Sperm Flagellum Volume Determines Freezability in Red Deer Spermatozoa
The factors affecting the inter-individual differences in sperm freezability is a major line of research in spermatology. Poor sperm freezability is mainly characterised by a low sperm velocity, which in turn is associated with low fertility rates in most animal species. Studies concerning the implications of sperm morphometry on freezability are quite limited, and most of them are based on spe...
متن کاملStudy of Bull Spermatozoa
The electron microscope has been used to determine the characteristic dimensions and the distribution of the dry mass in bull spermatozoa. The most important result is that all characteristic data are occurring in logarithmic distributions. Furthermore, no correlation between such parameters as head weight and tail weight or head length and tail length was found. The occurrence in logarithmic d...
متن کاملLeptin Receptor in Ram Epididymal Spermatozoa
This experiment was designed to investigate leptin receptors (Ob-R and Ob-Rb) mRNA in ram epididymal spermatozoa by RT-PCR. Ten testes were obtained from abattoir and epididymal spermatozoa recovery was performed. To purify spermatozoa, motile sperm were isolated by the swim-up procedure. Total RNA was isolated from epididymal spermatozoa and placental cotyledon, as a positive control, and then...
متن کاملStudies on the Freezability of Kundhi Buffalo Bull Semen
This study was conducted to assess the post thaw quality of Kundhi buffalo semen diluted in tris based diluents. After collection the ejaculates were pooled and checked for color, volume, pH, mass activity, progressive linear motility% (PLM), and intactness of cell membrane. The semen qualifying these tests was divided into four aliquots A, B, C and D, diluted with tris based diluents; the last...
متن کاملThe Morphology of Bull Spermatozoa
It has been known since the nineteenth century that the microscopical structure of living cells may be modified by fixation and by post-mortem or sub-mortem changes (Hardy, 1899), but inadequate attention seems to have been paid to factors which may injure spermatozoa before fixation and microscopical examination. One such factor is the effect of sudden cooling. If semen is exposed to a sudden ...
