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]
The cremasteric reflex may be absent with testicular torsion, upper and lower motor neuron disorders, as well as a spine injury of L1-L2. It can also occur if the ilioinguinal nerve has accidentally been cut during a hernia repair. [4] The cremasteric reflex can be helpful in recognizing testicular emergencies.
At the beginning of the video, his genitals are non-aroused: the scrotum is loose, the testicles hang low away from the body, and the penis (not shown) is flaccid. During arousal, the the skin of the scrotum tightens and contracts, the testicles are pulled upward toward the body, and the penis (not shown) becomes erect. The process is ...
Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. [1] Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. [1]

The cremasteric reflex (elevation of the testicle in response to stroking the upper inner thigh) remains normal. [1] This is a useful sign to distinguish it from testicular torsion. If there is pain relieved by elevation of the testicle, this is called Prehn's sign, which is, however, non-specific and is not useful for diagnosis. [13]
The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant.
