What does cremasteric reflex tell you?

When the reflex is elicited by tactile stimulation of the thigh, the cremaster muscle contracts and draws the testis out of the scrotum toward the inguinal canal. Teleologically, the cremaster reflex protects the testis by drawing it out of harm’s way, but it may cause a normal testis to mimic an undescended testis.

What causes overactive Cremaster?

Cold temperature and anxiety are two factors that trigger what is known as the cremasteric reflex, or the pulling of the testicles upward toward the groin. However, excessive contraction can result in testicular retraction. There is no known cause for why the cremasteric reflex is exaggerated in certain boys.

What is the soleus H reflex?

Abstract. The Hoffmann (H-) reflex is an electrical analogue of the monosynaptic stretch reflex, elicited by bypassing the muscle spindle and directly stimulating the afferent nerve. Studying H-reflex modulation provides insight into how the nervous system centrally modulates stretch reflex responses.

How do I calm my cremaster muscle?

The cremaster muscle occasionally experiences painful spasms or cramps in adult males which can be chronic and debilitating. Treatment for these spasms ranges from minor surgery to injection with botulinum-a toxin to the regular application of heat to relax the muscle.

How does the cremaster reflex work in boys?

Cremasteric reflex. When the inner thigh is stroked, sensory fibers of the ilioinguinal nerve are stimulated. These activate the motor fibers of the genital branch of the genitofemoral nerve which causes the cremaster muscle to contract and elevate the testis. In boys, this reflex may be exaggerated which can occasionally lead to a misdiagnosis…

Where does the cremasteric reflex take place in the body?

This reflex is elicited by lightly stroking or poking the superior and medial (inner) part of the thigh – regardless of the direction of stroke. The normal response is an immediate contraction of the cremaster muscle that pulls up the testis ipsilaterally. The reflex utilizes sensory and motor fibers from two different nerves.

How old do you have to be to have cremasteric reflex?

It is difficult to determine the exact incidence of cryptorchidism because of the difficulty in differentiating truly maldescended testes from those that are retractile. All normal males older than 6 months of age have a cremasteric reflex that is thought to be protective for the testes.

Is the presence of the cremasteric reflex a differential diagnosis?

The presence of the cremasteric reflex does not eliminate testicular torsion from a differential diagnosis, but it does broaden the possibilities to include epididymitis or other causes of scrotal and testicular pain.
