Concentrations of prostaglandin E1 (PGE1), and prostaglandin E2 (PGE2) (combined in the same radioimmunoassay) and prostaglandin F2 alpha (PGF2 alpha) were analyzed in circulating plasma and seminal vesicles of 3- and 26 to 27-month-old males and in circulating plasma and ovaries of 3-, 6-, 14 to 18- and 26 to 30-month-old female C57BL/6NNia mice. The amount of PGE declined in the plasma (P less than 0.05) and seminal vesicles (P less than 0.02) of aged male mice, whereas PGF2 alpha concentrations remained unchanged. There were no statistical differences in plasma or ovarian concentrations of PGE or PGF2 alpha when comparing the various age groups of female mice. It does not appear as if age-related changes in prostaglandins play a significant role in reproductive senescence.
