Your article on birth control [Jan. 10] goes around Robin Hood's barn for an answer to the birth control problem. Why take chances with pills, vaccines, etc., when a vasectomy in males and tying of fallopian tubes in females ends the problem quickly and finally? N.R. Vance Nashville...
...successful experiment began in Texas in the spring of 1975, when Researchers Duane Kraemer, Gary Moore and Martin Kramen removed a fertilized egg from a baboon five days after she had mated with a male. At that point the egg had moved from her fallopian tube and was floating freely, but it had not yet become implanted in the uterine wall, where there would have been more difficulty in removing it. The fertilized egg was then implanted in the uterine wall of a second female that had been chosen as foster mother because she had ovulated on the same...

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...
