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

Features:<ref name=Ref_PCPBoD8_506-7>{{Ref PCPBoD8|506-7}}</ref>
*Thickening of seminiferous tubule basement membrane.
*Intertubular fibrosis.
*Decreased sperm/no sperm present.
 
Note:
*End-stage testicle - only has Sertoli cell within the seminiferous tubules.

TESTICLE, RIGHT, ORCHIECTOMY:
- ATROPHIC TESTICLE.
- NEGATIVE FOR INTRATUBULAR GERM CELL NEOPLASIA.
- NEGATIVE FOR MALIGNANCY.

====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.
 
Numerous small Leydig cell clusters are seen in some sections.
