Male Factor 1
Testosterone!
Testosterone levels start to decrease around the age of thirty. Free testosterone levels decrease by 1-2% per year on average. These levels decrease by 50-60% between the ages of twenty-five and seventy-five, which is a normal process. A decrease in testosterone levels can cause physical and psychological symptoms.
If you feel fatigued and you have a hard time recovering after physical activities, you may be experiencing a reduction in testosterone.
