Summary
[edit]| Description |
English: Real-time demonstration of the automatic adjustments of the scrotum and testicles of an adult male during the process of sexual arousal. The subject is a 27-year-old healthy Caucasian male. 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 physiologically similar when transitioning from a hot to cold temperatures, or from a state of emotional relaxation to anger or fear. It can be observed throughout the video that one testicle hangs lower than the other; this is completely normal and natural. Also visible is the increased prominence of the central scrotal raphe as the scrotum contracts, another natural feature. The bilateral effects of the arousal process can be compared with the unilateral effect of the cremasteric reflex and with the manual retraction of the testicles into the inguinal canals. |
