What is claimed is: 1. A method of providing androgen therapy to a human subject, said method comprising: administering to the subject a modulator of testosterone bioavailability, wherein the modulator is a compound having the formula: wherein R1 is hydrogen or lower alkyl, and R2 is optionally substituted alkyl or optionally substituted phenyl wherein the phenyl has 0, 1, 2, or 3 substituents selected from the group consisting of lower alkyl, halogen, and trifluoromethyl, and R3, R4, R5, and R6 are independently selected from the group consisting of hydrogen and optionally substituted lower alkyl, and the bond between adjacent carbon atom a and carbon atom b can optionally be replaced by a single bond in which the adjacent carbons are independently substituted with hydrogen or methyl, and the pharmaceutically acceptable salts thereof; and orally administering in an oil vehicle-an androgen selected from the group consisting of testosterone, testosterone esters, and testosterone precursors. 2. The method of claim 1, wherein the modulator is finasteride or dutasteride or a pharmaceutically acceptable salt thereof. 3. The method of claim 2, wherein the modulator is dutasteride. 4. The method of claim 2, wherein the modulator is finasteride. 5. The method of claim 1, wherein the androgen is testosterone or a testosterone ester. 6. The method of claim 2, wherein the androgen is selected from the group consisting of testosterone, testosterone propionate, testosterone enanthate, testosterone cypionate, testosterone undecanoate. 7. The method of claim 1, wherein said oil vehicle comprises a mineral oil. 8. The method of claim 1, wherein said oil vehicle comprises a vegetable oil or a fish oil. 9. The method of claim 1, wherein said modulator and said androgen are administered at or about the same time. 10. The method of claim 1, wherein the modulator is administered before the androgen. 11. The method of claim 1, wherein the modulator is administered after the androgen. 12. The method of claim 1, wherein the modulator and androgen are administered together. 13. The method of claim 1, wherein the subject is a male with hypogonadism. 14. The method of claim 1, wherein the subject is a male with testosterone deficiency. 15. The method of claim 1, wherein the subject is a male with a total serum testosterone level below 12 nmol/liter. 16. The method of claim 14, wherein the subject is male and the androgen is testosterone or a testosterone ester and the androgen is administered in an amount from 25 mg to 800 mg per day and the modulator is administered in an amount capable of increasing the bioavailability of the testosterone or testosterone ester by at least 30%. 17. The method of claim 16, wherein the androgen is administered in an amount from about 100 to 400 mg per day. 18. The method of claim 16, wherein the androgen is administered in an amount from 50 to 200 mg per day. 19. The method of claim 16, wherein the androgen is administered in an amount from 25 to 100 mg per day. 20. The method of claim 16, wherein the modulator is dutasteride or finasteride. 21. The method of claim 1, wherein the subject is male adult or male adolescent. 22. The method of claim 1, wherein the subject is a female adult or female adolescent. 23. The method of claim 1, wherein the testosterone precursor is 4-androstenediol or 4-androstenedione. 24. A method of enhancing the bioavailability of testosterone in a subject who is to receive an oral dose of an androgen formulated in an oil vehicle said method comprising administering to the subject a modulator of testosterone bioavailability of the formula: wherein R1 is hydrogen or lower alkyl, and R2 is optionally substituted alkyl or optionally substituted phenyl wherein the phenyl has 0, 1, 2, or 3 substituents selected from the group consisting of lower alkyl, halogen, and trifluoromethyl, and R3, R4, R5n, and R6 are independently selected from the group consisting of hydrogen and optionally substituted lower alkyl, and the bond between adjacent carbon atom a and carbon atom b can optionally be replaced by a single bond in which the adjacent carbons are independently substituted with hydrogen or methyl, and the pharmaceutically acceptable salts thereof; and wherein the androgen is selected from the group consisting of testosterone, testosterone esters, and testosterone precursors. 25. The method of claim 24, wherein the modulator is finasteride or dutasteride and the androgen is testosterone or a testosterone ester. 26. A pharmaceutical composition comprising an oil vehicle containing 1) testosterone, testosterone ester or a testosterone precursor and 2) a modulator of testosterone bioavailability of the formula: wherein R1 is hydrogen or lower alkyl, and R2 is optionally substituted alkyl or optionally substituted phenyl wherein the phenyl has 0, 1, 2, or 3 substituents selected from the group consisting of lower alkyl, halogen, and trifluoromethyl, and R3, R4, R5, and R6 are independently selected from the group consisting of hydrogen and optionally substituted lower alkyl, and the bond between adjacent carbon atom a and carbon atom can optionally be replaced by a single bond in which the adjacent carbons are independently substituted with hydrogen or methyl, and the pharmaceutically acceptable salts thereof; and wherein the composition is in an oral formulation. 27. The composition of claim 26 wherein the modulator is finasteride or dutasteride and the androgen is testosterone or a testosterone ester and the composition is encapsulated.
