Effect of chronic alcoholism on semen--studies on lipid profiles.
The effect of chronic alcoholism on various seminal parameters (sperm concentration, rate of forward motility, percentage of abnormal spermatozoa, lipid profiles of seminal plasma and spermatozoa) was studied together with the serum levels of testosterone and oestradiol. In chronic alcoholics there was a marked reduction in sperm concentration and in the rate of their forward motility, and increase in the number of spermatozoa with morphological abnormalities when compared to age-matched normal fertile subjects. Serum levels of testosterone were decreased while oestradiol levels were increased in chronic alcoholic men. Studies of lipid profiles showed a marked decrease in the total phospholipid concentration in spermatozoa, primarily in sphingomyelin, phosphatidyl choline and ethanolamine fractions. The cholesterol:phospholipid ratio in spermatozoa was increased in alcoholics. In the seminal plasma of chronic alcoholics, there was a decrease in total lipid, in glyceride glycerol and in free and esterified cholesterol. Of the phospholipid classes, sphingomyelin and phosphatidyl ethanolamine showed a significant reduction. In general, the present study provides evidence for the adverse effects of chronic alcoholism on serum hormones, sperm count, morphology, motility and seminal lipid profiles. These may be responsible for the fertility disorders common in chronic alcoholics.
