“A significant inverse relationship existed between the accumulation rates of progesterone and LTB4 in the luteal cells.”
“Furthermore, the addition of LTB4 inhibited progesterone production in a dose-dependent manner in both the presence and absence of hCG.”
“In conclusion, LTB4 could be synthesized by human corpora lutea in vitro, and correlated inversely with the secretion rates of progesterone.”
