ANDROPAUSE: THE EVOLUTION OF MALE HORMONES
Hormones are one of the aspects of the inner workings of the body that make men and women very different from the moment we are born. The generation of hormones and their levels vary substantially between the sexes.
The term andropause is used in men to define a process similar to menopause in women, but with two fundamental differences:
- While menopause occurs between the ages of 45-55, the “transition” in men is usually slow; it may last for decades and has a different progression in each individual.
- Menopause involves an absence of fertility; andropause, on the other hand, is not necessarily related to the end of the fertile stage in men.
Andropause, also called ‘midlife crisis’, has long been attributed mainly to a deficit of testosterone – which occurs after the age of 40 – although recent research has shown that it is not only due to this hormone. Andropause has a physiological basis in the drop in plasma levels of hormones such as testosterone, DHEA, melatonin or thyroid hormone, as well as an increase in others such as cortisol and insulin.
