How does dopamine affect sex?

Dopamine plays a significant role in sexual behavior, affecting both motivation and the physical response. Here's a summary based on what Andrew Huberman has shared:

1. Motivation and Craving: Dopamine is crucial for the anticipation and craving aspect of sex. It is released in anticipation of pleasurable activities, including sex, thus driving the motivation to pursue it. Dopamine levels rise significantly when anticipating sex, which narrows our focus and increases our desire to act on this craving 1 2.

2. Arousal and Response: During arousal, dopamine increases and plays a role in the sexual pleasure pathway. However, there is a complex interplay with other neurotransmitters and hormones. For example, after orgasm, dopamine levels drop and prolactin levels increase, leading to a refractory period and a general state of calm, which may facilitate pair bonding 2 3.

3. Impacts of Drugs: Various substances that modulate dopamine levels can affect sexual response. For instance, drugs that increase dopamine, like certain antidepressants or recreational drugs, can result in a high desire but sometimes impede physical arousal or satisfaction 2.

4. Overall Increase: The act of pursuing and engaging in sex doubles the amount of dopamine in the bloodstream, marking a significant increase from baseline levels 4.

Maintaining a balance in dopamine levels is crucial for healthy sexual function and desire, with both high and low extremes potentially causing issues in sexual response.
