Since ancient times, many people have tried every means to find various sexual stimulants, but they often have little effect, or even though they work for a while, they have many side effects. Since sexual function has a certain relationship with sex hormones, sex hormones were often used as sexual stimulants in the past. Many traditional Chinese medicine "aphrodisiacs" also have effects similar to sex hormones. For some men who lack testosterone, using androgens and traditional Chinese medicine "aphrodisiacs" can restore sexual desire and sexual ability to normal levels. But for most men with normal testosterone levels, androgens have no such effect. Some normal people can slightly enhance their sexual desire after taking medication, which is actually a function of psychological factors. Because some androgens can be metabolized into estrogens in male blood circulation, they can cause male breast enlargement in some people, similar to that in women. Long-term use of androgens and similar drugs may also cause prostatic hypertrophy, induce prostate cancer, and aggravate atherosclerosis. Women's use of androgens can enhance sexual response, but can cause side effects such as hirsutism, acne, and clitoromegaly. Estrogen does not enhance sexual desire for ordinary women; for menopausal women, due to estrogen deficiency, supplementing small doses of estrogen can reduce osteoporosis and the risk of coronary heart disease, while maintaining vaginal lubrication and vaginal mucosa. integrity and plump breasts. Topical estrogen ointment applied to the vagina and clitoris is also effective in slowing down vaginal atrophy, maintaining vaginal lubrication, and reducing pain and discomfort during sexual intercourse. However, excessive dosage of estrogen may induce uterine cancer and breast cancer.

Because sex hormones have the above-mentioned side effects, their application is greatly limited and is only suitable for a small number of people with low sex hormone levels. There is a neurological disease called Parkinson's disease, which is a common disease among the elderly and is currently popularly treated with levodopa. Levodopa is converted into dopamine in the body. Treatment with levodopa has been reported to cause hypersexuality. Animal experiments show that increasing levodopa can extend the average life span of mice and delay aging to a certain extent. Although these studies are preliminary, they have opened up ways to prolong sexual youth and delay the aging of life. However, the actual application in humans requires further in-depth research. Long-term avoidance of sexual life can cause disuse atrophy: elderly women are prone to vaginal atrophy, and men are prone to impotence. Research shows that couples who have regular and harmonious sexual life can prolong puberty and maintain normal sexual function in old age. Neither indulgence nor abstinence is in line with longevity and beneficial to physical and mental health.

A healthy body and a reasonable diet are also necessary to delay puberty. People who are in good health can still maintain sexual fertility until they are seventy or eighty years old. Diabetes, liver cirrhosis, uremia and other diseases themselves can also affect sexual function. Comprehensive and reasonable nutrition is also very important, especially the trace element zinc, which can directly affect the gonads. Zinc deficiency can cause testicular atrophy and sperm reduction.

Research on many kidney-tonifying Chinese medicines found that these drugs can improve gonadal function. Tai Chi also has similar effects and has special effects on prolonging puberty and delaying aging.
