Before long, though, they may have a better way to make a baby. This week, Alan Trounson, an IVF pioneer at Monash University in Melbourne, Australia, will tell the American Fertility Society meeting in San Antonio, Texas, that he and his colleagues have devised an alternate approach that is much cheaper, simpler and easier on the mother. It removes the need for fertility drugs and daily monitoring. "There is nothing terribly complicated about ((the procedure))," Trounson claims, "so it will spread like a brush fire because the patients want...

Instead of priming the woman with fertility drugs so that eggs (the oocytes) will mature, doctors simply remove immature eggs. The timing is no longer crucial. Success hinges on two new techniques: locating the immature eggs and stimulating them to mature outside the ovary...
...process begins with an examination of follicles, the tiny sacs in the ovary where eggs are found. Fertility doctors ordinarily focus on large follicles -- nearly a half-inch wide -- that contain mature eggs. But Trounson's partner, Dr. Carl Wood, discovered that the latest ultrasound machines could spot follicles that are less than a tenth of an inch wide and hold immature eggs. Wood developed a way to pluck the young eggs out of the smaller follicles with a specially designed needle. Trounson, after experiments with cattle, devised a cell-culturing procedure that ripens the immature eggs in the laboratory...

Unable to conceive naturally with her husband Tim, a grain farmer in Hopetoun, Australia, Robyn tried fertility drugs to no avail. As the couple prepared to undergo traditional IVF, they were offered Trounson's new approach. "We were told that there'd never been a baby born through this procedure," Robyn recalls. "We thought, 'What do we have to lose...
