Low testosterone: Effects on fertility and potential solutions
September 16, 2025What Is Male Libido
Male libido, also known as sexual desire, is a key component of sexual health and overall well-being. It influences not only sexual activity but also mood, relationships, and self-confidence. The intensity of libido varies among men and changes with age, hormones, health, and lifestyle. When it remains low for a long time, it may indicate an underlying issue that needs to be addressed. Monitoring sexual desire is important, as it often serves as a “mirror” of overall health.
Factors Affecting Male Libido
- Hormonal changes:
Testosterone
is the primary hormone that determines sexual desire. When levels drop, libido decreases, erectile issues may occur, and energy levels decline. - Age: After the age of 40–50, testosterone production naturally decreases, which is why many men notice a gradual reduction in sexual desire. However, age alone is not a decisive factor; lifestyle and health care also play an important role.
- Psychological factors: Stress, depression, work pressure, and relationship difficulties are among the most common causes of reduced libido. Psychological well-being can directly affect sexual desire even in men with normal testosterone levels.
- Physical health: Chronic diseases such as
diabetes,
hypertension, heart disease, and obesity negatively affect sexual life. These conditions impair blood flow to the genital area, leading to reduced sexual function. - Medication: Many medications for depression, hypertension, or other chronic illnesses have side effects that lower sexual desire. In such cases, the treating physician may adjust the medication.
- Daily habits: Lack of sleep, excessive alcohol consumption, smoking, or drug use contribute to a gradual decline in libido and overall health.
Natural Ways to Boost Male Libido
- Balanced diet: Foods rich in zinc, magnesium, and B vitamins enhance testosterone production. Oysters, nuts, eggs, spinach, and fatty fish should be part of the diet.
- Physical exercise: Regular exercise improves blood circulation, boosts testosterone levels, and increases confidence. Weight training and aerobic activity, in particular, have proven benefits.
- Quality sleep: Good sleep (7–8 hours per night) is essential for hormone regulation. Sleep deprivation lowers testosterone and, consequently, sexual desire.
- Stress management: Techniques such as yoga, meditation, or deep breathing help reduce cortisol — the stress hormone that suppresses libido
- Healthy lifestyle: Avoiding smoking and excessive alcohol, along with maintaining a healthy weight, contributes to better erectile function and increased desire.
- Relationship and communication: Open communication with one’s partner reduces anxiety and strengthens emotional intimacy, which is vital for a healthy sexual life.
Medical Solutions for Low Libido
When low male libido is related to physical or hormonal causes, medical intervention is necessary.
- Testosterone Replacement Therapy (TRT): Recommended for men with low testosterone. TRT restores normal levels, improves libido, enhances erectile function, and increases energy.
- Medication: Drugs for erectile dysfunction or other treatments may be prescribed to improve sexual performance.
- Psychotherapy: Useful when psychological factors are involved. Support from a professional helps manage stress or depression.
- Holistic approach: Combining lifestyle changes with medical treatments yields the best and most sustainable results.
