Factors affecting testosterone levels may include: Age: Testosterone levels gradually reduce as men age. [162] [163] This effect is sometimes referred to as andropause or late-onset hypogonadism. [164] Exercise: Resistance training increases testosterone levels acutely, [165] however, in older men, that increase can be avoided by protein ...

Normal total testosterone levels depend on the man's age but generally range from 240 to 950 ng/dL (nanograms per deciliter) or 8.3-32.9 nmol/L (nanomoles per liter). [11] According to American Urological Association, the diagnosis of low testosterone can be supported when the total testosterone level is below 300 ng/dl. [12]
Free androgen index. Free Androgen Index ( FAI) is a ratio used to determine abnormal androgen status in humans. The ratio is the total testosterone level divided by the sex hormone binding globulin (SHBG) level, and then multiplying by a constant, usually 100. The concentrations of testosterone and SHBG are normally measured in nanomols per liter.
As men get older, declining testosterone levels are as inevitable as death and taxes. Around the age of 30, men's T levels start to dwindle by about 1 percent a year.
