The prostate in pregnant and non-pregnant Praomys (Mastomys) Natalensis at the subcellular level.

The prostate of the pregnant Praomys appears more active than that of the non-pregnant Praomys. At the light microscopic level, the most obvious features are heightening of secretory cells and increased secretory product in acinar lumina. Apparent at the electron microscopic level are an increase and dilation of the rough endoplasmic reticulum, numerous scattered secretion granules, and a dilated Golgi apparatus. Therefore, stimulation of the gland is evident upon cytological evaluation and this increased activity may be due to the direct or indirect effects of androgenic stimulation.
