# Polarizer

The polarizer is an optical system integrated in a microscope based on the different polarization indexes of light. With this technique we can observe the most important structures in the oocyte, such as the meiotic spindle” (inner structure of the egg where its genetic material is concentrated) to prevent from damaging it in the microinjection process, thus increasing the fertilisation rate.

We can also identify the stages of ovocitary maturity perfectly, analyze the oocyte very precisely after the freezing and unfreezing procedures and improve the efficiency of the polar body and embryo biopsy techniques in cases of Preimplantational Genetic Diagnose (PGD).
