Background: The literature regarding the quality of the sex life in adult males after circumcision, due to phimosis, is scarce and sometimes contrasting. This could be due to comparisons of a nonhomogeneous distribution of the clinical variables of men who have undergone circumcision. Objective: The objective of this study was to evaluate the distribution of the clinical variables in the adult male population who had circumcision for phimosis, and to propose a clinical classification of the phimosis to characterize it in adult males in more homogeneous sub-groups for the common clinical variables. Materials: A population of 244 adult male patients with phimosis was evaluated retrospectively. The mean age was 50.7 years. Each patient was classified according to the most common clinical variables. The variables that make up this classification of the phimosis were: Position (P1-2) to indicate if phimosis is present when the penis is at rest (P2) or only during an erection (P1); Grade (G 0-4) in relation to the extent of glans visibility; Complexity (Co 0-4) of comorbidities; Timespan (T 1-10) of the phimosis. Results: The distribution of the variables was the following: Position P1:30.73%, P2:69.26%; Grade G0:30.73%, G1:23.77%, G2:27.45%, G3:12.29%, G4:5.73%; Complexity (associated penile comorbidities): C0:48.36%, C1:4.5%, C2:0.8%, C3:43.03%, C4:3.27% Timespan: 57.78% of the patients had phimosis for less than a year; 18.03% between 1 and 2 years; 11.88% between 2 and 10 years; and 12.29% for more than 10 years. Conclusions: The distribution of the clinical variables in the adult male population who underwent circumcision due to phimosis was not homogeneous regarding the appearance, severity, comorbidity, and timespan. This non-homogeneity could explain, in some cases, the contrasting results regarding the quality of sex life after circumcision in the literature. The proposed classification can offer an objective tool for researchers and clinicians group the patients into more homogeneous subgroups.
