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 ...
Oocyte viability and cortical activation under different salt solutions in Prochilodus lineatus (Teleostei: Prochilodontidae)
(2017-12-01)
This study aimed to evaluate the effect of five salt solutions in the maintenance of morphological features of cortical alveolus, hydration and fertilization capacity of Prochilodus lineatus oocytes. For this purpose, five ...
GnRH agonist versus GnRH antagonist in assisted reproduction cycles: oocyte morphology
(Biomed Central Ltd., 2012-04-27)
Background: The selection of developmentally competent human gametes may increase the efficiency of assisted reproduction. Spermatozoa and oocytes are usually assessed according to morphological criteria. Oocyte morphology ...

Histochemical and morphological features of biopsied and stripped oocytes from the Brazilian endangered teleost pirapitinga, Brycon nattereri (Characiformes)
(Cambridge Univ Press, 2015-06-01)
The aim of the present study was to characterize biopsied and stripped oocytes from the Brazilian endangered teleost pirapitinga (Brycon nattereri) using histochemical and morphological analyses. Biopsied oocytes had a ...

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 ...
