15 صفحه اولMotility of spermatozoa at surfaces.
The hydrodynamic basis for the accumulation of spermatozoa at surfaces has been investigated. The general conclusion is that when spermatozoa arrive at a surface, they will remain there if the vector of the time-averaged thrust is directed towards that surface. This can arise in two basic ways. First, consider spermatozoa that maintain a three-dimensional waveform and roll (spin) as they progre...
متن کاملMotility evaluation of human spermatozoa
In this contribution we investigate the applicability of photon correlation techniques as a clinical tool for the evaluation of motility parameters of undiluted human sperm. Measurements on semen samples, selected visually for 'good' motility, yielded reproducible estimates of the fraction motile spermatozoa and the mean speed of the motile cells.
متن کاملFormation of Hydrogen Peroxide by Chilled Goat Spermatozoa and the Effects of Dead Spermatozoa on Motility Characteristics
In this study, the formation of hydrogen peroxide (H2O2) by chilled goat spermatozoa was measured. Furthermore, the effects of dead spermatozoa on motility characteristics were studied. Fresh collected ejaculates from five Shami bucks were centrifuged and virtually all seminal plasma was removed. A part of the collected spermatozoa was killed by two ways: the first by repe...
متن کاملDeleterious actions of gossypol on bovine spermatozoa, oocytes, and embryos.
Gossypol (50 and 100 micrograms/ml) decreased the percentage of sperm that completed the swim-up procedure. This effect was not blocked by glutathione monoethyl ester. Cleavage rates were not different between oocytes inseminated with gossypol-treated spermatozoa (10 or 50 micrograms/ml) and oocytes inseminated with control spermatozoa. Development to the blastocyst stage at Day 7 after insemin...
