Low testosterone levels can significantly impact your partner's physical, emotional, and social health, negatively affecting your relationship. We'll explain how low testosterone affects mood, libido, and overall quality of life, and offer insights into how you can recognize these changes and support your partner.
Does he suddenly seem more reserved and less energetic? Is your partner no longer interested in doing things together like they used to? A testosterone deficiency could be the cause. Testosterone is a crucial hormone in a man's body that influences not only his physical performance but also his emotional and social health. It plays an important role in maintaining libido, mood, and overall energy levels ( Hintikka et al., 2009 ). When testosterone levels drop, this can have far-reaching consequences that not only affect individual well-being but can also fundamentally change the dynamics of relationships ( Roney & Gettler, 2015 ).
This article examines the impact of testosterone deficiency on interpersonal relationships, particularly romantic partnerships. It considers not only the obvious physical symptoms but also the more subtle emotional and psychological changes that can be triggered by low testosterone levels. We explore how fluctuations in this important hormone can affect emotional connections, communication patterns, and overall relationship quality ( Kornienko et al., 2016 ). This article aims to help you recognize changes in your partner's behavior and well-being and, by gaining a better understanding of the causes of these changes, find ways to support your partner and strengthen the relationship.
Testosterone deficiency: Widespread and often undetected
Testosterone deficiency in old age, also known as "age-related hypogonadism" or "functional hypogonadism," is far more common than often realized. Studies indicate that between 10 and 40% of all men suffer from this deficiency ( Mulligan et al., 2008 ). Far too often, however, it goes undetected and consequently untreated. From the age of 30, testosterone levels decline by an average of 1-2% per year, which is why the prevalence of this condition increases sharply with age ( Stanworth & Jones, 2008 ). But it's not only older men who are affected; symptoms can also occur before the age of 40.
This is by no means a "lifestyle problem," but a serious condition that absolutely requires medical evaluation. If a manifest testosterone deficiency is diagnosed, it can now be effectively treated with medically supervised testosterone replacement therapy – although initial effects typically appear after about four weeks, depending on the symptoms. This approach can significantly improve your partner's quality of life and, ultimately, your own ( Haider et al., 2024 ).
Recognizing the warning signs correctly
A testosterone deficiency can cause a variety of physical, psychological, and emotional symptoms. While there are typical signs of a deficiency, there are also less typical or specific symptoms that can indicate a testosterone deficiency. If you observe one or more of the following symptoms in your partner, a testosterone deficiency could be the cause. It is important to take these signs seriously and consult a doctor to obtain an accurate diagnosis and begin the best possible treatment.
Common (classic) symptoms of testosterone deficiency
- Decreased libido: A significant decrease in sexual desire is one of the most common and noticeable symptoms ( Hintikka et al., 2009 ).
- Erectile dysfunction: Difficulties getting or maintaining an erection are also widespread ( Wang et al., 2000 ).
- Fatigue: Men with low testosterone levels often feel exhausted and have little energy ( Wang et al., 2000 ).
- Muscle loss: A decrease in muscle mass and strength can occur because testosterone plays an important role in muscle building ( Bhasin et al., 1997 ).
- Weight gain: In particular, an increase in abdominal fat is frequently observed ( Wittert et al., 2003 ).
- Bone density loss: Low testosterone levels can lead to reduced bone density and an increased risk of osteoporosis ( Fink et al., 2006 ).
Lesser-known symptoms of testosterone deficiency
- Mood swings: Testosterone affects mood, and a deficiency can lead to irritability, anxiety, and depression ( Hintikka et al., 2009 ).
- Concentration problems: Men with low testosterone may have difficulty concentrating and thinking clearly ( Smith et al., 2018 ).
- Sleep problems: Insomnia or disturbed sleep are also possible symptoms ( Agrawal et al., 2022 ).
- Hot flashes: Similar to women during menopause, men can experience hot flashes ( Harvard Health, 2021 ).
- Reduced motivation: A general lack of drive and interest in activities that were previously enjoyable can occur ( Zitzmann, 2020 ).
- Hair loss: Although this can also be genetically determined, low testosterone levels can contribute to hair loss ( Jerjen et al., 2021 ).
What many don't know: Testosterone production in men doesn't automatically decline with age. Instead, the causes often lie elsewhere. In particular, common diseases such as type 2 diabetes ( Putta et al., 2017 ), obesity ( Kelly & Jones, 2015 ), high blood pressure, and lipid metabolism disorders contribute to reduced testosterone production in the body. These diseases often only manifest later in life, which explains why many older men are affected ( Tishova et al., 2024 ).

Furthermore, an unhealthy lifestyle has a significant impact on testosterone levels. An unbalanced diet ( Allen & Key, 2000 ) and insufficient physical activity ( Riachy et al., 2020 ) can negatively affect hormone balance and lead to a drop in testosterone levels. It is therefore important to pay attention to a healthy lifestyle to support testosterone production and promote overall health.
The role of testosterone in relationships
Testosterone is not only essential for men's physical health, but also plays a crucial role in their emotional and social relationships ( Roney & Gettler, 2015 ). A healthy testosterone level significantly contributes to men feeling energetic and motivated. This energy and motivation are important not only in everyday life, but also in their partnerships. Low testosterone levels can lead to fatigue and a lack of motivation, which can negatively impact a man's willingness to participate in shared activities and the quality of time spent together. Activities that previously brought him joy and connection may now seem indifferent or even burdensome ( Zitzmann, 2020 ).
If your partner has changed recently and no longer enjoys shared activities such as cycling, walking, meeting friends or going to restaurants, a low testosterone level could be the cause.
Emotional connections and mood swings
Low testosterone levels can lead to significant mood swings and even depression ( Hintikka et al., 2009 ). Men with testosterone deficiency often report a general feeling of exhaustion and irritability. This constant fatigue and irritability can severely impair a man's emotional balance, which in turn negatively affects his relationships ( Edelstein et al., 2014 ).
Mood swings can make men less patient and understanding, which can lead to increased conflict and misunderstandings in the relationship. A man who previously characterized himself as balanced and cheerful may suddenly appear irritable and unapproachable. These changes can be difficult for his partner to understand and can be stressful. If your partner suddenly seems emotionally distant or less interested in spending time with you, this can also be a sign of low testosterone.
These emotional changes negatively impact the quality of time spent together and weaken the emotional bond. The relationship can suffer if it is not understood that these changes may be due to a medical condition. It is important to take these signs seriously and work together to find solutions to strengthen the relationship and improve the well-being of both partners ( Tyborowska et al., 2023 ).
Communication and conflict
Testosterone also influences how men communicate and react to conflict. A deficiency of this hormone can cause men to be more reserved or even irritable in discussions. This can make communication in relationships more difficult and lead to misunderstandings ( Knight et al., 2022 ).
Physical symptoms and their impact on the relationship
The physical symptoms of low testosterone can significantly impact sex life and intimacy in a relationship. Among the most common physical symptoms are decreased libido and erectile dysfunction ( Hintikka et al., 2009 ). These problems can considerably affect your partner's self-confidence and well-being, leading to insecurity and frustration for both partners ( Dalton & Ghosal, 2018 ). A decreased libido can cause your partner to show less interest in sexual intimacy. This can create misunderstandings and insecurities in the relationship, as the other partner may feel rejected or less desired. Sexual connection is an essential component of many partnerships, and a decline in sexual interest can negatively affect feelings of closeness and connection.
Erectile dysfunction is another common symptom of testosterone deficiency. Men who have difficulty getting or maintaining an erection may feel disappointed and insecure ( Wang et al., 2000 ). These problems can lead to stress and anxiety, which further complicates sexual intimacy. The pressure to "perform" can exacerbate the situation, creating a vicious cycle of failure and frustration.
What you can do
If you suspect your partner is suffering from low testosterone, encourage them to see a doctor. A diagnosis and appropriate treatment can help alleviate symptoms and improve their quality of life. It's also important to be patient and supportive. Open communication and understanding can help strengthen the relationship despite the challenges.
Our conclusion, your knowledge
A healthy testosterone level is crucial for a man's emotional and physical health and has a significant impact on his relationships. Testosterone deficiency can lead to a variety of symptoms that can negatively affect both individual well-being and the dynamics of a partnership. From decreased libido and mood swings to physical exhaustion, the effects of low testosterone are diverse and often distressing.
By learning about the symptoms and effects of low testosterone, you can recognize early signs and offer your partner the necessary support. Open communication about these issues is crucial to avoid misunderstandings and find solutions together. Medical advice and possible treatments, such as testosterone replacement therapy, can significantly improve your partner's quality of life and, consequently, your own. Working together to overcome these challenges can even strengthen your relationship. You'll not only show your partner understanding and support, but you'll also actively contribute to improving their health and your relationship.
