Spindleview and Embryoscope: Providing a Better Chance of Success in IVF


Spindleview, also called “Oosight”, is a computerized high power microscope that allows the embryologist to see the internal structure of each retrieved egg (oocyte) or embryo.

This is cutting-edge technology used by the TRIO lab in two important ways: First, to visualize the spindle of each egg very accurately when performing ICSI (injecting one sperm into one egg to aid fertilization). Why is this important? In one third of retrieved eggs, the spindle is not in its expected position. As a result, without Spindleview technology, an embryologist can only make an educated guess when injecting the sperm cell into the egg. With Spindleview, the procedure will be more accurate and ultimately, has a greater chance at successful fertilization. Second, Spindleview gives the embryologist a clearer picture of overall egg quality. Without Spindleview, it is more difficult to assess the quality of a group of eggs retrieved during a cycle. Our lab has demonstrated that Spindleview technology has increased the number of fertilized eggs and therefore, the number of developing embryos per cycle.

TRIO is proud to be a pioneer in Spindleview use in North America. We believe this technology gives our patients the opportunity to have both a better quantity and quality of embryos, giving both patients and their physicians a
better insight into the details of the IVF cycle.


The Embryoscope is a state-of-the-art time-lapse incubator used to culture and grow embryos in the TRIO lab. Standard incubators require developing embryos to be removed on a regular basis to observe their growth at various stages. Even though the embryos are placed back in the incubator as soon as possible, removing them can potentially negatively affect growth and development because embryos are quite sensitive to temperature changes and exposure to light. The fact is, there is a risk every time an embryo has to be removed from an incubator. This risk is eliminated with the Embryoscope: once embryos are placed inside this special incubator, they are not removed for the next five to six days. Embryo growth and development is assessed using time-lapse videography, giving the embryologist a more complete picture of the developing embryo over a full 24-hour period. And because all this takes place from within the incubator, the embryo is not subjected to changes in temperature or light. TRIO lab research indicates that Embryoscope technology has resulted in a 9% increase in pregnancy rate and a 20% improvement in maturation to the blastocyst stage (mature embryo) compared to standard incubators.

At TRIO, we believe very strongly that Spindleview and Embryoscope are extremely important state-of-the-art technologies that provide patients with a better chance of success in every IVF cycle. In fact, both technologies are used in every private IVF cycle that we do here at TRIO. Unfortunately, at the moment, government-funded IVF does not cover these advanced technologies. Although there is an additional cost not covered by OHIP, we encourage you to consider using Spindleview and Embryoscope as a way to increase your chances of success if you are doing a government-funded IVF cycle here at TRIO.
