The dye enters dead sperm within 1 minute, sperm should be classified. Binocular viewing head makes the microscope comfortable for extended viewing. Binocular eyepieces make it more comfortable for viewing and eliminate the need to close one eye when looking through the microscope.
Spermatozoa showing green labeling display detectable level of DNA methylation. Papanicolaou staining, Semen analysis, Sperm-head vacuole, Sperm morphology. The post-acrosomal region should not contain any vacuoles. Site Map Privacy Policy. Sperm migration was performed with a bilayer discontinuous gradient.
