The loss of libido in men is linked to physical or emotional causes and may affect sexual life. Healthy lifestyle habits may be considered by the doctor as part of an individualized approach to sexual well-being.
The word libido comes from Latin and means “desire”. However, it is not uncommon that, at certain moments in life, this desire is low and compromises sexual activity.
There are several causes of loss of male libido, which may be physical and emotional. Identifying them with medical guidance may assist in defining possible approaches related to sexual well-being.
Understand possible factors related to reduced sexual desire and learn information about approaches discussed in the medical literature.
What is low libido?
The libido is the biological and psychological impulse associated with sexual desire, regulated by hormones such as testosterone and by the action of brain neurotransmitters such as dopamine and serotonin.
Low libido is nothing more than the reduction of this desire. It may affect sexual behavior of men and women at different moments of their lives.
In young individuals, the loss of libido in men is usually temporary. However, around 30–40 years of age, the decline is more complex, since total testosterone begins to drop 1% per year and this decline directly affects sexual desire, according to a study published in the Reviews in Endocrine and Metabolic Disorders in 2022.
In addition, over time, the difficulty in obtaining or maintaining an erection may lead to reduced sexual interest, while low libido may favor erectile dysfunction.
Symptoms
Some signs may justify medical evaluation, especially when there is interference in the quality of sexual life:
- Persistent decrease in sexual desire, even in the presence of stimuli;
- Fatigue and reduced performance;
- Associated erectile dysfunction;
- Irritability, insomnia, lack of motivation.
Although symptoms may go unnoticed and be mistaken as normal, persistence suggests that hormonal, emotional, or physical balance may be affected.
Causes of loss of male libido
Emotional and psychological factors may be the most common causes in young individuals, while physical health issues and male hormonal problems tend to be more frequent after the age of 40.
- Low testosterone: the hormone is one of the factors responsible for regulating male sexual desire. When its level decreases, there is reduced sensitivity to stimuli and reduced sexual interest.
- Depression, stress, and anxiety: in addition to reducing concentration and emotional response to sexual stimuli, stress and anxiety increase cortisol levels. In excess, this hormone interferes with testosterone production and with the balance of neurotransmitters linked to pleasure.
- Use of medications: antidepressants (mainly SSRI type) alter the brain chemical balance and, consequently, the neurotransmitters responsible for excitement and sexual response.
- Diabetes, obesity, hypertension, and sleep apnea: these chronic conditions affect blood circulation, hormonal production, and nerve function, harming sexual response and testosterone production.
- Advancing age: after the age of 40, testosterone production tends to decrease naturally. Low testosterone in men contributes to loss of libido at this age group.
- Relationship problems and monotonous sexual routine: reduced connection and lack of interest between the couple may gradually decrease desire and libido.
Diagnosis
The diagnosis of loss of libido in men must be performed by a doctor, since it combines a clinical, hormonal, and psychological evaluation.
During the consultation, it is very important to understand, besides the patient’s health conditions, their sexual history and mental health — which includes levels of stress, anxiety, presence of marital conflicts, sleep quality and physical activity practice.
Some laboratory tests are also useful to identify the condition, such as:
- Total and free testosterone;
- Luteinizing hormone (LH);
- Follicle-stimulating hormone (FSH);
- Prolactin;
- Other tests to investigate metabolic disorders.
Treatments for loss of libido in men
Clinical management may vary according to the causes identified in medical evaluation. Therefore, diagnosis is very important.
Testosterone replacement therapy (TRT) is the most remembered treatment. However, it is only indicated for men with proven low testosterone levels, since hormonal spikes must be avoided.
TRT may be done via intramuscular injections, transdermal gels, patches, or subcutaneous implants. The goal is to restore testosterone to levels close to natural.
How to naturally increase male libido?
Lifestyle changes and emotional balance may help men recover libido and are part of the treatment.
Regular physical exercise, with professional guidance, may be associated with general health benefits, including aspects related to sexual well-being. Training must not be too intense or performed without adequate rest, since this leads to chronic cortisol elevation and ends up having the opposite effect on male hormones.
In addition, maintaining a balanced diet and controlling body weight favor hormonal metabolism. The diet must contain essential nutrients for hormonal production, blood circulation, and metabolic balance such as zinc, selenium, antioxidants, and vitamins A, C, and E.
Sleeping well is another essential factor. The relationship between sleep and testosterone occurs because most hormone production takes place during deep sleep.
To maintain mental health and libido, men may adopt relaxation techniques and seek psychological support, including a sex therapist. These strategies may be considered as part of a global approach, always with professional follow-up.
If necessary, during treatment to recover libido, the doctor may prescribe medications for erectile dysfunction. The doctor may evaluate, when appropriate, complementary measures during follow-up.
