Can Low Testosterone Cause Gender Dysphoria? Symptoms & Impact Explained

Key Takeaway

• Gender dysphoria and low testosterone are distinct conditions with different causes, though some psychological symptoms like mood changes may overlap.
• Gender-affirming hormone therapy effectively reduces psychological distress and improves well-being for transgender men by aligning physical appearance with identity.
• Neuroimaging research suggests gender identity has biological roots, with brain structures in transgender individuals often sharing characteristics with their identified gender.
• Proper diagnosis requires thorough medical and psychological evaluations beyond hormone testing to distinguish between identity-based distress and physiological deficiency.
• TRT Australia is a specialised telehealth clinic providing doctor-managed testosterone replacement therapy specifically for cisgender men with clinical deficiency.

What Is Gender Dysphoria and How Does It Differ From Hormone Imbalance?

Gender dysphoria is the psychological distress caused by a mismatch between an individual’s gender identity and their sex assigned at birth. Recognized by the APA in the DSM-5-TR, This intrinsic condition stems from an incongruence in identity rather than abnormal hormone levels. For transgender men, testosterone therapy is a gender-affirming treatment used to align physical characteristics with their authentic self, rather than a “cure” for a hormonal deficit.

In contrast, low testosterone (hypogonadism) is a physiological deficiency that typically develops later in life and does not alter a person’s core gender identity. While both conditions can cause overlapping symptoms like mood shifts and fatigue, they require distinct diagnostic paths. Clinical hormone imbalances involve restoring levels to a biological baseline. Gender dysphoria is managed through psychological support and gender-affirming care.

Testosterone’s Role in the Human Body

Understanding the relationship between testosterone and gender dysphoria requires examining how the hormone functions in the body, regardless of assigned sex.

Normal Testosterone Function in All Bodies

Testosterone plays key roles across all body types, including those assigned male at birth. This androgen hormone influences muscle mass development, bone density, fat distribution, red blood cell production, and sexual function.

In people assigned female at birth, testosterone is produced primarily in the ovaries and adrenal glands, albeit in smaller quantities than in those assigned male at birth where it’s primarily produced in the testes.

The hormone binds to androgen receptors (ARs) throughout the body, including brain tissue. These receptors are distributed across various regions and play roles in regulating mood, cognitive function, and even certain aspects of behaviour. 

Physical Effects of Low Testosterone

When testosterone levels drop below normal ranges for a person’s assigned sex, physical changes often follow. For those assigned male at birth, these may include decreased muscle mass, increased body fat (particularly in the abdominal region), reduced bone density, fatigue, diminished body hair, and sexual dysfunction.

These physical symptoms develop gradually and correspond to the degree of hormone deficiency. Importantly, they don’t include a change in gender identity or create a sensation of gender incongruence, which is the hallmark of gender dysphoria.

Psychological Effects of Hormone Fluctuations

The psychological impact of testosterone fluctuations can include mood changes, irritability, depression, difficulty concentrating, and decreased motivation. 

These effects occur because testosterone influences neurotransmitter function and neural pathways involved in mood regulation. Research has shown that restoring testosterone to normal levels can alleviate these psychological symptoms in individuals with a deficiency.

However, these mood and cognitive effects differ fundamentally from the experience of gender dysphoria. Low testosterone might make someone feel unwell or not like themselves due to mood disturbances, but it doesn’t create the persistent, deep-seated sense that one’s body doesn’t match one’s gender identity. This distinction guides proper diagnosis and treatment approaches.

Scientific Research on Testosterone and Gender Identity

Brain Structure and Gender Identity Studies

Neuroimaging research provides data on the relationship between brain structure, hormones, and gender identity. Studies examining the brains of transgender individuals have found that certain brain regions may more closely resemble the structures typical of their identified gender rather than their assigned sex at birth, even before hormone therapy. 

This suggests biological factors may contribute to gender identity development independent of current hormone levels.

Particularly notable is research on androgen and oestrogen receptors in the brain, which suggests genetic variations in how these receptors function may contribute to gender identity development. 

These biological factors help explain why simply having low or high testosterone doesn’t determine someone’s gender identity, as receptor function and sensitivity also play key roles.

Hormone Treatment Outcomes in Transgender Individuals

Studies examining the effects of gender-affirming hormone therapy consistently show significant improvements in psychological wellbeing for transgender individuals. 

Research published in Psychoneuroendocrinology has demonstrated that transgender men receiving testosterone report less social distress, anxiety, and depression compared to before treatment. These improvements occur despite the challenges many transgender individuals face regarding social acceptance and discrimination.

Brain imaging has revealed that testosterone treatment in transgender men affects regions where androgen receptors are expressed, creating patterns that more closely resemble cisgender male brains. Importantly, these changes don’t create the individual’s gender identity but rather align physical characteristics with their pre-existing identity, relieving the incongruence that causes dysphoria.

The molecular basis of gender dysphoria has been linked to interactions between androgen and oestrogen receptors, suggesting that how someone’s body processes sex hormones may contribute to gender identity development. 

This helps explain why transgender men experience relief from gender dysphoria with testosterone treatment—it allows their bodies to develop in ways congruent with their internal sense of gender, which appears to have biological foundations.

Why Correlation Doesn’t Equal Causation

A common error in discussions about hormones and gender identity is confusing correlation with causation. While testosterone affects physical characteristics and can influence mood, it doesn’t determine gender identity. If it did, then cisgender men with low testosterone would experience gender dysphoria and identify as women—which research consistently shows is not the case.

The relationship works in the opposite direction—gender identity leads transgender individuals to seek appropriate hormone therapy, rather than hormone levels causing gender identity. This explains why transgender men report that testosterone therapy feels “right” and alleviates dysphoria, while cisgender women would likely experience increased dysphoria if given the same treatment.

How Medical Professionals Approach Gender Dysphoria

Comprehensive Psychological Assessment

Before beginning any medical interventions for gender dysphoria, healthcare providers typically conduct thorough psychological assessments. These evaluations help confirm the diagnosis of gender dysphoria and identify any co-occurring mental health conditions that should be addressed simultaneously. 

This process typically includes multiple sessions with mental health professionals specialised in gender identity issues.

Unlike low testosterone diagnosis, which primarily relies on blood tests, gender dysphoria assessment focuses on the individual’s psychological experiences, history of gender incongruence, and the distress caused by this incongruence. 

The goal is to understand the person’s gender identity history and ensure that medical interventions are appropriate for their specific situation.

The Role of Endocrinology in Treatment

Endocrinologists play key roles in both the treatment of low testosterone and the management of gender-affirming hormone therapy. For low testosterone, endocrinologists focus on identifying the cause of hormone deficiency and restoring levels to normal ranges. 

For gender dysphoria in transgender men, endocrinologists administer testosterone to induce masculinisation that aligns with the individual’s gender identity.

The endocrinological approach differs significantly between these conditions. In low testosterone treatment, the goal is to restore hormone levels to what’s typical for the person’s assigned sex at birth. In gender-affirming care, the goal is to adjust hormone levels to match the person’s gender identity, which may mean achieving levels typical of a different sex than the one assigned at birth.

Regular monitoring of hormone levels, liver function, cholesterol levels, and other health markers is essential in both scenarios, though the target ranges and specific concerns vary based on whether the treatment is addressing hormone deficiency or providing gender-affirming care.

Why Simply Adding Testosterone Isn’t a “Cure”

A common misconception is that gender dysphoria could be “cured” by simply adjusting hormone levels. For cisgender individuals with low testosterone, hormone replacement restores physical and psychological function without changing gender identity. 

For transgender men, testosterone therapy helps align physical characteristics with an already-established male gender identity.

Gender identity has biological foundations beyond current hormone levels. These patterns help explain why transgender men experience relief from dysphoria with testosterone therapy, while cisgender women would likely experience increased distress from the same treatment.

Frequently Asked Questions (FAQs)

Can testosterone injections “cure” gender dysphoria in someone assigned female at birth?

Testosterone injections don’t “cure” gender dysphoria because gender dysphoria isn’t caused by hormone deficiency. Instead, for transgender men (individuals assigned female at birth who identify as male), testosterone therapy is part of gender-affirming care that helps align physical characteristics with their existing gender identity. 

Is low testosterone testing recommended before gender dysphoria diagnosis?

Low testosterone testing isn’t necessary or recommended as part of the diagnostic process for gender dysphoria. Gender dysphoria is diagnosed based on psychological criteria related to the persistent incongruence between gender identity and assigned sex, not on hormone levels. Hormone testing becomes relevant only after a gender dysphoria diagnosis, when planning for potential hormone therapy and establishing baseline health measures. 

How do doctors determine if symptoms are from low testosterone or gender dysphoria?

Distinguishing between symptoms of low testosterone and gender dysphoria involves considering the nature, history, and context of the individual’s experiences. Key diagnostic differences include the nature of the distress (focused on physical functioning versus gender identity), the timeline of symptom development (gradual onset in adulthood versus persistent from childhood), the relationship between symptoms and identity, and the individual’s response to the idea of different treatments. Medical professionals typically use a combination of psychological assessments, medical history, physical examination, and laboratory testing to differentiate between these conditions. 

Can hormone therapy help with both gender dysphoria and low testosterone?

For transgender men with testosterone levels that are low relative to typical male ranges, testosterone therapy serves dual purposes. It provides the masculinising effects that align with their gender identity while addressing symptoms related to hormone deficiency. 

The treatment approach is tailored to achieve testosterone levels in the typical male range, which alleviates both gender dysphoria and symptoms that would be considered low testosterone for someone living as male. For cisgender men with low testosterone, hormone replacement therapy addresses the physiological deficiency without affecting gender identity. The treatment targets restoration of normal male hormone levels to improve physical function, energy, mood, and other symptoms related to deficiency.

Does TRT Australia provide testosterone therapy for transgender men?

No, TRT Australia does not provide gender-affirming hormone therapy for transgender individuals. Our service specialises exclusively in treating cisgender men (men whose gender identity matches their male birth assignment) with diagnosed clinical testosterone deficiency. Gender-affirming hormone therapy for transgender individuals requires specialised expertise in transgender healthcare, including comprehensive psychological assessment, understanding of gender transition timelines, coordination with mental health professionals, and specific monitoring protocols that differ from treating hormone deficiency in cisgender men.
