Male infertility is a condition that results from one or more disease factors, physical and chemical factors and poor lifestyle acting on numerous links. There is a multiplier effect between them, which means that one factor will amplify the effect of another factor, playing a 1 + 1 greater than 2 effect; conversely, if one of these factors is reduced, it may play an effect that is not only in itself, but may weaken the intensity of the other factors, which brings us a big step closer to the eventual acquisition of fertility. It is valuable to understand these factors and to treat them positively. Some factors are actually relatively easy to avoid. The main components of male infertility care include: timely detection and correction of diseases that affect fertility, avoiding the use of drugs with reproductive toxicity, circumventing physical and chemical factors in the environment that affect the reproductive function of the testicles, changing poor lifestyles that affect the reproductive function of the testicles, and adjusting the mindset. 1, timely detection and correction of diseases that affect fertility. Many disease factors can impair reproductive function, including: congenital abnormalities of the testes (such as cryptorchidism, Crohn’s syndrome), systemic diseases (high fever in the last 6 months, diabetes, neurological diseases, chronic wasting diseases such as liver cirrhosis, kidney failure, tuberculosis, malnutrition), sexually transmitted diseases (syphilis, gonorrhea, chlamydia, mycoplasma), accessory gonadal infections (prostatitis/ seminal vesiculitis/ epididymitis) (prostatitis/ seminal vesicle tuberculosis/ epididymal tuberculosis, circumcision glansitis of Gardnerella infection), testicular acquired disease (post-pubertal mumps, other orchitis, testicular injury, testicular torsion), varicocele, vas deferens obstruction (infection, congenital defect, injury, testicular level obstruction), endocrine abnormalities (e.g. pituitary tumors, hyperprolactinemia), surgical history ( urethral stricture surgery, superior/inferior urethral cleft surgery, infantile urethral valve surgery, prostate surgery, bladder neck surgery, sympathectomy N, larger retroperitoneal surgery, vasectomy, syringomyelia surgery, inguinal hernia repair), etc. Some of these factors affect the function of the testicular varicocele, so that sperm production is affected; some affect the function of the accessory gonads; some cause obstruction of the reproductive ducts, preventing the normal transport of sperm; some cause sexual and ejaculatory dysfunction, so that sperm cannot be transported to the female partner. 2. Avoid the use of drugs with reproductive toxicity. Such as anti-cancer drugs, corticosteroids, cyclosporine, memantine, furantin, gentamicin, reserpine, estrogen, cimetidine, cottonseed oil, anti-rheumatic drugs tretinoin, etc. 3, circumvent the chemical toxic substances in the environment that affect the reproductive function of the testicles. Toxic substances in the environment act on the human body, the more sensitive reproductive system in the human body naturally suffer from it. Such as metal lead, cadmium, manganese, mercury, arsenic, etc. can directly or indirectly damage the function of the testes; followed by pesticides. Not only damage the health of pesticide users, but also through polluted water, air, soil and agricultural by-products so that more people suffer from pesticide poisoning; there are rust remover, food additives, food coloring agents, laundry detergent, detergent, cosmetics, etc., may damage the spermatogenic function of the testes. 4, circumvent the physical factors in the environment that affect the reproductive function of the testicles. The most common is heat (such as fever, high-temperature operations such as furnace front workers). Heat can cause damage to the testicular spermatogenic epithelium, cell degeneration and shedding, and spermatogenesis is hindered. In reality, the testes of workers who are under long-term high-temperature work are functionally impaired due to heat, and the quality of semen decreases, resulting in infertility. Radiation, electromagnetic radiation (such as computer, TV, cell phone, etc.), X-rays, microwave ovens, etc. Spermatogenic cells are particularly sensitive to radiation, resulting in inhibition or permanent damage to the spermatogenic epithelium. Electron fog can easily lead to severe abnormalities of spermatogenic cells in electron fog-sensitive individuals. As microwave and infrared rays can produce thermal effects, the effect on the testes can also produce similar heat-like destructive effects. 5, change the bad lifestyle that affects the reproductive function of the testicles. People who like to wear tight pants (such as jeans), so that the testicles close to the abdomen, the scrotum does not stretch, resulting in the scrotal temperature increases, because the scrotum is not easy to dissipate heat, their testicles are susceptible to the effects of heat, impaired function and lower semen quality; drivers for a long time to clip legs, long time to ride a bicycle, so that the testicles are hot baked for several hours a day; sauna or the use of hot tubs, so that the temperature of the scrotum increases, testicular spermatogenic function is impaired will also lead to infertility, and a drop in sperm count in a sauna lasts 1 to 2 weeks. Obesity, alcohol abuse, smoking, drug use, and extreme sports (marathon training, super-intense exercise) can affect male fertility. Long-term smokers have lower sperm density and viability and an increased rate of malformed sperm. Alcohol abuse can cause testicular spermatogenesis disorders and decreased semen quality. Drugs a spermatogenic epithelium off; two make a significant reduction in interstitial cells, testosterone levels drop. 6, adjust the mentality. Increased social and family burdens, complex interpersonal relationships, pressure from around the fertility, emotional stress and anxiety depression, will affect the reproductive function of the testes through psychological factors, such as strong anxiety can cause ovulation disorders in women, uterine contractions to miscarriage, male spermatogenic function abnormalities. 7, other. Stay away from smoke and dust, avoid sedentary and stay up late, reduce mechanical vibration, reduce the intake of coffee, cola and fried food, increase the intake of fruits and vegetables. Increase the intake of unheated milk (i.e. milk at room temperature that can be consumed directly), fried tomatoes in oil, various kinds of sub-foods, coarse grains, etc. as appropriate. To increase the chances of conception one should have some knowledge about general reproduction and should encourage people to make efforts to acquire scientific knowledge about reproduction. Some diseases that cause testicular dysfunction are treatable and these should be actively treated, and reducing one factor is one step closer to eventually gaining fertility. The factors in life that lead to infertility are variable and preventable, so one should try to avoid the various risk factors that may lead to infertility.
