Low Libido in Men and Women: A Functional Medicine Perspective

July 31, 2026; By Benjamin Kosubevsky

In the private, high-net-worth communities of Gulf Stream and Manalapan, conversations about sexual desire happen behind closed doors—if they happen at all. Low libido is one of the most common wellness concerns that patients bring to integrative medicine, yet it remains one of the most under-discussed topics in conventional healthcare. Whether you are a man experiencing a gradual decline in sexual interest or a woman whose desire has quietly disappeared during the perimenopausal years, the experience is the same: something fundamental feels missing, and nobody seems to take it seriously.

At The Longevity Center FL in West Palm Beach, our practitioners treat low libido as a clinical concern that deserves thorough investigation—not a lifestyle complaint to be brushed aside.

Libido Is Not Just Psychological

While psychological factors undeniably influence sexual desire—stress, relationship dynamics, body image, depression—the biology of libido is equally important and frequently overlooked. Sexual desire is mediated by a complex interplay of hormonal, neurological, vascular, and metabolic systems. When any of these are disrupted, desire declines—regardless of the quality of your relationship or your psychological state.

What Drives Libido Decline in Men

In men, the most commonly evaluated contributor to low libido is testosterone. Serum testosterone levels decline by approximately 1–2% per year after age 30, and this gradual decline can be associated with reduced sexual desire, erectile changes, fatigue, and mood shifts (Harman et al., Journal of Clinical Endocrinology & Metabolism, 2001). However, testosterone is not the whole story. Our practitioners also evaluate:

• Estradiol: Excess aromatization of testosterone to estradiol—often driven by increased body fat—can blunt libido even when total testosterone appears adequate
• SHBG (sex hormone-binding globulin): Elevated SHBG reduces the amount of free, biologically active testosterone available to tissues. A man with a “normal” total testosterone but high SHBG may effectively be functionally low
• Thyroid function: Both hypothyroidism and hyperthyroidism can affect sexual desire and function
• Insulin resistance and metabolic health: Metabolic dysfunction is independently associated with reduced testosterone and sexual dysfunction
• Medications: SSRIs, finasteride, opioids, and certain blood pressure medications are well-documented causes of libido suppression
• Sleep and stress: Chronic sleep deprivation and elevated cortisol can suppress the hypothalamic-pituitary-gonadal axis, reducing both testosterone production and sexual desire

What Drives Libido Decline in Women

In women, the hormonal landscape of desire is more nuanced. Estrogen, progesterone, testosterone, and DHEA all play roles in sexual motivation, arousal, genital blood flow, and lubrication. The menopausal transition—during which all of these hormones shift—is the most common inflection point for female libido decline, but it is not the only one.

A comprehensive position statement from the International Society for the Study of Women’s Sexual Health (ISSWSH) emphasized the importance of a biopsychosocial approach to female sexual dysfunction, noting that effective management requires addressing hormonal, relational, psychological, and contextual factors simultaneously (Parish et al., Journal of Sexual Medicine, 2021). Our practitioners apply this framework in practice.

Factors evaluated in women include:

• Estradiol, progesterone, testosterone, and DHEA-S levels across the menstrual cycle (when applicable) or in the postmenopausal context
• Thyroid function and adrenal status
• Vaginal atrophy and genitourinary symptoms of menopause (GSM), which can make intercourse painful and secondarily reduce desire
• Medication effects (particularly SSRIs and hormonal contraceptives)
• Sleep, stress, and relationship context

Options at The Longevity Center FL

How low libido is approached is entirely individualized based on what the evaluation reveals. Depending on the contributing factors identified, our practitioners may recommend:

• Hormone optimization: Testosterone replacement (at physiological doses appropriate for each sex), estrogen/progesterone therapy for women, thyroid optimization, or adrenal support
• PRP therapy: For women, PRP injection to genital tissue may support neovascularization and tissue regeneration. For men, penile PRP may support vascular and nerve tissue health. Both are offered under physician supervision with transparent discussion of the evidence base
• Peptide therapy: Certain peptides have been studied for their potential effects on sexual function through hormonal and neurological pathways
• Medication review: Identifying and—where medically appropriate—adjusting medications that may be contributing to libido suppression
• Lifestyle and nutritional support: Addressing sleep, stress management, exercise, and nutritional factors that influence hormonal health and sexual function

A review published in the New England Journal of Medicine described the clinical evaluation and management of female sexual dysfunction, noting that a multidisciplinary approach addressing both biological and psychosocial factors produces the best outcomes (Shifren, NEJM, 2020). The same principle applies to male sexual health.

Why This Matters

Low libido is not a vanity concern. Sexual desire and intimacy are fundamental components of quality of life, relationship health, and psychological wellbeing. They are also markers of underlying physiological health—hormonal balance, vascular function, nervous system regulation, and metabolic fitness. When libido declines, it is often a signal that something in the body’s broader system has shifted. Addressing it comprehensively benefits not just sexual function but overall health.
