A healthy sex life can help minimize depression and anxiety symptoms

When you struggle with anxiety or depression, sex may be the last thing on your mind. But understanding the physiological and mental benefits of a healthy sex life can help it become a tool for well-being.

  • The physiological responses our bodies have to sex can minimize the symptoms of anxiety and depression.
  • Deficiencies in nitric oxide are associated with irritability, depression, anxiety, insomnia, and less energy. Having sex increases your body's nitric oxide levels.
  • Sex also increases epinephrine, oxytocin, dopamine and serotonin, all of which are linked to mood, behavior, and well-being.


Depression can steal your sex drive and leave you feeling the deepest kind of lonely. And yet, sex can not only make you feel connected to another person, but the physical and biological responses our bodies have to sex can actually minimize some of the symptoms of depression.

And then there's anxiety. When you're suffering from anxiety, you feel cornered, lost and stuck; not able to take any steps forward. Sex is the last thing on your mind… and yet again—the physical and biological responses our bodies have to sex can minimize those symptoms, too.

Sex might not be a cure-all (wouldn't it be amazing if it was?) but there is a lot of evidence to prove that sex can have a positive impact on your state of mind, as well as your physical and mental health.

What happens in our bodies during sex

To explain this in more detail, let's talk about what biologically happens within our bodies when we are aroused and have sexual intercourse. This process begins before you have sex (and continues for a while after you have an orgasm), which is how having a healthy sex life can affect your moods, behaviors, and thoughts.

Arousal provokes activity in the “emotions” area of our brains

MRI studies have shown that the first thing to happen when we are aroused is that there is an increase in activity to the part of the brain that controls your emotions—this is called the limbic system.

During this initial arousal stage, a few physical things happen, as well: our blood pressure and blood flow increases, sensitive areas of our body (such as the genitals and breasts) become tender and our hearts beat faster. In general, arousal acts like an "on" switch for our bodies to prepare us for intercourse.

Sexual intercourse increases our nitric oxide activity, which impacts our anxiety and depression levels

When it comes to having intercourse, there are many complex things happening in our bodies and brains all at once. Along with the increased blood flow that happens when we're aroused, there is also a surge of nitric oxide released in our bodies while we have sex.

Nitric oxide molecules are essential in terms of our blood vessel health because these molecules relax the inner muscles of the blood vessels, which then causes those vessels to widen. This surge in nitric oxide explains why some areas of our bodies are tender during arousal and intercourse, and why our skin may become flushed when we are aroused.

It's important to note that some of the side effects of nitric oxide deficiency (which you can read more about here) are irritability, depression, anxiety, insomnia, and less energy.

People who struggle with nitric oxide deficiency often experience symptoms of anxiety and depression—and the reverse is also true: people who have an influx of nitric oxide (let's say, by having sex) can minimize their symptoms of depression and anxiety.

Sexual intercourse releases dopamine and serotonin, the “balancing chemicals” in our brains

An influx in nitric oxide isn't the only thing that happens in our bodies when we have sex.

Having sexual intercourse releases some other messages from our brain to our body, as well. These messages are called neurotransmitters.

Dopamine is one of those neurotransmitters, and it plays a huge role in how we feel pleasure. Not only that, but dopamine also plays a role in motivating our brains to feel that pleasure again.

When we have sex, our bodies spread the dopamine chemical along the various major pathways of our brains. This happens during many other pleasurable activities (not just sex), and like a car that's running smoothly until it isn't, you likely won't notice your body is doing this unless there is a problem with how your body carries out that function.

Dopamine deficiency can be linked to depression because our dopamine system is critical in transforming the perception of liking a reward into the motivation to seek out that reward.

Anyone who has struggled with this affliction can tell you that motivation and incentive are extremely difficult to find when you're experiencing depression.

Now, let's talk about serotonin because there is also an influx in serotonin when we have intercourse. Serotonin and dopamine affect many of the same things in our bodies, just in different ways. Both are equally important in regulating various bodily functions like sleep, emotions, and metabolism.

Researchers have been studying and analyzing the link between serotonin and depression for half a century now and while it was originally believed to be as simple as "low serotonin causes depression", the reality is far more complex.

In simple terms, low serotonin isn't a direct cause of clinical depression (as there isn't just one cause and they are extremely difficult to pinpoint due to our complex systems). However, raising your serotonin levels has proven to be one of the most effective depression treatments.

Why? Because serotonin is known to help regulate your mood, social behaviors, emotions, appetite and digestion, sleep, memory and sex drive. Some of the more prominent symptoms of anxiety and depression include erratic sleep, bad memory, hard-to-manage emotions and mood swings that alter your social behavior.

Taking this information into account, it makes total sense that regulating some of these body functions (by having regular sex and releasing these hormone-balancing chemicals) would help decrease the symptoms of these specific mental health concerns.

Sexual intercourse, epinephrine and the “feeling alive” sensation

We also have to talk about the epinephrine chemical that is released during sexual intercourse. Epinephrine is an adrenaline hormone. This hormone activates our sympathetic nervous system, which makes you feel that "heart pounding in your chest" kind of exhilaration you feel when you're out for a jog, getting a new tattoo or (you guessed it) having sex.

According to Medical News Today, low levels of epinephrine can often result in physical and mental symptoms such as feeling anxious or depressed.

The 2 big “O”s

The "O"s are "orgasm" and "oxytocin". Orgasms, you (hopefully) have when you have sexual intercourse. Oxytocin is the hormone that is released during orgasm.

Known as the 'love hormone', oxytocin is that "let's be together forever" feeling that plays a vital role in our pleasurable climaxes as well as how our body feels after we've reached climax. You get a big dose of oxytocin during an orgasm, but that's not the only time oxytocin makes an appearance. For women, oxytocin is also released during labor and while breastfeeding, which helps create that motherly bond between herself and her newborn baby.

See, oxytocin doesn't just make you feel good, and it's not just about feeling "in love"—but when our bodies experience surges in oxytocin we also begin to feel attachment and trust as a result of this hormone surge.

According to PET scans taken at the moment of orgasm, the reward circuits in our brains light up like fireworks and the center of reasoning and behavior temporarily shut down as you spiral into what can only be described as sexual bliss. You can see a really cool video by Rutgers University of said sexual fireworks shown in the female brain below.

Knowing what we know about anxiety disorders and how easily things are overthought to the point of bringing on a panic attack, that temporary shut off of reasoning can be incredibly helpful for someone who is feeling "stuck" in their own mind.

Given the link between orgasm and oxytocin (and the link between oxytocin and feeling good), it's not a far leap to consider the effect oxytocin released by sex can have on someone who is struggling with an anxiety or depression disorder.

Study suggests sperm donation, like organs, should be allowed post-mortem

Is it ethical to use a dead man's sperm to become pregnant?

  • Many parts of the world are suffering from a shortage of sperm donors due to the high bar for acceptance and varying laws regarding donor anonymity.
  • A recent article suggested that, as a solution, we should consider allowing men to opt-in to posthumous sperm donation, much like men and women do for organ donation.
  • It's technically feasible, but how would we navigate the complex ethical and legal issues surrounding such a proposal?

Can, and should, dead men procreate? Yes and yes, says a recent article published in the Journal of Medical Ethics.

The UK is facing a sperm donor crisis. According to the article, UK sperm banks only take on a few hundred new donors per year, forcing them to import thousands of sperm samples from the U.S. and Denmark, which dominate the global market for sperm donations due to their high supply.

These countries have a high supply of sperm primarily because of laws and regulations protecting the donor's anonymity — in the UK, for instance, babies born from sperm donations are permitted to contact their biological father after they turn 18, an emotional confrontation that dissuades many from donating. In fact, in a 2016 study based in the U.S., 29 percent of current donors said they would have refused to donate if they could not be anonymous.

How can we increase the supply of sperm donors while simultaneously shielding donors from a potentially life-upending confrontation and providing children with the right to know their own ancestry? Allow for post-mortem sperm donations. Men could opt-in to become sperm donors after their death, just like they do as organ donors. So long as they were collected no longer than 48 hours after death, sperm could be collected via surgery or electrical stimulation of the prostate and be frozen for later use.

"If it is morally acceptable that individuals can donate their tissues to relieve the suffering of others in 'life-enhancing transplants' for diseases," wrote the article authors, "we see no reason this cannot be extended to other forms of suffering like infertility."

A legal and ethical quandary?

As it turns out, this idea isn't all that new. The first posthumous sperm retrieval occurred in 1980 after a 30-year-old man suffered a fatal brain injury in a car accident. His family requested that his sperm be preserved, which was done through surgery soon after he had been declared dead.

There have been numerous postmortem sperm retrievals since then, but they've always existed in a legal grey area. For instance, in 1997, a UK man named Stephen Blood caught meningitis, collapsed into a coma, and died soon after. His wife, Diane Blood, had requested that doctors extract two samples of semen from Mr. Blood.

However, the UK's Human Fertilisation and Embryology Authority had forbidden Mrs. Blood from using those samples to become pregnant, as Mr. Blood had passed away prior to giving written consent to the procedure. In the UK posthumous sperm donation is illegal without written consent. After an appeal, Mrs. Blood was permitted to seek fertility treatment outside of the UK and later gave birth to a son.

Other countries, such as France, Germany, and Taiwan, have a full ban on posthumous fertilization. At the same time, countries like the U.S. and Belgium have no legislation on the subject whatsoever. Given the complex legal, ethical, and medical nature of posthumous fertilization, this range of legislative response is not unexpected. For example, is it ethical to collect sperm from an individual who never wanted to procreate in a country where the young population is dwindling and sperm donors are in short supply? Such is the case in many parts of the UK Is it reasonable to collect sperm from donors who have died and who are, by extension, more likely to be older and with less healthy sperm? Is the offspring of a deceased sperm donor considered to be the donor's legal heir?

These and other issues muddy the waters for countries when crafting policies around posthumous sperm donation. However, the authors of the recent Journal of Medical Ethics article argue that allowing for this procedure is at the very least ethically permissible and likely beneficial for society at large.

"The ability to reproduce matters to people and donated sperm enables many people to fulfill their reproductive desires," write the authors. "It is both feasible and morally permissible for men to volunteer their sperm to be donated to strangers after death in order to ensure sufficient quantities of sperm with desired qualities."
