The existence of andropause is recognised by some of the best researchers in medical science, including the international medical community. In fact, a recent World Health Organization (WHO) report, states that “male androgens progressively decline with age.” The study tested androgen levels at age 25 and by age 70, androgen levels were only 10 percent of what they were during youth. The impact of decreasing androgens is known as andropause, also called "male menopause" or PADAM – Partial Androgen Deficiency in the Ageing Male. It is a normal part of ageing, although, for some men it is accompanied by a gradual and undesired decline in their sexuality, mood and overall energy. Sometimes it can even expose men to more serious health risks. As with women, andropause in males begins at a time when life often offers some of its greatest rewards. ============= wikipedia: Andropause is a medical phenomenon, similar to the female menopause, that can affect men between the ages of 40 and 55. Unlike women, men do not have a clear-cut signpost such as the cessation of menstruation to mark this transition. Both, however, are distinguished by a drop in hormone levels--estrogen in women, testosterone in men. The bodily changes occur very gradually in men and may be accompanied by changes in attitudes and moods, fatigue, a loss of energy, sex drive and physical agility. Studies show that this decline in testosterone can put men at risk for other health problems such as heart disease and weak bones. Unlike menopause, which generally occurs in women during their mid-forties to mid-fifties, men's "transition" may be much more gradual and expand over many decades. Attitude, psychological stress, alcohol, injuries or surgery, medications, obesity and infections can contribute to its onset. Although with age, a decline in testosterone levels will occur in virtually all men, there is no way of predicting who will experience andropausal symptoms of sufficient severity to seek medical help. Neither is it predictable at what age symptoms will occur in a particular individual. Each man's symptoms may also be different. Andropause routinely escapes diagnosis because symptoms can be vague and can vary greatly among individuals. Furthermore, while the female analog of this life change has a distinctive and sudden onset, production of the male hormone begins to decline as early as age 30 and proceeds over the next three, four or five decades until death. While the creeping symptoms of andropause are often dismissed by both patients and professionals as "what happens as we age" some have begun to consider them as signs of a disease state of which premature aging is merely another symptom. A diagnosis of Hypogonadism (also seen in younger men) often serves as a gateway to consideration of the broader condition. Once the condition is discovered, it is a straightforward (although somewhat involved) process of replacing the missing testosterone by injection, locally applied hormone gel, trans-dermal patch or implanted cartridge. The complicating factor in male hormone replacement is found in the highly individual nature of what is considered normal. Any given man could function optimally at a blood level one-half to one-third of another. In hormone replacement more is not better since an excess of testosterone beyond a man's customary blood levels can have quite unpleasant and even dangerous effects. Medical supervision is a must. ====== hope this helps
