As a result, the embryologist is able to more precisely select the best oocytes for the in vitro fertilisation procedure. This increases the chances of achieving high-quality embryos and, consequently, pregnancy and childbirth. Oosight is one of the latest technologies to increase the effectiveness of IVF.\u00a0<\/strong><\/p>\n\n\n\n<p>The quality of the oocytes shows an important influence on the viability of the embryo, the subsequent development of the foetus and the course of the pregnancy. It is important both in nature and in the treatment of infertility by assisted reproduction methods. In the case of in vitro fertilisation procedures, the quality of the oocytes has a huge impact on the success of the treatment. In many cases, looking at the oocytes under the microscope with the Oosight system can have a real impact on IVF success, achieving pregnancy and having a baby.&nbsp;<\/p>\n\n\n\n<p><strong>Oocyte quality is of paramount importance for the competence of the embryo for development, implantation and subsequent fate of the foetus.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table style=\"border-style:dashed;border-width:3px\"><tbody><tr><td><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-color-12-color\">Embryological consultation <br><\/mark><br>If additional questions come to mind after reading this article, remember that all Invimed patients qualified for insemination or IVF can benefit from the <a href=\"https:\/\/invimed.pl\/en\/konsultacja-embriologiczna\/\" target=\"_blank\" rel=\"noreferrer noopener\">free embryological consultation<\/a>.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ocena-morfologiczna-oocytow\">Morphological evaluation of oocytes<\/h2>\n\n\n\n<p>The ideal mature human oocyte, in terms of morphological characteristics, should be a closed, spherical structure.

The Oosight-enabled determination of the presence and exact positioning of the spindle during ICSI\/IMSI results in an even higher success rate for these procedures.
