A third California woman, identified only as a 23-year-old resident of Tracy, has become pregnant using an experimental frozen embryo transfer program. Dr. Glen Zorn, director of the in vitro fertilization program at John Muir Hospital in Walnut Creek, announced the pregnancy. Last week, Dr. Richard Marrs of Good Samaritan Hospital in Los Angeles announced that two women there had become pregnant through frozen embryo transfer and that one is expected to give birth in June. That would be the first birth in the United States through the procedure, in which an embryo is conceived in a laboratory dish, frozen in a vat of liquid nitrogen, stored for a period, then thawed and implanted in the woman.
