cremasteric reflex

The cremaster reflex is a kind of shallow reflex in the human nerve reflex. When the physical examination is performed, the blunt-headed bamboo stick is used to lightly cut the skin on the inner side of the femoral upper and lower sides, which can cause contraction of the ipsilateral cremaster muscle and lift the testicle. . The examiner used a cotton swab to gently stroke the skin above the inside of the thigh of the male patient from the bottom up. Normally, the ipsilateral testicles are immediately lifted. If there is no such reaction or the reaction is slow, the cremaster reflex is weakened or disappeared. Because emotional stress can affect the results of cremaster reflex, patients do not have to be too nervous and feel shy when doing cremaster reflex examination to prevent errors in the results. Basic Information Specialist Category: Neurological Classification: Other examinations Applicable gender: whether the male is fasting: not fasting Tips: Clean the penis and testicles before cleaning and keep the penis and testicles clean. Normal value Normally, the ipsilateral testicles are immediately lifted. Clinical significance Abnormal results: cremaster reflex is a normal shallow reflex. If the bilateral cremaster reflex is weakened or disappeared, it suggests that there is lumbar spinal cord injury, which can also be seen in the elderly. Attenuation or disappearance of one side of the cremaster can be seen in pyramidal lesions, and can also be used in the diagnosis of certain surgical conditions (such as oblique hernia, varicocele, etc.). People in need of examination: patients with suspected lumbar spinal cord injury and pyramidal tract lesions. Precautions Pre-inspection contraindications: Clean the penis and testicles before cleaning and keep the penis and testicles clean. Requirements for examination: Because emotional stress can affect the results of cremaster reflex, patients should not be too nervous and feel shy when doing cremaster reflex examination to prevent errors in the results. Inspection process The examiner used a cotton swab to gently stroke the skin above the inside of the thigh of the male patient from the bottom up. Normally, the ipsilateral testicles are immediately lifted. If there is no such reaction or the reaction is slow, the cremaster reflex is weakened or disappeared. Care should be taken to distinguish it from the scrotal contraction. The cremaster reflex is not accompanied by scrotal contraction. When touching the skin of the patient's scrotum, it causes the scrotal peristaltic contraction and is a scrotal reflex. Not suitable for the crowd Inappropriate population: patients with severe testicular loss. Adverse reactions and risks Nothing.
