Reproductive processes involve complex and finely orchestrated events that allow for the maintenance and propagation of species. Currently, scientific and technological advances allow research to be conducted globally, which may represent a revolution in the understanding of the mechanisms involved in these processes. In addition to elucidating the key events of these processes, there may…

In vitro production (IVP) of bovine embryos is an important technology of animal reproduction. This technology is applied on research and livestock, with economic highlights. Despite its applicability, the efficiency of IVP is considered limited when compared to the in vivo process. The effect of sperm in embryonic development has been described but it is not clear yet which attributes di…
Oxidative status may influence spermatozoa by distinct mechanisms, from capacitation to oocyte fertilization. However, reactive oxygen species (ROS) could be beneficial or harmful depending on cellular context. Due to the low levels of antioxidant enzymes of cryopreserved semen, associated to successive manipulations prior to in vitro fertilization (IVF), it is momentous to understand the…

Aging is a phenomenon that profoundly influences organismal biology, with significant implications for reproductive health. While senescence in female fertility has garnered greater attention, the impact of aging on males and sperm cells is equally critical. With advancing age, sperm structure and functionality are compromised, adversely affecting both the early and later developmental st…
In vitro production of bovine embryos (PIVE) is an important tool inanimal reproduction, with academic and commercial applications and with great relevanceeconomic. Despite its applicability, the efficiency of PIVE is considered limitedwhen compared to the in vivo process. The effect of sperm onembryonic development has already been described, but it is still unclear whether they are thes…
n vitro production of bovine embryos (IVP) is a reproductive biotechnique that aims to improve bovine production and is of extreme economic relevance, being one of the most widely used biotechniques for animal genetic improvement in Brazil. Recent studies report the paternal contribution in situations of defective fertilization and abnormal embryogenesis within IVP. Incorporated into thes…
In the last years scientists has carry out studies about the effects of age on women reproductive performance, however few studies analyze male reproductive efficiency and age. Increased paternal age has been associated with the development of several disorders, neurological and metabolic, such as schizophrenia, autism, bipolar disorders, cancers. Reproductive disorders such as decreased …
Currently the spermatozoa is no longer known only as a cell that delivers the male genetic material to the oocyte, since it provides fundamental factors for fertilization and embryonic development. We can include microRNAs (miRNAs) as one of these factors. MiRNAs are small RNAs that do not encode proteins but modulate gene expression and are present in spermatozoa. It is known that these …

With climate change, fires, floods, global warming are part of our daily lives. One of the factors responsible for the situation in which the world finds itself, pointed out at COP26 in Glasgow last month, is livestock. However, it is not enough to blame a sector and demand that the consumer no longer eat meat, especially beef. It is necessary for each sector to think about solutions and …
The mature spermatozoa present a unique chromatin compaction that allows the protection of paternal DNA during the route until the oocyte. This high degree of compaction is characterized by protamine-DNA binding, the nuclear protein that replaces histone during spermatogenesis. However, some specific regions of the sperm chromatin remain bound to nucleosomes composed of histones. In human…
The ram's sperm is very susceptible to injuries due to the processes of reproductive biotechnologies. This sensibility can be a consequence of the balance between reactive oxygen species and antioxidants instability present in seminal plasma leading to the oxidative stress. The oxidative stress can provoke DNA damage. The result of this process cause sperm vulnerability, which start the a…
