Evaluation of a portable device for assessment of motility in stallion semen.

In horse breeding, quality assessment of semen before insemination is often requested. Non-laboratory-based techniques for objective analysis of sperm motility are thus of interest. The aim of this st...

Seminal plasma proteins and their relationship with sperm motility and morphology in boars.

The identification of biomarkers associated with seminal traits could aid in the selection of higher quality ejaculates and benefit the swine industry. The objective of this study was to identify boar...

Impact of selenium nano-particles in semen extender on bull sperm quality after cryopreservation.

The aim of this study was to evaluate the effect of adding different concentrations of selenium nano-particles (Se-NPs) in semen extender on bull sperm cryopreservation. Five healthy, fertile Friesian...

Positive association of low-level environmental phthalate exposure with sperm motility was mediated by DNA methylation: A pilot study.

Accumulating evidence indicates that phthalate exposures may affect human semen quality. Epigenetic modifications such as DNA methylation might be linked chemical exposure and spermatogenesis epigenet...

Seasonal changes in the proteome of cryopreserved bull semen supernatant.

Seasonal variability in cattle fertility may be attributed to male reproduction, including the quality of semen produced by males and its usefulness after cryopreservation. The exact molecular mechani...

Medical and Biotech [MESH] Definitions

The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.

A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.

A condition of suboptimal concentration of SPERMATOZOA in the ejaculated SEMEN to ensure successful FERTILIZATION of an OVUM. In humans, oligospermia is defined as a sperm count below 20 million per milliliter semen.

Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.

Centers for acquiring and storing semen.
