Effect of prostaglandin F2α on ovarian, adrenal, and pituitary hormones and on luteal blood flow in mares
The effect of a single injection of prostaglandin F2α (PGF) during mid-diestrus on systemic
concentrations of progesterone, LH, FSH, estradiol, and cortisol and on blood flow to the
corpus luteum was studied in 10 controls and 10 PGF-treated mares. Blood flow was
assessed by estimating the percentage of corpus luteum with color-Doppler signals of blood
flow during real-time scanning of the entire structure and by the diameter of the vascular
pedicle near its attachment to the ovary. Treatment was done 8 days after ovulation and 0h …
