Men do not experience a well-defined phase of menopause, but the decline in testosterone or androgen levels in males is commonly referred to as Andropause. In this article, we will discuss the causes, signs, symptoms, and treatment options of this condition . Unlike menopause, which is a universal phenomenon in women and results in complete gonadal failure over time, Andropause (also called male climacteric, androgen, male menopause, androclise decline in aging male or ADAM, delayed onset of hypogonadism or LOH, and aging male syndrome) is characterized by low testosterone levels in older men, or men who have lost testicular function due to illnesses, accidents, or surgical or medical castration caused by advanced prostate cancer. Some health experts believe that the term "male menopause" is misleading since although testosterone levels decrease as men age, the decline is gradual, usually less than 2% per year from age 30 to 40, and will not really cause any issues on its own. However, a testosterone deficiency and late-onset hypogonadism isn’t really a normal part of the aging process.
