Citat:Sex drive for the most part is modulated by dopamine, DHT, and estrogens. I said mostly because if your adrenals are fatigued or you're hypothyroid that can also contribute to loss of function.

It's possible your friend may have higher bioavailable testosterone but less favourable values for dopamine, DHT, and/or estrogens

Citat:[quote]As someone in similar shoes, i had sex every day with t levels around 210-240. Only time there was an issue was if my BP got too high. Increasing my t only made it better.[quote]

Citat:Half of the men with low testosterone have no symptoms at all, that does not change the fact that low-t can cause diabetes, or cardio vascular disease.
