High SHBG may do that.

Are you taking oral contraceptives or acne medication?

How is your blood sugar? High insulin can also affect it.

Hyperthyroid can also cause that.

i am thin with high blood fasting blood sugar and a LOT of stress. i am not hyperthyroid..if anything hypothyroid at the time i tested this my tsh was 4.something..higher than it's ever been. recently i went VLC and im thinking i went a little overboard. a few months ago (not vlc) my testosterone (total) was normal..unfortunately i didnt test free. hrmm – holly Jan 2 2012 at 16:11
ncbi.nlm.nih.gov/pubmed/7962291 It is known that there is an inverse relationship between the serum levels of insulin and sex hormone-binding globulin (SHBG) in women, – holly Jan 2 2012 at 16:16
maybe my insulin being too low is messing with the SHBG and keeping the testosterone from being available? – holly Jan 2 2012 at 16:17

 I do not know a whole lot about this topic, but there seems to be some connection there. Do you have any autoimmune disease? Have you been gluten free? I ask because that could have an effect on your pancreatic B-cells which make insulin. In contrast, you could have some insulin resistance going on. VLC causes the body to become insulin resistant. high-fat-nutrition.blogspot.com/2007/10/… and high-fat-nutrition.blogspot.com/2009/09/… – Jeff Jan 2 2012 at 17:12

 VLC is a stressor and if you have a lot of outside stress I'd consider having ~150g carbs/day to avoid the self-induced low carb stress – Jeff Jan 2 2012 at 17:13
