1. A method for maintaining a therapeutically effective concentration of testosterone in the blood serum of a male for treating hypogonadism which comprises
transdermally delivering to the male by applying to the skin a composition which is in the form of a topical gel, which has a viscosity of about 2000 to about 6000 cps and a pH of about 4 to about 8, and comprises: (A) about 0.1 to about 5 wt. % of
testosterone; (B) about 0.5 to about 25 wt. % of a macrocyclic enhancer selected from the group consisting of 3-methylcyclopentadecanone, 9-cycloheptadecen-1-one, cyclohexadecanone, cyclopentadecanone, oxacyclohexadecan-2-one and mixtures thereof (C)
about 1 to about 6 wt. % of a thickening agent; (D) a mixture of solvents which include: (i) about 60 to about 75 wt. % of ethanol or isopropanol; and (ii) propylene glycol and glycerin as co-solvents.
2. The method of claim 1 further comprising about 0.001 to about 5 wt. % of polyethylene glycol as a crystallization inhibitor.
3. The method of claim 1 wherein said composition is maintained on said skin for a period of time sufficient for delivery of the testosterone to the body of the male and is applied to the skin in the form of a unit dose which contains about 1 to about 300 mg of testosterone and such that, following a single application of the unit dose to the skin, the amount of circulating testosterone (AUC.sub.0-24) in the blood serum of the male achieved in the 24-hour period following the application is about 100 to about 35,000 ngh/dL greater than the amount of circulating testosterone (AUC.sub.0-24) in the blood serum of the male than would have been achieved in the same 24-hour period had the dose not been administered.
4. The method of claim 1 wherein the macrocyclic enhancer is 3-methylcyclopentadecanone.
5. The method of claim 1 wherein the macrocyclic enhancer is 9-cycloheptadecen-1-one.
6. The method of claim 1 wherein the macrocyclic enhancer is cyclohexadecanone.
7. The method of claim 1 wherein the macrocyclic enhancer is cyclopentadecanone.
8. The method of claim 1 wherein the macrocyclic enhancer is oxacyclohexadecan-2-one.
