...many scientists, there were even more sweeping ramifications. They noted that in-vitro fertilization techniques may give researchers an important new laboratory tool for devising ways of coping with genetic diseases, testing new methods of contraception and, perhaps most important of all, studying close up one of nature's most awesome and still baffling processes: the first stirrings of life. Said one leading specialist on reproductive physiology, Dr. Carl Pauerstein of the University of Texas, of the British work: "It has the potential for adding greatly to the knowledge of the reproductive biology of our species...
Other researchers were far more skeptical of going beyond in-vitro fertilization to the actual implantation of the developing embryo in the uterus. "The potential for misadventure is unlimited," said Dr. John Marshall, head of obstetrics and gynecology at Los Angeles County's Harbor General Hospital. How sure could anyone be that the Browns' baby will not be deformed, he asked. "What if we got an otherwise perfectly formed individual that was a cyclops? Who is responsible? The parents? The doctor? Is the government obligated to take care...
...before the tubal problems), damaged her both physically and psychologically, upset her sex life and jeopardized her marriage. The defense, for its part, questions whether the flamboyant Shettles, who has since left the hospital, ever managed to fertilize Mrs. Del Zio's egg and whether his other claims of in-vitro fertilization were valid. Scornfully, a defense lawyer said Shettles' work was as different from the achievement of Steptoe and Edwards as "a Model T Ford is from a Porsche...
...until the mid-1960s did researchers learn how to fertilize mammalian eggs in vitro on a regular basis. The groundwork was laid by M.C. Chang of the Worcester Foundation for Experimental Biology in Shrewsbury, Mass., and C.R. Austin of Cambridge University, who had solved the problem of in-vitro capacitation of rabbit sperm, a process that enabled sperm to penetrate the egg in the laboratory. Until then, the sperm were notably ineffectual in that role. But these early successes 'involved creatures no higher than rabbits, hamsters and mice...
...repair many tubes with precise microsurgery. But for Mrs. Brown that did not appear possible. The door to pregnancy seemed to be tightly shut until she was referred to Steptoe, who with Edwards had probably made more attempts than any other researchers to get around such blockages by in-vitro fertilization and implanting techniques...
