Ultrastructural pathology of varicocele spermatozoa by using atomic force microscopy (AFM)

Ultrastructural investigation of pathological spermatozoa of patients having varicocele (grades I and III) in its natural environment (without fixation, dehydration, embedding, sectioning, etc.) was carried out by using Atomic Force Microscope (AFM) in tapping mode. This is a unique technique to examine the topographical structure with precision and to obtain 3-D images. It revealed structural alterations caused by the presence of varicocele. Not only neckpieces and flagella were defective, but also the head; particularly, dimensions and heights are altered.
