blood sera of humans , rats , goats , and buffalo have been shown to possess a forward motility-stimulating factor ( fmsf ) that markedly stimulated goat cauda epididymal sperm forward motility , as assayed by a microscopic method in the presence of epididymal plasma ( 1.2 mg protein/ml ) that had sufficient anti-sticking activity to eliminate the possibility of cell-sticking artifacts in motility assays .
