These were COCs with compact cumulus cell layers and oocytes
with homogenous (grade A) or slightly heterogeneous (grade B) cytoplasm.
Total number of oocytes
differed significantly between sites, possibly attributable to differing body sizes.
Samples (1 g) were cut from the center of each ovary, and oocytes
present were counted.
They also cover pathology, including omics for oocyte
selection, alterations in gene expression, transgenerational risks by exposure in utero, obesity and oocyte
quality, the safety of ovarian stimulation, epigenetics, and the genetic basis for primary ovarian insufficiency, and technology and clinical medicine, with discussion of polar body screening for aneuploidy and transplantation of ovarian tissue or immature oocytes
to preserve and restore fertility.
An important aspect of our scheme is presence-absence of a clutch of mature oocytes
or ripe eggs in the ovary.
In mice fed a high-fat diet (HFD) for 16 weeks, ovulation rate, embryo development, placental function, ovarian function, and mitochondrial function were affected in oocytes
(Cardozo et al.
For females, the size of the oocytes
(mean diameter obtained from measuring 100 oocytes
per specimen) was determined from histological slides, except for when the cockles were in an inactive stage.
Fecundity values ranged from 87,569 to 398,986 oocytes
, and mean potential fecundity was estimated at 78,929 (standard error of the mean [SE] 13,648) oocytes
per kilogram of mature female.
A brilliant cresyl blue (BCB) staining test can show different intracellular activity of G6PDH in oocytes
because the G6PDH enzyme converts BCB from blue to a colorless state.
In their first conventional ICSI attempt, 26 oocytes
were collected, 3 embryos were transferred and following OHSS, she had negative P hCG value.
This equipment is expected to collect two electrode voltage clamp electrophysiology data from multiple oocytes
(96 or more) in an automated fashion.
These findings support that ovarian stimulation is safe for maximizing five birth rates when you use acceptable limits of ovarian stimulation such as less than 20 oocytes
