Secretion of progesterone from the corpus luteum is required for normal pregnancy in all
domestic animals. However, if pregnancy does not occur following estrus and mating …

After the luteinizing hormone (LH) surge, the cells that remain from the ovulated follicle
undergo a process of differentiation termed luteinization. Two key features of the cells after …

The lifespan of the corpus luteum is influenced and can be manipulated by mechanisms
(and their interactions) associated with secretions from the pituitary, ovary, uterus and …

The ready accessibility of the bovine corpus luteum by enucleation through a slit in the
anterior vagina (Casida, 1960) enabled researchers to conduct studies in vitro with …

Current and emerging concepts of follicle growth and ovulation, hypothalamic-pituitary-
ovarian interactions, corpus luteum function and estrous cycle regulation in cattle, sheep …

The main function of the corpus luteum (CL) is production of progesterone (P4). Adequate
luteal function to secrete P4 is crucial for determining the physiological duration of the …

In the domestic species, regression of the corpus luteum is dependent on uterine release of
prostaglandin (PG) F2α. Despite the central role of PGF2α in luteolysis, very little is known …

Current and emerging concepts on regulation of bovine corpus luteum function by various
metabolites of arachidonic acid are reviewed. A series of experiments are presented which …

The corpus luteum is composed of two distinct steroidogenic cell types, both of which
contribute significantly to the total progesterone secreted during the luteal phase of the …

The purpose of this overview is to highlight important steps of ovarian regulation during
follicle development, ovulation and the life span of corpus luteum (CL) in ruminants. The …
