Control of Luteolytic Sensitivity in the Porcine Corpus Luteum

open access: yes, 2008
The porcine corpus luteum (CL) is unusual in that it does not show a luteolytic response to an exogenous dose of Prostaglandin F-2 (PGF-2 until after day 12 of an 18-21 day cycle, which is in marked contrast to other farm animal ...

A biochemical investigation of the corpus luteum [PDF]

open access: yes, 1931
A method for the preparation of potent extracts of the corpus luteum, which produce progestational proliferation and inhibition of the reaction of the uterus to pituitrin on subcutaneous injection in the rabbit,is described.

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, Volume 58, Issue 4, Page 970-980, July 2026.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Corpus Luteum Morphology and Vascularization Assessed by Transvaginal Two-dimensional and Three-dimensional Ultrasound

open access: yes, 2007
Background Our aim was to describe the corpus luteum morphology by two-dimensional ultrasound correlated by its vascularization and volume by 3D ultrasound and study the possible relationship between serum progesterone levels and the corpus luteum ...

Exploring Progesterone Levels and Scaled Mass Index as Predictors of Pregnancy in Free‐Ranging Belugas

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Monitoring pregnancy rates can provide vital information regarding a population's viability and trajectory. This study combined drone‐based photogrammetry with biopsy darting to determine if the Scaled Mass Index (SMI) estimated from aerial images can be used to identify pregnant, free‐ranging St.

Mutant mouse models and their contribution to our knowledge of corpus luteum development, function and regression

open access: yesReproductive Biology and Endocrinology, 2003
The corpus luteum is a unique organ, which is transitory in nature. The development, maintenance and regression of the corpus luteum are regulated by endocrine, paracrine and autocrine signaling events.

Follicular Development Dynamics and Plasma Progesterone Profile during the Estrous Cycle of Dairy Cows

open access: yesAnimal Production: Indonesian Journal of Animal Production, 2008
A total of five local Friesian cows, 4 to 5 years, healthy, reproductively sound, were used in the study to understand the development dynamics of dominant follicles and plasma progesterone profile during estrous cycle.

Extracellular matrix of the corpus luteum

open access: yes, 2006
The potential importance of the extracellular matrix to luteal formation and development, additional development in response to pregnancy hormones in some species, and luteal function and regression is possibly under-appreciated.
