title: Efficiency of routine semen analysis to predict functional and structural integrity of human spermatozoa.
abstract: The study is to examine the ability of routine semen analysis to predict the functional and structural integrity of spermatozoa in in vitro conditions. Since large number of subjects were evaluated over a long period of time, the value of routine analysis to prognosticate the functional and structural integrity in the same sample was assessed. Routine semen analysis was done on 354 subjects. In the same sample, functional tests were carried out. The functional tests applied were hypoosmotic swelling test, test for acrosome intactness, nuclear chromatin decondensation test and sperm mitochondrial activity index. A scoring system was adopted for both routine and functional analysis. According to the scores obtained, the samples were categorized into fertile, subfertile and infertile. Analysis of the data indicated that efficiency of routine semen analysis was 38.13%. Prediction of functional integrity by routine analysis of semen specially in subnormal cases is only partly fulfilled. The study also indicates that functional tests are definitely indicated in cases with subnormal score.
