Does hypothyroidism cause loss of libido?

Low thyroid hormone can affect energy, mood, sleep, and physical comfort. Those changes may reduce interest in sexual activity or make intimacy feel more difficult. Some people also notice vaginal dryness, erectile difficulties, or changes in menstrual cycles, depending on their body and other health factors.

A change in libido is personal and may be gradual. It does not point to one diagnosis on its own. Stress, depression, relationship difficulties, pregnancy or menopause, other hormone changes, chronic illness, and some medicines can contribute. A private, non-judgmental clinical conversation can separate these possibilities.

Book a routine appointment if reduced desire is persistent, distressing, or accompanied by tiredness, feeling cold, constipation, dry skin, or mood changes. Note when the change began and whether it followed a new medicine, illness, major stress, or a change in your menstrual cycle. Take prescribed thyroid treatment as directed and do not alter it or use libido supplements without advice. A clinician may review medicines and arrange thyroid or other appropriate tests.

Seek prompt help if low mood comes with thoughts of self-harm, inability to stay safe, or severe confusion. Urgent review is also needed for sudden severe pelvic or testicular pain, unexpected heavy bleeding, or a severe allergic reaction after a medicine. These problems need assessment independently of thyroid symptoms.

Could my thyroid function or current treatment be affecting my libido? Could any of my medicines contribute? Are dryness, pain, erection changes, or cycle changes relevant to the assessment? What support is available if stress, mood, or relationship factors are involved?
