The aim of the present study was to find more parameters to define developmental competence of cumulus-oocyte-complexes (COCs). Bovine COCs were divided into five groups based on their morphology. In order of increasing level of atresia: COC-A had a

Information on the developmental potential of in vitro-produced, cryopreserved bovine embryos following single-embryo transfer to synchronized recipients is limited. The aim of this study was to compare the pregnancy rates of vitrified, conventionall

The efficacy of transvaginal ultrasound-guided puncturing of ovarian follicles for collecting immature oocytes in cattle was studied. Three experiments were conducted to examine the effects of puncturing on follicle recruitment and on the number of o

The aim of this study was to identify objective parameters for measuring embryo quality instead of those based on morphological appearance. We have investigated the relationship between embryo quality as assessed by morphological appearance and the n

A Feulgen staining procedure that stains the DNA of individual fixed nuclei stoichiometrically was used to analyse cytophotometrically the incidence of total ploidy and mixoploidy in 28 day-7 bovine embryos that had been fixed after collection ('non-

Whether the luteinizing hormone (LH) peak induces oocyte maturation in other than preovulatory follicles was examined by analysing protein synthesis and phosphorylation patterns of bovine oocytes from non-atretic and atretic follicles of various size

To investigate protein synthesis and phosphorylation during bovine oocyte maturation in vivo, oocytes were collected at consecutive times after the preovulatory luteinizing hormone (LH) peak. Therefore, heifers treated for superovulation were ovariec

Bovine cumulus oocyte complexes were cultured for various periods and either denuded and orcein stained or radiolabeled with 35S-methionine or 32P-orthophosphate. Specific inhibitors were added to the culture medium to investigate mRNA and protein sy

Bovine cumulus oocyte complexes (COCs) were isolated from antral ovarian follicles (4-8 mm). Immature COCs were classified into four categories, based on the homogeneity and clearness of the ooplasm and the transparency and compactness of the cumulus
