...eterosexual women. The blood samples revealed that hormones such as testosterone, androstenedione, free testosterone index and luteinizing hormone (LH) were significantly higher, and sex hormone binding globulin (SHBG)[3] was significantly lower in lesbian women compared with heterosexual women.
