Can Testosterone Help With Depression In Men And Women?

Depression is one of the most common mental health conditions in the United States, affecting millions of people each year. While standard treatments like therapy and antidepressant medications help many, some people continue to struggle with symptoms. This has led researchers and doctors to explore other factors that might influence mood, including hormones like testosterone. The evidence suggests that low testosterone is linked to a higher risk of depression, and for some people, testosterone therapy may help relieve depressive symptoms — but it is not a first-line treatment, and the results depend heavily on the individual.

What Is the Link Between Testosterone and Depression?

Testosterone is often thought of as a male sex hormone, but it plays important roles in both men and women. It affects muscle mass, bone density, energy levels, and sex drive. It also influences brain chemistry, including the areas that regulate mood.

Studies have found that people with depression tend to have lower testosterone levels than people without depression. This association appears stronger in men, particularly older men. As men age, testosterone levels naturally decline, and this drop may contribute to mood changes.

In women, the relationship is less clear. Women produce much smaller amounts of testosterone than men, but those levels still matter. Some research suggests that low testosterone in women may be linked to depression, fatigue, and reduced well-being, but the evidence is not as strong or consistent as it is in men.

It is important to understand that this link works in both directions. Low testosterone may contribute to depression, but depression itself can also lower testosterone levels. Stress, poor sleep, and certain medications used for depression can all suppress testosterone production. This makes it difficult to know which came first.

Can Testosterone Help With Depression In Men And Women?

Testosterone therapy can help with depression in some people, but it depends on whether they actually have low testosterone. For men with clinically low testosterone levels and depression, testosterone therapy has been shown in some studies to improve mood symptoms. For men with normal testosterone levels, there is little evidence that adding more testosterone will help with depression.

A major analysis of clinical trials published in JAMA Psychiatry found that testosterone treatment reduced depressive symptoms in men, particularly in those who had low testosterone levels at the start of treatment. The effect was most noticeable in men with moderate to severe depression.

For women, the evidence is much more limited. Some small studies have suggested that testosterone therapy may improve mood and well-being in women with low testosterone, but no large clinical trials have confirmed this. Because of this, testosterone is not commonly prescribed for depression in women.

It also matters how you define “help.” Testosterone therapy may improve energy, motivation, and sexual function. These improvements can indirectly lift mood, even if the therapy is not acting directly as an antidepressant. For someone who feels tired and uninterested in life because of low testosterone, restoring those levels can make a real difference.

How Does Testosterone Affect Mood and Brain Function?

Testosterone influences the brain in several ways that could affect mood. It binds to receptors in areas of the brain that regulate emotion, including the amygdala and the hippocampus. These regions are involved in processing stress and forming memories.

Testosterone also affects the activity of neurotransmitters — the chemical messengers in the brain. It influences serotonin, dopamine, and GABA, all of which play roles in mood regulation. Low testosterone may reduce the activity of these systems, which could contribute to depressive symptoms.

There is also evidence that testosterone reduces the activity of the hypothalamic-pituitary-adrenal (HPA) axis, which controls the body’s stress response. When this system is overactive, it can lead to high levels of cortisol, the stress hormone. Chronic high cortisol is associated with depression. By dampening this stress response, testosterone may help protect against some of the negative effects of chronic stress.

In men, low testosterone is also associated with physical changes that can affect mental health. Reduced muscle mass, increased body fat, low energy, and erectile dysfunction can all contribute to poor self-image and social withdrawal. Treating the physical symptoms can improve quality of life, which in turn can improve mood.

Who Should Get Testosterone Levels Checked?

Doctors do not recommend routine testosterone screening for everyone with depression. Testing is generally reserved for people who have symptoms of low testosterone along with their depressive symptoms.

Symptoms of low testosterone in men include:

• Low sex drive
• Erectile dysfunction
• Fatigue and low energy
• Loss of muscle mass
• Increased body fat
• Irritability or low mood

In women, symptoms may include low libido, fatigue, and a general sense of reduced well-being. However, these symptoms are also common in depression itself, which makes it hard to tell them apart.

Testing is most useful in men over 40 who have persistent depressive symptoms that have not responded well to standard treatment. It is also reasonable to check testosterone in men with depression who have physical symptoms like low sex drive and fatigue that seem out of proportion to their mood state.

Normal testosterone levels vary by age and by the laboratory performing the test. In general, total testosterone levels below 300 ng/dL in men are considered low, though some labs use slightly different cutoffs. Testing should be done in the morning, when testosterone levels are highest, and should be repeated to confirm a low result.

What Are the Risks of Testosterone Therapy?

Testosterone therapy is not a harmless supplement. It carries real risks, and it should only be used under medical supervision.

In men, potential side effects include:

• Worsening of sleep apnea
• Increased red blood cell count, which raises the risk of blood clots
• Acne and oily skin
• Reduced sperm production and infertility
• Enlarged prostate or worsening of urinary symptoms
• Increased risk of heart attack or stroke in some populations

The cardiovascular risk deserves special attention. Some studies have raised concerns that testosterone therapy may increase the risk of heart problems in older men with existing heart disease. Other studies have not found this risk. The evidence is mixed, which means doctors must weigh the potential benefits against the potential harms for each patient.

In women, testosterone therapy is less commonly prescribed and is not approved by the FDA for treating depression or low libido. When it is used, it is typically in low doses and for short periods. Side effects in women can include acne, hair growth on the face, deepening of the voice, and changes in cholesterol levels.

Testosterone therapy is also not recommended for people with certain conditions, including prostate cancer, breast cancer, or untreated severe heart failure. Anyone considering testosterone therapy should have a full medical evaluation first.

What Are the Alternatives to Testosterone Therapy for Depression?

Testosterone therapy should not replace standard depression treatment. For most people, the most effective approach combines therapy and medication.

Psychotherapy, particularly cognitive behavioral therapy (CBT), has strong evidence for treating depression. It helps people identify negative thought patterns and develop coping strategies. It is as effective as medication for mild to moderate depression and works well alongside medication for more severe cases.

Antidepressant medications, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are effective for many people. They typically take several weeks to work, and finding the right medication may require trying more than one.

Lifestyle changes also matter. Regular exercise has been shown to improve depressive symptoms in multiple studies. It may work by boosting endorphins, improving sleep, and increasing self-esteem. Getting enough sleep, maintaining social connections, and reducing alcohol intake can also support mental health.

For people with confirmed low testosterone and depression, testosterone therapy may be used alongside standard treatment. The goal is to address the hormone deficiency while still treating the depression directly. Some doctors describe this as a two-part approach: fixing what is broken biologically while also giving the person tools to manage their mood.
