title: Effects of intravenous administration of brain phospholipids on gonadotropin release in man.
abstract: Administration of 600 mg of brain phospholipids i.v. in normal adult volunteers results in a significant decrease of the testosterone circulating levels. This phenomenon is not accompanied by a modification in gonadotropin quantitative levels, but by a reduction in LH pulsatility. This seems to be important for the peripheral biological activity of LH.
