Keith Blauer, a reproductive endocrinologist at Microsort, says: "That is the policy for the clinical trial. babies Chinese pregnancy gender calender. What will happen in 5, 10 years will depend on what society wants. "icrosort's decision to accept requests to balance families led to several surprises. The first was the discovery that the technique is better at producing girls than boys. babies Chinese gender predictor. While the success rate for daughters is 93 percent, it is only 73 percent for sons. Fugger attributes that gap, in part, to practice. "When we started, we were sorting only for the X sperm because we were only interested in the X-linked disease disorders," he says. babies Prenatal gender test. "So we have a longer experience with that than we do with the Y. " Another reason is the nature of the Microsort machine. "The instrument determines the X and Y based on the fluorescent intensity. X sperm are fuller and brighter, and Y sperm are dimmer. It is easier, at least at the level of technology today, to determine a bright cell rather than a faint cell. " The second surprise was that Americans, unlike much of the rest of the world, do not prefer boys. Of the first 111 Microsort attempts, 83 were for females and 28 were for males. True, the process began as a way to select for girls, and true, because it is better at selecting girls it is more likely to attract couples who want them. But there is something else going on as well, something Shettles and Ericsson learned a long time ago. "More want girls," Shettles says. "Definitely we heard more from women who had many boys and wanted a girl. "Ericsson, too. "We see more requests for girls," he says. At some Ericsson clinics, the ratio is as high as 2 to 1, despite Ericsson's own statistics showing a higher success rate for boys. It is, he says, a gap that has been growing since he first introduced his method 25 years ago. In a lopsided, counterintuitive way, he insists, this is a streak of feminism, although it hardly appears that way at first, what with all the talk of ponytails, dresses and bows. "Women are the driving force, and women want daughters," he says. "And they're not apologizing about it anymore.
