title: Cholinesterase activity of seminal plasma and human spermatozoa in normal and infertile subjects.
abstract: Cholinesterase activity was determined in seminal plasma and human spermatozoa from 23 fertile volunteer subjects (N), 23 asthenospermic patients (A), and 25 oligoasthenospermic patients (OA). Cholinesterase activity determined in human seminal plasma for group N was 0.227 +/- 0.023 U/ml; for group A, 0.232 +/- 0.016 U/ml; and for group OA, 0.205 +/- 0.027 U/ml. The differences were not statistically significant. Sperm enzymatic activity in group N was 0.048 +/- 0.008 U per million sperms; in group A, 0.072 +/- 0.019 U per million sperms; and in group OA, 0.135 +/- 0.044 U per million sperms. These differences were not statistically significant.
