Genistein (GEN) and zearalenone (ZEA), environmental oestrogens commonly present in feedstuff for pigs, are known for their effects on reproductive functions. The aim was to verify the in vitro effec...
The aim of this study was to determine the effects of curcumin, ellagic acid and methionine on sperm parameters following the freeze-thawing of Merino ram semen. Ejaculates were collected via an artif...
While no cleavage was observed in the CYS group, no significant differences in the cleavage rate were observed between control (21.3%) and TX (10.5%) groups. In summary, and under our conditions, ...
Heat shock protein 70 (HSP70) is considered as a gene which affects semen quality traits. The present study attempted to investigate the relationship between the HSP70 expression level and motility of...
In this study, changes of pH, ionic (Na+, K+, Ca2+,and Mg2+), biochemical (total protein, glucose, and cholesterol)compositions of seminal plasma, sperm motility traits (percentage of motile spermatoz...
The study was conducted to evaluate the potential cryoprotective effect of butylated hydroxytoluene (BHT) through post-thaw evaluation of canine semen and its optimal inclusion level. Ejaculated can...
However, the HOS-2 and HOS-3 values in FT semen had high correlations with NRR (r = 0.65, r = 0.66, P < 0.001 at batch level and r = 0.63, r = 0.71, P < 0.01 at bull level), which was comparable t...
The mineral and organic composition of seminal plasma, physical spermatological parameters and their physiological relationships were investigated in Salmo trutta macrostigma. The seminal plasma conta...
Dynamics of sperm motility (sperm velocity, percentage of motility and flagellar beat frequency) and monthly variations of semen characteristics (semen volume and osmolality and sperm concentration an...
ABSTRACT: The goal of this study was to examine the effect of epidermal growth factor (EGF) on sperm viability using two fluorescent techniques and to analyze the obtained results in relation to sperm...
We investigated the effects of various concentrations of β-hydroxybutyrate (BHB, 0, 0.1, 1 and 10 mM), a ketone body, added to chemically-defined maturation medium with or without energy substrates (g...
An attempt to evaluate the effect of spermatozoa concentration in one ejaculate on their measurements, shape, frequency of occurrence of morphological abnormalities in spermatozoa and physical traits ...
This study examined whether chicken seminal fluid was a useful diluent for quail sperm. Both sperm motility and progressive motility, when diluted with chicken seminal fluid (90.4% and 54.6%), were si...
The present study was undertaken to evaluating the effects of diethylstilbestrol (DES) on sperm motility and reproductive function in male Japanese quail. To do so, we have identified the method that ...
The goal of this study was to determine the mechanism by which the fertility was declined by repeated artificial insemination (AI) in laying hens. The structures of sperm storage tubules (SST) and lym...
