The influence of hexestrol diacetate on gametogene function in male rabbit.


PMID 21424085

Abstract

The research was performed on 24 male sexually mature domestic rabbits, divided in two equal batches. The rabbits from the first batch were administered 0.5 mg/kg of body weight hexestrol diacetate intramuscularly twice a week for four consecutive weeks. Batch 2 was used for control. The testicular tissue samples obtained after orchidectomy were processed in order to obtain histological samples, stained using the Goldner's trichrome method. Examination of histological sections from the control batch showed that a natural aspect of seminal tubule epithelium, without reported injuries, even discrete. In the experimental batch were recorded a number of changes to all categories of the seminal cells. The severity and extent of damages varied greatly from one seminal tube to another and even from one part to another of the same seminal tube. These changes were the appearance of apoptotic cells and apoptotic bodies, vacuolar degenerescence of spermatocytes and spermatides, syncitialisation of spermatides, areas of necrosis accompanied by severe disruption of the seminiferous epithelium. In some areas, the lesions were so severe that the affected area of the cells forms "basal area". If lesions in the "adluminal area" affects only temporarily gametogenetic function the lesions in the "basal area" are irreversible as there are named "reserve cells" which is the starting point of spermatogenesis. Highlighted issue raised on the opportunity use of hexestrol diacetate in therapy or animal production stimulation as it gametogenetic function in males while their risk transfer to humans through consumption of foods of animal origin.
