A. Is there an optimal age for men to have children?
Many people think that the best age for fertility is for women, but there is no limit for men?
In fact, the best age for men is before the age of 35. After the age of 35, the quality of sperm begins to decline, and although men are still fertile beyond the age of 45, the quality of sperm is significantly lower, which can easily affect the development of the fetus. Therefore, from the point of view of eugenics, it is best that the age of male fertility does not exceed the red line of 45 years old!
Second, the male sperm quality why a year is not as good as a year?
(a) The current situation is worrying.
1, a domestic group of 19 to 28 years old healthy college students semen quality survey found that sperm abnormalities accounted for 37.2%. The passing rate of voluntary sperm donors in Shanghai was no more than 21%.
2. In the past 20 years, the quality of Chinese male semen has been declining at a rate of 1% per year, and the number of sperm decreased by 40%.
3. Worldwide, about 10% to 20% of couples are unable to have children, with female factors accounting for about 35%, male for about 35%, and problems with both accounting for about 20-25%.
As re-born men, sperm quality is even less optimistic.
Experts estimate that about 15 percent of couples suffer from infertility.
Look at how many stars in the sky? (Air pollution) Look at how many tadpoles on the ground? (Water pollution)
Just look at the survival of animals to see how dire the decline in human fertility is!
Theo Colburn, “Our Stolen Future” (environmental estrogen causes fewer and fewer sperm), finally let out a heartfelt cry!
(B) Their own vulnerability: male sex chromosome XY, female sex chromosome XX, small sperm, large eggs. The biological characteristics of sperm determine that sperm are more vulnerable than eggs. During the formation of sperm deformation, DNA damage and repair system functions are subsequently lost, while somatic cells and egg cells are able to repair more than 90% of the primary genetic material damage. Foreign studies have shown that at least 5% to 10% of male infertility is caused by genetic defects.
(iii) Other causes.
1. Environmental hormones block spermatogenic signaling pathways or directly destroy spermatogenic cells: 70 to 100 kinds of environmental hormone chemicals have been identified, many of which are in close contact with human daily life, such as residues of plastic products, foam disposable products, pesticides, feed and food additives, detergents, cosmetics, hormones, pesticides, herbicides, etc. (The body is also fighting information war!)
2, “electronic fog” (a variety of electronic devices (including cell phones) generated by electromagnetic waves): cause human physiological disorders, resulting in serious abnormalities in the testes spermatogenic cells. Interference with sperm-egg combination.
3, unhealthy lifestyle. In daily life, some bad habits and insignificant daily behavior are very easy to trigger male fertility decline.
(1) long-term smoking, alcohol abuse, drinking cola, coffee, eating fried food, cottonseed oil (cotton phenol), etc.
(2) Sedentary, sauna, continuous driving (more than 2 hours), all-night Internet surfing, love to wear tight pants, laptop computers operated on the legs, etc. Because the temperature at which sperm can develop normally is about 34 degrees Celsius.
4, work environment: painters, shoe factory workers, decorators, highway toll collectors, etc. long-term exposure to chemical environmental pollution (benzene, formaldehyde, cadmium); welders, radiologists.
5, drugs, drugs impact: affect sexual function and sperm quality.
(1) stomach drugs, anti-hypertensive drugs.
(2) psychotropic drugs (clozapine).
(3) Immunosuppressants: Raglan polysaccharide tablets.
(4) Antibiotics, antivirals, antitumor drugs.
(5) Hormonal drugs.
(6)Drugs.
(6) Radiotherapy.
(7) Increased stress in life, long-term stress, endocrine disorders, more common in middle-aged men. Some couples are afraid of being chased all day long when to have children, and over time suffer from “social phobia”.
8, reproductive system diseases
(1) Infection.
(2) Varicocele.
(3) Testicular syringomyelia.
(4) Other.
9, other system diseases affecting reproduction (not to be ignored!)
(1) Digestive system diseases: gastric ulcer (low 25%), cirrhosis of the liver.
(2) blood system: the nutrients that produce blood also produce sperm (vitamin B12). Sperm and blood are homologous.
(3) Kidney diseases: renal failure, hemodialysis (sexual function, reproduction).
(4) Endocrine diseases: hyperthyroidism (hyperthermia?) , diabetes (sexual function, reproduction).
Third, what are the common types of male infertility?
Male fertility decline is mainly manifested as azoospermia, oligospermia, weak spermatozoa and deformed spermatozoa. This causes infertility, or reduced chances of fertility, on the one hand, and on the other hand, even if the woman is pregnant, it may lead to fetal stunting or cessation of development.
Fourth, after 45 years old, can men still have children?
Some of the first child is the success of the pill, the second child should definitely be careful.
Many men think that the first child is very smooth, the second child should be no problem, not necessarily.
The right attitude is that, no matter what, it is better to have a thorough examination before preparing for the second child to avoid regrets.
The reason is that for middle-aged men, the many unfavorable factors mentioned above have a cumulative consequence. In middle-aged men, life and work are more stressful, there are more underlying diseases and more medications are taken naturally. These have a negative impact on the fertility function.
Five, five ways to help you succeed in childbirth
1, healthy life
(1) Stay away from smoking and alcohol.
(2) Keep your scrotum at the right temperature.
(3) Control your weight.
(4) Reasonable adjustment of diet structure.
(5) Prevent magnetic radiation: keep a distance of not less than 70 cm from the computer screen, and keep a distance of not less than 120 cm from the back and sides of the computer.
(6) Keep away from toxic substances: such as clothes taken back from dry cleaners should be left for a few days before wearing.
(7) Go to bed on time.
(8) Exercise reasonably.
(9) Have a regular sex life.
2.Chinese medicine treatment
3.Food therapy
(1) Calcium: Calcium plays a pivotal role in the movement of sperm, energy acquisition, maintenance of hyaluronidase activity and in the fertilization process. For example, milk, sweet almonds, mushrooms, rib soup, raisins, nori, shrimp, kelp, golden needles, etc.
(2) supplement arginine: arginine is the main ingredient that constitutes the sperm head and improves sperm motility. Sea cucumber, sunflower seeds, tofu skin, frozen tofu, eel, yam, cuttlefish, sesame, peanut kernel, loach and ginkgo, etc.
(3) Fructose supplement: The activity of sperm is related to the amount of fructose contained in the seminal vesicles. Honey, pear, apple, grape, pineapple, sweet orange.
(4) supplement magnesium: magnesium to improve the fertility of men. Soybeans, potatoes, walnuts, oatmeal, seafood.
(5) Zinc supplement: Zinc is a necessary substance for sperm metabolism and enhances the vitality of sperm. Oysters, animal liver, clams, shrimps, shellfish, pecan nuts, buttermilk, beans, lotus seeds.
(6) Kidney tonic foods: black beans, black rice, black sesame, walnuts, black fungus, etc. Animal meat, eggs, bone marrow, black sesame, cherries, mulberries, yams.
4, relax the mind. Do not be nervous when you encounter problems, some conditions are only temporary, such as infection, alcoholism, smoking, overload, hot environment, too tight underwear, insomnia, work and emotional stress, etc.. Marriage should not be linked to children. The presence or absence of children is not a litmus test for marriage, which is purely between the two spouses. Travel to get pregnant.
5. Assisted reproductive technology.
Conclusion: Relax, be cautious, cooperate with treatment and be patient.
