Changes in the weights of the accessory sex organs in male CD/IGS rats (Rattus norvegicus) after castration.
This study was designed to detect time-course changes in the weights of accessory sex organs after castration. Crj:CD(SD) IGS rats (Rattus norvegicus) were castrated at age of 6-weeks and sacrificed within 14 days of the procedure. The ventral prostate, vesicular gland, bulbospongiosus/levator ani muscle, glans penis and bulbourethral glands were then weighed. The ventral prostate and vesicular gland had significantly decreased in weight 8 and 6 days after castration, respectively. The other organs did not decrease in weight significantly between time periods though there was an overall decrease in weight.
