Abstract
On studying androgenicity of vitamins the following results were obtained:
Vitamins E and A possess androgenic property and act synergistically with testosterone on increasing the seminal vesicle weight of castrated male rats.
Vitamin B12 also exhibit androgenic activity but has no effect on the action of testosterone.
On the other hand vitamin C though possesses no androgenic properties yet it acts synergistically with testosterone.
As regards vitamin B6, it has neither androgenic property nor synergistic action with testosterone.
