Testosterone Undecanoate

What condition does Testosterone Undecanoate treat?

Testosterone Undecanoate is used in men who do not make enough of a natural substance called testosterone. In males, testosterone is responsible for many normal functions like the growth and development of the bones, genitals, and muscles. It also helps cause normal sexual development in boys or called puberty.

Testosterone Undecanoate is a long-acting man-made version of testosterone. This comes as a gelatin capsule for oral use. The Food and Drug Administration (FDA) has already approved this medication.
