Embryological Aspects of Oocyte In Vitro Maturation
In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author’s experience. In IVM cycles,...
متن کاملFailure of oocyte maturation: possible mechanisms for oocyte maturation arrest.
For human IVF, the patient's ovaries are hormonally stimulated to ensure the collection of fully matured oocytes that are at the metaphase II stage. Only these oocytes can be successfully fertilized either when mixed with sperm or after ICSI. Nevertheless, in some cases immature or maturing oocytes are recovered from follicles. Surprisingly, sometimes these oocytes do not complete maturation wh...
متن کاملOocyte maturation and ovum quality in pigs.
Oocyte quality in pigs is defined as the potential of that oocyte to develop into a viable offspring. There is increasing evidence that the programming of the oocyte must be completed before leaving the ovarian follicle, including both nuclear and cytoplasmic maturation. Pig oocytes matured in vitro under basic conditions are deficient in some, as yet unidentified, cytoplasmic factors and thus ...

متن کاملControl of oocyte maturation
Oocyte maturation is a complex process involving nuclear and cytoplasmic maturation. The nuclear maturation is a chromosomal segregation and the cytoplasmic maturation involves the reorganization of the cytoplasmic organelles, mRNA transcription and storage of proteins to be used during fertilization and early embryo development. The mechanism of oocyte maturation in vivo and in vitro still are...
