Biochem/physiol Actions

Testosterone undecanoate is an orally available prodrug of testosterone that has a very long elimination half-life. It is an androgen and anabolic–androgenic steroid that acts as agonist of the androgen receptor (AR). Testosterone undecanoate is mainly used in the treatment of low testosterone levels in men. Also, it was approved for treatment of male hypogonadism.

Male hypogonadism is often treated by testosterone (T) replacement therapy such as oral administration of the ester prodrug, testosterone undecanoate (TU). However, the systemic exposure to T following oral TU is very low due to esterase-mediated metabolism, particularly in the
