Libido is the most sensitive hormonal canary in the coal mine. It usually drops months before fatigue, brain fog, or weight gain show up. The mistake is treating it as a relationship problem when it's a measurable lab pattern.
Total T under 400-500 ng/dL with low free T predicts low libido reliably. Often co-occurs with morning erection loss.
Estradiol drops in perimenopause crush libido. So does declining ovarian and adrenal androgen production. Both fixable.
Even with “normal” total testosterone, high SHBG (often from oral contraceptives, hyperthyroidism, or low insulin) leaves nothing free.
Often missed. A prolactin above ~20 ng/mL in men or above ~25 in women suppresses gonadal axis and crushes libido.
SSRIs, finasteride, beta-blockers, statins, and high-dose opioids all suppress libido. Worth flagging to your provider.
Bioidentical testosterone restores libido reliably when low T is the cause. Most men feel a shift within 3-6 weeks.
