Maintenance or regression of the corpus luteum during multiple decisive periods of bovine pregnancy
(Animal ReproductionBrasil, 2016)In ruminants, there are specific times during the estrous cycle or pregnancy when the corpus luteum (CL) may undergo regression. This review has attempted to summarize the physiological and cellular mechanisms involved in ... -
Mechanisms for rescue of corpus luteum during pregnancy: gene expression in bovine corpus luteum following intrauterine pulses of prostaglandins E1 and F2α
(Biology of ReproductionEstados Unidos, 2017-12-27)In ruminants, uterine pulses of prostaglandin (PG) F2α characterize luteolysis, while increased PGE2/PGE1 distinguish early pregnancy. This study evaluated intrauterine (IU) infusions of PGF2α and PGE1 pulses on corpus ... -
Physiological mechanisms involved in maintaining the corpus luteum during the first two months of pregnancy
(Animal ReproductionBrasil, 2018-09)Maintenance of the corpus luteum (CL) during pregnancy is essential for continuing the elevated circulating progesterone (P4) that is required to maintain pregnancy. The mechanisms that protect the CL during early pregnancy ... -
Pivotal periods for pregnancy loss during the first trimester of gestation in lactating dairy cows
(TheriogenologyEstados Unidos, 2016-04-22)Loss of pregnancy can occur at many different stages of gestation and for a variety of causes but clearly produces a negative impact for reproductive and economic performances of dairy herds. This review describes four ... -
Proposal of a new model for CL regression or maintenance during pregnancy on the basis of timing of regression of contralateral, accessory CL in pregnant cows
(TheriogenologyEstados Unidos, 2017-02)In bovine pregnancy, regression or maintenance of the corpus luteum (CL) is mediated through local communication pathways between embryo, uterus, and ovary with Days 16 to 25 of pregnancy generally recognized as the pivotal ... -
