A Color Atlas for Human Assisted Reproduction: Laboratory ...
a degenerative effect on the polar body (39) that can be related to the aging of
the oocyte, leading to spindle damage and loss of chromosomes by scattering (
40,41). Recent studies have correlated the morphology of the first polar body with
...

Human Physiology: From Cells to Systems
The nutrient-poor polar body soon degenerates. FORMATION OF A MATURE
OVUM Actually, the secondary oo- cyte, and not the mature ovum, is ovulated
and fertilized, but common usage refers to the developing female gamete as an
ovum ...
Chromatin differences between the first and second polar bodies may depend
upon the sequential appearance of substances regulating chromatin
morphogenesis during the course of polar body formation. For example, if the
egg/zygote ...

Reproductive Endocrinology and Infertility: Integrating ...
In ICSI cases, which only account for about 40% of all ART cases performed, the
only morphological features that are generally considered are: is the oocyte
mature/MII (have a visible polar body)? Are sperm motile and the correct shape?
Douglas T. Carrell, C. Matthew Peterson, 2010

Genetic Disorders and the Fetus: Diagnosis, Prevention and ...
the first and second polar body chromosomes may be visualized and considered
for a possible preimplantation prediction of the karyotype of the oocyte.
Cytogenetic investigation of the first polar body may have important practical
implications ...

The genetics problem solver
(b) in the first polar body? (c) in the second polar body? (d) in the secondary
oocyte? Assume that the animal is diploid. SOLUTION; In solving this problem,
one must keep in mind how meiosis is coordinated with spermatogenesis and ...

Gynaecology For Postgraduate And Practitioners
During maturation of the oocyte, the metaphase spindle is formed, meiosis
proceeds and the polar body is extruded. Formation of the first polar body results
from a highly asynchronous cell division at the end of the first meiotic division.

Since the haploid number is 10, the number of chromosomes in the diploid
spermatogonium is 2x 10 or 20 chromosomes . b) It is essential to remember that
while the polar body is formed as a result of unequal distribution of cytoplasm in ...

(a) An unfertilized human oocyte and its first polar body enclosed in the zona
pellucida. (b) A fertilized human egg with two pronuclei, the larger probably being
the male pronucleus. A polar body at the upper surface of the oocyte appears to ...
