a Mean level after 1 week of testosterone therapy.

b Baseline level for participants receiving T patch or T gel (50 mg/day). Average baseline level of serum testosterone for the pa rticipants receiving 100 mg/day T gel was 248 ng/dL.

NOTE: *Converted from nmol/L. The conversion factor from conventional units (ng/dL) to Système International (SI) units (nmol/L) is 0.0347. To convert ng/dL to nmol/L multiply by 0.0347 (JAMA, 2001).

BT = bioavailable testosterone; IM = intramuscular; T = testosterone; TE = testosterone enanthate; TC = testosterone cypionate; TT = total testosterone.
