However, follicular atresia has been associated with the presence of corpora lutea
in the ovaries, because they produce steroid hormones, elevating the concentration of progesterone in plasma during the period of gestation (Xavier, 1987; Mendez-de la Cruz et al.
No corpora lutea
were found in the ovaries of 27 juvenile females, but two killed between 2-13 March (i.
The large deposits of amyloid in the corpora lutea
of the ovary recall that in human pathology the amyloid often shows an affinity for areas of increased or abnormal cellular activity.
Body and ovarian weights, the number and diameter of follicles and corpora lutea
in the control and caffeine-treated groups were compared by one-way analysis of variance (ANOVA) and Tukey's post hoc test.
In addition, ovaries from BPA500 animals had fewer corpora lutea
, fewer antral follicles, and more atretic follicles than did those from controls.
There was a significant decrease in the body weight and the number and the mean values of corpora lutea
in groups 2, 3 and 4.
Slides of ovaries were examined to identify deposition of yolk, corpora lutea
, or both.
No histological evidence was found that multiple clutches were produced as indicated by, for example, corpora lutea
from a previous clutch and concomitant yolk deposition for a subsequent clutch.
0 ng/ml around estrus suggest that in goats the corpora lutea
constitute the major source of progesterone.
In a 29-day mouse study, lack of corpora lutea
and smaller ovaries were observed in females and histopathologic changes in the testis and epididymis and enlarged adrenals were observed in males at [greater than or equal to] 14 mg/kg bw.
10:50 "Proliferation of vascular endothelial cells and pericytes in ovine corpora lutea
(CL) throughout the estrous cycle.
One female from February (LACM 166231) contained corpora lutea
and convoluted oviducts indicating parturition had recently occurred.
