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...
...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...
Under normal circumstances, pregnancy occurs when an ovum, or egg cell, released by a woman's ovary during ovulation is fertilized in the fallopian tube by a single sperm that has traveled up from the vagina. 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 until birth. But the Browns, married nine years, had been unable to conceive a child because of Lesley's faulty fallopian tubes. "Three years ago," Lesley says, "we were told that there was no chance that...
...sometime last November, Lesley Brown was given hormonal injections to stimulate maturation of her egg cells. Then, through a small incision in her abdomen, the doctors removed one or more eggs from the ovary, placed them in a laboratory culture medium and exposed them to her husband's sperm. At least one egg was fertilized, and the resulting conceptus began to divide, first into two cells, then four, then eight, and so on. A few days later, the conceptus had reached the blastocyst stage: an aggregate of cells in the form of a hollow sphere. Ordinarily, fertilization and this...
...pain during urination and a clear, watery mucoid discharge. The infection is not as readily apparent in women; chlamydia can remain unnoticed in the cervix, producing no apparent symptoms. Left untreated, the infection may lead to serious complications. Men can develop inflammation of the epididymis, which carries sperm from the testis. In women, inflammation may occur in the cervix or the fallopian tubes (which can become blocked, causing sterility) and other pelvic areas. Even worse, the infection can be passed on to babies during birth, causing eye infections and pneumonia. Says Epidemiologist Julius Schachter of the University of California...
