Isolation of High Quality Sperm using SpermPrep™

In order for fertilization to occur, high quality, motile spermatozoa need to be separated from the seminal specimen. Since there is great diversity in semen profiles, especially among infertile men, here at AIA, each specimen undergoes a special "tailor-made" procedure to isolate the best sperm for ART and IUI. For this purpose, we have developed numerous innovative techniques depending on the quality of the specimen. Among these are the SpermPrep I and II columns, the ZSC I, ZSC-II and Multi-ZSC technologies, all developed by our very own Research and Development Program at AIA (5,6,7).
