Testosterone Undecanoate is the undecanoate ester form of the androgen testosterone, with gonadotropin-secretory inhibiting and hormone replacement activity. As testosterone inhibits the secretion of gonadotropins from the pituitary gland, administration of testosterone decreases the secretion of luteinizing hormone (LH). By inhibiting LH secretion, the growth of Leydig cells, which are normally stimulated by LH to produce testosterone, may be suppressed. In addition, this agent promotes the maintenance of male sex characteristics and can be used for testosterone replacement in hypogonadal males.

The testosterone undecanoate group has a higher percentage of men with newly diagnosed erectile dysfunction and obesity at follow-up, whereas the testosterone cypionate group had a higher percentage of men with diagnosed hypertension, congestive heart failure and chronic pain.
testosterone undecanoate half life
Testosterone undecanoate has a very long elimination half-life and mean residence time when given as a depot intramuscular injection. Its elimination half-life is 20.9 days and its mean residence time is 34.9 days in tea seed oil, while its elimination half-life is 33.9 days and its mean residence time is 36.0 days in castor oil.These values are substantially longer than those of testosterone enanthate (which, in castor oil, has values of 4.5 days and 8.5 days, respectively). Testosterone undecanoate is administered via intramuscular injection once every three months or so.
