title: Clinical value of cell counts and indices in testicular fine needle aspiration cytology in primary infertility: diagnostic performance compared with histology.
abstract: OBJECTIVE
  To compare the diagnostic value of testicular fine needle aspiration (FNA) cytology with that of open biopsy in primary infertility and nonobstructive azospermia or severe oligozoospermia, to evaluate the reliability of percentage cell counts and cell indices.
  
  
  METHODS
  Thirty patients (21 azospermic and 9 severe oligozoospermic) who had samples for testicular FNA obtained from both testis (mean age = 28.7) and open biopsy were included in the prospective study. Primary infertility, history, complete physical examination, hormonal assay and testicular ultrasound data were evaluated. One case was excluded because of an unsatisfactory result in aspiration cytology. The percentage population of Sertoli cells and spermatogenetic cells, in addition to spermatic index, sertoli cell index and sperm-Sertoli cell indexes, was calculated. The statistical analysis was determined using the paired t test.
  
  
  RESULTS
  Progressively increasing values of the Sertoli cell index and progressively decreasing values of the sperm--Sertoli cell index were seen in maturation arrest, hypospermatogenesis and Sertoli cell-only syndrome. The difference between mean counts and indices in normal spermatogenesis and other histologic categories was statistically significant (p < 0.05).
  
  
  CONCLUSIONS
  Percentage cell counts and cell indices in testicular FNA significantly correlate with histological categories. In primary male infertility, testicular FNA can be performed instead of open biopsy.
