Fertilität reduzierende Wirkung langdauernder Noradrenalinbehandlung

Summary Albino rats of both sexes were treated with epinephrine and norepinephrine for 3 months, while the control animals received the same quantity of physiological NaCl. At the end of this period, the rats were allowed to multiply freely in each group. The number of litters was recorded in each case. While epinephrine did not alter the litter-rate, norepinephrine decreased it significantly. The effect of neural stress on reproduction and its relation to the adrenomedullar hormones is discussed.
