Albumin Filtration Method
WHAT IT IS: Developed by Ronald Ericsson, Ph.D., and popularly known as the Ericsson Method, this technique, separates X- and Y-bearing sperm by spinning them in a centrifuge.
HOW IT WORKS: The lighter Y-bearing sperm rise to the top and the heavier X-sperm sink. Once the sperm are isolated and collected according to the desired sex, they are inserted by intrauterine insemination. If the couple is trying for a girl, Ericsson also recommends that the woman take the fertility drug clomiphene citrate, which is generally taken to increase the production of eggs. Although he can't explain the correlation, Ericsson notes that in his experience the drug has seemed to increase the chances of couples conceiving girls.
SUCCESS RATE: According to studies published by Ericsson, the albumin filtration method has a success rate of more than 80 percent for parents wanting boys and 73 percent for those wanting girls, figures that he says have been confirmed in more than 40 clinics worldwide that use his technique. Other doctors of reproductive medicine, however, say that other scientists have been unable to reproduce Ericsson's results.
WHO IS ELIGIBLE: Anyone who can afford it.
COST: $500 to $1,000 per menstrual cycle (it can take at least two or three menstrual cycles to conceive).
