Katecholaminfreisetzung

Katecholaminefrigide, also known as catecholamine-induced frigidity, refers to a condition characterized by a temporary loss of sexual desire or arousal in response to elevated levels of catecholamines, a group of hormones and neurotransmitters that include adrenaline (epinephrine), noradrenaline (norepinephrine), and dopamine. This phenomenon is often observed in high-stress or adrenaline-driven situations, such as intense physical exercise, extreme sports, or emotional distress.

The physiological basis for catecholamine frigidity lies in the body’s fight-or-flight response, where heightened catecholamine levels prioritize energy toward survival mechanisms rather than reproductive functions. Dopamine, in particular, plays a dual role: while it typically enhances arousal and motivation, excessive levels can paradoxically suppress sexual interest by overwhelming the brain’s reward system. Similarly, adrenaline and noradrenaline, which increase heart rate and blood pressure, may divert blood flow away from genital regions, further reducing arousal.

This condition is not a medical disorder but rather a normal physiological response in certain contexts. It is more commonly reported in women, though men may also experience diminished sexual function under extreme stress. Factors such as anxiety, fatigue, or intense focus on physical performance can exacerbate the effect. Unlike persistent sexual dysfunction, catecholamine frigidity is typically short-lived and resolves once the stressor is removed or catecholamine levels return to baseline.

While not well-documented in clinical literature, anecdotal reports suggest that individuals with high baseline catecholamine sensitivity may be more prone to experiencing this phenomenon. Understanding this response can help mitigate unnecessary concern, particularly in athletes or individuals engaged in high-pressure activities where stress-induced physiological changes are expected. If persistent sexual dysfunction occurs outside of such contexts, medical evaluation is recommended to rule out underlying conditions.
