Infertility is a major reproductive and social problem with a worldwide prevalence of 10-15%. While 11.8-39.0% of infertility cases are attributable to the female, 15.8-42.4% is attributed to the male and 8.0-11.1% to unknown factors. The study investigated the efficacy of the single versus combined regimes of antioxidant vitamins C and E oral supplements on sperm motility in the reproductively...

Aim: The present study was carried out to examine the relationships among frozen-thawed semen fertility, physical parameters, seminal quality, and testosterone concentration in Murrah buffalo bulls. Materials and Methods: A total of 30 breeding Murrah buffalo bulls (either progeny tested or under progeny testing program) were randomly selected from two government bull farms in Punjab. None of t...

BACKGROUND The vitamin D receptor (VDR) is expressed in human spermatozoa, and VDR-knockout mice and vitamin D (VD) deficiency in rodents results in impaired fertility, low sperm counts and a low number of motile spermatozoa. We investigated the role of activated VD (1,25(OH)(2)D(3)) in human spermatozoa and whether VD serum levels are associated with semen quality. METHODS Cross-sectional as...

A morphological, biochemical and physiological study has been made of the effects of chloroquine-diphosphate (a membrane stabilizer) on the preservation of buffalo spermatozoa in five modified dilutors designated here as Al’ A2’ A3, A4 and CAW. In almost all the five dilutors, there was significant (p< 0.01) progressive increase in the percentage of sperm abnormalities and the release of enzyme...

The Radio Electric Asymmetric Conveyer (REAC) has been mostly applied to treat symptoms related to psychological stress. In the study, we demonstrated the effect of REAC-Veterinary Neuro Psycho Physical Optimization (VNPPO) treatment protocol on sperm parameters of subfertile (n=11) and fertile (n=4) stallions. Subfertile stallions showed a reduced sperm concentration, progressive motility and ...

Gastrointestinal motility and plasma PYY levels were investigated under chronic progressive large bowel obstruction in dogs. The obstruction device was applied around the descending colon at a laparotomy and gastrointestinal motility was recorded with strain gauge force transducers in the conscious state. Complete obstruction occurred at 26 days (21-33 days). The duration of postprandial interr...

BACKGROUND Amyotrophic lateral sclerosis (ALS)-Plus syndromes meet clinical criteria for ALS but also include 1 or more additional features such as dementia, geographic clustering, extrapyramidal signs, objective sensory loss, autonomic dysfunction, cerebellar degeneration, or ocular motility disturbance. METHODS We performed a whole-brain and spinal cord pathologic analysis in a patient with...

Concentrations of mono- and divalent cations in the testis, three different regions of the epididymis and the vas deferens of lizard, M. carinata were determined. The concentrations of Na+, K+ and Ca2+ increased gradually from testis to vas deferens. However, no significant variation in the levels of Mg2+ was observed between testis and anterior epididymis, and between posterior epididymis and ...

Serum follicle stimulating hormone (FSH) is routinely measured when evaluating the infertile male for intracytoplasmic sperm injection (ICSI). However, among the sperm parameters, only its relationship with sperm concentration is well documented. Few investigations concern the relationship between FSH and sperm motility and morphology, and the results of ICSI. A retrospective study of 316 coupl...

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 o...
