Duration of the seminiferous epithelial cycle in the mature guinea pig: influence of unilateral orchiectomy

Abstract

The effect of unilateral orchiectomy on the seminiferous epithelial cycle in the mature guinea pig was studied. No significant change in the cycle duration was found. Thus, the previously reported hyperplasia of the contralateral testis is due to an increased number of cells entering the maturation process rather than to an acceleration of the cycle of seminiferous epithelium.
