title: Modifications in the seminal protein pattern and concentration among infertile men.
abstract: Lower concentrations of protein observed in semen of infertile men were mostly due to absence of vesicular proteins with higher isoelectric pH above pH 8.3. Two to four proteins with lower isoelectric pH showing electrophoretic mobility and originating both from seminal vesicle and prostate were absent in infertile semen samples. Concentrations of such proteins among oligozoospermic and azoospermic samples with complete maturation arrest and Sertoli cell only syndrome decreased mainly towards cathode, whereas, in vasectomized azoospermia the number of protein bands decreased both towards cathode and anode, though the concentration decreased mainly in the anodic proteins.
