normal menstrual cycleThis report describes the free or unbound testosterone levels in ten normal females during the menstrual cycle, using a simplified technique of equilibrium dialysis of undiluted plasma. Total testosterone concentration fell progressively during the menstrual cycle, whereas the percent ...
Healthy young and middle-aged women participated during the early follicular phase of the menstrual cycle, and amygdala responses to biologically salient stimuli were measured with functional magnetic resonance imaging (fMRI).

What are considered “normal” levels vary from individual to individual and in the individual themselves depending on several factors: Testosterone levels vary during the menstrual cycle as do other sex hormones, testosterone peaks during the middle phase of the cycle around the time of ovulation; ...
The use of a sensitive equilibrium dialysis method for the measurement of free testosterone levels in healthy, cycling women and in human immunodeficiency ... in women to define the range for these hormones during the normal menstrual cycle and assess the total and free testosterone levels in HIV...

testosterone levels unless there is complete disruption of the sleep architecture preventing the initial increase in testosterone during the first REM cycle.30,31There has been substantial interest in assessing circannual variations in serum testosterone levels in men. The data are overall conflicting, ...
While levels of estrogen fluctuate during the menstrual cycle, the hormone is produced consistently until menopause, when it decreases dramatically, causing hot flashes, sleep issues and a host of other problems. Women’s testosterone levels, on the other hand, peak during one’s teens and 20s ...
