We report here on a 26-year-old pregnant female who developed hirsutism and virilization during her third trimester along with a significantly elevated serum testosterone level. Abdominal US and MR imaging studies were performed, and they showed unique imaging features that may suggest the diagnosis of pregnancy luteoma in the clinical context. After the delivery, the serum testosterone level c...

the effects of exposure to chemical weapons containing sulfur mustards on the serum levels of total and free testosterone. gonadotropins and prolactin was investigated in young iranian men. in the first five weeks after injury both serum total and free testosterone were significantly decreased as compared to control values. three of 13 men had total testosterone below 300 ng/dl and two of six h...

Aim The Aging process is a major risk factor for the development of degenerative diseases, including cognitive impairment. Many studies have shown that reduced cognitive function is associated with low testosterone levels. This study was aimed to know the association between serum testosterone level and cognitive functions in men who showed mild cognitive impairment. Method This was a cross-sec...

The proposed key symptoms of the female androgen insufficiency syndrome (FAIS) include reduced libido, diminished well being and lowered mood. The diagnosis of FAIS is made on the basis of these symptoms in the setting of a low serum free testosterone level. However, there is currently no readily available inexpensive assay which reliably measures free testosterone levels in the female range. T...
