PGT<\/h1>\r\n
\r\n

Preimplantation genetic testing ( PGT)\u00a0<\/b>is allowed upon consent and permission from the\u00a0<\/span>Greek National Authority of Assisted Reproduction<\/b>,\u00a0\u00a0in order to prevent certain genetic diseases or disorders from being passed on to the child (PGT-M, PGT-SR or PGT-A). <\/span>PGT-A can also be used to identify causes of infertility in couples with <\/span>repeated miscarriages<\/span> or failures after IVF cycles (at least three failed attempts)<\/span>\u00a0(FEK 6549\/2022<\/a>)<\/span>\u00a0<\/span><\/p>\n<\/p>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n<\/section>\r\n\n\n\n

The rapid growth of Genetic Science enables the couples \u2013 and especially those with a serious family history \u2013 to bear healthy children.\u00a0<\/span><\/p>\n

Thanks to Pre-implantation Genetic Testing, those fertilized oocytes which have chromosomal aberrations and genetic diseases can be detected and precluded so that only the healthy ones will be transferred in the woman\u2019s uterus.<\/span><\/p>\n

 <\/p>\n

The procedure is not very different from a cycle of In Vitro Fertilization cycle, except that it includes the biopsy of the embryos in the embryology lab. With the process of biopsy, a few\u00a0 blastomeres (cells) from the growing embryos are isolated and analyzed in an appropriately trained genetic lab.<\/span><\/p>\n

 <\/p>\n

The biopsy of the embryos is performed in different stages\u00a0<\/span><\/p>\n

 <\/p>\n

    \n
  • The 3rd day post oocyte collection, to those embryos at approximately 8 cells was the first method to be used<\/span><\/li>\n
  • The 5th day post oocyte collection, to those embryos at the blastocyst stage. <\/span>The blastocyst biopsy is gaining more and more interest and tends to replace the day 3 biopsy, as it has many advantages as a method.<\/li>\n
  • Alternatively, polar body biopsy has been suggested to check the quality of maternal genetic material without intervening to the embryo, but due to limitations of the method it is not used routinely.<\/li>\n<\/ul>\n

     <\/p>\n

    The most common procedure following the biopsy technique is to freeze the biopsied blastocysts within a short period of time, until receiving the final results from the genetic laboratory. The embryo transfer is performed in a subsequent cycle, when women have an optimal endometrial preparation, with only the suggested embryos, so that to gain a healthy pregnancy.<\/span><\/p>\n

    Our embryologists’ training in the technique has already started since 2000 and continues until today with the most sophisticated educational protocols.<\/span><\/p>\n <\/p>\n <\/div>\n\n \n <\/div>\n\n \n<\/section>\n\n\n

    \r\n In which cases is Preimplantion Genetic Testing applied? <\/h4>\r\n
    \r\n \r\n

    PGT can be applied in very many diseases. We are proud for our high success rates in many cases of thalassemia and sickle cell anaemia as well as in rare diseases like neurofibromatosis, Stargart Syndromes, XLA, etc.<\/span><\/p>\n

    Sealing the success and the innovation that characterizes IVF Athens Center, we accomplished the first pregnancies worldwide of a woman with achondroplasia (nanism) after PGT. Embryo transfers in artificial cycles following cryopreservation and warming of healthy blastocysts were performed and thanks to the technique, the happy couple\u00a0 succeeded to have two beautiful, healthy children.<\/span><\/p>\n <\/span>\r\n <\/div>\r\n \r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/section>\r\n\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":6297,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-202","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/pages\/202","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/comments?post=202"}],"version-history":[{"count":29,"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/pages\/202\/revisions"}],"predecessor-version":[{"id":6172,"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/pages\/202\/revisions\/6172"}],"up":[{"embeddable":true,"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/pages\/6297"}],"wp:attachment":[{"href":"https:\/\/ivfathenscenter.gr\/en\/wp-json\/wp\/v2\/media?parent=202"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
