Quantitative evaluation of spermatogenesis by fluorescent histochemistry

AbstractIdentifying the types of spermatogenic cells that compose seminiferous tubules, as well as qualitative confirmation of the presence or absence of disorders, has been regarded as crucial in spermatogenesis. Sperm count and fertilizing capacity, both of which depend on the quality as well as quantity of spermatogenesis, are factors critical to fertilization. However, the quantitative assessment of spermatogenesis is not commonly practiced. Spermatogenesis has species-specific stages; when the specific stage in the seminiferous tubules is precisely determined, the types of spermatogenic cells in each stage can be spontaneously identified. Thereafter, a unique marker is used to classify the cells observed in each stage. Quantitative assessment of spermatogenesis has the potential to detect inapparent spermatogenesis disorders or numerically indicate the degree of the disorder. To this end, a histochemical approach using unique markers is indispensable for the quantitative assessment of spermatogenesis. Future developments in techniques to measure cell populations using computer software will further facilitate the establishment of quantitative assessment of spermatogenesis as a standard analysis method that can contribute significantly to advance our understanding of spermatogenesis.
