Testosterone, Dopamine and the Coolidge Effect
Once plighted, no men would go whoring.
They'd stay with the one they adore,
If women were half as alluring
After the act as before.
The Power of Equilibrium
- Oxytocin reduces cravings. When scientists administered it to rodents who were addicted to cocaine, morphine, or heroin, the rats opted for less drugs, or showed fewer symptoms of withdrawal. (Kovacs, 1998)
- Oxytocin calms. A single rat injected with oxytocin has a calming effect on a cage full of anxious rats. (Agren, 2002)
- This quality of oxytocin explains why companionship can increase longevity—even among those who are HIV positive (Young, 2004). Or speed recovery: wounded hamsters heal twice as fast when they are paired with a sibling, rather than left in isolation (DeVries, 2004).
- It may also explain why, among various species of primates, care-giving parents (whether male or female) live significantly longer. (Cal Tech, 1998)
- Oxytocin appears be a major reason that SSRI’s [Prozac-type drugs] ease depression, perhaps because high levels of cortisol are the chief culprits in depression and anxiety disorders. (Oxytocin counteracts cortisol's effects.) (Uvnas-Moberg, 1999)
- Oxytocin increases sexual receptivity and counteracts impotence, which may be one reason why this other way of making love remains pleasurable. (Pedersen, C.A., 2002), (Arletti, 1997)
