PPT-Sperm selection based on birefringence

The presence of birefringence is the expression of an organized and very compact texture that characterizes normal sperm nuclei acrosomes and motile tails On the basis of these considerations the application of polarization microscopy to the ICSI technique has been proposed as a novel tool for sperm selection based on the properties of birefringence that human spermatozoa naturally possess. Commonly used sperm viability assays em ploy mixtures of two or three dyes including fluorescein di acetate derivatives rhodamine 123 and reduced nucleic acid stains which target a variety of cellular components 14 Acridine orange which fluoresces a brPage 1br photoelastic modulators Birefringence Measurement brPage 2br photoelastic modulators Birefringence Measurement brPage 3br photoelastic modulators Birefringence Measurem Bioinspired.
