Morphometric studies of development of the rat testis under physiological conditions and after CdCl2 poisoning

The morphometrical data of the rat testis were studied between the 1st day and 1.5 year of life under physiological conditions and after intraperitoneal injection of a single dose of cadmium chloride (1.5 mg CdCl2/kg body weight). Under physiological conditions three main period of development occur: between the 1st and 30th day of life, between the 30th and 45th day of life, and after the 45th day of life. The greatest changes after the injection of cadmium were noticed in the period between the 15th and 30th day of life. The periphery of the organ was the first to suffer severe damage.
