[Personal experience with the detection of sperm using leucylaminopeptidase]

The detection of leucylaminopeptidase (LAP) has been carried out in human male and female sexual organ tissues and in vaginal smears through the use of histochemical methods. On the ground of the performed experiments it is possible to prefer the statement that the finding of a positive result of LAP activity testing might be used as a complementary method for obtaining indirect proof of the presence of sperm in vaginal smears. LAP activity may be demonstrated until the term of twelve hours following sexual intercourse.
