1 .- 24 . (canceled)
25 . A method of treating chronic testosterone deficiency in a subject in need thereof comprising the steps of:
a. administering daily to a subject in need thereof an oral pharmaceutical composition comprising about 475 mg of testosterone undecanoate solubilized in a carrier comprising oleic acid, polyoxyethyelene (40) hydrogenated castor oil, borage seed oil, and peppermint oil:
b. measuring the serum testosterone concentration in the subject three to five hours following the daily administration of the oral pharmaceutical composition; and
c. increasing the dose of testosterone ester administered in step a. when the measured serum testosterone concentration in the subject is less than about 250 ng/dL, decreasing each dose of testosterone ester administered in step a. when the measured serum testosterone concentration in the subject is greater than about 700 ng/dL, and maintaining each dose of testosterone ester administered in step a. when the measured serum testosterone concentration in the subject is between about 250 ng/dL and about 700 ng/dL;
wherein steps a.-c. are repeated until the serum testosterone concentration in the subject is between about 250 and about 700 ng/dL; and
wherein the serum testosterone concentration is measured after seven days of daily treatment with the oral pharmaceutical composition.
26 . The method of claim 25 , wherein the oral pharmaceutical composition is administered twice daily.
27 . The method of claim 25 , wherein, once steady-state is achieved, the serum testosterone response does not decline over time.
28 . The method of claim 25 , wherein said oral pharmaceutical composition comprises:
a) 15-20 percent by weight of solubilized testosterone undecanoate;
b) 5-20 percent by weight hydrogenated castor oil ethoxylate;
c) 30-70 percent by weight of oleic acid; and
d) 10-15 percent by weight of digestible oil.
29 . The method of claim 25 , wherein said oral pharmaceutical composition is administered in one or more capsules.
