Do Hormonal Contraceptives in Teens Shape Altered Risk Assessment?

The researchers found that myelination, the formation of protective coating on axons projecting from the main body of brain cells, increased in rats given hormonal birth control compared to untreated rats, while the number of immune cells of the brain decreased. In behavior tests, the treated rats also showed signs of impulsivity. "We start the rats on hormonal contraceptives as soon as they go through puberty and give them throughout adolescence, and then do behavioral tasks at the cusp of adulthood," said Benedetta Leuner, co-senior author of the study and associate professor of psychology at Ohio State.
