Within 40 s the Sperm Quality Analyzer (United Medical Systems, Santa Ana, CA, USA) provides a numerical value called the sperm motility index. This index reflects both the concentration of motile sperm cells and the intensity of their motility and cannot be determined by conventional semen analysis.

Assessment of an iPad-based sperm motility analyzer for determination of canine sperm motility [PDF]
Abstract The objective of this study was to evaluate the repeatability and accuracy of canine sperm motility (total and progressive) assessment with a tablet-based Canine iSperm instrument compared to computer-assisted sperm analysis (CASA).

Transcriptome analysis of the testes of male chickens with high and low sperm motility
: The reproductive performance of chicken breeders has significant economic importance in the poultry industry, and sperm motility is an indicator of reproductive performance. This study performed RNA-seq of the testes of Gushi chicken roosters with high

Size dependent inhibition of sperm motility by copper particles as a path towards reversible male contraception [PDF]
Effective inhibition of sperm motility using a spermicide can be a promising approach in developing non-invasive male contraceptive agents. Copper is known to have contraceptive properties and has been used clinically for decades as intrauterine ...

Seawater carbonate chemistry and sperm motility of Tegillarca granosavia [PDF]
Since the industrial revolution, massive amount of anthropogenic carbon dioxide (CO2) have been generated to elevate the atmospheric CO2 concentration. Some anthropogenic CO2 have been absorbed by the ocean to cause “ocean acidification” (OA).

Cryopreservation of common carp sperm [PDF]
Experiments were carried out to investigate the effect of five extenders (sucrose, glucose, fructose, KCl and a saline carp sperm extender) and two cryoprotectants (dimethyl-sulfoxide (DMSO) and methanol) on the cryopreservation of common carp sperm ...

Plasma membrane Ca2+ ATPase 4 is required for sperm motility and male fertility [PDF]
Calcium and Ca(2+)-dependent signals play a crucial role in sperm motility and mammalian fertilization, but the molecules and mechanisms underlying these Ca(2+)-dependent pathways are incompletely understood. Here we show that homozygous male mice with a

Post-Meiotic Intra-Testicular Sperm Senescence in a Wild Vertebrate [PDF]
There is growing interest in sperm senescence, both in its underlying mechanisms and evolutionary consequences, because it can impact the evolution of numerous life history traits. Previous studies have documented various types of sperm senescence, but
