Gamma oryzanol is also often promoted for treating menopause, but it is unclear how it would work for this use. Some researchers suspect it might be helpful due to effects on luteinizing hormone (LH). However, this effect has not been shown in people.
Some people use gamma oryzanol for increasing testosterone and growth hormone levels. However, gamma oryzanol appears to have no effect on these hormone levels. In fact, animal studies suggest that gamma oryzanol might even reduce testosterone production.
