Do testosterone levels actually influence sex drive?

While some studies suggest a nuanced relationship, clinical practice consistently shows that testosterone is a primary driver of libido for both men and women. At HeydayMD, we find that many patients with 'normal' total levels still suffer from low desire due to low free testosterone or high SHBG. Restoring hormones to optimal physiological ranges often results in a significant improvement in sexual interest and function. If you're experiencing a persistent lack of drive, it's worth looking beyond just the total T number to see if hormone optimization could help.
