Correlation between spermatozoon numbers in spermiogram and seminiferous epithelium histology in testicular biopsies from subfertile men.
A new method for correlating testicular biopsies and spermiograms is proposed. The number of spermatogonia, round spermatids, and elongated spermatids per cross-sectioned tubule were calculated in the testes from 33 subfertile men and in 10 control normal testes. According to these quantitations, the testes in subfertile men were classified as testes with maturation arrest of spermatogenesis, testes with hypospermatogenesis, and testes with associated maturation arrest and hypospermatogenesis. A power regression curve correlating the number of elongated spermatids and sperm numbers in the spermiogram was performed.
