TL;DR: Sperm concentration and sperm membrane intactness (SMI) or viability are two measures of sperm quality that provide important but different information about a stallion's reproductive capability.

TL;DR: The Slc10a6-/- knockout mice were fertile, produced normal litter sizes, and had normal spermatogenesis and sperm vitality, suggesting that the loss of Soat can be compensated in the knockout mice or that Soat function is not essential for reproduction.

TL;DR: The results indicate that meiosis in GV-stage horse oocytes having condensed chromatin may be suppressed by inhibitors of m-phase protein activity; however, oocytes originally having diffuse chromatin appear to degenerate in culture even in the presence of these inhibitors.

TL;DR: The relationship among sperm attributes of DNA integrity, sperm motility, morphology, viability, acrosome integrity and in vivo fertility of frozen-thawed Italian Mediterranean Buffalo sperm has not been reported and among sperm features analyzed the area under the Receiver Operating Characteristic (ROC) Curve was significant in estimating pregnancy.

TL;DR: Stallion semen evaluation is an important part of the breeding soundness evaluation and any sperm quality test must be interpreted with a clear understanding of how it relates to fertility.
