Brain steroids make good dads

Testosterone in males is generally associated with aggression and definitely not with good parenting. Insights from a highly social fish can help understand how other androgenic steroids, like testosterone, can shape a male's parenting skills, according to a recent Georgia State University research study.

Once bluebanded gobies become fathers, they stay close to the developing eggs, vigorously fan and rub them until they hatch, and also protect them from mothers who would eat them. By injecting a series of chemicals into the brains of these fathers, the research team temporarily altered their brain androgens and also their level of parental care. As a result, the researchers found that brain androgens actually promote good parenting.
