Figure 1 The morphology and ultrastructure of spermatozoa from two
patients. (a) Sequence chromatograms of two patients. Sanger sequencing
confirmed the SOHLH1 mutation in the patients. The red arrow
denotes the mutation site (NG_033784.1: c.346-1G>A). (b)
Papanicolaou staining of patients’ sperm, most of which were amorphous
head and irregular flagella. (c) The abnormal sperm phenotypes were
observed in the patients by SEM. (d) TEM showed the abnormal
ultrastructures of the head and flagella from the patients’ spermatozoa.
