Pre implantation genetic diagnosis or PGD is a procedure thats undertaken before the implantation of a womans uterus with fertilized embryos. Thanks to medical advancements such as PGD, it is possible to identify any genetic defects within the IVF embryo. Countries like Cyprus offer excellent fertility treatment facilities.
How is it performed?
The IVF treatment normally encompasses processes such as ovary stimulation via medicines, egg and sperm retrieval followed by fertilization. It is kept in the lab for 3 days when the embryo will get divided into 8 cells. Some of the cells may be removed from within the embryo and the DNA retrieved. Through molecular analysis, the DNA code is studied to determine if a problematic gene has been inherited.
Benefits of PGD in Cyprus
Since the procedure is conducted before implantation, it reduces the need for amniocentesis or medical termination of pregnancy at a later stage of pregnancy. Couples can make an informed decision whether they want to continue with the pregnancy or not. In the long term, it may help reduce costs for couples who would otherwise incur in bringing up a child with birth defects.
Who is it recommended for?
When couples approach a fertility clinic, they are most likely to be screened for genetic conditions and are identified to be carriers of certain potential diseases. Carriers of single gene defects, sex linked genetic disorders, women with chromosomal disorders, women who are 35 years or older, and those who have undergone recurring pregnancy losses due to chromosomal concerns are recommended to take the PGD in Cyprus.
Conditions that Can be Identified
PGD tests identify presence of disorders such as hemophilia, neuromuscular dystrophies and fragile X syndrome these are called recessive sex linked disorders.
Disorders such as Vitamin D resistant rickets and Rett Syndrome come under the category of dominant sex linked disorders. Disorders such as Tay-Sachs, cystic fibrosis, sickle cell anemia and Huntington Disease come under single gene disorder all of these can be identified.
Besides these, chromosomes responsible for conditions such as Pick Disease, Wilson Disease, Downs syndrome, acute myeloid leukemia, ovarian cancer, breast cancer and pancreatic cancer can also be identified.
Gender Selection Cyprus
Some disorders are gender specific and when such a situation arises, fertility clinics in places such as Cyprus give their patients the choice of gender selection that is patients can select healthy embryos.
The concept of sex selection has ethical considerations but the laws of Northern Cyprus have given their nod to this procedure. However, there are some checks and balances.
Sex selection in Cyprus is allowed to promote the concept of family balancing. Only couples who already have at least 1 child have the right to apply to the clinic and request for a sex selection procedure. According to rules, couples who do not have any children cannot make such request.
It must be kept in mind that the PGD procedure doesnt completely eliminate the chances of gene disorders. Studies are still incomplete and there are many disorders for which genetic causes have not been discovered yet. If genetically present, some diseases may show symptoms when the affected person reaches middle age. It is necessary for patients to display caution and sagacity when dealing with PGD test results and gender selection.
