Are you sure you ejaculate sperm every time?

Men may ejaculate after every sexual intercourse, but are you sure that it contains sperm? Azoospermic people also "ejaculate", but the semen does not contain sperm. When it comes to azoospermia, most people may think that azoospermia means infertility. What are the causes of azoospermia in men? Do you know?

What is Azoospermia?

Azoospermia can be divided into two major categories. The first category is testicular spermatogenesis dysfunction, in which sperm cannot be produced, also known as true azoospermia.

The second type is that the testicular spermatogenesis function is normal, but the vas deferens is blocked and sperm cannot be discharged from the body, which is also called obstructive azoospermia.

Causes of Azoospermia

1. Genetic diseases of spermatogenesis disorders: abnormalities of autosomes or sex chromosomes affect testicular sperm production, such as Klinefelter syndrome.

2. Congenital testicular abnormalities: Abnormal testicular development or abnormal testicular position can cause sperm production disorders.

3. Testicular lesions: such as testicular trauma, inflammation, torsion and testicular vascular lesions.

4. Endocrine diseases, hyperpituitarism or hypopituitarism, pituitary tumors, adrenal hyperfunction or hypofunction, hyperthyroidism or hypothyroidism can all affect sperm production and cause azoospermia.

5. Severe systemic diseases and malnutrition can cause azoospermia.

6. Radiation damage and drugs, especially cytotoxic drugs, can damage testicular spermatogenic cells, which can lead to azoospermia in severe cases.

Obstructive azoospermia

The patient has normal secondary sexual characteristics, sexual desire, and sexual function, normal testicular development, and sperm production, but no sperm is discharged due to obstruction of the vas deferens.

The causes include: ① congenital malformations, such as ectopic epididymis, occlusive epididymis, and absent or agenetic vas deferens; ② infection, gonococcal, tuberculosis and some other bacterial infections can cause obstruction of the epididymis and vas deferens; ③ cysts in the epididymis compress the epididymis duct and cause obstruction; ④ injury causes obstruction of the vas deferens.
