Morphology of the Spermatozoa from Men Harboring Bi-allelic DNAH8 Variants
(A) Normal morphology of the spermatozoon from a healthy control male evident under light microscopy. Scale bars: 5 μm.
(B–E) Most spermatozoa from men harboring bi-allelic DNAH8 variants presented MMAF phenotypes, including absent (B), short (C), coiled (D), and irregular-caliberflagella (E). The data of subject A051 as an example.
(F) Normal morphology of the spermatozoon from a healthy control male as revealed by scanning electronic microscopy.
(G–J) The MMAF phenotypes, including absent (G), short (H), coiled (I), irregular-caliber flagella (J), were clearly revealed in the spermatozoa from subject A051 harboring bi-allelic DNAH8 variants.
