title: Radioimmunoassay of prostaglandins in the semen of fertile men.
abstract: Specific antisera and iodinated tracers, as well as strict conditions of sample storage PG extraction and purification, were used to estimate prostaglandins (microgram/ml) in the semen of fertile men: 19-OH-PGE (1 + 2) (350), 19-OH-PGF-alpha (22), PGE-2 (15), PGE-1 (6.2), PGF-2 alpha (2.3), PGF-1 alpha (1.3), 6-keto-PGF-1 alpha (less than 1), PGD-2, 13,14-dihydro-15-keto-PGF alpha and TXB-2 (less than 0.1). Only PGE-2 (50 pg/ml) was detectable in rat seminal fluid.
