The profound impact of environment and lifestyle on sperm quality

(1) The effect of temperature: The reason why the testes in the scrotum are outside the body cavity is because sperm

Its formation and growth require a relatively low temperature of 35℃; both high and low temperatures will severely affect its growth.

Quality. Studies have shown that cold weather can interfere with sperm production and motility, and low temperature environments...

The number of sperm with abnormal ultrastructure increases significantly under certain conditions. High-temperature work can cause testicular temperature to exceed [a certain value].

The physiological temperature for sperm growth and development not only significantly affects the function of spermatogenic cells, but also...

This can cause abnormalities in testicular metabolism and various biochemical and immune responses, which can disrupt the spermatogenic microcirculation environment.

Changes in sperm production cause sperm to pass through the epididymis faster and mature slower, ultimately leading to changes in sperm motility.

Sperm disorders and sperm maturation disorders can lead to decreased semen quality or a large number of sperm in the testes.

Death, and even testicular atrophy.

(2) Effects of electromagnetic radiation: The testes are the most sensitive tissue in the human body to electromagnetic radiation.

One of the organs, because the seminiferous epithelium within it divides frequently, and ionizing radiation can cause cell damage.

Damage to the membrane has a long-term detrimental effect on the spermatogenesis process. Studies have found that placing a mobile phone in...

Men who carry phones in their trouser pockets or at their waist have higher sperm motility than men who don't carry phones or keep them elsewhere.

Low libido; decreased semen quality among radar operators, primarily characterized by increased sperm abnormality rate. Microwave.

It can also damage spermatogenic cells through thermal effects, affect the endocrine function of the testes, and cause sperm abnormalities.

Increased deformability and decreased quality.

(3) Effects of high-frequency vibration: on semen analysis of personnel engaged in continuous and intense vibration operations.

The results showed that the proportion of this population suffering from azoospermia, oligospermia, asthenospermia, and teratospermia was relatively high.

Studies have shown that sustained, severe vibrations can impair autonomic nervous system function, immune function, and hemodynamics.

Abnormalities in the endocrine function of endothelial cells and other cells can all affect life.

Reproductive function, directly leading to sperm maturation disorders, etc.

What chemical factors affect sperm quality?

Chemical factors mainly originate from environmental pollution, such as pesticides and fertilizers used in agricultural production and industrial and mining activities.

Toxic chemicals in waste residue, wastewater, and domestic waste discharged by enterprises can be released through various channels.

If these contaminated channels enter the living environment, they will pose a threat to the health of organisms and humans in such polluted environments.

Serious harm. In today's society, environmental pollution has become a major factor harming male reproductive function.

Harmful substances damage the male reproductive system through various pathways: ① Direct action on

Reproductive organs, affecting the Sertoli cells of the testes and the spermatogenesis process; ② Disruption of the blood-testis barrier,

It has a direct cytotoxic effect on germ cells; ③ It acts on the gonadal axis, leading to stimulation of the gonads.

This weakens and affects the production of sperm and sex hormones; ④ It indirectly affects the mother during the embryonic period.

Inducing chromosomal mutations in male infants may affect the sperm production process.

Common pollutants include pesticides, herbicides, insecticides, plastics, electronics, and...

Organochlorine compounds and organophosphorus compounds are commonly found in the pharmaceutical industry, dry cleaning spraying, and interior decoration materials.

Compounds, bisphenol A, phthalates, organic solvents, etc. Many studies have shown that contact with benzene...

It may cause infertility, miscarriage, stillbirth, and birth defects. Studies have reported the effects of pesticides on human health.

Germ cells exert cytotoxic effects, leading to a decline in sperm quality. Some studies have investigated 23 organophosphate pesticides...

A survey of pharmaceutical factory workers and 43 workers exposed to non-organophosphorus pesticides found that occupational exposure to...

Organophosphorus pesticides have a moderate negative impact on semen quality. Lead contamination is reproductively toxic and can damage sperm.

Bad sperm can cause male infertility.

What unhealthy lifestyle habits affect sperm quality?

(1) Drivers, white-collar workers, and those who sit for long periods and lack exercise: can cause damage to the testes, epididymis, and spermatic cord.

Pressure affects blood circulation, causing blood to pool in the venous plexus around the spermatic cord and increasing pressure within the veins.

High levels of oxygen affect testicular metabolism, leading to carbon dioxide buildup in the blood and causing hypoxia in the testes and epididymis.

Poor waste metabolism is detrimental to sperm production and storage.

(2) Strenuous exercise can affect sperm production: The energy required for human exercise comes from glucose.

The oxidation and breakdown of glucose ensures a sufficient supply of oxygen through our respiration, and glucose will be released during respiration.

In the presence of sufficient oxygen molecules, it decomposes into carbon dioxide and water, producing energy. However, it is violent.

During exercise, due to the enormous energy expenditure, even with deeper and faster breathing, the body's oxygen demand cannot be met.

In this state of oxygen deficiency, glucose undergoes anaerobic glycolysis, producing a large amount of milk.

Acidic metabolic products such as acids enter the testes through the bloodstream and can affect sperm production.

A large amount of reactive oxygen species is generated in the semen. The reactive oxygen species in the semen exceed the antioxidant capacity of the semen itself.

After the ability is restored, it will have an adverse effect on sperm.

(3) The effect of smoking on semen quality: It is generally believed that cigarettes contain nicotine, ...

Smoking contains various substances such as carbon dioxide, cadmium, and lead. It can affect the biosynthesis of testosterone, and heavy smoking can exacerbate this effect.

It can also cause penile artery constriction, hindering sperm production and maturation, leading to decreased sperm motility.

The rate of normal sperm morphology decreased. This difference became more pronounced with increasing amount and duration of smoking.

Significantly, it can even cause sperm chromosome abnormalities.

(4) Effects of alcohol on semen quality: After drinking a lot of alcohol, ethanol and its metabolite ethanol will increase in semen quality.

Aldehydes can directly or indirectly inhibit the activity of enzymes involved in testosterone synthesis, thereby impairing testicular spermatogenesis.

Alterations in the structure and number of chromosomes in germ cells can manifest as a prolonged semen liquefaction time.

Longer sperm count, reduced sperm survival rate, and decreased sperm motility.

(5) The impact of psychological stress: Modern people generally feel stressed and have different mental and psychological states.

This can often lead to neuroendocrine disorders and interfere with testicular spermatogenesis. Studies have found that...

Sperm motility was significantly lower during final exams than three months after the exams.

The proportion of abnormal sperm also increased, indicating that strong psychological stress has a negative impact on male sperm quality.

The quality of the sample has a certain impact.
