Prostaglandin concentrations in the semen of fertile men

Abstract

Summary. The PG concentrations in the semen of 23 fertile men were 73 μg PGE/ml, 267 μg 19-OH PGE/ml, 2·1 μg PGF/ml and 18·3 μg 19-OH PGF/ml. The wide ranges of concentrations found for the PGEs (2–272 μg/ml) and for the 19-OH PGEs (53–1094 μg/ml) throw some doubt on the previously established correlation between infertility and low prostaglandin concentrations.
