What is Cytological evaluation of spermatogenesis within the germinal epithelium of the male European wall lizard, Podarcis muralis about?
## Abstract The annual cytological changes to the male germinal epithelium were investigated in an introduced population of European wall lizards (__Podarcis muralis__). Testicular tissues were collected, embedded, sectioned by an ultramicrotome, and stained with the PAS procedure followed by a toluidine counterstain. Spermatogenesis in the lizard is divided into the proliferative, meiotic, and maturational phases. Wall lizards have a prenuptial pattern of spermatogenesis, where sperm development begins immediately prior to and continues through the months of breeding (April‐June). The testis then involutes, undergoes a short period of quiescence, and recrudescence commences in mid‐July. Germ cells undergo proliferation, meiosis, and the early stages of spermiogenesis (maturation) from late July through December. However, the late stages of spermiogenesis are retarded from December through February. Spermiogenesis continues at an accelerated pace from March through May, leading to a single massive spermiation event through the month of June. Although spatial relationships are seen between germ cells within the seminiferous epithelium, accumulation of spermatids during winter and ac
