Subgroup analysis for assay type was statistically significant for spontaneous POI only .
Sensitivity analyses of high- quality studies did not change the results , and result ed in a substantial decrease in heterogeneity in spontaneous POI studies .
The current meta- analysis demonstrates that total testosterone concentrations are decreased in women with spontaneous POI or iatrogenic menopause .
BACKGROUND Increasing age and post-menopausal status are associated with decreasing and rogen concentrations in females .
Women with premature loss of ovarian function , such as primary ovarian insufficiency ( POI ) or iatrogenic menopause may be at increased risk for diminished testosterone levels at a relatively young age .
Differentiation between a hypo and rogenic or normo and rogenic state in women with premature loss of ovarian function is problematic due to trueness and precision problems using various testosterone assays .
The current meta- analysis was conducted to evaluate current literature reporting serum total testosterone concentrations under these conditions , including stratification for various testosterone assays .
The effect of oophorectomy and hormone replacement on neurohypophyseal hormone secretion in women
OBJECTIVE There is evidence to suggest that the release of neurohypophyseal hormones may be influenced by the circulating concentrations of gonadal steroids . We therefore monitored this relationship in women undergoing prophylactic bilateral oophorectomy at the time of hysterectomy with subsequent hormone replacement therapy  and compared it with that in women undergoing hysterectomy with conservation of
