AggressionTestosterone can heighten activity in limbic structures (amygdala, hypothalamus) that control threat responses. Enhanced signaling through these pathways can make a person more reactive to perceived challenges or threats, producing an aggressive mood.
Low‑mood / depressive feelingsElevated testosterone may alter monoaminergic circuits (e.g., serotonin and dopamine pathways). If the balance of these neurotransmitters shifts, it can dampen the reward system and reduce overall affect, leading to a feeling of sadness or low motivation.
General irritability or mood swingsFluctuations in hormone levels can lead to changes in neuronal excitability across cortical networks, making emotional regulation more difficult and producing rapid shifts between calmness and agitation.
These effects would be more likely if the dosage is high enough that testosterone levels exceed normal physiological ranges for men.
