About 15% of all women who want to bear children fail to conceive, many of them because of defects in their fallopian tubes. In England last week there was a flurry of optimism about a successful treatment for some of these would-be mothers. A respected, pioneering obstetrician-gynecologist reported that in three cases a ripe egg cell had been removed from a wife and fertilized in a laboratory by sperm from her husband; then the resulting conceptus had been implanted in the wife's womb and she had given birth to a normal child. The three babies thus...
Normally a woman of childbearing age ovulates once every lunar month, an 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...
Against a dark background, a pinkish ovarian follicle swells until an egg bursts forth and sails along the convoluted lining of the fallopian tube like a miniature moon over a mountain range. Sperm, their tails thrashing, cluster together like salmon awaiting a signal to leap a waterfall. Cells, pulsing with life, divide and reproduce. Finally, in a scene reminiscent of the fadeout of 2001, a fetus, its already human form visible through a transparent amniotic sac, fills the screen. These spectacular images (see following pages) are not the products of a Hollywood special effects department. They are frames from...
...Pipeline. Sterilization operations for men and women are based on the same strategy: cutting the tubes that carry the sex cells on their paths toward junction and conception. In the woman, the Fallopian tubes−through which the egg cells travel from the 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...
...cause cancer in animals. There is no reason," Davis insisted, "to presume that the single exception will turn out to be the oral contraceptives." Neither Nelson nor the only other Senator present, New Hampshire's Thomas J. Mclntyre, caught Davis up on what might be called a Fallopian fallacy: while it is correct to say that everything known to cause cancer in man also causes cancer in animals, the converse is not true...
