title: Effects of FSH and LH administration on the testes and seminal vesicles.
abstract: Weight increases in the testes of pre-pubertal rodents when FSH was administered were revealed by histological observations to be a result of seminiferous tubule lengthening. LH administration effected a sex accessory gland weight increase (seminal vesicles) but there were no apparent testicular effects. The serum androgen level, in response to increased LH administration, showed a continuous decrease in concentration although there was a significant seminal vesicle weight increase. The evidence presented in this paper leads us to postulate that LH has a sensitizing effect on androgen dependent tissues in the pre-pubertal rodent.
