Under normal circumstances, pregnancy occurs when an ovum, or egg cell, released by a woman's ovary during ovulation is fertilized as it passes through the fallopian tube, successfully penetrated by just a single sperm that has traveled through the uterus. After the fertilized egg undergoes a number of cell divisions, the tiny clump of cells enters the uterus, where it burrows into the wall and develops for nine months or so until birth...
...bypass Lesley Brown's fallopian tubes, Oldham Hospital's Steptoe, 65, a highly respected gynecologist, and his colleague, Cambridge University Physiologist Robert Edwards, 52, undertook a remarkable procedure they have been experimenting with for a decade. They removed a ripe egg from Mrs. Brown's ovary, placed it in a laboratory dish and added sperm from her husband. After incubating the ovum as it began to divide, they finally placed the developing embryo in the uterus, where it became implanted and continued to grow into a fetus in what seemed to be an entirely normal...
There was also widespread criticism of the secrecy in which the work of Steptoe and Edwards was conducted. The Uni versity of Pennsylvania's Dr. Luigi Mastroianni, who has him self fertilized eggs in vitro but never attempted to implant them, points out that the British researchers had not provided any details about the condition of Mrs. Brown's fallopian tubes. "If they are completely absent," said Mastroianni, "you must accept the fact that the egg was fertilized in vitro. But if they are just damaged, there's always the possibility that the egg may actually have been fertilized...
...going to be popping out like peanuts." Rather the concern centers on the far-ranging social, ethical and legal repercussions. In the words of Nobel Laureate James Watson, there is the potential for "all sorts of bad scenarios." What, for instance, could prevent a scientist from taking a fertilized egg from one woman, who perhaps did not want to carry her own baby, and implanting it in the womb of a surrogate. Who then would be the child's legal mother? Or, in the words of an old joke, "Which one gets the Mother's Day card...
...brought by a Fort Lauderdale, Fla., dentist, Dr. John Del Zio, 59, and his wife Doris, 34. Despite several operations, Mrs. Del Zio had apparently been unable to become pregnant because of tubal problems. In 1972, she agreed to let Dr. Landrum Shettles place in her womb an egg said to have been fertilized externally by her husband's sperm. But upon learning of the experiment in his department, Vande Wiele destroyed the specimen, contending that the procedure was risky, that Shettles lacked the skills to undertake it and that it had not been approved by the hospital's committee...
