Low Libido
Desire is a brain state before it is a hormone level. We look at nervous system safety, hormone signaling, blood flow, toxic burden, and connection, without judgment.
What you may be noticing
Desire has faded. You love your partner, yet intimacy feels like another task. Perhaps arousal takes longer, or the interest is simply absent. You may feel guilty, worried, or disconnected from a part of yourself that used to feel natural.
Low desire that arrives with depression, relationship distress, or a history of trauma deserves gentle, skilled support from a qualified therapist alongside physiological care.
Why it is rarely one thing
Desire is not a single hormone. It is a brain state. The hypothalamus, the reward circuitry of the nucleus accumbens, the insula that reads signals from inside the body, and brainstem arousal centers must all register safety before the body opens to pleasure. When the brain perceives threat, whether from stress, pain, exhaustion, or old memories, access to pleasure narrows. The body does not prioritize reproduction when it perceives danger.
In my framework the brain is the master system. The cortex and limbic system inform the hypothalamus, which signals the pituitary, which instructs the ovaries, testes, thyroid, and adrenal glands. Your hormones are not failing. They are following instructions.
Many factors shape those instructions. Chronic stress and sympathetic dominance suppress sex hormone signaling. Thyroid underactivity lowers energy and drive. Perimenopause, the postpartum season, and hormonal contraception can lower testosterone and estrogen. In men, low testosterone, insulin resistance, and poor sleep are common. Arousal in every body depends on healthy blood vessel lining and nitric oxide. Endocrine-disrupting chemicals from plastics and fragrance add to what I call the toxic burden bucket. Some medications, low iron, and pain also play a role. Not a personal failing, but a signal from physiology and life.
Patterns we look for
- Autonomic balance and how quickly you shift out of stress.
- Sex hormones and their metabolites: testosterone, estradiol, progesterone, DHEA, and SHBG.
- Thyroid function and cortisol rhythm.
- Blood vessel health, insulin resistance, and nitric oxide signaling.
- Iron, vitamin D, and zinc status.
- Endocrine-disrupting exposures and toxic burden.
- Sleep quality and sleep apnea.
- Medications that affect desire.
- Pelvic pain or dryness that makes intimacy uncomfortable.
How I evaluate it
The comprehensive functional neurological exam assesses autonomic balance, pupil and heart rate responses, limbic reactivity, and sensory pathways, which together shape arousal.
Functional labs may include a full thyroid panel, a cortisol rhythm, prolactin, ferritin, vitamin D, zinc, fasting insulin, and HbA1c. For hormones, I prefer a profile that maps precursors, metabolites, and conversion pathways rather than a single number, because the pattern tells the story.
How we address it
- Identify medical contributors and review medications with your prescriber; never stop one on your own.
- Restore nervous system safety first with breathwork, vagal tone training, and limbic retraining.
- Open drainage pathways and lower the toxic burden bucket, including endocrine disruptors in your home and personal care.
- Restore sleep, circadian rhythm, thyroid, iron, and nutrient status.
- Support circulation and nitric oxide through movement, nitrate-rich vegetables, and insulin sensitivity.
- Address sex hormone patterns, coordinating any hormone therapy with your physician.
- Address pain or dryness, and support connection, with therapy when helpful.
Desire also differs between people and across seasons of life. For many, especially in long relationships, desire is responsive rather than spontaneous: it arises after closeness begins. Understanding this lifts a great deal of pressure. The goal is a sense of vitality and connection that feels right to you.
We approach this topic with discretion and respect. When the brain feels safe and the body is restored, desire often follows naturally.
