...technique for preserving the excised ovary alive and actively developing; passed on to a consideration of optimum temperature, salinity, viscosity ... actually showed them ... how the eggs ... were inspected for abnormalities, counted and transferred to a porous receptacle; how ... this receptacle was immersed in a warm bouillion containing free-swimming spermatozoa...
...average of 14 days before the expected onset of menstruation. Her ovaries then expel one or more egg cells, ripe for fertilization. An individual egg (ovum) is drawn into the fallopian tube (oviduct) to begin a four-day journey toward the uterus. After intercourse, the husband's spermatozoa swim upstream through the uterus into the fallopian tubes, and if one sperm succeeds in penetrating an ovum, conception has occurred. The conceptus, repeatedly doubling the number of its cells, enters the uterus and imbeds itself in the lining for the remainder of the nine months' gestation...
Some biologists believe that humanity begins at conception because the fertilized egg cell contains human DNA (deoxyribonucleic acid). Manhattan Lawyer Cyril Means Jr., among others, finds this line of reasoning unconvincing: each sperm and egg also contain DNA, yet hardly anyone would argue, even metaphysically, that spermatozoa and ova possess the value of human beings...
...ovaries toward the uterus−are hidden in the pelvic cavity of the lower abdomen. Before recent technical advances they were relatively difficult for the surgeon to reach. In the man, a tube called the vas deferens (literally, the "carrying-away vessel") arises from each testicle to carry the spermatozoa to the prostate gland where the seminal fluid is finally compounded for ejaculation through the urethra. Near its origin in the scrotum, the vas deferens is readily accessible to the surgeon's scalpel...
...raft or over Niagara Falls in a barrel. Ordinarily, too, the ovum travels singly, like Lewis or Clark, in the kind of existential loneliness which Norman Mailer usually admires. One might say that the activity of ova involves a daring and independence absent, in fact, from the activity of spermatozoa, which move in jostling masses, swarming out on signal like a crowd of commuters from the 5:15." From this, one can only conclude that women must be the more daring, individualistic and imaginative...
