Gender Selection Methods
Proven Techniques of Gender Selection and How is the Gender of a Baby Determined?
Gender selection is possible because of how sex is determined by our chromosomes. Our bodies are made up of billions of cells. All cells contain 46 rod-like forms arranged in pairs called chromosomes, except for the special reproductive cells, the sperm and egg cells, called gametes, each of which only possess 23 chromosomes.
During fertilization, the gametes combine and restore the normal chromosome number (46) in the embryo. One of these pairs of chromosomes defines the sex of the developing baby. This pair is called the sex chromosome. Each sex chromosome is made up of an “X and Y” chromosome, which define a male, or an “X and X” chromosome, which define a female. Eggs can only contain X chromosomes, but sperm contain either an X or a Y chromosome.
If you want a boy, you select sperm containing the Y chromosome, so that during fertilization, the sperm’s Y chromosome will pair up with the egg’s X chromosome. If you want a girl, you select sperm containing the X chromosome, so that during fertilization, the sperm’s X chromosome will pair up with the egg’s X chromosome.
Gender Selection using the Ericsson method, has a proven record of success. Dr. Silverman has been practicing the Ericsson Method for over 20 years.
After ovarian stimulation, eggs are removed from the mother. These eggs are fertilized in the laboratory using the father’s sperm. After cell division, the embryos are checked for their sex. Only the embryos of the chosen gender are transferred back to the mother.
Dr. Silverman has been practicing in vitro fertilization over 30 years, and is now offering IVF with preimplantation genetic diagnosis (PGD). Since only embryos of the desired sex are transferred to the mother, gender selection success rates for IVF/PGD are high.
Unreliable Gender Selection Techniques
The Shettles Method:
The gender selection technique, the Shettles method, theorizes that sperm containing the X (female) chromosome are stronger than sperm containing the Y (male) chromosome, so they survive longer. Therefore, intercourse two to four days prior to ovulation means that the female sperm are more likely to survive and cause fertilization. Intercourse close to ovulation should increase the chances of having a male since the concentration of Y sperm should be higher at the female’s most fertile time.
The Whelan Method:
Gender selection using the Whelan method is another “intercourse timing scheme” that suggests the opposite of the Shettles method. This method suggests intercourse four to six days prior to ovulation to increase the chance of having a boy.
Gender Selection Using Microsort:
Gender selection using the Microsort procedure sorts sperm in vitro, and then inseminates a higher percentage of sperm of the desired gender into the uterus. Microsort sorts sperm using a laser light. Microsort is operating under FDA guidelines, and is therefore considered an experimental technique.
Which Gender Selection Option Is Right for Your Family?
The first step in your search for help with gender selection is to decide how important your next baby’s sex is to you and your family. The Ericsson Method of gender selection increases your odds of having a child of your chosen gender. If you feel that you could not accept a child that may not be the sex that you wanted, then this technique is not for you.
You should consider the IVF/PGD gender selection technique since gender selection success rates with this procedure are much higher. If you are at risk for a sex linked genetic disease, the IVF/PGD technique is more effective in preventing the transmission of this genetic disease to your next child.
