What are the causes of male infertility?

Marriage is a big event in life, it means that one person's life will merge with another person's life. Having a child is also a big event, it means that a third person will enter the lives of two people, and the growth of this little life still depends on our care. But many people are worried about not having children. Today, I will tell you some common causes of male infertility.

Semen abnormalities:

(1) Azoospermia or oligospermia When the sperm density in the semen is less than 0.2×10[9]/ml, the woman's chance of pregnancy is reduced, resulting in infertility. This type of infertility can be divided into permanent and temporary. The former is seen in patients with congenital testicular development disorders or severe testicular and seminal vesicle lesions; the latter is more common in patients with excessive sexual intercourse that leads to a temporary failure of spermatogenesis, which is generally characterized by a decrease in sperm rather than a total absence of sperm.

(2) Poor sperm quality: Too many inactive or dead sperm in semen (more than 20%), or sperm with very poor motility or more than 30% abnormal sperm, can often cause infertility.

Spermatogenesis disorders:

(1) Testicular disease

Testicular tumors, testicular tuberculosis, testicular syphilis, non-specific testicular inflammation, testicular atrophy after trauma or spermatic cord torsion, testicular absence, etc. can all cause spermatogenesis disorders and infertility.

(2) Chromosomal abnormalities

Sex chromosome abnormalities can cause poor differentiation of sex organs such as testicles, resulting in true hermaphroditism and congenital testicular dysgenesis. Autosomal abnormalities can lead to metabolic disorders of gonads and spermatogenic cells.

(3) Sperm dysfunction

Long-term consumption of cottonseed oil can affect sperm autoimmunity and cause sperm dysfunction.

Systemic factors:

(1) Mental and environmental factors: Sudden changes in living environment leading to long-term mental stress, high-altitude, high-temperature, ultra-intensive labor, and radiation work.

(2) Nutritional factors: severe malnutrition, vitamin A and vitamin E deficiency, and deficiency of trace elements such as zinc and manganese.

But infertility is not unchangeable. Modern medicine has many treatments that can help families welcome new life. Even if it really cannot be changed, there is no need to force it. Because this is something that should be left to nature. Too much intervention will not benefit either party. If it is caused by systemic factors, men can treat it by strengthening their physical exercise.
