As part of a fertility investigation, specialized tests can be performed that help us identify hereditary or chromosomal abnormalities, which may affect conception or the development of a pregnancy.<\/p>

Basic tests include:<\/p>

  • Peripheral blood karyotype<\/strong><\/p><\/li>

  • Screening for mutations associated with Cystic Fibrosis<\/strong><\/p><\/li>

  • Detection of microdeletions on the Y chromosome<\/strong><\/p><\/li><\/ul>

    What is Karyotype?<\/strong><\/h3>

    karyotype<\/strong> is the test that allows us to evaluate the number and structure of chromosomes<\/strong>. Chromosomes are located in the nucleus of cells and contain the genetic material (DNA) that determines hereditary characteristics.<\/p>

    Normally, each cell in the human body has 46 chromosomes<\/strong>, organized into 23 pairs<\/strong>:<\/p>

    • 23 chromosomes come from the mother<\/p><\/li>

    • 23 chromosomes come from the father<\/p><\/li><\/ul>

      The only exception is eggs and sperm<\/strong>, which have 23 chromosomes each<\/strong>, so that during fertilization the embryo results with the normal number: 46 chromosomes<\/strong>.<\/p>

      When is Karyotype testing important?<\/strong><\/h3>

      If one of the two parents carries a chromosomal abnormality<\/strong>, it can be transferred to the eggs or sperm and, by extension, to the embryos that are created.
      This can lead to:<\/p>

      • repeated implantation failures<\/strong><\/p><\/li>

      • recurrent miscarriages<\/strong><\/p><\/li>

      • infertility without apparent causes<\/strong><\/p><\/li><\/ul>

        The probability of an infertile couple having a pathological karyotype is estimated at approximately 4%<\/strong>.<\/p>

        How is the examination performed?<\/strong><\/h3>

        The test is performed simply by taking blood<\/strong> and does not require any special preparation.
        In the context of assisted reproduction, the karyotype is a essential tool<\/strong>, because it can:<\/p>

        • to guide treatment choice<\/p><\/li>

        • to reduce the risk of miscarriage<\/p><\/li>
