Age-related hormonal changes do not only affect women going through menopause. Men also experience a decline in sex-hormone production as they age, often showing symptoms of andropause, or "male menopause," especially in the fall and winter months when exposure to sunlight decreases.
In a 2010 study of 2,000 men aged 40 and above nationwide, the Korean Society for Sexual Medicine and Andrology found that 28.4 percent of the men had low levels of testosterone. A man's testosterone levels typically peak in his early 30s, then gradually decline, reaching about 60 percent of former levels at the age of 75.
Andropause can lead to sexual health problems such as erectile dysfunction and reduced libido. More common symptoms include lethargy, anxiety, depression, hair loss and insomnia, all of which can disrupt everyday life.
Initial treatment of andropause usually involves supplementing testosterone levels using injections or pills. These are administered for about six to 12 months to improve the testicular capacity for testosterone production.
Along with hormone therapy, it is important to maintain a healthy lifestyle by exercising, not smoking, drinking in moderation, and eating a balanced diet that includes fish like mackerel and tuna, while avoiding fatty foods and overeating. Stress should be minimized, as it reduces testosterone production.
