Subsequent to early studies that established the pheromonal qualities of male urine to synchronize estrous cycles of laboratory mice [ 2 ] , sexual maturation in female mice was shown to be accelerated by male pheromones [ 3 ] and retarded by female pheromones [ 4 ] . Pheromonal induction of first estrus in juvenile females has been reported in a variety of other mammals including prairie voles [ 5 ] , pigs [ 6 ] , and opossums [ 7 ] .
Juvenile females in this study were exposed to male scentmarks from the age of 90 days, but they did not express first estrus until 130 days, much longer than the average of 7 days required for pheromonal induction of estrus in adults.
Plasma concentrations of estradiol in opossums are low (<15 pg/ml) during anestrus and are elevated (>20 pg/ml) only during estrus [ 15 ] . Mean plasma estradiol concentrations as high as 58 pg/ml have been reported in estrous females [ 25 ] , but a gradual increase in circulating estradiol during pheromonal induction of estrus in opossums has not been described.
Future studies that control for estrogenic effects of ovarian activation, food availability, and body growth during the relatively protracted period of pheromonal induction of first estrus offer promise for extending our understanding of the role of social and environmental signals on body growth and sexual maturation.
The gray short-tailed opossum ( Monodelphis domestica ), a small (60-150 g) marsupial native to scrub forests of southeastern Brazil, provides new opportunities for study of olfactory communication and pheromonal activation of reproduction.
