New approaches regarding the in vitro maturation of oocytes: Manipulating cyclic nucleotides and their partners in crime
(2017-01-01)
Several discoveries have been described recently (5-10 years) about the biology of ovarian follicles (oocyte, cumulus cells and granulosa cells), including new aspects of cellular communication, the control of oocyte ...
Exploring the pros and cons of new approaches for gamete cross-border donation based on fresh and vitrified oocytes
(Universa Press, 2020-06-01)
As highlighted by European statistics, the employment of donor oocytes is a growing option for women who cannot make use of their own gametes. As the potential recipients are continuously increasing in number, a donor ...
Control of oocyte maturation
(2014-01-01)
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, ...

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, ...
Correlação entre os dismorfismos oocitários e os resultados da fertilização in vitro
(2012-03-01)
In assisted reproduction, the selection of gametes to achieve better clinical outcomes is a crucial task of embryologists. The quality of the oocyte is a key factor in female fertility, reflecting the intrinsic potential ...
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 ...

The use of transmission electron microscopy and oocyte transfer to evaluate in vitro maturation of equine oocytes in different culture conditions
(Elsevier B.V., 2006-04-01)
The current study evaluates the ability of equine oocytes matured in different conditions to undergo nuclear and cytoplasmic maturation.. After oocyte transfer, embryonic development was diagnosed at 1.5 and 90 days of ...

Vitrification of immature feline oocytes with a commercial kit for bovine embryo vitrification
(2013-04-01)
The aim of this study was to evaluate the suitability of a commercial kit for bovine embryo vitrification for cryopreserving cat oocytes and to evaluate comparatively the effects of its use with slow freezing procedure on ...
