Examples of "hypospermatogenesis"
Testicular biopsy would confirm the absence of spermatozoa . Seminal plasma protein TEX101 was proposed for differentiation of Sertoli cell-only syndrome from maturation arrest and hypospermatogenesis.
With the goal of replacing the more invasive biopsy histology with FNA cytology, a simple, working classification schema for testis FNA cytology has been proposed that is based on pattern recognition. The identified patterns represent histological diagnoses but are based on relative numbers of three easily identified germ cell types on cytologic assessment: primary spermatocytes, spermatids, and spermatozoa. The various germ and Sertoli cells are not precisely counted but are loosely quantified by assessing the relative number of cells present. In this way, a standard ratio of cell types for comparison to Sertoli cell density is created. The FNA patterns for hypospermatogenesis, Sertoli cell-only, early maturation arrest, and late maturation arrest show different ratios of these three cell types relative to normal spermatogenesis and are relatively easy to categorize in this way. In a review of 87 patients with paired FNA maps and biopsy, this cytologic classification was observed to be reproducible and accurate. Histologic categories determined by FNA patterns correlated well with open biopsy histology across all patterns in 94% of cases. FNA cytology was also able to completely describe mixed histologies in 12 of 14 cases. Thus, the determination of histology by FNA cytology pattern is accurate and suggests that the more invasive testis biopsy is unnecessary to diagnose states of infertility. Alternatively, it is possible that newer processing methods can be applied to testis FNA cytology specimens to concentrate and prepare seminiferous tubules for sectioning similar to classic histologic preparations. Either way, testis cytology is a viable alternative to histology in the evaluation of male infertility.
