SUMMARY The anatomical, histological and morphological structure of the fasciomuscular tube which surrounds the spermatic cord was studied in 20 cadavers of full mature neonatal foetal death and in 10 varicocele patients. The spermatic and cremasteric fasciæ are composed of elastic fibres impregnated with collagen, and act as an elastic stocking to the cord. Together with the cremasteric muscle they form a fasciomuscular pump which may play an important role in the hæmodynamics of the venous return from the cord. Tubal atrophy and subluxation were found in varicocele. Tubal subluxation resulting in inefficiency of fasciomuscular pumping mechanism is discussed as an ætiological factor in varicocele.
