Abstract/OtherAbstract:
The potential benefits of assisted reproduction techniques, such as in vitro maturation (IVM) and in vitro fertilization (IVF) in canids, are linked to the protection and saving of species threatened by extinction due to worldwide habitat destruction and pollution. In both domestic and wild species, these technologies will form the basis for the next leap in reproductive performance by improving fertility rates in valuable middle-aged females, by improving pregnancy rate in infertile or sub-fertile populations and by rescuing biological material to replenish populations of endangered species. In vitro techniques are supposed to answer the reproductive questions of canids, to introduce new methods for contraception and to compete with artificial insemination (AI) as the major or predominant method of embryo production, oocyte- and embryo cryopreservation and cloning. The causes affecting in vitro meiosis of dog oocytes are likely to be diverse. Incomplete understanding of the events associated with oocyte developmental competence are imputed to species reproductive physiology, medium composition and source of ovarian oocyte population used for in vitro maturation. This review addresses some issues on the current state of in vitro maturation and in vitro fertilization of canine oocytes.
