Luteolysis: a neuroendocrine-mediated event.

Physiological Reviews, 1999
In many nonprimate mammalian species, cyclical regression of the corpus luteum (luteolysis) is caused by the episodic pulsatile secretion of uterine PGF2α, which acts either locally on the corpus luteum by a countercurrent mechanism or, in some species, via the systemic circulation.

Role of PGF2α in luteolysis based on inhibition of PGF2α synthesis in the mare

Theriogenology, 2013
The effects of inhibition of PGF2α synthesis on luteolysis in mares and on the incidence of prolonged luteal activity were studied in controls and in a group treated with flunixin meglumine (FM), a PGF2α inhibitor (n = 6/group).

Luteolysis in Bos indicus cows on Days 5 and 7 of estrous cycle with varying doses of PGF2α

Theriogenology, 2016
The aim of this study was to evaluate luteolysis using three doses of PGF2α on Day 5 or Day 7 of the estrous cycle in nonlactating Nellore (Bos indicus) cows. Cows (n = 323) were assigned within date of estrus (Day 0 of estrous cycle) to receive 12.5, 25.

Luteolysis in early diestrous beagle bitches

Theriogenology, 1988
To induce luteolysis early in diestrus, 15 mated beagles were treated with 250 microg/kg prostaglandin F2alpha (PG), administered subcutaneously twice daily for 4 d, from Day 5 to Day 8 after the onset of cytological diestrus. They were divided into three groups of five bitches each: Group 1 received PG only.

The transition between preluteolysis and luteolysis in cattle

Theriogenology, 2011
Novel characterization of the transition between preluteolysis and luteolysis was done in seven heifers. Blood samples were collected hourly and assayed for progesterone (P4), 13-14-dihydro-15-keto-PGF2α (PGFM), and estradiol (E2). The peaks of P4 oscillations were used to designate the transitional hour in each heifer.
