incubations for sperm capacitation and egg fertilization in different media containing the various hexoses showed that rat epididymal spermatozoa could be partly capacitated without hexose , that d-glucose , d-mannose or d-galactose but not d-fructose is effective for sperm capacitation and that only d-glucose and d-mannose supported penetration of eggs in vitro .
