In recent years as people’s living standards continue to improve and the thirst for health knowledge, more and more people are becoming concerned about male reproductive health. Because of the special nature of male reproductive health, people are becoming more and more concerned about prostate disease. The actual prostate gland is a kind of organ? What is the role of the prostate in the human body? And what diseases are prone to occur? The actual fact is that you can find a lot of people who are not able to get the best out of the actual web site. The following is a brief discussion of this knowledge to facilitate the prevention and treatment of disease for all men. A. Overview The prostate gland is unique to men and is one of the largest substantial organs of the male genital gland. The development of the prostate depends on androgens, which means that there must be normal testicular secretion of androgens for the prostate to develop properly. The prostate gland is shaped like a chestnut, wide at the top and narrow at the bottom, slightly flat, light red and slightly grayish, about 3 to 4 cm in young adults, weighing about 20 g. The urethra and ejaculatory ducts penetrate it, consisting mainly of glands and stroma. The glandular tissue consists of 30~50 tubular vesicular glands, which then converge into 15~30 ducts that open directly on both sides of the seminal caruncle. The prostatic fluid accounts for 30% of the semen, and the role of the components it secretes is not fully understood. It is thought that the main ones are anti-microbial, sperm protection, liquefaction of semen, activation of sperm, etc. The common diseases of the prostate gland are prostatitis, benign prostatic hyperplasia and prostate cancer. The following is an introduction to each of the two, prostatitis Prostatitis is one of the common diseases in adult men, 50% of men are affected by prostatitis at some point in their lives. The original classification was acute bacterial prostatitis (ABP), chronic bacterial prostatitis (CBP), chronic sterile prostatitis/chronic pelvic pain syndrome (CP/CPPS), and asymptomatic prostatitis (AIP). in 1995 the National Institutes of Health (NIH) developed a new classification In 1995, the National Institutes of Health (NIH) developed a new classification, which is divided into four types, Type I (ABP), Type II (CBP), Type III (CP/CPPS), and Type IV (AIP). Among them, type III (chronic prostatitis/chronic pelvic pain syndrome) is the most common type of prostatitis, accounting for about 90% or more of chronic prostatitis, and this type of prostatitis is highlighted here. The pathogenesis of chronic prostatitis/chronic pelvic pain syndrome is unknown and the cause is very complex, most experts believe it is a combination of pathogenic infection, inflammation and abnormal pelvic floor neuromuscular activity. The main clinical manifestation is long-term, recurrent pain or discomfort in the pelvic region, which can be seen in the perineum, penis, perianal region, urethra, pubic bone or lumbosacral region; it can be accompanied by urinary symptoms (urinary urgency, frequency, painful urination and increased nocturia, etc.), which seriously affects the quality of life and can be accompanied by sexual dysfunction, anxiety, depression, insomnia and memory loss. Its diagnostic methods include physical examination, routine examination of prostate fluid, bacteriological examination, ultrasound, cystourethroscopy, etc., but it lacks an objective and specific diagnostic basis. For treatment, prostatitis is treated in a comprehensive manner. The goal of treatment is mainly to relieve pain, improve urinary symptoms, and improve quality of life. The degree of symptom relief is the main basis for evaluating the effectiveness of treatment. Although there are numerous treatment methods or drugs, none of them can achieve the goal of treating all patients or relieving all symptoms. Specific treatment methods are divided into: general treatment: health education, psychological counseling, abstaining from alcohol, avoiding spicy and stimulating food; avoiding holding urine, being sedentary, keeping warm and strengthening exercise. Drug treatment includes antibiotics, a~receptor blockers and non-steroidal anti-inflammatory analgesics. There are also Chinese herbal medicine, massage, heat therapy, biofeedback, etc. Important triggers for the onset of prostatitis are alcoholism, spicy food, inappropriate sexual activity, sedentary, cold, overwork, idiosyncratic body, long-term chronic squeezing of the pelvic floor muscles, catheterization, and other medically induced damage. The actual fact is that you can avoid the above-mentioned situations in your life, which can reduce the occurrence of prostatitis. Three, benign prostatic hyperplasia, also known as prostate hypertrophy, is the most common disease that causes urinary disorders in middle-aged and older men. The initial usually occurs after the age of 40, the incidence is greater than 50% at the age of 60 and up to 83% at the age of 80. Two important conditions must be present for prostate enlargement to occur: advancing age and functioning testes. The earliest symptom that appears is frequent urination, starting with increased nocturia. The most important is difficulty in urination, delayed and intermittent waiting for urination, thin and weak urine line, short range, terminal dripping, incomplete urination, prolonged urination time, and even urinary retention and bilateral hydronephrosis. The diagnosis is mainly rectal examination, imaging, urodynamics and endoscopy. Treatment is mainly watchful waiting, drug therapy and surgical treatment. Benign prostatic hyperplasia is a slowly progressive benign disease with symptoms that worsen with age and corresponding complications. Any stage of the disease process can be aggravated by climate change, exertion, alcohol consumption, constipation, sedentary and other factors, and even urinary retention. You should pay attention to the above factors in your daily life and seek medical attention as soon as the symptoms are more obvious. The incidence of prostate cancer has significant geographical and racial differences, with the highest incidence in the Caribbean and Scandinavia, and the lowest incidence in China, Japan and the former Soviet Union. In the United States, prostate cancer has overtaken lung cancer as the first tumor that affects men. In China, the incidence has increased significantly in recent years. The disease occurs mainly in older men, with a median age of 72 years for new diagnoses. The risk factors for prostate cancer are not yet clear, but some have been identified, the most important being genetics. A diet high in animal fat is a very important risk factor, and others are low intake of vitamin E, selenium, lignans, and isoflavones. Clinical manifestations: early asymptomatic, with symptoms of lower urinary tract obstruction or irritation, acute urinary retention, hematuria, and urinary incontinence when severe development occurs; bone metastases. Rectal examination and blood PSA test are the best screening methods to detect prostate cancer; also ultrasonography, CT/MRI. prostate puncture biopsy is the most reliable test. Treatment options are: watchful waiting treatment, for patients with low-risk prostate cancer and short life expectancy; radical surgery for prostate cancer; endocrine therapy (surgery and/or drugs), as the primary treatment; radiotherapy or chemotherapy. Genetics is the most important in the development of prostate cancer; in addition, reducing the intake of animal fats and increasing the intake of fruits, cereals, vegetables, and red wine may reduce the risk of development; long-term consumption of green tea may be a preventive factor against prostate cancer, and sunlight may be a protective factor.
