The absence of the cremasteric reflex in an acutely painful testicle is most indicative of testicular torsion (the twisting of the spermatic cord of the testicle makes reflexive responses all but impossible). The cremasteric reflex normally causes elevation of the testicle by stroking the inner thigh. [1]
The testicles of calves, lambs, roosters, turkeys, and other animals are eaten in many parts of the world, often under euphemistic culinary names. Testicles are a by-product of the castration of young animals raised for meat, so they were originally a late-spring seasonal specialty, [ 1 ] though nowadays they are generally available year-round.

The corresponding system in females is the female reproductive system.
