Relatively larger numbers of both precapacitated and postcapacitated bull sperm migrated toward the <jats:styled-content style=\"fixed-case\">BFF<\/jats:styled-content> (0.1%). The ability of the 0.1% <jats:styled-content style=\"fixed-case\">BFF<\/jats:styled-content> to attract sperm probably affected both the normal artificial insemination (<jats:styled-content style=\"fixed-case\">AI<\/jats:styled-content>) fertility sperm and the poor <jats:styled-content style=\"fixed-case\">AI<\/jats:styled-content> fertility spermatozoa.
