Upon completion of spermiogenesis, LGR1 immunoreactivity was not associated with spermatozoa, but rather detected in the cyst cytoplasm as punctate foci that are encapsulated within F-actin stained waste bags (Figure 1D) (Texada et al., 2008), which are organelles responsible for disposing of excess contents after sperm individualization (Metzendorf and Lind, 2010). This evidence concerns the gene FSHR and cyst.
