A Study of the Effect on Sperm Motility by Trichomonas Vaginalis and Gonococci

  • 1Department of Urology, Chungnam National University, Daejeon, Korea.


It was suspected that a GUT infection could be a possible cause of infertility. This study was carried out to investigate the effect of Trichomonas vaginalis and Gonococci on sperm motility. Human fresh spermatozoa from 50 healthy medical students were mixed and diluted with Trichomonas vaginalis and Gonococci. 30 specimens to Trichomonas vaginalis and 20 specimens to Gonococci were exposed with varying concentration from 10(4) to 10(6) organisms/ml of broth, respectively. Spermatozoal motility scale devised by Emmens was checked at serial time of hours in vitro. The following results were obtained: 1. The sperm motility of control groups among pure semen, semen with normal saline and semen with broth solution were no significant differences. 2. A significantly decreased sperm motility ensued in Trichomonas vaginalis experimental groups, 106 organisms/ml and broth extract contained metabolite, than control group. 3. There were no significant differences between control groups and experimental groups in Gonococci.
