'''Testicular atrophy''' is relatively common change seen in undescended [[testes]]. It is also known as '''atrophic testis''' and '''atrophy of the testis'''. | |||

*Microscopic appearance identical to ''cryptorchidism'' (undescended testis).<ref name=Ref_PCPBoD8_506-7>{{Ref PCPBoD8|506-7}}</ref> | |||

*Thickening of seminiferous tubule basement membrane. | |||
*Intertubular fibrosis. | |||
*Decreased sperm/no sperm present. | |||
Notes: | |||
*End-stage testicle - only has Sertoli cell within the seminiferous tubules. | |||
*Sertoli cells may have a cytoplasm with eosinophilic granules (lysosomes). This is a nonspecific finding described in several contexts.<ref name=pmid1672120>{{Cite journal | last1 = Nistal | first1 = M. | last2 = Garcia-Rodeja | first2 = E. | last3 = Paniagua | first3 = R. | title = Granular transformation of Sertoli cells in testicular disorders. | journal = Hum Pathol | volume = 22 | issue = 2 | pages = 131-7 | month = Feb | year = 1991 | doi = | PMID = 1672120 }}</ref> | |||

===Micro=== | |||
The sections show seminiferous tubules surrounded by thick hyaline sleeves. In a large number of sections only Sertoli cells are found in the tubules. | |||
In some sections poorly defined paucicellular tubular structures reminiscent of seminiferous tubules composed of hyaline material are present; these probably represent obsolete seminiferous tubules. Focally, fibrosis is seen without definite tumour outlines. There is no significant inflammation. The rete testis is identified. | |||
Rare seminiferous tubules have spermatid within. The germ cells seen do not have appreciable nuclear atypia. | |||
Small Leydig cell clusters are seen in some sections. | |||
