How is male infertility caused?

The causes of male infertility are mainly divided into congenital factors and acquired factors. Innate factors are relatively many, and acquired factors are relatively easier to treat. But overall, it can

Found a solution!

1. Innate factors mainly include:

1. Genetic factors:

According to relevant literature reports, genetic reasons are one of the key factors affecting male infertility, mainly covering: male chromosomal abnormalities and microdeletions in the long arm azoospermia factor (AZF) region of the Y chromosome.

Although male infertility caused by various genetic factors has different clinical manifestations, its common feature is that it affects sperm development, resulting in sparse sperm count, azoospermia or sperm

abnormal.

1. Congenital abnormal development of the reproductive organs.

Common conditions include penis defect, small penis, large penis, severe hypospadias, etc., which makes it difficult for the penis to be inserted into the vagina and semen cannot enter the vagina normally, leading to infertility.

In addition, abnormal testicular development can cause sperm production disorders, resulting in infertility.

2. Acquired factors mainly cover:

1. genital infection.

After the male reproductive organs are infected with pathogenic bacteria, the existence of inflammation will affect the normal secretion of the gonads, reduce the spermatogenic function, change the shape of the sperm, and decrease the vitality and survival period, resulting in fertilization energy

Loss of force, which leads to infertility.

The vast majority of infertile patients have symptoms such as acute orchitis, epididymitis, prostatitis, and urethritis.

1. varicocele.

This is the most common factor in male infertility and is more common in young men aged 20 - 30.

The cause of infertility is not yet fully understood. There are several possible factors, such as blood stasis in the spermatic vein, which causes the local temperature of the testis to increase, leading to degeneration of the seminiferous tube, which has a significant impact on the occurrence of sperm.

has an impact. Metabolites secreted by the adrenal glands and kidneys caused by spermatic vein reflux may affect sperm quality.

1. Bad living habits:

With the changes in human lifestyle, diet structure and behavioral habits, the impact of bad living habits on male fertility has become increasingly significant.

Numerous studies have shown that poor living habits (such as smoking, drinking, staying up late, obesity, and taking saunas) can reduce men's sperm density, directional movement ability and increase the rate of sperm malformation.

1. Occupational or environmental factors:

The testicle is located in the scrotum and its temperature is lower than body temperature. Human sperm can only grow normally at 35.5℃ - 36.5℃. If the scrotum is exposed to an environment 1℃ - 2℃ higher than the body temperature for a long time, it will cause

Changes in the testicular microenvironment, oxygen metabolism and enzyme activity lead to spermatogenesis failure.

If you are engaged in occupations that will increase the scrotal temperature, such as drivers, chefs, welders, etc., it will have an impact on the quality of semen.

In addition, long-term exposure to radiation pollution, heavy metal pollution, large doses of electromagnetic radiation, ultrasound, infrared, laser and other working environments may have adverse effects on sperm.

For example, heavy metals easily accumulate in the testicles, which can have toxic effects on the male reproductive system, affect the production and transport of sperm, and then affect the fertilization rate and reproduction rate.

Just like some men who have worked in chemical plants for a long time, their fertility may be greatly affected due to frequent exposure to heavy metals. For another example, a long-distance truck driver, due to sitting for a long time, his scrotum dissipates heat

is poor, and semen quality is also prone to decline.
