...more serious objection: if a woman thinks that she is not pregnant when, in fact, she is, she may delay going to a physician. Such procrastination can be particularly dangerous in tubal pregnancies, which require early medical attention because the fallopian tube can rupture and possibly cause death...
Steptoe revealed that the birth had been filmed; the pictures may prove an important point. Some doctors had observed that if Lesley's fallopian tubes were intact, Steptoe would not have irrefutable proof that Louise was conceived in a test tube. But, Steptoe said with evident satisfaction, "I was able to show that the tubes were absent." Lesley, he explained, had had an operation in 1970 to clear her blocked tubes?but with no success. After she was referred to Steptoe in 1976, he did an exploratory operation and found "there were mere remnants of her tubes." Because these remnants...
...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...
...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 in vivo [in the body] ? that the tubes may have functioned...
...intricate and marvelous. Stimulated by hormones, part of the body's chemical signaling system, a ripe egg is expelled from its grapelike encasement, or follicle, in the ovary; in any month, either of the female's two ovaries may contribute an ovum. Then the egg enters the nearby fallopian tube. If coitus has taken place, the egg will shortly run into a swarm of tailed sperm that have managed, like salmon battling upstream, to fight their way into this passageway. In a dramatic headlong plunge, a single sperm will penetrate the waiting ovum's outer layer, its 23 chromosomes joining...
