Sexual aging in men in their 50s may be characterized by changes in the appearance of the penis, decreased sensitivity, and contraction of the testicles. 1. Changes in the appearance of the penis: as men age, androgen levels decrease, pubic hair on the penis decreases, and the epidermis of the penis loosens. 2. Decreased sensitivity: men may experience sexual aging such as a decrease in the number of sexual impulses, delayed sexual response, and extreme fatigue after sex. 3. Testicular contraction: as men age, the interstitial cells of the testes will gradually age, testosterone secretion will decrease significantly, and the volume of the testes will also decrease relatively. Sexual aging is a normal physiological phenomenon in men at the age of 50, if there is a sexual need or other discomforts accompanying the process of sexual aging, it is recommended to go to the hospital in time for diagnosis and treatment.
