Sperm abnormalities in retinitis pigmentosa.

Abstract

These results indicate that the sperm of patients with retinitis pigmentosa, particularly those with Usher's II, have an abnormal lipid composition that is associated with reduced motility. The possibility exists that these patients might have similar abnormalities in the DHA biochemistry of the retina. Sperm biochemistry and function may be a marker for this disease. A clinical trial of DHA in retinitis pigmentosa is suggested for future study.
