I. Factors affecting male fertility in couples.
1. Between couples, the one with strong fertility can compensate for the one with weak fertility. Therefore, abnormal semen parameters do not necessarily mean that you cannot have children.
2. The age of the female partner is also an important factor that affects fertility. When the female partner is older than 34 years old, she can be examined and treated after 6 months of trying to conceive without making her pregnant. Because the fertility of women aged 35, 38 and 40 is 50%, 25% and 5% of the fertility of women aged 25, respectively.
3. Pay attention to the timing of sexual intercourse, frequency, and the presence of sexual dysfunction will affect conception. The timing of sexual intercourse should be chosen during ovulation, but should not be limited to the day of predicted ovulation. Non-ovulatory period should also have appropriate frequency of sexual intercourse or other ways of ejaculation.
4. The duration of natural infertility is important for predicting its future fertility, and the more serious the problem exists if natural infertility is prolonged.
Second, the living environment, drugs and other factors that affect male fertility.
1, one of the important reasons for the declining fertility of men is the environmental factors of life and work. Through contact with contaminated diet, air, water, etc. and play a role, long or short-term exposure to heavy metals (such as lead, cadmium, mercury, aluminum, copper, manganese, etc.), chemical substances (such as pesticides, herbicides, toxic decorative materials and paints and coatings, cigarette smoke, carbon disulfide, dibromochloropropane, methyl ethyl ketone, formaldehyde, automobile exhaust, household gas, etc.), other (such as radiation, graphite, high-temperature environment Work) can reduce fertility.
2. Some substances that affect hormone secretion, such as estrogen-like hormones, feed for rapid fattening of animals, various plastic utensils, chemical diluents, PCBs, bisphenol A, alkyl phenols, phthalates or androgen antagonists, are sources of endocrine disruptors, totaling more than 70 kinds. These chemicals produce estrogen-like components in the environment, and when they enter the male organism, they can seriously interfere with the endocrine system and can lead to malformations of the reproductive tract, reduce the number of sperm and affect sperm production.
3, lifestyle habits also have an impact on fertility, has been clear, including smoking, alcohol, drugs, wearing tight pants, sauna, etc.; long-term consumption of crude cottonseed oil can lead to infertility; for sedentary men lack of exercise, sperm production will also be affected;
4, and long-term in more electromagnetic wave environment, such as radar, mobile base stations, long-term improper use of computers, microwave ovens, television, washing machines, chargers, etc.,
5, some drugs affect male fertility: common tumor chemotherapy drugs,. The actual fact is that you can find alternative drugs that do not affect the sperm function, and if you must use them, you can consider freezing and preserving semen before treatment.
Third, the semen examination of the missionary points.
1. Requirement of abstinence time: Abstinence should be at least 48 hours but not more than 7 days before semen specimen collection. Abstinence for 3-5 days is preferable. If seminal plasma biochemical examination is required, it is recommended to abstain from sex for 4-7 days. At the same time, it should be noted that seminal emission is generally regarded as incomplete seminal discharge and cannot be used as a basis for calculating the number of days of abstinence.
2, semen specimen collection method masturbation method: is the recommended method of sperm extraction. Wash your hands and penis before masturbation, and ejaculate all the semen into the container by masturbation. The process of taking semen should not be used, lubricant or saliva, and semen specimens should not be contaminated by urine, water, soap, etc.
3. The semen retrieval should be complete and all semen collected into the container, do not lose it and affect the results when it is lost.
4. Do not exert yourself, stay up late, drink heavily, have a fever or take a hot bath before or after semen examination.
Fourth, sex hormone test requirements: fasting, blood sampling at 8-10 a.m., full rest for 15-30 minutes before blood sampling (sit down and do not move).
V. Other infertility knowledge
1, under normal circumstances, the couple’s normal single-month pregnancy rate 20-25%, 75% in six months.
2, try to get pregnant naturally: assisted reproduction has a potential genetic risk, as far as possible, the use of life and habit adjustment, drugs or surgery and other methods of natural pregnancy, after a long time trying to fail, or after examination that there is really no effective treatment, before choosing the next treatment measures, artificial insemination, in vitro fertilization, or microscopic fertilization, and follow the basic process from simple to complex.
3, the couple with treatment: fertility of a strong share can partially compensate for each other’s low fertility.
4.Progressive choice of treatment measures: first choose simple, convenient, non-invasive or non-invasive methods
5, the method of sexual intercourse on the time and frequency of sexual intercourse control. It is also important to review the key basal body temperature chart or home rapid urine determination machine to determine the LH concentration (pregnancy paper) before ovulation. Since sperm can remain on the mucosal surface of the uterus for about 48 h and can be continuously active, it is necessary to make intercourse and ovulation occur at exactly the same time. Usually, intercourse takes place every other day before and after the woman’s ovulation. The woman should lie on her back with her hips elevated for 30 minutes after sexual intercourse. Sexual intercourse is best without lubricant, if you must use, it is recommended to use safer vegetable oil, olive oil or oil gel lubricant.
6. If his sperm quality is in a critical state, then every change in his behavior to improve his health may have some significance for pregnancy. If the patient wants to change his habits or wants to live a healthier life, he should be given ample time for these behaviors to work. Remember, it takes 3 months for a man’s sperm production to show if it has improved.
7, fertility diet regulation supplements just might have some effect on fertility,. Very obese or overly thin men may have abnormal hormone levels which are the very factors that affect sperm production. Antioxidant vitamins, especially vitamins A, C and E may also have some effect on sperm quality.
Patients are advised to get as much vitamin as possible from their diet each day, as the body can effectively take vitamins from the daily food intake as opposed to from supplemental pills. Vitamin A includes not only the carotenoid compounds found in carrots, but also other yellow, orange or red fruits and vegetables such as sweet tomatoes, pumpkins, red peppers, and dried peaches.
Spinach is also a good source of the vitamin. Foods rich in vitamin C include citrus fruits (oranges, grapes, papaya, lemons, limes) and green vegetables (cauliflower, Brussels sprouts). Fortified cereals, multi-grain blends, wheat, cheese, shrimp, almonds, hazelnuts and melon seeds are all found to contain high levels of vitamin E. Patients can of course also take some vitamin supplement pills, but be sure not to exceed the recommended daily dose unless your doctor asks you to do so.
In fact, we do not recommend taking any type or dose of vitamins until you have discussed your condition with your doctor. If you are fine and not taking any prescribed medications, it is usually safe to take some high quality multivitamins containing vitamins A and C, along with the recommended daily dose of magnesium and zinc, which is important for the prostate. You can also take 400 U of vitamin E daily. choose appropriate exercise and reasonable physical activity. There is no damage to your body as long as you exercise within limits. Those male athletes who over-exercise, running more than 100 miles per week or cycling more than 50 miles per week, may cause a decrease in sperm count and vitality.
8, do not wear tight pants, it is recommended to sleep with the external genitals exposed, legs apart, the head should be slightly lower than the feet.
9.Avoid sedentary, hot water sitz bath, sun bath, hot water bath is not good for sperm.
10, prohibit smoking, alcohol abuse.
11, to keep the mood, tension, anxiety, worry and other adverse psychological factors can cause the nerve center dysfunction, is the male neuroendocrine dysfunction, resulting in infertility.
12, physical stress many physical stress can affect the production of sperm cells, such as high fever, serious infections or acute and chronic diseases. Exposure to toxic chemicals or radioactive environments is also an important somatic stressor. After medical treatment or suffering a somatic blow, it often takes 3 to 6 months to return to normal sperm production.
