Perturbations in Lineage Specification of Granulosa and Theca Cells May Alter Corpus Luteum Formation and Function [PDF]

Frontiers in Endocrinology, 2019
Anovulation is a major cause of infertility, and it is the major leading reproductive disorder in mammalian females. Without ovulation, an oocyte is not released from the ovarian follicle to be fertilized and a corpus luteum is not formed.

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

Semina: 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.

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

Cells, 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.

Expression of leptin and leptin receptor transcript in ovine corpus luteum [PDF]

Iranian Journal of Veterinary Medicine, 2018
Background: Leptin, the product of the obesity (ob) gene, acts as a signaling adipokine for modulating food intake, energy metabolism and reproductive functions in mammals. Leptin’s effects on the reproductive system at various levels of the hypothalamic-

Gene Expression Profiling of Corpus luteum Reveals Important Insights about Early Pregnancy in Domestic Sheep [PDF]

, 2020
The majority of pregnancy loss in ruminants occurs during the preimplantation stage, which is thus the most critical period determining reproductive success. Here, we performed a comparative transcriptome study by sequencing total mRNA from corpus luteum
