El proceso reproductivo de los animales requiere de la energía que se obtiene de los alimentos. Sin embargo, en ellos también pueden estar presentes compuestos que interfieren potencialmente con la fisiología y control de la reproducción. Tal es el caso de los fitoestrógenos, compuestos de origen vegetal estructuralmente similares a...
When the freezing is used as a mean of seminal preservation, the viscosity is one characteristic not very well studied. It is considered that the natural semen’s viscosity is related to the sperm conservation. Therefore, the mean goal was to determine the effect of the viscosity of the seminal conservation...
Nowadays, amphibians have shown worldwide deterioration in their populations. In Mexico, the axolotl in an endemic species that has been affected. The International Union for the Conservation of Nature says that it should be priority and essential in genetic material cryopreservation. This study’s aim was to determine spermatic characteristics of...
Se conoce poco sobre los mecanismos específicos implicados en la capacidad de almacenamiento espermático, la cual se propone puede estar relacionada con actividad metabólica espermática y liberación controlada de los espermatozoides al lumen oviductal. Se sugiere que las microvellosidades de los túbulos almacenadores de espermatozoides presentes en la unión útero...
The objective of this research was to determine the capacitation indicators and acrosome reaction in sperm of Harris hawk (Parabuteo unicinctus) in freshly ejaculates and cryopreserved with dimethylsulfoxide (DMSO) and glicerol, as well as the parameters of viability, motility and morphology in each treatment. Heterologous perivitelline layer was implemented as...
