“H-7 (10(-3)M, 10(-4)M and 10(-5)M) and NDGA (10(-3)M, 10(-4)M and 10(-5)M) significantly inhibited (P < 0.05) the effect of GnRH agonist on progesterone and estradiol production by the granulosa cells.”
“Furthermore, the gonadotrophin release by 1 nM GnRH was inhibited by nordihydroguaiaretic acid (a lipoxygenase inhibitor) with an IC50 of about 5 microM. Thus, the hydroperoxy (but not hydroxy) products of 12-lipoxygenase may be involved in the release of pituitary hormones especially LH and FSH.”
“In contrast, pretreatment with the lipoxygenase inhibitor nordihydroguaiaretic acid decreased the total LH response to GnRH by 60%, reduced the magnitude and latency of the first LH peak, and shortened the duration of the response.”
