Factors leading to male infertility and preparation for eugenics
Factors leading to male infertility
>
Currently, the number of infertile men is increasing, and many are puzzled as to what factors cause their infertility. Experts believe that improper diet and unhealthy lifestyle habits are the main causes of male infertility. In daily life, men should do the following five things to prevent infertility:
>
**1. Avoid inhaling kitchen fumes.**
>
A recent study by the Medical School of China Railway University has discovered that 74 chemicals in kitchen fumes can cause cell mutations, leading to infertility, becoming new evidence of a "household killer." They found that fruit flies fed with condensed oil from kitchen exhaust fans had a 0.54% mutation rate in their chromosomes, and 2.8% of the fruit flies were infertile, indicating significant damage to their reproductive system.
>
**2. Do not bathe in excessively hot water.**
>
Sperm require a constant temperature of 34-35℃ to develop properly. Excessively hot water during bathing can be detrimental. For example, sauna temperatures can reach 70-80℃, more than double the normal bathroom temperature, which is very unfavorable for sperm growth and can lead to excessive dead sperm, causing infertility. Medical experts have learned from the causes of male infertility that some men have testicular temperatures 2-3℃ higher than normal, preventing sperm from surviving. Therefore, young men should be cautious about sauna baths, and the ideal bath water temperature is around 34℃.
>
3. Avoid wearing skinny jeans.
>
Andrology and urology experts believe that tight jeans not only compress male reproductive organs and affect normal testicular development, but also hinder sperm survival due to their lack of ventilation and heat dissipation. Normally, testicular temperature is 3-4°C lower than body temperature.
>
4. Avoid prolonged mountain biking.
>
Mountain bikes have handlebars that are lower than the seat, causing the center of gravity to lean forward and increasing the curvature of the lower back. This puts the testicles and prostate gland in close contact with the saddle, leading to ischemia, edema, and inflammation due to prolonged pressure. This can affect sperm production and the normal secretion of prostatic fluid and semen, potentially causing infertility. Therefore, young men should not ride mountain bikes for more than one hour per day, and a foam cover should be used on the saddle to protect the perineum.
>
**5. Pay attention to your diet to avoid zinc and selenium deficiencies.**
>
Zinc, a trace element, can promote sperm motility, prevent premature sperm disintegration, and facilitate fertilization, demonstrating its significant impact on fertility. Selenium is also an essential trace element for the human body, almost entirely obtained from food. Japanese medical researchers observed 1000 cases of male infertility and found that 37 men had insufficient selenium levels in their semen. Therefore, young men should avoid unbalanced diets and pay attention to consuming foods rich in zinc and selenium, such as fish, oysters, liver, soybeans, and brown rice.

**What should men do for optimal reproductive health?**
>
In recent years, some men have experienced problems with their semen analysis, with issues in both sperm quality and quantity, resulting in many substandard sperm and unqualified individuals. Conception under such circumstances often leads to miscarriage, which is detrimental to fetal development and can complicate the process of healthy offspring. What can husbands do to ensure healthy offspring?
>
**1. Develop good living habits**
>
Unhealthy lifestyle habits have a significant impact on male fertility. Maintaining a good physiological state before conception is crucial. Excessive late nights can lower the body's immunity, so proper rest is essential. Foods harmful to fertility, such as celery, black fungus, and cottonseed oil, can reduce sperm motility and count, and should be avoided. Hot water and high temperatures are detrimental to sperm production, so hot baths and saunas should be avoided. Excessive smoking by men not only affects sperm quality but also, through passive smoking in their wives, can impact the normal development of the embryo and fetus, leading to serious illnesses. Men should quit smoking before conception and for a considerable period after their wives become pregnant.
>
2. Maintain a good mental state.
>
The impact of emotional and psychological factors on eugenics is receiving increasing attention from the medical community. Recent medical research has demonstrated that adverse family environments, stressful work situations, and fearful living conditions are all detrimental to fertility. Data suggests that children conceived under negative emotional and psychological conditions are more prone to temperamental abnormalities, such as social withdrawal or deviant personality traits.
>
Maintaining a positive mood and a relaxed work environment is not only beneficial to men's health but also has a positive impact on fertility. During the process of conception, a harmonious family environment, loving couples, and cheerful emotions are great joys in life and also great benefits for healthy offspring.
>
> 3. Treat existing major diseases.
>
Many diseases can negatively impact reproductive health. For example, if a man has hepatitis B, positive antisperm antibodies, or is infected with sexually transmitted diseases such as Ureaplasma urealyticum, Chlamydia trachomatis, or Mycoplasma hominis, it can all affect his ability to have healthy offspring.
>
4. Stay away from harmful work environments.
>
Exposure to adverse environmental conditions can often affect the sensitive function of the testes, damaging sperm. Studies have confirmed that substances harmful to sperm include lead, mercury, cadmium, tin, arsenic, nickel, cobalt, and benzene, all of which have a detrimental effect on male fertility. Pesticides sprayed in farmland can also cause sperm abnormalities, leading to miscarriage, stillbirth, and birth defects. Pesticides such as benomyl, dichloropropane, methylmercury, and heptachlor epoxide all possess such harmful properties. Data shows that wives of husbands who have been exposed to pesticides are more prone to complications and birth defects. Radiation, isotopes, and electromagnetic waves can all cause sperm abnormalities in men, resulting in varying degrees of birth defects in newborns.

> 5. Commonly Used Medications to Avoid Taking
>
All medicines have side effects, so caution is advised when using them. This is especially important before planning to conceive, and medication use should be approached with extreme caution, avoiding misuse. Clinical research data shows that many drugs can adversely affect male reproductive function and sperm quality, commonly including antihistamines, anticancer drugs, caffeine, morphine, steroids, and diuretics. These drugs can easily lead to birth defects, such as developmental delays, behavioral abnormalities, and brain tumors in infants. Some people believe that taking large doses of traditional Chinese medicine before conception is beneficial for fertility, but this view is also incorrect; improper use of tonics can also cause problems.
>
Men should not abuse medications before trying to conceive. If medication is absolutely necessary, a doctor should be consulted. Even with tonics, a doctor should be consulted to ensure there are no side effects before taking them.
