The effects of a simple saline solution prepared using two different pH (4.4 and 8.5) on sperm motility in burbot were investigated. Results were recorded during a 96-hour chilled storage (4°C) in 24-...
The aim of this study was to evaluate the effect of different thawing protocols (slow (P1), medium (P2), and fast (P3)) on percentage of motile sperm (MOT) and percentage of sperm cells with intact me...
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...
Morphological examination of spermatozoa remains a valuable tool for determining the quality of feline sperm for cryopreservation and/or for use in artificial insemination. Numerous staining technique...
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...
Context: Air pollution is common in all countries and affects reproductive functions in men and women. It particularly impacts sperm parameters in men. This meta-analysis aimed to examine the impact o...
We examined the relationships between a number of sperm characteristics (motility, concentration and pH) and sperm fertility (egg fertilisation and hatching rate) in 10 mature females and four mature ...
It is a known fact that neem oil has some effect on motility of sperm. Motility of sperm depends on mitochondrial activity present in mid-piece of sperm. In the present study, the mitochondrial activi...
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...
Spermatozoa morphology, ultrastructure, and spermatozoa motility traits were studied in pikeperch (Sander lucioperca) after activation in various media (AM 1 ?45mM NaCl, 5mM KCl, 20mM Tris, pH 8.5; AM...
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...
