Foster, Mary L. (2010-07-14)Assessment of sperm viability is an important component for evaluating stallion sperm quality. The flow cytometer is considered the standard in the assessment of sperm plasma membrane integrity (viability); however, ...

Cushioned centrifugation of stallion semen: factors impacting equine sperm recovery rate and quality Waite, Jessica Arlene (2009-05-15)Centrifugation of stallion semen is an integral part of the cryopreservation procedure, primarily allowing for the concentration of sperm and removal of seminal plasma. In addition, centrifugation is required for maximizing ...

Paria, Nandina (2012-02-14)The genetic component of mammalian male fertility is complex and involves thousands of genes. The majority of these genes are distributed on autosomes and the X chromosome, while a small number are located on the Y chromosome. ...

Salazar, Jose L. (2010-10-12)Three ejaculates from each of eight stallions were initially centrifuged in INRA 96 extender and spermatozoal pellets were resuspended in a milk/egg yolk-based freezing extender or an egg yolk-based freezing extender. ...

Edmond, Ann J. (2010-07-14)Density gradient centrifugation of sperm is a common assisted-reproduction procedure in humans used to improve semen quality. The technique allows sperm separation based on their isopycnic points. Sperm with morphologic ...

Bosard, Tegan S. (2009-06-02)The objective of this study was to establish a rapid and efficient assay that would assess acrosomal status and function of the stallion acrosome. Ejaculates from fertile and subfertile stallions were extended to 25x106/mL ...

Laughlin, Andy M. (2011-08-08)Understanding the genes that regulate spermatogenesis and steroidogenesis in the testis is critical for enhancement of stallion fertility. Stallion testicular samples were used to identify candidate genes by cDNA microarrays ...

Heninger, Noah Leland, III (Texas A&M University, 2007-04-25)Apoptosis in testicular germ cells has been demonstrated in many species. Features of apoptosis reported in other species were used to confirm use of the TUNEL assay in stallion testes. Eight stallions with normal testicular ...
