Seminal prostaglandins in men with subnormal sperm motility and therapeutic treatment.
The contents of prostaglandins in seminal plasma from a total of 73 men were evaluated. The subjects were grouped as follows: normospermic men, patients with impaired motility, patients with small untreated varicocele and patients with impaired motility and Kallikrein therapy. Sperm density, morphology and motility were examined. High performance reversed phase liquid chromatography (HPLC) in combination with specific radioimmunoassays were used for the determination of PGE2, PGI2 and PGF2 alpha. There was a significant difference (p less than 0.025; F-test) between the PGI2 concentrations in patients with impaired motility (5.6 +/- 1.4 pg/mg protein) and normal men (8.8 +/- 3.7 pg/mg protein). PGE2 and PGF2 alpha were significantly different in patients with varicocele (p less than 0.025, F-test). Wide ranges of prostaglandins occurred in the Kallikrein-group with no significant differences. We conclude that: a) PGI2 is an additional prostaglandin compound in seminal plasma, b) its measurement may not be useful as diagnostic parameter in subfertile men and c) Kallikrein has no influence on the prostaglandin content in seminal plasma and other seminal parameters as motility, motility index and sperm counts.
