Objective: The glucose-reducing effects of troxerutin was previously proven. This study was conducted to evaluate troxerutin effect on testicular structure and spermatozoid parameters in type-1 diabetic adult male rats. Materials and Methods: Fifty male Wistar rats were randomly clas...

We propose a novel classification method to identify boar spermatozoid heads which present an intracellular intensity distribution similar to a model. From semen sample images, head images are isolated and normalized. We define a model intensity distribution averaging a set of head images assumed as normal by veterinary experts. Two training sets are also formed: one with images that are simila...

studies represent that bacterial infection of the semen can have a direct role in spermatozoid parameters change and may result in men's infertility. in the present study 160 semens were examines for bacterial infection. 55(34.4%) were infected by different species of bacteria, but those infected only by 4 species were undertaken for further study.these bacteria were streptococci pyogen, entroc...

Background: The present study was conducted to investigate the effects of dietary fat sources on reproductive performance of mature rams. Materials and Methods: Twelve adult rams, with 32 months of age and a mean weight value of 67 kg, were divided into four dietary treatments using a completely randomized design. Dietary treatments included with the study were: 1. ration with 4% soybean oil (A...

The ultrastructure of spermatogenesis in Equisetum is described with particular reference to the origin and development of the multilayered structure (MLS) and nuclear metamorphosis. Simultaneously with the formation of centrioles, by the fragmentation of the blepharoplast, in young spermatids, the MLS appears in their vicinity. This comprises 4 layers recalling the Vierergruppe of bryophyte sp...

the pollution of aquatic ecosystems may affect natural reproduction of fish populations by decreasing the fertilization efficiency. among the various sources of pollution, heavy metals are important group, being found in both freshwater and marine environment. the present study investigated changes of sperm characteristics of caspimyzon wagneri when exposed to manganese (mn). spermatozoids were...

The guinea pig spermatozoid nucleus contains actin, myosin, spectrin and cytokeratin. Also, it has been reported that phalloidin and/or 2,3-butanedione monoxime retard the sperm nuclear decondensation caused by heparin, suggesting a role for F-actin and myosin in nuclear stability. The presence of an F-actin/myosin dynamic system in these nuclei led us to search for proteins usually related to ...

BACKGROUND Male infertility is a common and complex problem and, despite much research in this field, the major cause of infertility unfortunately remains unknown. Genital infection and varicocele are important causes of infertility. AIMS To compare the influence of genital infection and varicocele individually on male infertility based on semen analysis. STUDY DESIGN Cross-sectional study....

Activities of total lactate dehydrogenase, which plays an important role in providing energy for cell metabolism, lactate dehydrogenase-X, an isoenzyme of lactate dehydrogenase supposed to be specific for germinal epithelium activity, diluted semen absorbance and some other properties have been measured in 51 seminal plasma samples. Aiming to study its clinical use as a marker of seminiferous e...
