August 10, 2001 – New scientific research has identified a physiological cause for andropause. Researchers at Penn State University in Pennsylvania looked at this phenomenon often observed in aging men, but never scientifically proven. Dr Laurence Demers, chemist and head of research, hypothesized that, like women who have a menopause linked to a decrease in estrogen levels, men would experience andropause associated with a decrease in the rate. of testosterone.
Thus, it is estimated that from the age of 30, the testosterone level in a man decreases by 10% every ten years. Researchers believe that andropause could begin to manifest between the ages of 40 and 55, with the difference that, in men, there is no physical sign as tangible as the cessation of menstruation in women. Dr. Demers notes, however, that the overwhelming popularity of Viagra could be a sign of significant libido problems in a large number of men.
In his research, Dr. Demers also found that levels of testosterone and steroid hormones related to the development of male secondary sex characteristics could vary by ethnicity. In a study of men of Portuguese, American and Asian origins, it was found that testosterone levels are highest among Portuguese people. Then follow, respectively, the Americans and Asians. As regards the level of steroid hormones which are responsible, in particular, for hair growth, the differences were even more marked: Asians have the least. They are generally less bearded and less hairy than the Americans, who are themselves less bearded than the Portuguese.
However, this research needs to be deepened. It is estimated that the transformations associated with andropause occur very gradually in the human body and take place over several decades. They can take all kinds of forms: mood swings, changes in posture, loss of energy, decreased sexual appetite, or infertility. These changes can lead to other types of problems, including weakened bones and heart disease. Stress, alcohol, obesity, injuries and surgeries are all factors that would contribute to an early onset of andropause. According to the researchers, 30% of men have testosterone levels low enough to experience the symptoms of andropause or develop a disease related to it.
