Factors that interfere with oocyte quality for in vitro production of cattle embryos: Effects of different developmental & reproductive stages
(2016-01-01)
The success of IVP is ultimately dependent on the number and quality of the cumulus-oocyte complexes (COC) harvested during the OPU procedure. Several factors appear to be critical to oocyte quality including follicle size, ...
Relationship between follicle size and ultrasound-guided transvaginal oocyte recovery
(Elsevier B.V., 2001-07-03)
We evaluated the relationship between follicle size and oocyte recovery (OR) using ultrasound-guided follicle aspiration. Thirty Holstein cows were subjected to OR without gonadotrophic therapy. Oocytes were recovered two ...
