The use of biotechnologies in equine reproduction has advanced exponentially, driven by thedemand for genetic improvement of animals with high zootechnical value. Among thesetechnologies, in vitro fertilization (IVF) in horses remains challenging, with consistently lowsuccess rates reported over the past decades. This limited performance is directly associatedwith the peculiarities of equ…
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…

The use of biotechnology in equine reproduction has experienced exponential growth, driven by the search for the genetic improvement of animals with high zootechnical value. The technique of in vitro fertilization (IVF) in horses has been tested, showing persistently low success rates over decades. This complexity is intrinsically related to injuries to equine sperm during the in vitro sp…
The biotechnology for freezing equine semen has evolved a lot in the last two decades and, as a result, some stallions that were unable to pass the freezing test became part of this group, increasing the number of animals that can store genetic material through cryopreservation, mainly for those animals that are temporarily or permanently unable to be used in animal reproduction.The techn…
Many researches have been carried out with the objective of enabling the use of cryoprotectants that could provide a lower osmotic shock during cryopreservation of equine spermatozoa. There is a large amount of studies focused on testing different types of cryoprotectants in various concentrations and associations, which are used in equine semen freezing diluents. However, the results of …
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 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…
