Photoperiodic influence on the morphology and the androgen receptor level of the ventral prostate gland and seminal vesicles of the Djungarian hamster (Phodopus sungorus).
The influence of long (light:darkness LD 16:8) and short (LD 8:16) photoperiods on the morphology of the ventral prostate gland and the seminal vesicles of the Djungarian hamster was investigated. At LD 8:16, the wet weight of the glands was reduced to 15-20% of the values found in animals living in LD 16:8 conditions, the protein content was reduced to 3-4%. The glands showed distinct signs of atrophy and inactivity under short-day conditions. The androgen receptor levels were determined in both accessory sex glands. The receptor levels were comparable in both glands; the absolute values related to the whole glands remained about constant in animals living in long and short photoperiods despite a reduction of the androgen levels in short photoperiods.
