PURPOSE We assessed the frequency of azoospermia factor a (AZFa), AZFb, and AZFc deletions and examined correlations between the deletion sites and the success rates of sperm presence within the ejaculate and surgical sperm retrieval in Korean men. MATERIALS AND METHODS A total of 1,919 azoospermic and severely oligozoospermic men were assessed for Y chromosome microdeletions. Among them, 168...

Brazil is the second country on equine embryo world production. Problems related to the application of equine embryos transfer in Brazil are discussed in this article. The main factor related to low efficacy of Equine Embryos Transfer programs consists in the difficulty to induce multiple ovulations Among the most common difficulties and limitations faced in our country, we emphasize the utiliz...

Equine epizootics of Venezuelan equine encephalitis (VEE) occurred in the southern Mexican states of Chiapas in 1993 and Oaxaca in 1996. To assess the impact of continuing circulation of VEE virus (VEEV) on human and animal populations, serologic and viral isolation studies were conducted in 2000 to 2001 in Chiapas State. Human serosurveys and risk analyses indicated that long-term endemic tran...

providing suitable analgesia following diagnostic and therapeutic arthroscopic surgeries, that areconsidered to cause some degree of postoperative pain, is a necessity in equine practice. the aim of thepresent study was to evaluate the equine synovial fluid biochemical and cytological changes as well asclinical assessments of the joint following intra-articular administration of ketamine. six a...

A detailed examination of the cardiac system is essential to a complete physical examination of horses. An understanding of the peculiarities of cardiac auscultation in horses is important in this evaluation. These peculiarities are associated with the large gauge of the equine central cardiac system and high vagal tone. Author’s address: Idaho Equine Hospital, 16080 Equine Dr, Nampa, Idaho 836...

BACKGROUND Quantitative information about equine mortality is relatively scarce, yet it could be of great value for epidemiological purposes. In France, data from rendering plants are centralised in the Fallen Stock Data Interchange database (FSDI), managed by the French Ministry of Agriculture, while individual equine data are centralised in the French equine census database, SIRE, managed by ...

BACKGROUND The aim of the present study was to investigate the efficacy of the Improvac on testosterone concentration in blood serum, sexual behavior and sperm quality in matured AI boars. A total of nine Danish Landrace AI boars were included in the analysis. METHODS The trial period lasted for 15 weeks and was divided into four periods: Control period: three weeks before vaccination; Period...

BACKGROUND ICSI into the oocyte is the only treatment currently available for most male patients with severe oligozoospermia who wish to father children. In order to perform ICSI, motile sperm need to be recovered from the ejaculate and, if no sperm or not enough motile sperm are recovered on the day of ICSI, testicular sperm extraction (TESE) must be performed. Oxytocin stimulates epididymal c...

Insect genitalia exhibit rapid divergent evolution. Truly extraordinary structures have evolved in some groups, presumably as a result of postmating sexual selection. To increase our understanding of this phenomenon, we studied the function of one such structure. The male genitalia of Callosobruchus subinnotatus (Coleoptera: Bruchinae) contain a pair of jaw-like structures with unknown function...
