Overview<\/span>

What Testosterone Undecanoate is<\/h2>

Testosterone undecanoate is a testosterone ester used as testosterone replacement therapy in men with confirmed hypogonadism. It is available in different formulations, such as long-acting injection and oral capsules; the formulation is to be confirmed with the partner pharmacy. Testosterone is a controlled drug in several markets.<\/p>

Suitability and dosing are decided by a prescriber on the basis of the approved product information.<\/p><\/section>\n

How it works<\/span>

Testosterone replacement, released slowly<\/em><\/h2>

Testosterone undecanoate is a long-chain ester of testosterone. The ester is released and converted to testosterone gradually, restoring levels in men whose own production is insufficient. How often it is given depends on the formulation.<\/p>
