Concentration of Prostaglandin F2alpha (PTGF), Prostaglandin E2 (PTGE), Estradiol (E2), and Progesterone (P4) in follicular fluid (FF) of preovulatory follicles collected at (I) 0 h, (II) 4 h, (III) 10 h, (IV) 20 h, and (V) 25 h relative to injection of GnRH to induce an LH surge.

Results are presented as the mean ± SEM (ng/ml FF, n = 8–12 follicle/group from 5 animals). Different superscripts denote significantly different values (P <0.05).
