Thus, the viability of oocytes
after being exposed to cryoprotectants at different concentrations was investigated by more than one method (TB, GVBD, Fertilization and Hatching rates), because there is a methodology that is best applied for each stage of oocyte
development and making assumptions based on one single test is too risky (PLACHINTA et al., 2004).
One may speculate that it is difficult to achieve a perfect synchronization between oocyte
maturity and endometrium receptivity with the described technique.
This process, called apoptosis, is triggered in oocytes
by the protein p63.
Vitrification method is associated with ultrastructural alterations in specific areas of oocyte
which is probably related to the decrease of vitrified oocytes
competence for Maturity (Wu et al., 2006).
Ovarian reserve is a measurement of the ovarian follicular pool1 and determines the capacity of the ovary to produce oocytes
that are capable of fertilization.
Lipopolysaccharide initiates inflammation in bovine granulosa cells via the TLR4 pathway and perturbs oocyte
meiotic progression in vitro.
Based on the histological and histochemical characteristics (size, cell morphology and distribution pattern, and H-E staining of yolk), five phases of the oogenesis cycle were identified, and furthermore, according to their cellular characteristics, 11 oocyte
substages were distinguished in Lithodes santolla.
A 5000 IU intramuscular injection of human chorionic gonadotropin (hCG) (inj.hCG, Livzon, China) was given for oocyte
The biochemical and molecular state of oocyte
helps in the maturation of oocyte
for fertilization and maturation to an embryo.
In the second form of atresia, only the oocyte
is released into the ovarian lumen, leaving behind the granulosa and empty follicular envelops.
The mean retrieved oocyte
count was 11.15, and the mean retrieval time was 14.4 minutes.
Accumulation of oocytes
: a new strategy for managing low-responder patients.
