[Cholesterol and phospholipids in human seminal plasma before and after vasectomy]

Before and 2.6 months after vasectomy the alterations of secretory capacity and physiologic damage of the accessory genital glands, were evaluated by means of chemical analyses of certain constituents of seminal plasma such as free cholesterol, esterified cholesterol and phospholipids. The results of these studies showed that the ratio between the concentration of free cholesterol and esterified cholesterol is constant six months after vasectomy and the concentration of phospholipids decreases two months after vasectomy. These results are significant and may be important to know the alterations of secretory capacity of the human genital glands after vasectomy.
