it is suggested that since fsh acts only on the seminiferous epithelium , then the hypertrophy , hyperplasia , and functional enhancement of leydig cells after fsh treatment may be mediated by the secretion of one or more factors from the seminiferous tubules , providing additional evidence to support the view that gonadotropic regulation of testicular function is modulated by local interactions between the seminiferous tubules and the interstitial tissue .
