[EN] The efficiency of an embryo bank depends on provision of optimal conditions for recovery, cryopreservation and transfer to a breed or strain. In this sense, increasing the number of embryos available using superovulation ...

[EN] Superovulatory treatments allow higher oocyte and embryo recovery rates, decreasing costs and allowing the improvement and development of reproductive and genetic tools. However, those treatments present limitations ...

[EN] Preimplantation embryo manipulations during standard assisted reproductive technologies (ART) have significant repercussions on offspring. However, few studies to date have investigated the potential long-term outcomes ...

En este trabajo de tesis, se presentan diversos estudios experimentales, desarrollados prin cipalmente en pez cebra pero también en ostra del Pacífico, que persiguen la puesta a punto de técnicas relevantes para la utilización ...

[EN] The assisted reproductive technologies (ART) are increasingly used. However, in the last years, several studies have demonstrated the harmful effects associated with ART. There are more and more epigenetic studies ...

La producción de embriones mediante la recuperación de ovocitos inmaduros por ovum pick up (OPU), y su posterior maduración, fecundación y cultivo en el laboratorio in vitro, presenta numerosos beneficios para optimizar ...

[EN] The sexual receptivity and ovulation induction of the reproductive rabbit are key points determining their success in productive life. Adequate synchronisation of the sexual receptivity methods of inseminated rabbit ...

Parthenogenetic embryos are one attractive alternative as a source of embryonic stem cells, although many aspects related to the biology of parthenogenetic embryos and parthenogenetically derived cell lines still need to ...
