1. Sexually transmitted diseases cause semen abnormalities
In the entire crowd, the incidence of sexually transmitted diseases is similar to the incidence of sperm -non -sperm -non -sperm disease, but the abnormal incidence of semen analysis is significantly higher.Sexually transmitted disease does not seem to affect sperm density, indicating that it will not cause stenosis or blockage of vasters.Sexually transmitted diseases are generally manifested in the decline in sperm activity, which is related to the disorders of adrenal gonades, especially the epididymitis.It should not be ignored that the infection of the chlamydia and the chlamydia of the sandylona is also common in clinical practice, and these infections do not have significant symptoms and have a certain concealment.
2. Mumps
Mumps before and after puberty will not cause an increase in the incidence of sperm non -sperm, but the possibility of high abnormal semen.The density of sperm density after puberty is significantly lower than those who are not on the disease or the onset of adolescence.Only 4.4%of patients with mumps are combined with orchitis.Before adolescence, the patient rarely merges orchitis, but the disease can occur after puberty.Dispositis significantly affects the quality of sperm and increases the incidence of spermatozoa, especially bilateral orchicitis.Whether it is unilateral or bilateral orchitis, the abnormal semen analysis increases.In short, when mumps, especially in orchitis, have a bad impact on fertility.
3. The problem of testicular itself
Poor testicles are also a very common factor. The incidence of sperm -free disease without sperm -free disease has a significant increase in this medical history, and the incidence of sperm -non -spermosis is twice as high as unilateral.Even if such patients have sperm, the quality of semen is abnormal, especially in the significant increase in young sperm.
Teste damage often affects its normal function. Although many men have had a certain degree of testicular injury in their lives, they only record the cases of infertility patients with testicular or reproductive urethral injuries.The incidence of sperm non -sperm or semen of these patients has increased significantly.Teste damage is often accompanied by urethral symptoms (16.8%), while 8.8%of those with non -injury have such symptoms, which are significantly different.In addition, the former adenal infection rate is also high.Although testicular reversal, although the incidence is not high, once the onset is often concurrently concurrently sperm and young.
Etate or orchitis is also a common disease. The sperm density and activity rate of these patients are significantly lower than those without such a medical history. The testicular volume is small.There may be immune factors in urethral symptoms, and the incidence of adenitis is also higher.
4. Urinary system disease
If it is difficult to urinate, frequent urination, hematuria and other symptoms, seminal vesiculitis and possibilities should be excluded.These patients have a high tendency of sperm non -sperm, and more common semen quality is abnormal, especially sperm morphology and activity rate.Among patients with symptoms of urinary systems, 27%of the prostate liquid testing abnormalities, or abnormal semen bacterial, bacterial or biochemical examination should be further examined.
5. Other diseases
Bronchitis may also cause semen abnormalities, and bronchitis is often a clinical manifestation of cilia dysfunction that extends the whole body.Among these patients, the incidence of sperm -free disease has increased significantly.The testicular volume of all such patients is normal, indicating that sperm -free is caused by the blockage of sperm -vastrus pipes.The abnormal rate of semen analysis in patients with bronchitis increases, and the average density density and sperm of sperm and forward exercise are lower.Diabetes is also common. Diabetes is associated with ejaculation dysfunction, which does not cause sperm -free or sperm quality abnormalities. Therefore, the effect of diabetes on fertility is caused by sexual dysfunction.Patients with a history of nervous system are often manifested as ejaculation disorders, but the incidence of abnormal sperm -free and semen quality does not increase.
