Clear explanation

1. Why libido can decrease (common causes)

Low sexual desire is often multifactorial. Common causes include:

• Hormonal changes (low testosterone, menopause, thyroid disorders)
• Chronic illnesses (diabetes, cardiovascular disease)
• Mental health conditions (depression, anxiety)
• Stress, relationship issues, and fatigue
• Medication side effects (e.g., antidepressants, antihypertensives)

Before considering libido supplements, it is important to identify and address underlying causes. In many cases, treating the root problem improves sexual desire.

2. How low libido may manifest

Reduced libido can present as:

• Decreased interest in sexual activity
• Fewer sexual thoughts or fantasies
• Difficulty becoming aroused
• Relationship strain due to mismatched desire

When symptoms cause distress or interpersonal difficulty, medical assessment is recommended. You may also explore related topics in our Health Glossary for definitions of sexual health terms.

3. How doctors evaluate sexual desire concerns

Diagnosis is primarily clinical and may include:

• Detailed medical and sexual history
• Medication review (to identify possible contributors)
• Physical examination
• Laboratory tests (e.g., testosterone, thyroid function, glucose levels)

In some cases, referral to a gynecologist, urologist, endocrinologist, or mental health professional is appropriate. Educational medical events and webinars may also help patients better understand sexual health conditions.

4. Approaches: where libido supplements fit

Libido supplements are widely marketed as natural enhancers of sexual desire and performance. Common ingredients include ginseng, maca, Tribulus terrestris, L-arginine, zinc, and B vitamins.

What the evidence says:

• Some herbal ingredients (e.g., ginseng) show modest benefits in small studies, particularly for erectile function.
• L-arginine may support blood flow through nitric oxide pathways.
• Evidence for testosterone-boosting effects of over-the-counter herbs is limited and inconsistent.

However, supplements are not regulated as strictly as prescription medications in many countries. Product quality, dosage, and purity may vary. Libido supplements should not replace evidence-based treatments for diagnosed conditions.

When to see a doctor urgently

Key terms in simple words

Testosterone	A hormone linked to sex drive	Low levels may reduce libido

Specialist comment (generalized): “In clinical practice, reduced libido is rarely caused by a single factor. While some patients report subjective improvement with libido supplements, we emphasize identifying medical, psychological, and relational contributors first. Supplements may play a supportive role, but they should not replace a thorough evaluation.”
