Suppression of lipid peroxidation in human spermatozoa by prostatic inhibin.
Loss of sperm motility owing to the production of hydrogen peroxide by lipid peroxidation is regulated by yet unidentified prostatic factor(s). Inhibinlike peptide (HSPI) of prostatic origin isolated from human seminal plasma and having a molecular weight of about 10,400 daltons was studied for its effect on ascorbate-induced lipid peroxidation in human spermatozoa. Dose-related suppression of lipid peroxidation occurred at a dose level of 0.25, 0.5, and 1.0 micrograms. HSPI may be one of the factors involved in the regulation of lipid peroxidation and therefore sperm motility.
