Although it has been proposed that the Fas and Fas ligand (FasL) may protect ejaculated spermatozoa against apoptosis induced by lipoperoxidative damage and against lymphocytes present in the female g...
Soybean lecithin-based extenders represent an alternative to extenders containing egg yolk, but there has been discussion about their cryoprotective efficacy. Low-density lipoprotein (LDL) was proved ...
The aim of this in vitro study was to determine the effect of lead chloride (PbCl2) on rabbit spermatozoa motility and morphology. Lead concentrations in the medium ranged between 0.45 and 11.17 μg/ml...
The present study is focused on the methodology of fluorescence activated cell sorting (FACS) of spermatozoa stained by the antibody against extracellular surface marker ubiquitin (eUb) and subsequent...
The effect of adding high or low protein content homologous seminal plasma to boar spermatozoa on the progressive motility of the spermatozoa after storage for three days, and at a 1 : 4 dilution rati...
The generation of hydrogen peroxide (H2O2) by ram spermatozoa (spz) was measured using a flurometric assay with 10-acetyl-3,7-dihydroxyphenoxazine agent as a probe for H2O2 detection. The kinetics of ...
This study was designed to investigate the characteristics of acrosomal changes during capacitation of bovine spermatozoa in relationship to in vitro fertility of individual bulls. Motile spermatozoa ...
Toxicity is a major limitation to successful spermatozoa cryopreservation of fish. Due to this problem, it is critical to find potential cryoprotectants which are more environmental-friendly, non-to...
It was hypothesized that sperm hypotonic exposure can provoke oxidative stress which could be involved in sperm quality degradation. Our study aimed to describe spermatozoa motility parameters and...
Oxidant and antioxidant activity in seminal plasma was compared with that in spermatozoa of teleost (common carp Cyprinus carpio and brook trout Salvelinus fontinalis) and chondrostean (Russian sturge...
The objective of this study was to provide some data on concentrations of seminal plasma free amino acids (FAAs) in order to compare these values with different total contents of morphologically abnor...
Ultraweak photon emission measurements were found to be a useful tool for investigating the influence of stress factors on cells. In the present study, induced photon emission of boar spermatozoa was ...
Sperm chromatin status in fresh dog semen and the effect of long-term storage of chilled and frozen dog semen on sperm chromatin integrity was assessed by the sperm chromatin structure assay (SCSA). I...
A good functional status of cryopreserved boar spermatozoa is very important for successful fertilization of porcine oocytes and in vitro embryo production. The purpose of the study was to evaluate th...
The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of se...
