Regarding the time of blastulation, it has been shown that the kinetics of bovine embryo development is affected by serum supplementation during IVM-IVF and embryo culture as the first and fourth cell cycles are prolonged by 4-5 hr in the absence of serum during IVM-IVF which in turn can influence the time of blastulation (12).
In our study, the time of blastulation was accelerated in FBS supplemented groups compared with those supplemented by BSA during IVM (data not shown).
Blastulation rate included all embryos not transferred on day 3 that reached blastocyst stage; no significant difference between the two groups were noted.
The proportions of cleavage, blastulation, hatching of embryos out of the total treated oocytes and the proportions of post-thaw surviving and hatching out of the total cryopreserved embryos were subjected to are sin transformation and analyzed by one-way analysis of variance.
In these results, as in the studies with chlorpyrifos alone, sea urchin embryos were relatively insensitive during cleavage divisions and blastulation, but displayed high sensitivity at the mid-blastula 2 stage.
