Full answer

Low libido is one of the most common symptoms across both sexes and reflects an interplay of hormones, mood, sleep, relationships, medications, and physical health. Hormonal contributors include low total or free testosterone, low estradiol, elevated SHBG, hyperprolactinemia, and thyroid dysfunction. Common medication contributors include SSRIs, beta-blockers, and finasteride. Within oMeds review, the workup integrates a full hormone panel with symptom and medication context; treatment addresses upstream drivers rather than symptom suppression.

Is TRT safe?
Provider-reviewed testosterone optimization is considered safe for most men with confirmed low testosterone when prescribed and monitored against a baseline biomarker panel. Safety depends on candidacy, dosing, delivery modality, and a recalibration cadence — not on the molecule alone.
What is BHRT?
BHRT is provider-reviewed hormone optimization using bioidentical estrogen, progesterone, and (where indicated) testosterone — molecules structurally identical to those the body produces. It is calibrated against a baseline biomarker panel and read in the context of cycle phase, perimenopause, or menopause.
