Figure 7From: The application of scanning near field optical imaging to the study of human sperm morphology Human spermatozoa having morphological anomalies as imaged by SNOM. (A) 3D SNOM topography of two tail spermatozoa: blue arrowhead indicates the end of midpiece, while red arrow indicates the end of post-acrosome area. (B) SNOM optical reflection and (C) transmission images. (D) 3D SNOM topography of a zoomed scan area of midpiece region together with SNOM reflection (E) and transmission (F) images. (G) 3D SNOM topography of a coiled sperm and corresponding SNOM optical reflection (H) and (I) transmission images.Back to article page
