Contraceptive effect of sperm-agglutinating factor isolated from Staphylococcus aureus in mouse.

摘要

Objective. To investigate the contraceptive effect of sperm-agglutinating factor (SAF) isolated from Staphylococcus aureus in mouse. Design. Experimental study performed with LACA mice obtained from the Central Animal House, Panjab University, Chandigarh, India. Setting. In vivo studies conducted in the Department of Microbiology, Panjab University, Chandigarh, India. Population. Sixty female and 18 male mice were used for the studies. Methods. Mice sperm-S. aureus agglutination, scanning electron microscopy (SEM), in vivo studies in mice. Main outcome measure. Contraceptive efficacy of SAF. Results. S. aureus readily adhered to and agglutinated mouse spermatozoa. By SEM, S. aureus adherence was observed on sperm head as well as sperm tail. SAF was found to be causing 100% fertility inhibition in mouse with no effect on vaginal epithelium. Conclusions. Sperm-agglutinating factor has been found to have a potential as a contraceptive agent.
