Role of the Ovum in Follicular Luteinization

Endocrinology, 1970
To study the effect of the oocyte on the functional activity of granulosa cells, clear mature follicles of estrous rabbits were either punctured or ovectomized. Three days after treatment, granulosa cells of punctured follicles failed to show histological signs of luteinization. Six days after puncturing both oocytes and granulosa cells were degenerate

Maturation of Ovum

1989
After the oocyte has attained its full growth during the vitellogenic phase of oogenesis in reptiles and birds, it becomes ready for the next phase of oogenesis, i.e., the resumption of reduction division for the final maturation. The oocyte final maturation, which forms a pre-requisite for successful fertilization, consists of the germinal vesicle ...

PARTHENOGENETIC CLEAVAGE OF THE ARMADILLO OVUM

, 1913
The evidence derived from a study of large numbers of armadillo ovaries demonstrates, I believe, that parthenogenetic cleavage takes place in atretic follicles of this species of mammal.

Effect of donor age on the developmental competence of bovine oocytes retrieved by ovum pick up.

Reproduction in domestic animals = Zuchthygiene, 2012
To study the effect of donor age on oocyte developmental competence and steroid profiles, the crossbred cow (Murray Grey × Brahman) in Yunnan province of China were selected and divided into three groups according to its age.

THE DIAGNOSIS OF BLIGHTED OVUM BY SONAR

BJOG: An International Journal of Obstetrics & Gynaecology, 1972
SummaryThe outcome of 141 cases of bleeding in the first trimester of pregnancy has been correlated wit the findings obtained at the first and subsequent ultrasonic examinations. In 66 patients who aborted the ultrasonic appearances suggested a diagnosis of blighted ovum in 57.

Die lebende menschliche Eizelle

Verhandlungen der Deutschen Gesellschaft f�r Gyn�kologie, 1958
Abstract Living human follicular and tubal ova have been studied by means of phase contrast microscopy, with special reference to the cytology and physiology of the corona radiata cells, polar body formation, cytoplasmic and nuclear constituents, spermatozoan behavior about and penetration of the ovum, and early cleavage.
