Spindle observation system
Spindle is a method of observing egg maturity using a special lens. This method helps to time the egg fertilization process correctly. In order for the egg to be successfully fertilized, it must be mature. The maturity of the egg is recognized due to the presence of a polar body. Real maturity is recognized only by the position of the dividing spindle in the egg.
Using the spindle method, the embryologist sees the position of the dividing spindle and selects the optimum time for fertilization. This method is used to increase the success of fertilization in cases where a small number of mature eggs have been obtained.
