title: Possible applications of lasers in assisted reproductive technologies.
abstract: Laser systems seem to be the most promising technical tools to be introduced in assisted reproduction treatment in recent years. The 1.48 microm diode laser in particular is on course to supersede conventional mechanical and chemical methods for opening the zona pellucida in assisted hatching, and for biopsy of polar bodies or blastomeres. This is because it works without physically touching the cells, has no traceable toxic effects on living cells and is easy to handle. There will be manifold future possibilities for micromanipulation with lasers, as already demonstrated by the immobilization of spermatozoa prior to intracytoplasmic sperm injection, and the successful dissection of the zona pellucida into two halves with equal diameter for the hemizona assay.
