Second and third attempts will become easier and less costly with the wider use of cryopreservation, a process in which unused embryos are frozen in liquid nitrogen. The embryos can be thawed and then transferred to the woman's uterus, eliminating the need to repeat egg retrieval and fertilization. Some 30% to 50% of embryos do not survive the deep freeze. Those that do may actually have a better chance of successful implantation than do newly fertilized embryos. This is because the recipient has not been given hormones to stimulate ovulation, a treatment that may actually interfere with implantation...
Richard and Diana Barger of Virginia could be a textbook case of an infertile couple. Diana's fallopian tubes and left ovary are blocked with scar tissue, ironically the result of an intrauterine device (I.U.D.) she used for three years. Even if an egg did manage to become fertilized, the embryo might be rejected by her uterus, which has been deformed since birth. Richard has his own difficulties: his sperm count is 6.7 million per milliliter, considerably below the number ordinarily required for fertilization under normal conditions. Says Diana: "I never thought getting pregnant would be so difficult...
...meaning that a married woman is artificially inseminated by a male donor's sperm. The fifth formula, XD & YM by IVF with Gestation M, meant that the beginnings of life could be created through the uniting in a laboratory dish (invitro fertilization) of a woman's donated egg and a married man's sperm. Capron's final version - X1 & Y2 by IVF or Natural/ AΙ w/embryo flushing with Gestation 3 and Social Parents 4 & 5 - outlined how a baby could theoretically have five different "parents...
...Capron testified before a House science subcommittee early last month, "Many the new reproductive possibilities remain so novel that terms are lacking to describe the human relationships they can create. For example, what does one call the woman who bears a child conceived from another woman's egg? I'm not even sure we know what to call the area under inquiry...
...acquire babies. And the varied fertility controversies that reach the courts are sometimes of a rending intensity. In New York City, for instance, a Florida couple named John and Doris Del Zio in 1973 became the first couple in the U.S. to attempt IVF. An infertility specialist removed an egg from Mrs. Del Zio, put it in a container and handed it to her husband, who raced across town in a taxi to deliver it to the Columbia-Presbyterian Medical Center. There, another doctor fertilized it with some of Del Zio's sperm and stored it in an incubator...
