[Establishment of an animal model of azoospermia in male mice].

Objective: To establish a stable animal model of azoospermia in male mice.

Methods: Two groups of mice, with 30 in each, were intervened respectively by chemotherapy (intraperitoneal injection of Busulfan and Cyclophosphamide) and subcutaneous injection of Estradiol. At different times after the injection, the microscopic structures of the seminiferous tubules of both groups were observed and compared. The recovery of the germ cells in the seminiferous tubules was also evaluated after the termination of the intervention.

Results: A stable animal model was established by chemotherapeutic method with Busulfan and cyclophosphamide, while the model constructed by muscle injection of Estradiol was not stable.

Conclusion: Compared with estrogen injection, chemotherapeutic intervention is a reliable method for constructing an animal model of azoospermia in male mice.
