1, I am a driver, suffering from oligospermia, is this related to my occupation? The driver’s profession has some effects on fertility, such as the higher local temperature of the testicles, long-term sedentary affects the local blood circulation of the testicles, long time high tension, more exposure to car exhaust and gasoline additives, and other factors may have a certain impact on the spermatogenic function of the testicles, thus causing oligozoospermia. 2.Is male fertility related to age? It is generally believed that men are basically fertile at the age of 18. The fertility of the adult until the age of 45 does not change much. After the age of 45, the fertility decreases gradually. Most men, at the age of 60, still have some fertility. 3, smoking, alcohol and staying up late will affect the quality of sperm? The most common factors that affect sperm quality are smoking, drinking and staying up late. The main toxic ingredient in tobacco is nicotine, which has the effect of reducing sex hormone secretion and killing sperm. Alcohol abuse can cause testicular sperm production dysfunction and endocrine hormone changes that affect sperm quality. The effect of staying up late on sperm is even more pronounced. Usually, when semen tests are done after a night shift, most people have abnormal results in the routine semen analysis. When the test is repeated after sufficient sleep, the results often improve significantly. 4.Is it impossible for a man to have children if he has a positive test for anti-sperm antibodies? A positive male antisperm antibody has a relatively limited effect on fertility. Usually prednisone, dexamethasone and other medications are given, and can also be treated by Chinese herbal identification. Many patients with positive anti-sperm antibodies have given birth to healthy babies without specific treatment. 5.Will the father who is a hepatitis B virus carrier infect his child? When is the best time to have a baby? The father is a carrier of hepatitis B virus, although it is possible to infect the child, but the possibility is small. It is best to conceive when the liver function is normal and the level of hepatitis B virus DNA replication is relatively low. 6.Does prolonged computer use affect male sperm quality? The amount of radiation from the computer to the human body is lower than that of the cell phone, and the impact of using the computer on male sperm is not obvious. 7. Does chronic prostatitis affect fertility? The actual fact is that there is no definite conclusion as to whether or not chronic prostatitis will affect fertility. Theoretically, when inflammation occurs in the prostate, the inflammatory changes in the prostate will cause the composition and physicochemical properties of semen to change: the amount of semen decreases, the viscosity increases, and the liquefaction time increases, affecting the survival and vitality of sperm. If bacterial prostatitis occurs, the semen will contain bacteria and toxins that inhibit the viability of sperm, thus significantly reducing male fertility. However, from clinical cases, most patients with chronic prostatitis are able to have children. A few patients are combined with infertility at the same time, but there are many reasons for infertility, such as overemphasis on chronic prostatitis, often ignoring other causes, thus delaying treatment, and may also unnecessarily aggravate the patient’s fear of the disease 8, male Mycoplasma solani infection affects fertility? The current study concluded that Mycoplasma urealyticum can be divided into more than 10 subtypes. Some subtypes have an impact on fertility; some subtypes do not usually affect fertility, in the case of local environmental changes, overgrowth, may have an impact on fertility; there are subtypes, generally considered not to affect fertility. 9.What are the methods of testicular biopsy? Which method is good? At present, there are traditional open biopsy, coarse needle aspiration biopsy, fine needle aspiration biopsy and microbiopsy methods for testicular biopsy. The first two methods are being used less and less because they are more invasive. Microscopic biopsy also has limited application due to the need for an operating microscope. More and more hospitals are now using fine needle aspiration biopsy techniques. Most of the patients who usually have testicular puncture are azoospermia patients. In terms of the size of the chances of getting sperm, microscopic sperm retrieval is the best method. 10.Does circumcision affect fertility? Circumcision does not directly affect fertility. However, long foreskin can easily breed microorganisms and cause local infection and infection in the wife’s reproductive tract, which can indirectly affect fertility.
