Effect of water immersion on seminal stains on cotton cloth

Reports on identification of seminal stains and spermatozoa on washed clothing are available. However, their detection on such clothing seems to depend on the washing material and the procedure adopted. It is reported here that prolonged immersion in water does not affect the detection of stains and spermatozoa. Results of experiments on water-immersed cotton clothing from 12 to 144 hours of water immersion are presented here. It is seen that intact human spermatozoa could be detected on such material even at 120 hours.
