Spermatology: Current Methods to Study Sperm Classical Variables.

It was back in 1677 when most researchers agreed that spermatology started, supported by van Leeuwenhoek's report about sperm discovery when demonstrating his novel microscope. Since then, multiple approaches have been applied to elucidate key aspects of the morphology of the male gamete and whether they would prognose fertility. Curiosity advanced in parallel with the many analytical tools, including the currently highlighted omics, which opened a yet unexplored scenario where researchers are worldwide trying to describe in detail not only the structure but also the mechanism behind sperm function.
