Preimplantation Genetic Diagnosis<\/h1>\n\n\n\n

The objective of genetic analysis of embryos is to be able to transfer those diagnosed as healthy.<\/p>\n\n\n\n

What is PGD?<\/h2>\n\n\n\n

Preimplantation Genetic Diagnosis (PGD) is a technique that consists of genetic analysis of embryos<\/strong> in early stages of their in vitro development with the ultimate goal of being able to transfer those diagnosed as healthy<\/strong> for the genetic study performed.<\/p>\n\n\n\n

<\/div>\n\n\n\n

PGD must necessarily be linked to assisted reproduction techniques. Couples must undergo a cycle of In Vitro Fertilization<\/strong><\/a>, since ovarian stimulation and subsequent oocyte retrieval through vaginal puncture must allow obtaining a sufficient number of oocytes and, subsequently, embryos, to guarantee the transfer of at least one normal embryo for the genetic diagnosis studied. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Preimplantation Genetic Diagnosis was proposed as an alternative to prenatal study, trying to avoid pregnancy terminations in cases of affected fetuses<\/strong> and was directed at patients with serious hereditary diseases<\/strong>.<\/p>\n<\/div>\n\n\n\n

\n

In which cases is PGD indicated?<\/h3>\n\n\n\n
\n
\n

Patients with serious hereditary diseases:<\/h4>\n\n\n\n

Law 14\/2006, of May 26, on Assisted Human Reproduction Techniques allows authorized centers to perform this type of diagnosis in case of serious hereditary diseases, of early onset and not susceptible to curative treatment<\/strong>, in accordance with current scientific knowledge; as well as for the detection of other alterations that may compromise the viability of the embryo<\/strong>.<\/p>\n<\/div>\n\n\n\n

\n

Other purposes:<\/h4>\n\n\n\n

The application of preimplantation diagnostic techniques for any other purpose<\/strong> or when intended to be practiced for therapeutic purposes for third parties<\/strong> will require express authorization, case by case, from the corresponding health authority<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
