Multiple roles of hypoxia in ovarian function: roles of hypoxia-inducible factor-related and -unrelated signals during the luteal phase [PDF]
There is increasing interest in the role of oxygen conditions in the microenvironment of organs because of the discovery of a hypoxia-specific transcription factor, namely hypoxia-inducible factor (HIF) 1.

Effects of Splenectomy on Luteolysis in Pseudopregnant Rabbits.
The effects of splenectomy on luteolysis in pseudopregnant rabbits were observed. Pseudopregnancy was induced in the rabbits by mating with vasoligated mature males and injection of human chorionic gonadotrophin (D0). In these rabbits, the concentration of serum progesterone increased for 7 days after the induction of pseudopregnancy.

Investigations of Sodium Dependent Vitamin C Transporters in the Ovine Corpus Luteum [PDF]
SVCT1 and SVCT2 are two forms of sodium dependent vitamin C transporters within the sheep corpus luteum. A truncated version of SVCT2 has been observed in the human, and is inhibitory to SVCT1 & 2.
