Mechanisms of angioregression of the corpus luteum [PDF]

open access: yesFrontiers in Physiology, 2023
The corpus luteum is a transient ovarian endocrine gland that produces the progesterone necessary for the establishment and maintenance of pregnancy. The formation and function of this gland involves angiogenesis, establishing the tissue with a robust ...

The inadequate corpus luteum [PDF]

open access: yesReproduction and Fertility, 2021
The corpus luteum is the source of progesterone in the luteal phase of the cycle and the initial two-thirds of the first trimester of pregnancy. Normal luteal function is required for fertility and the maintenance of pregnancy.

New Aspects of Corpus Luteum Regulation in Physiological and Pathological Conditions: Involvement of Adipokines and Neuropeptides

open access: yesCells, 2022
The corpus luteum is a small gland of great importance because its proper functioning determines not only the appropriate course of the estrous/menstrual cycle and embryo implantation, but also the subsequent maintenance of pregnancy.

B-Mode and Doppler Ultrasonographic Changes in the Corpus Luteum, Uterus, and Uterine Artery During Early Pregnancy in Cows [PDF]

open access: yesLife
The aim of this study was to comparatively evaluate echotextural and hemodynamic changes in the corpus luteum (CL), uterus, and uterine artery, together with serum progesterone (P4) concentrations, using B-mode and Doppler ultrasonography between days 5 ...

Conception rate according to the size and location of corpus luteum and coexistent follicle before embryo transfer in Hanwoo [PDF]

open access: yesJournal of Animal Science and Technology
The size and location of the corpus luteum and the presence of coexistent follicles are crucial factors in synchronizing recipients and determining the suitability for embryo transfer.

Angiogenesis in the corpus luteum [PDF]

open access: yesReproductive Biology and Endocrinology, 2003
The corpus luteum (CL) is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual ...

Angiogenesis and Apoptosis: Data Comparison of Similar Microenvironments in the Corpus Luteum and Tumors [PDF]

open access: yesAnimals
The corpus luteum is a temporary endocrine gland formed in the ovary after ovulation, and it plays a critical role in animal reproductive processes. Tumors rely on the development of an adequate blood supply to ensure the delivery of nutrients and oxygen

Integrated hormonal, metabolic, and epigenetic regulation of corpus luteum function: insights into steroidogenesis, angiogenesis, and regression [PDF]

open access: yesFrontiers in Endocrinology
The corpus luteum is a transient endocrine structure essential for establishing and maintaining early pregnancy, primarily through the secretion of progesterone.

The Role of the Guanosine Nucleotide-Binding Protein in the Corpus Luteum

open access: yesAnimals, 2021
The corpus luteum is a temporary endocrine gland in the ovary. In the ovarian cycle, repeated patterns of specific cellular proliferation, differentiation, and transformation occur that accompany the formation and regression of the corpus luteum ...

Synchronization with estradiol benzoate in the presence of the corpus luteum in Wagyu cows increases the number of medium follicles but does not interfere with in vitro production of embryos

open access: yesSemina: Ciências Agrárias, 2021
Reproductive biotechnologies emerge as an important element for livestock, however, some strategies must be modified to adapt the different breeding systems, such as the use of follicular synchronization protocols.
