Background & objective: Regarding the importance of histologic examination of testicular biopsy for clinical planning of infertility, the current study was conducted to compare 2 separate histologic examination of testicular biopsy. Also, some cases with known fertility outcome were followed and their histological patterns were also compared with those of the outcome. Methods: The current study was conducted on testicular biopsies of 924 males evaluated for infertility from 1990 to 2013, retrieved from the archive of pathology department of Shahid Beheshti Hospital, Babol, Northern Iran. All slides were reviewed by a pathologist unaware of the original results. Data including age, histological pattern of spermatogenesis (pure and mixed), smoking, and the history of ejaculatory duct obstruction were retrieved from the pathology archive. In some cases, the outcome was also compared with that of the histological pattern. All analyses were executed using SPSS version 22 statistical software. To analyze the data, t test, Chi-square test, one-way ANOVA, and the least significant difference (LSD) test were used. Results and Conclusion: Out of the 924 testicular biopsies, 34 (3.7%) cases had different reports from original reading. LSD analysis indicated Sertoli cell only syndrome (SCO) as the most common histological pattern. There was a significant difference between the mean age of cases with SCO and that of the ones with hypospermatogenesis (HYPO) (P =0.03). Obstruction was higher in pure pattern (P=0.04). The pregnancy rate was higher in the wives of males with obstructive infertility than the ones with non-obstructive infertility. SCO was the most common histological pattern of testicular biopsy during 23 years. Pure patterns were more than mixed patterns, and the mean age was lower in mixed patterns. Also, pure patterns were the most common findings in the cases with obstructive infertility.
