Testosterone is a sex hormone produced primarily in the testicles and, in small amounts, in the ovaries. Its production peaks in early adulthood and then decreases yearly by up to 1%. Its deficiency can cause health issues, such as reduced muscle mass, weight gain, fatigue, depression, and sleep issues. Low sex drive also results from low testosterone, especially in men.
Medical providers prescribe testosterone replacement therapy (TRT) for some patients with low libido or recommend vitamins that boost testosterone production. This article explains when testosterone can help increase sex drive.

Does Testosterone Increase Sex Drive in Men?
Research shows testosterone therapy can help increase sex drive in men, but scientists still don’t know how exactly. One of the reasons for the uncertainty is the difficulty of determining what a normal sex drive is. What seems like a decreased libido in some men may be standard for others.
In addition, many factors contribute to reduced sexual desire and function, including other health issues, medications, stress, and lifestyle habits. If a medical provider establishes low testosterone levels after a physical examination and lab tests, they may prescribe testosterone replacement therapy for patients troubled by decreased sex drive.
Higher testosterone levels may enhance libido in men in several ways, directly or indirectly.
- By increasing sexual desire.
- By improving mood, which leads to an increased interest in sexual activities.
- By increasing muscle mass and reducing fat, which improves stamina and helps the patient feel more energetic.
- By helping with mild erectile dysfunction and enhancing sexual performance.

Testosterone therapy is FDA-approved for men with diagnosed low testosterone production (hypogonadism).
Does Testosterone Increase Sex Drive in Women?
In some cases, women experience a reduced interest in sexual activities because of low testosterone levels. However, the medical provider needs to determine whether low testosterone is the primary cause of the patient’s low sex drive. Fluctuations in estrogen levels, medication side effects, stress, and emotional problems more commonly contribute to this issue in women.
Note: This article explains the most common causes of low sex drive in women.
Testosterone therapy is an off-label treatment for women because there is little research data on its long-term safety and effectiveness. Patient experience shows it may help with libido in:
- Women who have a reduced sex drive due to surgically induced menopause.
- Postmenopausal women who take estrogen therapy but still experience decreased libido.
The Takeaway
The effectiveness of total testosterone therapy for the treatment of low sex drive depends on the cause of the patient’s low sex drive, the dose, and the preparation form (e.g., pill, gel, cream). It is essential to discuss the potential risks of using testosterone with your healthcare provider to determine if it is the right approach to improve your condition.
Conclusion
Testosterone deficiency is often linked to low sex drive in men and sometimes women. Medical professionals usually prescribe testosterone therapy to patients with clinically low testosterone levels. Many of them report a boost in their sex drive and the improvement of other related symptoms.
