Read More About Family

If you are on the lookout for specialists who keep in mind the needs of families who have the want for a specific gender of their child to be born. You must visit The Silverman Center for gender selection website. Sometimes in joint families and extended families there is the need for the child to be of a particular gender. This is totally understood and hence the team of Dr. Silverman helps in determination of the child’s gender and also gives the required medical knowledge essential for the process of gender selection of the foetus.

Techniques for gender selection

The gender is determined by the chromosomes and the two types of chromosomes(X and Y) are helpful in gender selection. Now we will give the definition of chromosomes. The cells in the body contain the chromosomes, they are rod shaped and occur in pairs only. Each cell possesses 46 pairs of chromosomes except the reproductive cells that contain only 23 pairs.

When fertilization takes place these chromosomes combine together to form 46 chromosomes and out of these one pair, called the sex chromosome, is helpful in determining the gender of the baby. The sex chromosomes can be of the type X or Y. the female egg cell contains only X chromosomes while the male sperm cell contains both X and Y chromosomes. If the combination is X-X, the gender of the child is female and if it is an X-Y combination then the gender is male.

So if you want the child to be a boy you must select the sperm carrying Y chromosome to fertilize the egg cell that carries X chromosome and if you want a girl then the sperm carrying X chromosome must fertilize the egg cell with the egg chromosome for the result to be X-X pairing. This will help in gender selection of the child.

During the 1970’s, many of the eminent biologists found out that sperms that bear X or Y chromosomes can be obtained on purpose as it had been made evident that the result of a sperm carrying X chromosomes produces a girl and a sperm carrying Y produces a boy.

Dr. Ronald J. Ericsson, Ph.D. started his studies in 1975 to find out if the desired gender can be attained by proper chromosome selection. The study proved out to be quite a success and the Ericsson Method is now being used in many of the laboratories to predetermine the gender of the child.

Ericsson method involves a filtering process that is used to separate sperms bearing X and Y. Initially the sperms are all dipped in human serum albumin and this process is called “layering. Then they are made to flow down the entire gradient to be collected at the bottom.

Thus the sperms are separated into two layers. One contains only X chromosomes and the other Y chromosomes. Hence the required layer can be extracted and applied in the insemination technique. This method is successful to as high as 75%.
