Sperm Function Tests in the Stallion

چکیده

Introduction: There are many tests that describe semen quality in the stallion which include sperm motility, morphology, and longevity of motility and determination of total sperm numbers. In addition, recently, the flow cytometer (FC) has been used to evaluate various sperm compartment following staining with specific fluorescent probes that bind to different compartments of the sperm. Our lab is interested in developing sperm function tests that evaluate sperm compartments as well as determining how these tests can be applied clinically to the diagnosis of stallion subfertility. The sperm compartments that we are currently evaluating include the sperm DNA, the membrane integrity of the head and midpiece mitochondria, and the ability of the acrosome to react. The evaluation of these compartments allows the clinician additional diagnostic latitude when faced with a stallion that has a history of subfertility.

Cryobiological determinants of frozen semen quality, with special reference to stallion.

Success in cryopreserving stallion semen has been very variable. Several different freezing regimes have been published. However, because extenders and procedures used in each regime have differed, direct comparison of these techniques has been very difficult, and controlled studies comparing different techniques have not been reported. A number of different factors affect sperm cryosurvival. I...

An analysis of Selected Aspects of Sperm Quality in Fresh and Cooled-Storage Stallion Semen

This review summarises the most significant findings related to the issue of the quantitative and qualitative indicators of stallion ejaculates, its processing when producing chilled insemination doses and the possibility of influencing the individual steps of the entire process. Artificial insemination, with cooled-storage semen, is increasingly used in horse breeding because it offers many ad...

In Vitro Evaluation of Frozen-Thawed Stallion Semen: A Review

The article reviews methods used for in vitro evaluation of sperm, with particular emphasis on frozen-thawed stallion sperm. The techniques, limitations of the methods and correlations with fertility results are discussed. Very few studies have tried to find correlation between fertility of frozen stallion semen and laboratory tests. It is difficult and expensive to inseminate an adequate numbe...

A plasma membrane-associated hyaluronidase is localized to the posterior acrosomal region of stallion sperm and is associated with spermatozoal function.

Sperm hyaluronidase has been implicated in sperm penetration of the extracellular matrix of the cumulus oophorus and may play a crucial role in gamete interaction and fertility in mammals. The objectives of this study were to characterize the enzyme activity of equine sperm hyaluronidase and to investigate its cellular distribution. Zymography of stallion sperm plasma membrane extracts was used...

The Relationship Between Chromatin Quality and Fertility of Chilled Stallion Sperm

The technique (sperm chromatin structure assay) used in this study identifies one reason (a decrease in chromatin quality) for stallions whose semen shows reduced fertility when chilled. This assay is a diagnostic test, in addition to the use of sperm motility and morphologic evaluation, to evaluate the quality of chilled stallion semen and further aid the practitioner and the breeding industry...
