Serum testosterone and sex hormone binding globulin levels in women with androgenetic alopecia.

Serum levels of testosterone and sex hormone binding globulin (SHBG) were assessed in eight women suffering from male pattern alopecia. Eight healthy women of similar age served as controls. A statistically non-significant increase was observed in serum testosterone levels as compared with those of the controls (p greater than 0.1). On the other hand, a statistically significant fall was observed in serum SHBG levels as compared with those of the controls (p less than 0.001).
