Multilayer germinal epithelium was observed with several types of
spermatogenic cell (Figure-2)
Effects of testosterone on
spermatogenic cell populations in the adult rat.
The effect of exercise seems to be more prone in protecting seminiferous tubules (
spermatogenic cell lineage and Sertoli cells) than Leydig cells.
Effects of pomegranate juice consumption on sperm quality,
spermatogenic cell density, antioxidant activity and testosterone level in male rats.
Intense staining was observed in almost all the
spermatogenic cell types (from spermatogonia to elongated spermatids) in testis sections from CP-treated rats.
The gene encodes a RNA binding protein that localizes to the nucleus of all
spermatogenic cell types (4,20).
A study demonstrated in 1983 that
spermatogenic cell was the radiosensitive tissue in testis and constituted 70% of the normal testicular weight.25 Therefore, it seems logical that germ cell loss would lead to a decrease in testicular mass, and it explains the volume loss with radiation in our model.25 Testosterone had no statistically significant effect on testicular volume within the two- month study period.
Spermatogenic cell series in seminiferous tubule wall, spermatogonium, primary spermatocytes, spermatid cell, and Sertoli cell were found normal and comparable to the untreated control (Figure 4a-d).
In testicular hypoplasia and cryptorchidism, the seminiferous tubules had reduced luminal diameters with complete absence of
spermatogenic cell maturation stages.
