Influence of light on the plasma gonadotropin concentrations in the newborn rat
Experientia
|April 15, 1979
Abstract:
The physiological increase in plasma gonadotropin (LH and FSH) levels in newborn rats is indisputably influenced by light. Permanent illumination accentuates this increase, whereas darkness decreases it in 16-day-old female rats. In male rats of the same age, only permanent illumination was tested with the same results.
