Sex hormones vary between men and women, with testosterone (T) and dihydrotestosterone (DHT) in men and estrogen (E) and progesterone (P) in women. In addition, the adrenal glands of both sexes secrete small amounts of dehydroisandrosterone and androstenedione. The role of sex hormones as one of the prerequisites for the completion of sexual life is quite complex. To put it simply, there is an independent system of sex hormone control in the human body, called “hypothalamic-pituitary-gonadal axis”, for the completion of sexual physiological activities. It turns out that under the unified command of the cerebral cortex, the lower part of the thalamus produces a gonadotropin, which further gives work orders to its subordinates – the gonads. The testes of men and the ovaries of women are the gonads, which, upon receiving the orders from the pituitary gland, excel in producing androgens or estrogens, and then go on to perform the tasks of sexual physiological activities. Testosterone, the representative of androgens in men’s body, is produced in the amount of about 7 mg per day, which is 0.6 micrograms per milliliter of blood on average. Such amount can accomplish some of the following tasks: promote the growth and development of all male sexual organs and maintain their normal work; urge the testes themselves to produce sperm; induce, drive and maintain sexual desire; help complete penile erection and ejaculation actions; display male characteristics, such as a stout body, thick throat, hairy and low voice, etc. Testosterone is important for normal male sexual function, such as libido and spontaneous erection, but androgens play a minor role in erections caused by visual erotic stimulation. The role of testosterone in the central nervous system for cognitive, social and sexual behavior is still debated and needs further study. In lower animals, male aggressive behavior is associated with serum testosterone levels. DDD estradiol, a representative of estrogen in women, is produced in varying amounts depending on the menstrual cycle, with higher amounts produced in the days before and during ovulation and lower amounts after ovulation and during menstruation. The average daily amount produced is 0.2 to 0.9 micrograms. This amount can play a number of roles: promote the growth and development of all female sexual organs and maintain their normal work; urge the ovaries themselves to complete the task of egg production; induce and maintain sexual desire, help women to enter into erotic orgasm during sexual impulse, and complete the clitoral erection and throbbing, as well as help vaginal contraction and other neurological reflexes; display female characteristics, such as a beautiful body, breast bulge, skin and voice. tender skin, high pitched voice, etc. Abnormalities in sex hormones, such as decreased serum levels and hormone receptor deficiencies, can affect sexual function and require appropriate testing to identify the cause. In male clinics, due to the many causes of sexual dysfunction, some patients need androgen supplementation therapy to treat erectile dysfunction, and a few patients have certain side effects. And Chinese medicine is highly regarded for its unique efficacy and good histocompatibility. Modern pharmacological research shows that many Chinese medicines contain sex hormones, such as deer antler, epimedium, hippocampus, mealybug and zihejiang, etc. The combination of Chinese and Western medicine and evidence-based treatment of male sexual function has allowed more families to have joy.
