1. A method of treating testosterone deficiency in a subject in need thereof, the method comprising:
a) performing a treatment regimen comprising orally administering to the subject 400 mg of testosterone undecanoate (TU) daily with a meal, wherein the TU is administered in a pharmaceutical composition comprising TU, a non-sterol solubilizing agent effective for solubilization of the TU, and a phytosterol or phytosterol ester;
b) establishing a first steady state serum concentration of testosterone;
c) following step (b), providing a first steady state Serum Value of testosterone in the subject that is measured from about 3 hours to about 6 hours after administration of the pharmaceutical composition; and
d) performing a first titration of the testosterone undecanoate, wherein:
i) if the first Serum Value of testosterone is less than about 460 ng/dl, then orally administering to the subject about 600 mg TU daily to establish a second steady state Serum Value of testosterone that is higher than the first steady state Serum Value of testosterone;
ii) if the first Serum Value of testosterone is from about 460 ng/dl to about 971 ng/dl, then continuing to orally administer to the subject about 400 mg TU daily to maintain the first steady state Serum Value of testosterone; or
iii) if the first Serum Value of testosterone is greater than about 971 ng/dl, then orally administering to the subject about 200 mg TU daily to establish a second steady state Serum Value of testosterone that is lower than the first steady state Serum Value of testosterone.
