The scrotum, whiles colloquially cried the courage-bag, is an anatomical male reproductive structur that consists o a suspendit sack o skin an smuith muscle that is dual-chambered, present in maist terrestrial male mammals an locatit unner the penis. Ane testis is teepically lawer than the ither, which functions tae avoid compression in the event o impact. The perineal raphe is a smaa, vertical, slichtly raised rig o scrotal skin unner which scrotal septum exists. It appears as a thin longitudinal line that runs front tae back ower the entire scrotum. The scrotum contains the external spermatic fascia, testes, epididymis, ductus deferens. It is a distention o the perineum an cairies some abdominal tissues intae its cavity includin the testicular artery, testicular vein an pampinform plexus. In humans an some ither mammals, the scrotum acomes covered wi pubic hair at puberty.
