In vivo oocyte recovery and in vitro embryo production from bovine oocyte donors treated with progestagen, oestradiol and FSH.
The effect of treatment of donor cattle with progestagen and oestradiol or FSH on in vivo oocyte recovery and in vitro embryo production was studied. Forty-eight beefxFriesian cows formed eight replicates of six treatments in a 2 (no steroid versus steroid)x3 (none, single or multiple dose(s) of FSH) factorial design in which follicles were aspirated once weekly for 3 weeks. Oocytes were graded...
متن کاملMolecular markers for oocyte competence in bovine cumulus cells.
This study aimed to quantify the expression of candidate genes in cumulus cells (CCs) from cumulus-oocyte complexes (COCs) with high and low potential for in vitro development up to the blastocyst stage. First, the effects of individual culture and biopsy on embryo development were evaluated. Individuals cultured using the well of the well system were compared with individuals cultured in 20 μL...
متن کاملOocyte developmental competence and embryo quality: distinction and new perspectives
In vitro embryo production is the cornerstone of infertility treatment in human and is increasingly used in cattle to propagate high genetic merit animals. To increase its efficiency, many different approaches have been tested all of which stem from the concepts of oocyte quality and developmental competence. Presented here are recently reported findings and perspectives related to bovine oocyt...
متن کاملI-11: The Use of Oxygen Consumption for Oocyte and Embryo Selection
Assisted human reproduction is characterized by a high variability in results regarding pregnancy and birth rates. In fact, in a cohort of fertilized oocytes from the same stimulation cycle, the development rate varies drastically, even though produced at the same time and under similar conditions. This variability results in large differences in implantation potential of human embryos develope...
