tosis
. The eggs pop apart like poked soap bubbles, a brief flash of taut, refracted light and then, ka-
ping!
And while my girl grew toward completion inside me, her fresh little eggs popped by the tens of thousands each day. By the time she is born, I thought, her eggs will be the rarest cells in her body.
Scientists have made much of apoptosis in the past few years. They have sought to link every disease known to granting agencies, whether cancer, Alzheimer's, or AIDS, to a breakdown in the body's ability to control when pieces of itself must die. Just as a pregnant woman sees nothing but a sea of swollen bellies all around her, so scientists see apoptosis gone awry in every ill person or sickly white mouse they examine, and they promise grand paybacks in cures and amelioratives if they ever master apoptosis. For our purposes, let us think not of disease or dysfunction; let us instead praise the dying hordes, and lubricate their departure with tears of gratitude. Yes, it's wasteful, yes, it seems stupid to make so much and then immediately destroy nearly all of it, but would nature get anywhere if she were stingy? Would we expect to see her flagrant diversity, her blowsy sequins and feather boas, if she weren't simply and reliably
too much?
Think of it this way: without the unchosen, there can be no choosing. Unless we break eggs, there can be no soufflé. The eggs that survive the streamlining process could well be the tastiest ones in the nest.
And so, from an eggy perspective, we may not be such random, sorry creatures after all, such products of contingency or freak odds as many

of us glumly decided during our days of adolescent sky-punching (Why me, oh Lord? How did that outrageous accident happen?). The chances of any of us being, rather than not being, may not be so outrageous, considering how much was winnowed out before we ever arrived at the possibility of being. I used to wonder why life works as well as it does, why humans and other animals generally emerge from incubation in such beautiful condition why there aren't more developmental horrors. We all know about the high rate of spontaneous miscarriages during the first trimester of pregnancy, and we have all heard that the majority of those miscarriages are blessed expulsions, eliminating embryos with chromosomes too distorted for being. Yet long before that point, when imperfect egg has met bad sperm, came the vast sweeps of the apoptotic broom, the vigorous judgment of no, no, no. Not you, not you, and most definitely not you. Through cell suicide, we at last get to yes a rare word, but beautiful in its rarity.
We are all yeses. We are worthy enough, we passed inspection, we survived the great fetal oocyte extinctions. In that sense, at least call it a mechanospiritual sense we are meant to be. We are good eggs, every one of us.
If you have never had trouble with your eggs, if you have never had to worry about your fecundity, you probably haven't given your eggs much thought, or dwelled on their dimensions, the particular power that egg cells enclose. You think of eggs, you think food: poached, scrambled, or forbidden. Or maybe you were lucky enough as a child to find in your back yard a nest with two or three robin's eggs inside, each looking so tender and pale that you held your breath before venturing to touch one. I was unhappily familiar in my girlhood with another sort of animal egg, that of a cockroach; usually I found the empty egg case after its cargo had safely departed, a sight as disturbing as that of a spent shotgun shell and more evidence of the insect's supremacy.
The symbolic impact of the egg in many cultures is as an oval. The egg of the world, thick toward the bottom to ground us, thinner at the apex as though pointing toward the heavens. In medieval paintings and cathedral tympana, Christus Regnans sits in a heavenly ovoid: he who gave birth to the world was born unto the world to secure it from death. At Easter we paint eggs to celebrate rebirth, resurrection; in the egg is

life, as life is cradled in the cupped, ovoid palms of the hands. The Hindu gods Ganesha and Shiva Nataraja sit or dance in egg-shaped, flame-tipped backdrops. In painting her vulval flowers, the petals opening onto other petals like abstract pastel matryoshkas, Georgia O'Keeffe evoked as well the image of the egg, as though female genitalia recapitulate female procreative powers.
The egg of a chicken or other bird is a triumph in packaging. A female bird makes the bulk of the egg inside her reproductive tract long before mating with a male. She supplies the egg with all the nutrients the chick embryo will require to reach pecking independence. The reason that an egg yolk is so rich in cholesterol, and thus that people see it as gastronomically risqué, is that a growing fetus needs ample cholesterol to build the membranes of the cells of which the body, any body, is constructed. The bird gives the egg protein, sugars, hormones, growth factors. Only after the cupboards are fully stocked will the egg be fertilized by sperm, sealed with a few calciferous layers of eggshell, and finally laid. Bird eggs are usually oval, in part for aerodynamic reasons: the shape makes their odyssey down the cloaca, the bird's equivalent of a birth canal, that much smoother.
We gals have been called chicks, and in Britain we've been birds, but if our eggs are any indication, the comparison is daft. A woman's egg, like that of any other mammal, has nothing avian about it. There is no shell, of course, and there really is no yolk, although the aqueous body of the egg, the cytoplasm, would feel a bit yolky to the touch if it were big enough to stick your finger in. But a human egg has no food with which to feed an embryo. And though one springs to fullness upon ovulation each month, it most certainly is not the pit-faced, frigid moon.
I have another suggestion. Let's reject the notion that men have exclusive rights to the sun. Must Helios, Apollo, Ra, Mithras, and the other golden boys take up every seat in the solar chariot that lights each day and coaxes forth all life? This is a miscarriage of mythology, for a woman's egg resembles nothing so much as the sun at its most electrically alive: the perfect orb, speaking in tongues of fire.
Dr. Maria Bustillo is a short, barrel-bodied woman in her mid-forties who frequently smiles small, private smiles, as though life dependably

amuses her. She is a Cuban American. Her features are round but not pudgy, and she wears her dark hair neither short nor long. As an infertility expert, Bustillo is a modern Demeter, a harvester and deft manipulator of human eggs, a magician in a minor key. She helps some couples who are desperate for parenthood get pregnant, and to them she is a goddess. But others she cannot help. For those others, it is no metaphor to say they flush many thousands of dollars down the toilet with each cycle of IVF or GIFT or other prayers by alphabet.

That is the reality of infertility treatment today, as we have read and heard and read again: it is very expensive, and it often fails. Nevertheless, Bustillo smiles her small amused smiles and does not coddle gloom. She manages to seem simultaneously brisk and easygoing. Her staff loves working with her; her patients appreciate her candor and her refusal to condescend. I liked her instantly and almost without qualification. Only once did she say something that reminded me, oh, yes, she is a surgeon, a wisecracking cowgirl in scrubs. As she washed her hands before performing a vaginal procedure, she repeated a smirking remark that she'd heard from one of her instructors years earlier. ''He told me, 'Washing your hands before doing vaginal surgery is like taking a shower before taking a crap,'" Bustillo said. The vagina is quite dirty, she continued, so there is nothing you could introduce into it with your hands that would be worse than what's already there. (This bit of orificial wisdom, by the way, is an old husbands' tale, a load of crap, as we will discuss in Chapter 4. The vagina is not dirty at all. Really, is it too much for us who mount the gynecologist's unholy stirrups to ask, "Physician, clean thyself"?)
I am visiting Bustillo at the Mount Sinai School of Medicine in New York to look at eggs. I have seen the eggs of many species, but I have never seen the eggs of my own kind, except in pictures. Seeing a human egg is not easy. It is the largest cell in the body, but it is nonetheless very small, a tenth of a millimeter across. If you could poke a hole in a piece of paper with a baby's hair, you'd get something the size of an egg. Moreover, an egg isn't
meant
to be seen. The human egg, like any

IVF means in vitro ("in glass") fertilization, as opposed to in vivo ("in body"), the old-fashioned way. GIFT, or gamete intrafallopian transfer, is a variant on IVF in which eggs and sperm are injected into a woman's fallopian tube, with the hope that they will find each other and create a zygote.
