چکیده
The aim of the present study was to evaluate the effects of different seasons on the morphometric testicular parameters and the respective epididymal sperm parameters. Total numbers of 104 scrota of pubertal buffalo bull (24-48 months) include their contents were provided from the local slaughterhouse. Scrotal circumference was measured on its place before dissection. Morphological parameters of testis and epididymis and epididymal sperm were analyzed. The results showed the highest scrotal circumference and testicular weight as well as retrieved sperm concentrations in spring. However, sperm tail and midpiece abnormalities were highest and the sperm progressive motility was the lowest during spring. During summer the lowest testicular weight and retrieved sperm concentration as well as low sperm progressive motility was considered. In conclusion, the results of the present study confirm direct influence of different seasons on the epididymal sperm and the testicular parameters of the Iranian river buffalo bull.

Cryopreservation of in situ cool stored buffalo (Bubalus bubalis) epididymal sperm
The objectives of this study were to investigate the effects of testis-epididymis cool storage on viability and progressive motility of buffalo epididymal sperm (EP) and to compare the influences of two basic semen extenders on post thaw EP viability and progressive motility. Abattoir collected buffalo testicles were allotted to three storage times (0 h: n = 10; 24 h: n = 10 and 48 h: n = 12). ...

Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...

Background: Artificial insemination is a valuable tool in genetic improvement programs and widely used breeding technique in farm animals. Semen processing and cryopreservation causes considerable damage to sperm DNA, motility apparatus, plasma membrane, acrosomal cap and thus, reduced fertility. Selenium is an integral part of glutathione peroxidase (GSH-Px), an enzyme which protects cell inte...

The aim of the present study was to investigate the effect of in vitro supplementation of selenium on fresh and frozen spermatozoa quality of buffalo (Bubalus bubalis) bulls. Five healthy buffalo bulls (5 ejaculates from each bull) were used. Each ejaculate was diluted at 37 ˚C with tris-based extender containing 0 (control), 0.5, 1, 2, 4 and 8 μg mL-1 sodium selenite and the sperm motility and...

Background: There is a considerable numbers of buffalo (Bubalus bubalis) in Iran which have an important role in rural life. The reproductive performance of buffalo is lower than cow. Co-culture with somatice cells improved the maturation rate of most of the species. The aim of the present study was to evaluate the effect of bovine cumulus co-culture on post fertilization development of buffalo...
