Cytological changes of the epithelial cells according to the developmenatal phases of the seminal vesicle related to the spermatogenic stages in the testicular lobules during spermagenesis in male Neptunea (Barbitonia) cumingii (Gastropoda: Buccinidae) were investigated monthly by electron microscopical and histological observations. N. (B) cumingii is dioecious, and an internal fertilization s...

Previous studies on the metabolism of semen have furnished evidence that the reducing carbohydrate in seminal plasma is fructose, which is readily converted by the spermatozoa to lactic acid, thus providing an important source of energy for the sperm cells (Mann, 1946a, b, c). The rate of fructolysis represents an accurate and at the same time simple means of evaluation of semen; the fructolysi...

Background: Chemotherapy or irradiation is associated with impaired fertility. The aim of this study was to investigate the possible protective role of testosterone enanthate (TE) on the proliferative activity, plasma testosterone level and morphometry of epithelial cells of seminal vesicles in busulfan-induced spermiotoxicity. Materials and Methods: Sprague- Dawley rats were divided into 4 gro...
