Using the Aarhus transmission X-ray microscope we have shown that the mitochondria of human spermatozoa can exist in two morphologically distinct states. We have also discovered new structures on the human spermatozoon surface. These structures manifest as clear vesicular bodies associated with specific membrane domains. They can occur around the acrosomal segment, the mid-piece region or at the basal region. Prior to our findings they were not described in the literature, even though they were clearly visible by light microscopy and ubiquitous among populations of sperm from fertile donors. We report on our findings and subsequent endeavours to elucidate the function of these fascinating structures.
