Any time I have been manic/hypomanic sex drive goes out the roof and I know that increased sex drive is a trait if higher testosterone... just wondering if anyone knew if there was any correlation?

However, it looks like mania is associated with a very large increase in LH. And I don't mean me, I mean leutenizing hormone. Heh.

Selective increase in plasma luteinising hormone concentrations in drug free young men with mania.
Whalley LJ, Christie JE, Bennie J, Dick H, Blackburn IM, Blackwood D, Sanchez Watts G, Fink G.
The hypothalamic-pituitary-gonadal system was investigated in drug free young men with either mania or acute schizophrenia and in age matched controls by measuring, at frequent intervals during a 17 hour "neuroendocrine day," plasma concentrations of luteinising hormone (LH), follicle stimulating hormone, prolactin, testosterone, sex hormone binding globulin (SHBG), and cortisol. Plasma LH in mania was significantly increased compared with the control value at all time periods and increased in the morning and evening samples compared with values in the schizophrenic patients. Plasma prolactin and cortisol concentrations were significantly greater in mania and schizophrenia compared with control values at several times during the day, but there were no significant between group differences in plasma testosterone or SHBG. These results show that in young men with mania there is a major disturbance in the central mechanisms that control the release of LH, the control of prolactin and cortisol secretion is abnormal in mania and acute schizophrenia, and plasma LH concentrations may provide a useful hormonal diagnostic test for mania.

A common denominator between the two may also be an increased limbic dopaminergic or noradrenergic neurotransmission.

Ok guys, I am certain I do not know near as much about brain chemistry as you, but judging from the article it said there was no increase of testosterone in manic people, but a large increase in lutenizing hormone (LH) ... doesn't an increased amount of LH usually trigger the generation of more testosterone?
The reason I asked this in the first place .. was .., I was reading posts of people who did testosterone treatment and the "improvements" it caused sure sounded a lot like some hypoomanic symptoms : more energy, higher sex drive, more decisive, quicker temper, throwing caution to the wind and "going for it",etc ... anyway, just thought the two sounded somewhat similar.
