Behavioral Evaluation of Male and Female Mice Pups Exposed to Fluoxetine during Pregnancy and Lactation

Abstract

In male pups, exposure to FLX decreased ambulation at postnatal day (PND) 40 and tended (p=0.07) to increase the latency to the first attack in the intruder-resident test at PND 70, suggesting decreased impulsivity. In female pups, FLX exposure increased immobility time in the forced swimming test at both PND 30 and 70, which is interpreted as depressive-like behavior. In conclusion, our results suggest that maternal exposure to FLX during pregnancy and lactation results in enduring behavioral alterations in male and female pups throughout life.
