[Prostaglandin E in vaginal smears--a possibility for sperm detection in azoospermia].
The identification of seminal traces is exceptionally difficult, if the semen of the assailant is azoospermic. The evident value of prostatic acid phosphatase (PAP) activity must be evaluated in such cases with caution. In a murder investigation of a 13 year old girl a positive PAP reaction was found in vaginal swabs and in her underpants. Spermatozoa could not be found. Using the gas-chromatographic method, described by Douse (1985) the presence of prostaglandin E could be demonstrated in the swabs as well as in the crotch of the underpants. The offender was found to be a man with azoospermia, who admitted intercourse but with the consent of the victim. The E prostaglandins are mainly synthesized in the vesiculae seminal and seen to be specific for semen. Swabs taken from mouth and rectum showed negative reactions for prostaglandins in this case. Prostaglandins could never be detected in vaginal swabs taken at least 7 days after intercourse. Conversely Douse could detect prostaglandins in swabs up to 58 hours after intercourse. Apparently the prostaglandin detection by Douse provides a suitable alternative besides to the quantitative and immunological PAP detection or the immunological detection of the protein p 30.
