IMSI is an advanced ICSI method descibed by Bartoov et al. (in Journal of Andrology 2002, 23). Prior to sperm injection the morphology of the sperm cell is evaluated with high magnification DIC microscopy.
Leica offers an aplication optimized system called the Leica "Big S". This has been developped in close cooperation with the lab of Prof. S. Viville, Strassbourg, France. (see Wittemer .....) AM6000 with "Big S" has been installed in multiple IVF labs.
