A. Valenciasanchez et al., AMINE NEUROTRANSMITTER LEVELS IN MALE AND FEMALE RATS THROUGH DEVELOPMENTAL PERIODS, Archives of andrology, 39(1), 1997, pp. 79-83
Monoamines (MA) such as dopamine (DA), norepinephrine (NE), and 5-hydr
oxytryptamine (5-HT) are now generally regarded as widely distributed
and essential endogenous mediators contributing to the integration of
reproductive physiology. MA measured in the hypothalamus tissue of mal
e and female rats aged 1 to 90 days showed its own characteristic deve
lopment pattern. Significant differences were observed at 5, 15, and 9
0 days of age in NE mean levels and at all ages except for 3 days of a
ge in 5-HT mean levels. In contrast, no sex differences were seen in D
A mean levels.
