Abstract:

Use of quality sires in the artificial insemination of cattle leads to the increased production in cattle breeding. In EU countries and the countries which cooperate in semen trade with EU countries bulls? health status and minimal criteria for semen quality are regulated by law. Bull semen quality is influenced by several exogenous factors. Semen quality parameters are influenced by season. The highest values of ejaculate volume and total sperm output were found during the summer, while the lowest values were found in winter period. Some xenobiotics can also affect semen parameters.

Abstract:

Thyroid hormones and their impacts on male reproduction have been reported in numerous studies in past few decades. They are the crucial players in the regulation of male gonadal developments and reproductive functions. An excess or deficit of thyroid hormones not only alter the testicular functions but also interrupts neuroendocrine axis through the crosstalk between hypothalamic-pituitary-thyroid (HPT) axis and hypothalamic-pituitary-gonadal (HPG) axis. These changes result in decreased testosterone level and altered seminal plasma components which affect semen quality. The reports on the di

The purpose of this study was to examine sperm quality after cryopreservation of ejaculates collected as a bulk sample, which is routinely part of semen collection, and to compare this quality with the sperm-rich fraction in boars. Ejaculates were collected as sperm-rich fractions (SRF) and bulk samples (BE) using a gloved-hand technique. Fresh semen quality in terms of semen volume, sperm concentration, total sperm motility and pH were conventionally evaluated. Then, semen was cryopreserved using the liquid nitrogen vapour method.

AbstractSince the end of the last century, several reports have suggested that semen quality is declining, especially in Western countries. Furthermore, cross-sectional studies using similar protocols have suggested regional differences in semen quality of young and fertile men. Reasons for these regional differences and local adverse trends in semen quality are unknown, but environmental factors are suspected to have a role. Besides adulthood environmental exposures, those occurring during testicular development may also affect semen quality. Longitudinal follow-up studies and mixture risk an

Thyroid hormones act on testis in multiple ways and exert their effect on different cell types, including Leydig and Sertoli cells, and germ cells. An excess or deficit of thyroid hormones results in alterations of testis function, including semen abnormalities. More frequently, hyperthyroidism has been associated with reduced semen volume and reduced sperm density, motility, and morphology, whereas hypothyroidism is associated with reduced sperm morphology. Therefore, thyroid function tests should be part of the diagnostic workup of the infertile man. This article is aimed at (1) elucidating

Recent advances in artificial insemination (AI) and semen preparation have led to an increase in the availability of equine genetics globally. Generally, less than half the stallion population produce semen of suitable robustness to maintain acceptable fertility post-freezing, and research is needed to improve not only the numbers of stallions whose semen can be successfully frozen, but also to increase the number of collections that meet fertility standards. The number of progressively motile sperm present during ovulation determines successful conception in horses. AI practitioners recommend

There is increasing evidence from non-human animals that males adjust their ejaculate expenditure according to the risk of sperm competition. In this study we show that, after controlling for lifestyle factors known to influence semen quality, human males viewing images depicting sperm competition had a higher percentage of motile sperm in their ejaculates. Many lifestyle variables were confirmed to influence semen quality, including the recent suggestion that storage of mobile phones close to the testes can decrease semen quality.

Abstract:

Abstract Semen used for artificial insemination (AI) in the swine industry is typically collected into a warmed semen collection cup containing an empty collection bag. If the ambient temperature does not closely match the temperature of the warmed collection cup and semen at the time of collection then negative effects to the motility and morphology of the sperm cells may occur due to temperature shock. The purpose of this research was to determine if collecting boar semen directly into semen extender warmed to 38.5°C would affect sperm quality post-collection. Sexually mature Berkshire x Dur

Abstract:

This study determines the effect of different commercial diluents on the quality of frozen Simmental semen. The extraction of fresh semen from 3 Simmental bulls using an artificial vaginal method was performed twice a week. Fresh semen with motility of >70% was further processed to frozen using a one-step dilution method, and the commercial diluents used were Andromed®, Optixcell®, and Steridyl®. The diluted semen was packed into mini-straws, equilibrated, frozen, and stored for further testing. Data were analyzed by analysis of variance (ANOVA), followed by Duncan Multiple Range Test (DMRT
