Andropause refers to a gradual decline in testosterone levels in aging men, often starting in their late 30s to early 40s. Unlike menopause in women, which occurs over a relatively short period, andropause is a slow process that can last for years. Symptoms may include fatigue, mood changes, reduced libido, and difficulty concentrating. This condition is not universally experienced by all men, and its severity can vary widely. While some may notice significant changes, others may have minimal or no symptoms. Lifestyle factors, such as diet and exercise, can also influence the effects of andropause.
