Ericsson Method of Sex Selection:
Up until recent times, authorities still advised couples to change time and frequency of intercourse or even alter diets to cause the conception of either a male or a female child. Scientists know that sperm carrying an X chromosome determines a female and one carrying a Y chromosome determines a male. However in 1970, researchers discovered that a male or Y chromosome bearing sperm could be stained with a dye, finally allowing researchers to scientifically study sex selection procedures. Subsequently, many methods for separation of X from Y chromosome sperm were tested.
The technique developed by Ronald Ericsson, Ph.D., of Gametrics, Ltd., Montana, www.childselect.com for sex selection has been used extensively and is presently offered by numerous centers in the United State and worldwide.The process for both the male and the female selections begin with the sperm filtration. Although the two procedures differ in concentrations and incubation, they both are similarly filtered through a salt protein solution within isolation columns (or small test tubes). At the final incubation, the bottom layer of the filtration is collected and processed for artificial insemination. This is a procedure where the physician will place the prepared specimen either intra-cervical/ICI (female procedure) or intra-uterine/IUI (male procedure). For the female selection, the sperm filtration technique is used in conjunction with a fertility drug, clomiphene citrate, to change the cervical mucus, for the insemination of the sperm. There is no extra medications needed for the male procedure. On occasion, we give an injection of HCG for women who have menses cycles that are sporatic or for better timed ovulation of our out of town couples for purposes of better timed ovulation.

Our Success Rates:
Success rates vary with each couple. It can depend on a persons age, medical conditions, menses or timing of ovulation, just to name a few. Even couples who have had a few children without any incidents or complications and conceived easily, may still take several cycles to become pregnant. It is important to remember that each pregnancy is different and not dependent on the other. We have 25% of our clients become pregnant in the first cycle. That being said, the other 75% may take 2 to 10 cycles, depending on the individual couples. The success for the male selection is approximately 80%- 83%, and the female procedure is approximately 75%- 78%. On an average, conception has been occurring for both procedures after 3 to 5 cycles. On average, couples who have had more than 4 IUI cycles, have a >80% chance of conceiving and a 75% chance of achieving the gender of choice.
