Individual luteolysis pattern after GnRH-agonist trigger for final oocyte maturation. [PDF]
PLoS ONE, 2017 Final oocyte maturation using GnRH-agonist trigger in a GnRH-antagonist protocol is increasingly common, as ovarian hyperstimulation syndrome is almost completely avoided.

Journal of Dairy Science, 2022 : Our objective was to determine the effect of inducing an accessory corpus luteum (CL) with human chorionic gonadotropin (hCG; 3,300 IU) on d 7 (hCG7) or 2 accessory CL with hCG on d 7 and 13 (hCG7+13) of the estrous cycle in noninseminated lactating ...

Intraovarian regulation of luteolysis. [PDF]
Bioscientifica Proceedings, 2019 The corpus luteum is a transient gland, which is only functional for 17-18 days in the cyclic cow or for up to 200 days in the pregnant cow. Regression of the corpus luteum is essential for normal cyclicity as it allows the development of a new ovulatory

The oxytocin receptor, luteolysis and the maintenance of pregnancy. [PDF]
Bioscientifica Proceedings, 2019 During luteal regression episodic pulses of oxytocin secretion become coupled to the release of prostaglandin F2 alpha (PGF2 alpha) following synthesis of endometrial oxytocin receptors, but in early pregnancy the inhibition of oxytocin receptor ...

Necroptosis in primate luteolysis: a role for ceramide [PDF]
Cell Death Discovery, 2019 The corpus luteum (CL) is a transient endocrine organ, yet molecular mechanisms resulting in its demise are not well known. The presence of phosphorylated mixed lineage kinase domain-like pseudokinase pMLKL(T357/S358) in human and nonhuman primate CL ...

Journal of Dairy Science, 2022 : Objectives were to evaluate the effect of 2 analogs of PGF2α (cloprostenol vs. dinoprost) and 2 doses (1 injection vs. 2 injections) on luteolysis, follicle diameter, hormonal concentrations, and time to ovulation in dairy heifers.

Controlled internal drug release (CIDR) removal before luteolysis prolongs estrus interval and increases silent heat risk in Japanese Black cows [PDF]
The Journal of Reproduction and DevelopmentThis study aimed to improve estrus management in Japanese Black cows by investigating the effects of controlled internal drug release (CIDR) treatment on luteal function including luteolysis and estrous characteristics.

NOX2/NOX4-associated oxidative stress contributes to G6PD-associated metabolic remodeling and ferroptosis during mice luteolysis [PDF]
Redox ReportObjective Ferroptosis has been shown to participate in luteolysis, yet the upstream signals and metabolic remodeling that trigger it remain unknown. This study aims to clarify these mechanisms.Methods Physiological postpartum and PGF2α-induced luteolysis

Integrated hormonal, metabolic, and epigenetic regulation of corpus luteum function: insights into steroidogenesis, angiogenesis, and regression [PDF]
Frontiers in EndocrinologyThe corpus luteum is a transient endocrine structure essential for establishing and maintaining early pregnancy, primarily through the secretion of progesterone.

The Journal of Reproduction and Development, 2022 In mammals, the corpus luteum (CL) is a transient organ that secretes progesterone (P4). In the absence of pregnancy, the CL undergoes regression (luteolysis), which is a crucial preparation step for the next estrous cycle.
