In the work of the reproductive male clinic, we often encounter some patients and even non-specialists are not enough attention but more important issues, if not informed in a timely manner and the correct treatment may cause patients to take more detours or even delay the diagnosis and treatment, the following is a brief overview of these issues: a. What is infertility? Theoretically, men only need to have a normal healthy sperm in order to have a successful pregnancy, so it takes less than a year to try to conceive. It is not very meaningful to judge whether the pregnancy is conceived or not based on the numbers on the report card. There is also a situation when the female partner is over 35 years old, this time the attitude should be more positive, because the female age has a greater impact on the quality of eggs, this situation is not contraceptive for more than six months without success can enter the treatment phase. We stipulate that you should abstain from sex for more than 48 hours before sperm retrieval, as there is a process of sperm maturation, and the number of sperm may be low if the time is too short, but it is best not to exceed 1 week, as the sperm may age and lose vitality if the abstinence time is too long. In most cases, the semen missed is the front part of the semen, which contains the largest number of sperm and the best quality, and incomplete specimens may affect the accuracy of the results. The standard treatment course is 3 months, because it takes more than 70 days for sperm to mature, so it is better to cover the whole sperm production cycle. It is recommended to adhere to the treatment for 1 to 2 courses, if the effect of regular drug treatment is not satisfactory, you can consider choosing assisted reproductive technology to help conceive. IV. Attention should be paid to the problem of semen non-liquefaction Semen viscosity and prolonged liquefaction is a very common semen abnormality, often not as much attention as indicators such as quantity and vitality, but it is also likely to affect pregnancy, because sperm have a greater resistance to swim in seminal plasma with high viscosity, and when sperm lack sufficient forward momentum it will increase the difficulty of encountering eggs, thus reducing the probability of pregnancy. The sluggish liquefaction of semen is often indicative of poor prostate secretion, which should be further examined. Appropriate zinc supplementation and antioxidants such as vitamin C can improve the situation to some extent, and some antibiotic treatment is also beneficial if inflammation exists. Male factors associated with repeated early miscarriage/embryonic abortion For early miscarriage or embryonic abortion more than twice, it is recommended that the male partner should undergo three tests: chromosomal, sperm maturity and geodetic anemia to exclude the male partner’s factors that lead to embryo quality decline. The first thing you need to do is to quit smoking and drinking, avoid being sedentary, stay up late, don’t wear tight pants, less hot springs and saunas, and try to stay away from high temperatures, strong radiation and chemical toxic pollution, and certain occupations such as drivers, chefs, and renovators are recommended to change the working environment temporarily. Learn to reduce stress and relax, moderate fitness exercise, eat more high-protein and zinc-rich, vitamin-rich food, such as a variety of meat, seafood, eggs and milk, nuts, apples, tomatoes and so on. Of course, an adequate and regular sex life is also a necessary condition for successful conception.
