Testosterone: Action, Deficiency, Substitution
Evaluation of the spermatogenic process can be qualitative or quantitative.
Qualitatively normal spermatogenesis refers to the presence of all germ cell types
and spermatogenic stages; whereas quantitatively normal spermatogenesis
refers to ...

Comparative Reproductive Biology
The demarcation lines between the adjacent stages are not quite distinct. A cross
section of tubules usually shows three stages of spermatogenesis. Some regions
of the tubules may lack one or even two generations of spermatogenic cells.
Heide Schatten, Gheorghe M. Constantinescu, 2008

Functional Anatomy and Physiology of Domestic Animals
A spermatogenic wave that involves a 12-day cycle is illustrated in Figure 14-17.
The wave involves a sequence of stages beginning with the less advanced
stages in the middle of the loop to progressively more advanced stages nearer
the ...

The Laboratory Primate
The spermatogenic capacity of the testis is dependent on the number of Ap
spermatogonia, which, in turn, depends on the expanding population of Sertoli
cells since each Sertoli cell can support only a limited number of germ cells (Orth
et al., ...
