The perineal raphe is a visible line or ridge of tissue on the body that extends from the anus through the perineum to the scrotum (male) or the vulva (female). It is found in both males and females, arises from the fusion of the urogenital folds, and is visible running medial through anteroposterior, to the anus where it resolves in a small knot of skin of varying size.
This reflex is elicited by lightly stroking or poking the superior and medial (inner) part of the thigh—regardless of the direction of stroke. [1] The normal response is an immediate contraction of the cremaster muscle that pulls up the testicle ipsilaterally (on the same side of the body). The reflex utilizes sensory and motor fibers from ...
Cremaster is an involuntary muscle, responsible for the cremasteric reflex; a protective and physiologic superficial reflex of the testicles. The reflex raises and lowers the testicles in order to keep them protected. Along with the dartos muscle of the scrotum, it regulates testicular temperature, thus aiding the process of spermatogenesis. [1]

Testicular torsion may also be caused by trauma to the scrotum or exercise (in particular, bicycle riding); [10] however, only about 4–8% of cases are the result of trauma. [ 1 ] [ 2 ] There is thought to be a possible genetic basis for predisposition to torsion, based on multiple published reports of familial testicular torsion. [ 10 ]
A testicle cuff is a ring-shaped device that can be placed around the scrotum between the body and the testicles. When it is closed it prevents the testicles from passing through. A common type of testicle cuff consists of two connected cuffs, one around the scrotum and the other around the base of the penis.
In the scrotum, the line is located over the internal scrotal septum that divides the two sides of the sac and is densely occupied by nerve fibers. [8] The raphe may become more prominent and darker when the scrotal sac tightens due to contractions. Behind the scrotum, it continues as the perineal raphe.
