ABSTRACT Symmetry exists as a morphological/Anthropometrical feature to establish the body axes during embryonic.Poroscopy (the study of pore channels sweat glands) is a method for identification of individuals, in this method, the properties of pore channels of sweat glands are compared with each other, from different aspects. Changes in asymmetry are a capacity versus adaptive genetic factors. The pore characteristics are constant, unchanging and unique and in the case of inadequate information collected by studying skin line properties poroscopy can also be used. Analysis of skin lines and pores, sweat glands channel are being used in medicine for diagnostic identification and early recognition of many diseases. Since, different methods used in poroscopy so far are not very liable, in this innovative method attempts were made to investigate the no and symmetry of pores of sweet glands in the first clause of the left and right thumbs. Also, the formation of pore channels of sweat glands in men in the age group of zero to 60 years were studied and compared. This analytical study was performed in observational approach of random samples of healthy men raised in Mashhad. After obtaining informed consents and completed questionnaires from 25 babies , 11 children , 14 adolescents , 25 young and 25 middle-aged men , the print of the first paragraph thumbs ( right and left 1 3 ) and refer fingers of two hands (right: Number 2 left: No. 4 ) on the coverslip were recorded using a digital microscope (Dino-Lite-plus AM313) with 65 × magnification. The fingerprints and pores of sweat glands is calibrated using the software MIP4.2 Full Image. The data analysis was performed with Statistical Analysis Software Spss21 .The results showed that the size and the average number of channels and pores of sweat glands in the left and right hand thumb and index finger were reduced by age, in each case (P<0.05). The amount of overlap asymmetry between the pore channels of sweat glands on the right and the left thumb in babies , children, adolescents , young and middle-aged were 13/48 , % 1/36 , % 65 , % 65 , % 4/32 and for the refer finger were % 83/49 , % 75 , % 66/66 % 66/41 % 83/45 respectively.
