What are the different ways of performing the embryo biopsy procedures?
There are three methods of biopsy procedures: mechanical, chemical, and laser zona drilling. With mechanical methods, an incision or hole is made in the zona pellucida (the outer layer) using a tool such as a microsurgical knife or a special glass needle. The chemical method directs a stream of acidic solution to digest a portion of the zona pellucida. Laser zona drilling uses a highly focused laser beam to remove the zona pellucida in very precise increments.
