From Shame to Science: How Sexual Connection Regulates the Nervous System and Supports Mental Health

Oxytocin/Dopamine released through sex has many health benefits

What if I could give you one prescription that could cure, or drastically improve, any mental illness. What if I told you that you’d have a lot of fun doing it. You’d improve all the connections in your life, including your connection with yourself. What if I told you that there are no side effects and it’s non-pharmaceutical. Would you do it? What if I told you that the prescription was sex. 

Most of my patients balk at the idea. 

“Don’t let my husband hear you say that.” A crinkled nose. “Uuuugh, really?” 

Really. 

Dopamine has gotten a lot of press in the last few years, and undoubtedly, we have multiple medications that both lower and raise it. We’ve known about oxytocin for decades, but no one is talking about it. Oxytocin and Dopamine have several overlapping and interdependent effects. When I was in school, a professor said “the opposite of addiction is connection.” I have stuck to this wisdom in my practice as a provider, but as I read the new research, I see just how profound this revelation is.

Important brain remodeling happens for all people at puberty, parenthood, and again at menopause/andropause. Part of this remodeling process is directly mediated by oxytocin. The most studied area is directly post delivery, both mother and father experience drastic increases in oxytocin mediated neurons and consequently increases in dopaminergic activity in response to parental activities. (Wang et. al, 2014; Petersson & Uvnäs-Moberg, 2024) But the effects of oxytocin spread much farther than just parenthood. It is implicated in nearly every mental disorder that exists.

Eating disorders: 

• Oxytocin reduces food intake during meals, increases short term energy expenditure, and spontaneous physical activity. This effect is more pronounced in females during the estrogen mediated part of their cycle. (Liu et al 2021)

• Oxytocin preferentially reduces intake for sweet-tasting carbohydrate based food. (Klockars et al 2015)

• Oxytocin moderates food intake. It has been shown to both increase food intake in anoretic patients and decrease food intake in obese patients with compulsive eating. (Iovino et. al 2024)

PTSD:

• In response to acute stress, dopamine increases, but in response to chronic stress it decreases. Oxytocin mediates stress effects via decreasing cortisol levels and blood pressure. (Cardoso et al., 2013)

Depression

• Low levels of oxytocin have been implicated in depression in females, this was not held true for males in the same study. (Ozsoy et. al 2009)

ASD/ADHD

• There have been correlations noted between oxytocin receptor polymorphism and ASD. (Yrigollen et. al, 2008)

• Lower levels of oxytocin and dopamine have been associated with ADHD. Mice who were treated with oxytocin prior to methylphenidate administration had a much larger response to the medication. (Hersey et al. 2023) Lower levels of oxytocin were found in children with ADHD. (Levi-Shachar et al. 2020)

Schizophrenia

• Oxytocin has been associated with the negative symptoms of schizophrenia. (Rubin et al, 2010)

There are many ways to increase oxytocin including playing games, exercise, listening to music, eating food, socializing, touch, and massage.  But honestly, the easiest way to increase oxytocin quickly requires no money, and can be done in the privacy of your own bedroom. Orgasms. 

Due to shame from purity culture, patriarchal ideals around virginity, and body ideals women have become horrifically disconnected from their bodies. What should be pleasurable, second nature, and fun has become a chore. Men know they should want it but don’t know how to get it, and women (generally) find it repulsive. Women can orgasm in 28 different documented ways and can have multiple orgasms. Their bodies are primed to be attuned to oxytocin as their primary regulating hormone. Oxytocin reduces cortisol levels and stabilizes the nervous system. While oxytocin is regulating for males, it's doubly so for women. Yet, we are afraid to embrace our sexuality because of shame. And what a shame.

We spend billions of dollars each year searching for the next breakthrough molecule to fix what hurts in the human mind. Yet one of the most powerful regulators of our nervous system has been with us all along. Oxytocin is not fringe science or mystical thinking. It is a measurable, biologically active hormone that reshapes neural pathways, buffers stress, enhances dopamine signaling, and deepens connection. And connection, as we are learning again and again, is the antidote to so much suffering.

Sex is not a cure-all. It is not a replacement for therapy, medication, or comprehensive psychiatric care. But it is a biologically potent, evolutionarily designed regulator of the very systems we target with prescriptions. Orgasms, touch, attuned partnership, and embodied pleasure activate pathways that calm cortisol, stabilize mood, reinforce bonding, and even remodel the brain during key life transitions. We should not be embarrassed by that—we should be curious about it.

The tragedy is not that sexuality is powerful. The tragedy is that shame has severed so many people from one of their most accessible tools for regulation and connection. Particularly for women, whose physiology is exquisitely attuned to oxytocin, cultural narratives have transformed pleasure into performance, obligation, or disgust. When we disconnect from our bodies, we disconnect from one of our primary stabilizing systems.

If the opposite of addiction is connection, then perhaps the opposite of despair is embodied connection—to ourselves and to others. Demystifying sexuality is not about hedonism; it is about mental health. It is about reclaiming a built-in regulatory system that strengthens relationships, softens trauma responses, supports recovery, and reminds us that our bodies are not problems to manage but allies in healing.

We don’t need to wait for a prescription pad to access this medicine. We need education, safety, consent, and a cultural shift that allows pleasure to be seen as part of wellness rather than apart from it.

Connection is powerful. Our biology proves it.
