Abstract:
This study was carried out to investigate the effect of sperm motility to some bacteria which were possible cause of infertility by genitourinary tract infection. Human spermatozoa, from 42 cases of healthy medical student, were exposed to E. coli (30 cases) and Staphylococcus aureus (12 cases) varying dilutions from 10(4), 10(5), 10(6) colonies/ml of normal saline and broth solution. Spermatozoal numerical motility scale devised by Emmens was checked at the serial time of hours in Vitro. The following results were obtained: 1. Sperm motilities of control groups among pure semen, semen with normal saline, semen with broth solution and semen with broth extract contained endotoxin were no significant differences. 2. A significantly decreased sperm motility ensued in E. coli experimental groups than control group. And the more concentrated bacteria the more significant decrease of sperm motility was observed. 3. There were no significant differences between control group and experimental groups in Staphylococcus aureus.
