title: Concentration of interleukin-1 beta correlates with prostaglandin E2 and F2 alpha in human pre-ovulatory follicular fluid.
abstract: To investigate the role(s) of interleukin-1 beta (IL-1 beta) in human ovarian function, we measured the concentrations of IL-1 beta, prostaglandins (PGs) and steroids in follicular fluid of 90 stimulated ovaries, with reference to oocyte maturation. Concentrations of IL-1 beta were significantly higher in the follicles from which mature oocytes were recovered than in follicles from which oocytes could not be recovered (P < 0.05). IL-1 beta concentrations also increased in association with oocyte maturation. Positive significant correlations were seen between IL-1 beta and prostaglandin E2 (PGE2) (r = 0.47, P < 0.001), and between IL-1 beta and prostaglandin F2 alpha (PGF2 alpha) (r = 0.22, P < 0.05) in pre-ovulatory follicular fluid, but not between IL-1 beta and oestradiol, or between IL-1 beta and progesterone. Follicular fluid IL-1 beta might contribute to prostaglandin-induced oocyte maturation and ovulation.
