The general aim of this thesis was to optimise the current methodologies of
oocyte cryopreservation in order to obtain live offspring from cryopreserved
rabbit oocytes.
In chapter 1, meiotic spindle configuration, ...
[EN] Maize represents a staple food crop and is the second most important agricultural commodity globally. Considering the important role of maize for food security, the long-term

The short-term effects of cryopreservation and embryo transfer are well documented (reduced embryo viability, changes in pattern expression), but little is known about their long-term effects. We examined the possibility ...
[EN] Although assisted reproduction technologies (ARTs) are recognised as safe, and most of the offspring seem apparently healthy, there is clear evidence that ARTs are associated with changes in the embryo's developmental ...
