Normal testicular tissue elasticity by sonoelastography in correlation with age

PurposeThis research aimed to study the correlation between the normal testicular tissue elasticity as detected by real time sonoelastography with the age.Materials and methodsThe study was conducted upon 63 adult healthy volunteers. Each volunteer was subjected to real time sonoelastography measuring the strain ratio of testicular tissues and their elasticity scores.ResultStrain ratios of the examined testes ranged from 0.27 to 0.38, with a mean strain of 0.33 and a standard deviation of 0.03. Elasticity score of the examined testes included ES1 in 62 testes (49%), ES2 in 58 testes (46%) and ES3 in 6 testes (5%). No ES4 or ES5 was elicited in this group. High negative correlation is found between the age and both the testicular volume and the strain ratio, while there is no correlation between age and the elasticity score of testes.ConclusionNormal testicular tissues as studies by sonoelastography show strong correlation between the age and the testicular volume as well as the strain ratio.
