Currently, the most widely used biotech is the collection of artificial vagina, however, as this method mimics the natural breeding, several physical, reproductive and / or behavioral preclude this method of collection. Thus, without triggering the ejaculation process it is not possible to obtain the semen, making it impossible to use these animals for breeding. Triggering neurophysiologi…
Some studies have shown that seminal vesiculitis and the plasma fraction produced by seminal vesicle leads to damage to sperm quality, causing different degrees of subfertility, and even infertility in stallions. Thus, the aims of this study include: evaluating the effectiveness of local treatment guided by endoscopy of stallions with seminal vesiculitis, and index of kinetics, morphology…
The equine species has reduced fertility rates when compared to other domestic species. Part of these observations relates to the fact that horses are not selected for fertility. In addition, there are tendencies to attribute infertility problems to the female, which compromise a detailed evaluation of the male. Among the factors that can alter the reproductive indices, sperm quality take…

Equines has low fertility when compared to other species, since the animals are selected for the athletic performance and not for their reproductive characteristics. Thus, a large number of stallions are subfertile and few treatments have been developed to improve their seminal quality. Thus, the objective of this research is to evaluate the safety and efficacy of the application of GnRH …
The use of reproductive biotechniques, especially cryopreservation of equine semen, is constantly growing. However, it needs constant improvement to increase fertility rates in some stallions that are still very low. These stallions are called as refrigeration sensitive, so there is a constant interest in the search for improvements in techniques, processes, and manipulation to raise the …
In face of the satisfactory fertility it is widely known on reproduction of equine specie the use of cooled semen. In contrast, frozen semen has barriers to surpass since not all semen is resistant to stress caused by the process of freezing. Therefore, studies are conducted aiming the acquisition of a product of better quality, minimising the damaging effects that cryopreservation causes…
After spermatogenesis, the sperm is unable to fertilize the oocyte. Significant changes occur on membrane domains and on functionality of the sperm cell during epididymal maturation, offering these cells fertilizing capacity, and such steps occur in complete absence of gene expression. Thus, sperm kinetic parameters, apoptosis index, production of reactive oxygen species (ROS) and lipid p…

The equine species has low fertility when compared to other species, since the animals are selected for their athletic performance and not for their reproductive characteristics. Thus, a large number of stallions present subfertility and few treatments have been developed to improve the seminal quality of these animals. Besides, in valuable stallionseven slight decreases in reproductive e…
Androgen receptors (ARs) and estrogen receptors (ER-± and ER-ß) are important in male reproductive tract biology such as in the regulation of factors that maintain spermatogenesis and ensure the production of a physiological environment for sperm maturation. Thus the immunohistochemistry evaluation of the expression of these steroid receptors is critical to evaluate the functionality of t…
