Microtesticular azoospermia

For men, sexual function is something they are often proud of. However, there are always some men whose testicles are relatively short, and there is no fertile mirror in the ejaculated semen. This is also called azoospermia in medicine. It not only brings physical infertility, but also is a big blow to men's self-confidence. There are two main reasons for this. One is that the testicles themselves have functional failures, and the other is that there are problems with the male's sperm secretion.

If a semen examination reveals no sperm, we call it azoospermia. As one of the most difficult infertility diseases to treat, azoospermia has brought deep pain to patients and countless troubles to doctors. "The absence of any sperm in the ejaculated semen for three consecutive times is called azoospermia." Azoospermia accounts for about 15%-20% of male infertility patients. There are many causes, which can be generally divided into two categories. One is the dysfunction of the testicles themselves, which is called primary azoospermia or non-obstructive azoospermia. The second is that the testicular spermatogenesis function is normal, but due to blockage of the vas deferens, sperm cannot be discharged from the body, which is called obstructive azoospermia.

reason

1. Endocrine diseases, hyperpituitarism or hypopituitarism, pituitary tumors, adrenal hyperfunction or hypofunction, hyperthyroidism or hypothyroidism, etc.

2. Congenital testicular abnormalities.

3. Pathological changes of the testicle itself. Such as testicular trauma, inflammation, torsion and testicular vascular disease.

4. Hereditary diseases. Such as autosomal or sex chromosome abnormalities, Klinefelter's syndrome, etc.

5. Blockage of the vas deferens.

6. Radiation damage and drugs damage testicular spermatogenic cells and cause azoospermia.

Clinical manifestations

1. No sperm is found in semen routine examinations for more than 3 times.

2. Immunological examination can determine whether it is immune infertility

3. Vasography can determine whether the sperm duct is blocked and where the blockage is.

4. Gross testicular lesions can be detected during testicular B-ultrasound, and testicular biopsy can provide a more reliable basis for diagnosis and treatment.

5. If no sperm is found after the semen is centrifuged and precipitated for three times, it can be diagnosed as azoospermia.

6. During physical examination, the testicular volume is less than 10 ml and the texture is abnormally soft, indicating poor testicular function.

7. Most patients are found to have azoospermia when they come to the hospital for infertility examinations because they have been married for many years and have not been able to make their wives pregnant without taking any contraceptive measures.
