The childbirth is the happiest moments for any parents. Family planning is a challenging task. The entire family especially the parents have hopes on having a baby of specific gender. Although the theory says that the chances of having a baby boy or cute princess are 50/50, you might have come across families that have children of the same gender. This is where the importance of gender selection methods can be emphasized. With the revolution in science and technology in medical it has become possible to select your would-be baby gender. These new techniques have certainly eased the tension of many parents.

There are many innovative techniques that have evolved over the years that help get the best odds to achieve the desire gender. These techniques can also be used to prevent the transmission of genetic diseases. The method can also protect your child from sex-linked disease. There are many health centers that offer qualitative, safe and effective options to determine the gender. The two majorly used Gender Selection Methods are invitro fertilization and pre-implantation genetic diagnosis, abbreviated as IVF/PGD and Ericsson.

The Ericsson method has helped many families with gender selection of their baby. It is successful technique that involves selecting of ‘X’ and ‘Y’ chromosomes to have the baby gender of your desire. IVF/PGD is the latest and one of the most preferred methods by many doctors. It is a method that involves modern technology in gender selection. Vitro fertilization is involved in this kind of treatment. Eggs from female ovary are removed and allowed to fertilize with male’s sperm outside the woman’s womb. After the cell division takes place, the embryo of the preferred gender is decided and transferred back into the female’s womb. It has been observed that this technique has the highest success rates than other methods.

One of the sole reasons for going with the vitro fertilization is that it is immune to sex linked and gender based diseases. Thus, opting for this method will ensure that your baby is free of any complications and is healthy. The most common genetic hereditary disorder that gets transmitted by normal pregnancy is hemophilia. Children suffering from it suffer abnormalities in blood clotting if experienced breaking of blood vessels. It is majorly caused to lack of fibrin formation. Male child are mostly found suffering from hemophilic. It occurs when ‘X’ chromosome contains an infected gene. Therefore, it’s essential that you save your child from suffering such disorders by opting for IVF/PGD birth method.

When it comes to opting to these innovative ways of gender selection choosing the right method is of great importance. In order to take a wise decision it is essential to gather proper information of these methods. Going through reviews on sites and asking for references can help you make a wise decision in selecting the appropriate method. There are many health centers that you can approach to learn more about the various methods, they can help you decide the right method for you. You can browse the net to find a reputed and trustworthy medical expert to guide you through happiness.

•To father a son the ancient Romans believed that if you cut off the right (or was it the left) testicle you could influence the sex of your next child. Not only was this method very unsuccessful, but it was extremely painful as well! •Using the “Shettles” method of having scheduled intercourse around ovulation, and having the female climax first. Works as well as chance alone! •Using the Chinese calendar to time relations. Again works about 50% of the time, as well as by chance alone. •Hanging various colored items of clothing on the bed posts.

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.

Gender Selection Using the Ericsson Method

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.

IVF / PGD Gender Selection Technique

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.

Experimental Technique

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.

Fortunately, medicine has come up with better solutions. The Ericsson Method makes sperm race through a jelly. Although female sperm last longer in the vagina, they are slower swimmers and stay behind in the jelly. This lets the doctor divide the sperm and get a success rate of about 70% for your chosen gender. Some families want to make sure they have the gender of their choice. In these cases, the IVF/PGD technique is the best option for their families. IVF (in vitro
fertilization) is when the sperm is mixed with the egg in a test tube.
After a few days, the fertilized egg, called an embryo, grows into many cells. A specialist then uses PGD (Preimplantation Genetic
Diagnosis) to safely take one of the cells and look inside its DNA.
Every cell in your body has DNA that describes you and your gender.
From PGD, the specialist knows the exact gender of the embryo. He can then place the embryo of the gender that you want your baby to be back into the mother’s womb. The success rate for IVF/PGD is as close to perfect as humanly possible.

PGD enables the embryologist to biopsy the embryo and determine if a disease is present prior to selecting the embryo for transfer to the mother.

Every cell in the embryo contains a copy of the genetic makeup of the entire person. PGD begins with an embryo biopsy. A small hole is made in the egg membrane (zona pellucida) when the embryo has grown to 6-8 cells.

One cell is removed from the embryo so that the chromosomes can be examined. Removal of one of these cells does not harm the developing embryo.
