Low testosterone levels predict all-cause mortality and cardiovascular events in women

A study in a large primary care patient population shows that low baseline testosterone in women aged 43-72 years is associated with increased all-cause mortality and cardiovascular events. This association was found to be largely independent of traditional risk factors, and supports the notion that the hormonal status in middle age and older women might impact morality outcomes.

The objective of the study was to determine whether baseline testosterone levels in women are associated with future overall or cardiovascular morbidity and mortality.

Low free testosterone levels and loss of muscle mass

Hypogonadism, aka testosterone deficiency or low-T, is primarily diagnosed by low total testosterone levels. However, more and more research is showing that free testosterone, which is the active fraction of total circulating testosterone, is independently associated with important health outcomes.

Levels of free testosterone decline more steeply than total testosterone as menage.[1-7 In many cases, total testosterone levels can be relatively high, but free testosterone low. Therefore it is important to assess both total and free testosterone levels in order to get a clear picture of the androgen status.

A recent study specifically assessed if baseline testosterone (total and free) levels predict muscle loss in middle-aged and elderly Japanese men over a 10 year period.[8]
