| cremasteric reflex |
stimulation of the skin on the front and inner side of the thigh retracts the testis on the same side. The presence of this reflex indicates integrity of the first lumbar nerve segment of the spinal cord or its root; absence indicates damage of the first lumbar nerve segment or its root or lesion of the corticospinal tract. Cf. Geigel's r. and hypogastric r.
