Fibril-associated spermatozoa internalized by macrophage

Video of fibril-associated sperm engulfed by macrophage

Macrophages labeled with a membrane dye (green) were incubated with sperm cells (red) for 3 h in the presence of semen fibrils and then imaged by confocal microscopy. This video demonstrates how semen fibrils can promote phagocytosis of sperm cells by macrophages. Video generated by Nargis Kohgadai and Mauricio Montano (UCSF and the J.
