Why Do I Have Low Libido?

It can be confusing and distressing when your sex drive seems to vanish without explanation. You may still love your partner and want to feel desire, but the spark just isn't there. If you're asking yourself "why do I have low libido?" the answer may lie in your hormones — and the solution may be simpler than you think.

Your Hormones Drive Your Desire

Sexual desire is not purely psychological — it is fundamentally biological. Testosterone is the primary hormone of desire in both men and women. It stimulates the brain's sexual interest centers, enhances physical sensitivity, and drives the motivation to seek intimacy. When testosterone declines — whether from aging, stress, medical conditions, or other causes — libido often declines with it.

Why Libido Declines with Age

For women, the hormonal shifts of perimenopause and menopause bring declining estrogen, progesterone, and testosterone. This triple decline affects not only desire but also physical arousal, lubrication, and comfort during intercourse. Many women assume their low libido is a natural and permanent part of aging, but it doesn't have to be.

For men, testosterone begins declining around age 30. By middle age, many men have testosterone levels well below what they experienced in their 20s and 30s. The decline is gradual enough that many men adapt to their reduced desire without recognizing that it's a treatable hormonal issue.

Other Hormonal Contributors

Elevated cortisol from chronic stress directly suppresses sex hormone production. Your body essentially deprioritizes reproduction when it perceives ongoing threat. Thyroid imbalances can drain the energy and motivation needed for sexual interest. Even insulin resistance and blood sugar instability can impair arousal and desire by affecting blood flow and nerve function.

The Medication Factor

Antidepressants, particularly SSRIs, are notorious for suppressing libido. Birth control pills can lower free testosterone levels. Blood pressure medications, antihistamines, and even some pain medications can dampen desire. If your libido decline coincided with starting a new medication, the connection may be direct.

Getting Your Desire Back

The first step is a comprehensive hormone evaluation to determine whether hormonal imbalances are contributing to your low libido. At The Riegel Center, Dr. Riegel assesses the full spectrum of hormones that influence desire — testosterone, estrogen, progesterone, thyroid, cortisol, and DHEA — and creates a personalized bioidentical hormone treatment plan to restore balance. Many patients experience a significant return of desire within weeks of starting therapy. Schedule a consultation to take the first step.
