Throckmorton's reflex

Throckmorton's reflex is a medical term referring to a reflexive movement of the penis in response to physical or neurological stimulation. This reflex is named after the American urologist, Dr. James Throckmorton, who first described it in the early 20th century.

Overview[edit | edit source]

The Throckmorton's reflex is a normal physiological response that occurs in males. It is often observed during physical examinations, particularly during the examination of the genitourinary system. The reflex is triggered by the stimulation of the perineal nerve, which is a branch of the pudendal nerve. This nerve innervates the skin of the penis and the scrotum, as well as the muscles of the perineum.

Clinical significance[edit | edit source]

The Throckmorton's reflex can be used as a diagnostic tool in the evaluation of certain neurological conditions. For instance, an absent or diminished reflex may indicate damage to the perineal nerve or the sacral spinal cord, which could be due to conditions such as spinal cord injury, diabetes mellitus, or multiple sclerosis. On the other hand, an exaggerated reflex may suggest a hyperactive nervous system, which could be seen in conditions like anxiety disorders or hyperthyroidism.
