The goal of this study was to look at the phases and processes of spermiogenesis in Yangzhou geese ganders, as well as morphological alterations in the seminiferous epithelium. Yangzhou goose is a synthetic breed produced in China using native goose genetics. Because of its great productivity and versatility, it is prominent in the Chinese geese industry. It is impossible to achieve maximum hatchability and fertility in the geese sector without focusing on gander reproductive health. The age of maturity and reproductive health of animals are both determined by determining the phases of spermatogenesis. Over the last three decades, the global goose business has changed dramatically. China has the greatest goose breeding stock in the world, accounting for 95% of the total. Due of the low reproductive success of most goose breeds, an emphasis on This study looked at the phases of spermiogenesis as well as morphological changes in the seminiferous epithelium in Yangzhou geese ganders. The seminiferous epithelium cycle was studied using testis slices immersed in melted paraffin wax. Early phases of spermiogenesis were represented by alterations in acrosomic granules, whereas later stages were identified by changes in nuclear morphology. There are ten stages of spermiogenesis and nine stages of seminiferous epithelium. There are four forms of spermatogonia: Ad, Ap1, Ap2, and B. The diameter of seminiferous tubules (ST), epithelium height (EH), and luminal tubular diameter all varied significantly (LD), , the Johnsen score, and the quantity of seminiferous tubules per field Other birds and mammals had comparable stages of seminiferous epithelium, and the ST diameter, EH, LD, and Johnsen score were all positively associated, while the number of seminiferous tubules per field was negatively related. Visualizing the histological development of germ cells in testis tissues during spermatogenesis following the breeding season and maturity would assist Yangzhou ganders become more fertile.
