15.9 Atrophied human testis

Version française

Section of the testis of a hypophysectomized adult human.

The atrophied seminiferous tubules show a thickened limiting membrane (M) composed of connective tissue fibres.

The regressed epithelium that fills the rest of the tubule is composed mainly of regressed Sertoli cells (S) and a few spermatogonia (Sg).

In the interstitial spaces (*) the endocrine Leydig cells are also atrophied in the absence of stimulation from the gonadotrophic hormones (compare with the Leydig cells in a normal human testis in Figure 15.16).
