[EN] The development of powerful software has made possible spermatozoa morphology studies. However, some problems have emerged in relation to protocol standardization to compare results from different laboratories. This ...

[EN] This study was conducted to elucidate the effect of different freezing extenders on two lines selected for hyperprolificacy and longevity (H and LP, respectively). In extender A, dimethyl sulphoxide (Me2SO) and sucrose ...

[EN] Contents Sperm cryopreservation is a useful tool in captive fish reproduction management, that is to synchronize gamete production, especially in the case of species as the European eel, where the time of female ...

[EN] This paper contains recommendations for procedures to be used in applied reproduction trials performed with rabbit bucks and/or semen. The factors influencing sperm production (environment, age, health status and ...

[ES] Entre los componentes del plasma seminal se encuentran las vesículas extracelulares (VEs). Son producidas tanto por el epitelio del epidídimo como por las glándulas accesorias. El contenido y función de las VEs está ...

The conservation status of the species studied in this thesis (European eel and pufferfish) is currently frail, thus the main goal of this research was to develop, improve and apply several techniques and protocols ...

[EN] The first goal of this study was the development of a short-term storage method for pufferfish (Takifugu niphobles) sperm. In this respect, the best results were obtained by diluting the sperm in a seminal-like solution ...

[EN] In rabbits, the number of inseminated spermatozoa plays an important role in the fertility rate obtained after artificial insemination. However, methods for the correct determination of spermatozoa number are scarce. ...
