Abstract

This study was carried out to investigate the effect of Mycoplasma on sperm motility. It was suspected that a GUT infection due to Mycoplasma could be a possible cause of infertility. Human fresh spermatozoa from 57 healthy medical students were mixed and diluted with Mycoplasma groups. 37 specimens to T-mycoplasmas and 20 specimens to M. hominis were exposed with varying concentration from 10,000 to 1,000,000 colonies/ml of broth, respectively. Spermatozoal motility scale devised by Emmens and pH by pH paper were checked at serial time of hours in vitro. The following results were obtained. 1. There is no significant effect on sperm motility in pH change by Mycoplasma. 2. The sperm motility of control groups among pure semen, semen with normal saline and semen with broth solution were no statistically significant differences (p>0.05). 3. The statistically significant decreased sperm motility was watched in T-mycoplasmas experimental groups than that of control groups. The motility was much decreased with higher concentration of organisms (p<0.05). 4. The statistically significant decreased sperm motility was also watched in M. hominis experimental groups than that of control groups (p<0.05) The motility was much decreased with higher concentration of organisms.
