Male infertility is the most difficult for men to express! Having a child and enjoying it is the fervent hope of every family.
This shows how painful it is to suffer from infertility. Today I will talk to you about the most common male infertility - azoospermia.
Sperm are germ cells produced by the male testicles and are messengers of life. The task of sperm is to combine with the egg to form a fertilized egg, which is then transported by the fallopian tubes to implantation in the womb for development.
But many men have no sperm on the test, what's going on? In general, azoospermia is diagnosed if sperm is not found on semen examinations more than two times.
There are two main conditions of general azoospermia: one is non-obstructive azoospermia: that is, the testicles really do not produce sperm.
The other is obstructive azoospermia: the testicles are constantly producing sperm, but due to diseases such as the testicles, epididymis, and vas deferens, sperm cannot be output.
Next, let's talk to you in detail, where did the sperm go?
Disorders of testicular factor generation
Congenital testicles, testicular instability or testicular dysplasia, the most common of which is cryptorchidism, the testicles should enter the scrotum when the normal fetus develops to 8 months, if not into the scrotum is called cryptorchidism.
Azoospermia may occur if bilateral cryptorchidism, particularly high cryptorchidism, or if there is also a lesion in one side of the cryptorchidism and the testicle on the other.
Testicle infection
Bilateral orchitis, including viral mumps complicated by bilateral orchitis, especially prepubertal infections leading to the development of azoospermia.
Blood circulation disorders in the testicles
Such as scrotal, inguinal surgery, trauma, inflammation, etc., causing testicular blood supply disorders, resulting in low testicular spermatogenesis function.
Radiation long-term irradiation, the destruction of the fine semiferens, so that the testicles atrophy, according to statistics, a irradiation of 100 ~ 600 pull, 7 weeks after the emergence of azoospermia, stop irradiation, 5 months after the sperm began to recover.
Drugs and chemicals
Long-term application or excessive use of certain drugs will affect the spermatogenic effect of the testicles. Chronic alcoholism, as well as long-term exposure to chemicals such as arsenic, aluminum, benzene, and amine, can affect the spermatogenesis of the testicles.
varicocele
This disease can cause local increases in the temperature of the testicles, impaired venous return of the testicles, reduce the oxygen supply of the testicles, and hinder the excretion of toxic substances, inhibit the endocrine function of the testicles, interfere with the normal metabolism of the testicles, and eventually lead to testicular spermatogenesis disorders.
Vas deferens blockage
Normal spermatogenesis of the testicles is a prerequisite; but this condition alone is not enough, and the vas deferens must be unobstructed.
Chromosomal abnormalities
Genetic factors cause abnormal embryogenesis, chromosomal variation, deletion, translocation, and abnormal testicular development in adulthood leading to the emergence of "azoospermia", such as the common Kerner syndrome, which is clinically characterized by small testicles and azoospermia.
Azoospermia accounts for a huge proportion of male infertility. But as long as the treatment is appropriate, it is also possible to make the spouse pregnant through treatment.
