Interpretation of testicular biopsies of the infertiles

To identify different histological feature of testis of infertile males and classify the types into well defined groups to use Johnsen Score for grading of the degree of spermatogenesis, to find out age distribution and to compare the results obtained with similar studies. During 12 months period from January 2017 to January 2018,100 consecutive testicular biopsies were collected from infertile males. After being immediately fixed in Bouin's solution, for at least 24 hours, they were embedded in paraffin and 4 micron sections were cut and stained by hematoxylene and eosin. Elastic Van Gieson stain was used when indicated to show the fibrosis. Hundred infertile males were included in this study, (97) had primary infertility and only (3) had secondary infertility,. Eighty six had azoospermia and (14) had severe oligospermia . The youngest male was (18) years old and the oldest was ( 43 ) years old. The mean age of the males with primary infertility was ( 28.19) years and that for the secondary infertility group was (33) years. Out of the total, (33) were between the ages of (30 – 34) years. Primary infertility is more common than secondary infertility amongst those seeking testicular biopsy. Sertoli cell only syndrome was the commonest histologic finding in our community. The majority of infertile males were in the 4th decade. Johnsen score 2 is the most prevalent score found among all patients.
