Special Sperm Morphology - Andrology Applications

Kruger strict criteria staining differentiates normal (<4% abnormal) vs. teratozoospermia across ICSI candidate selection workflows.

Fertility laboratories quantify head defects (tapered, pyriform) confirming IVF failure risk. Acrosome contrast prevents normal morphology overestimation.

Quality control confirms acrosome staining, midpiece integrity, and WHO 5th edition compatibility. Specialized fixation prevents shrinkage artifacts.
