New study, SWAN study, finds that bioavailable Testosterone was "significantly positively related" to visceral fat.  As bioavailable Testosterone increases in post-menopausal women, visceral fat increases.  The authors conclude that Testosterone increases visceral fat accumulation.  This increased Testosterone is concluded to be from a decrease in SHBG as a result of falling Estradiol.

Re-analysis of Carlsen's work on sperm count finds consistent decline in sperm count.  Swan and authors found a 1.5% decline in US men from 1934-1996 and 3% annual decline in European/Australian men over same time frame.  This was a meta-analysis of 101 studies from 1934-1996.  Yes, there is geographical variation, but the overall trend is one of decline.

A decrease in the SHBG in post menopause women is associated with increase in free Testosterone, which is associated with increase in MetS and CVD

declining serum Estradiol associated with increased cardiovascular fat in postmenopausal women.

The opposite effect strikes again: elevated free androgen index is associated with CV risk in perimenopause women across 5 ethnic groups.  Low SHBG was associated with increased CVD.
