In 1978, the World Health Organization Special Planning Department of human reproductive research, development and research training, organized a research topic of infertility diagnosis and treatment. 33 medical centers in the world participated in this research. The 7273 information about the infertile couples, including the statistical analysis of the medical history, physical examination, and laboratory test of the man. Related factors.
1. Teste disease
People with poor testicular decrease (that is, the testicles do not normally fall to the scrotum) medical history, the incidence of sperm -free disease has increased significantly, and the incidence of sperm -non -sperm -non -sperm -to -no -sperm -decreased sperm -oriented incidence is 2 times higher than the unilateral.Even if such patients have sperm, the quality of semen is abnormal, especially for the significant increase in young sperm rates.
Testicles damage, here only records those infertility patients with testes or reproductive urinary tract injuries.The incidence of sperm non -semen or semen abnormalities of these patients has increased significantly.
There are very few people with testicular reversing medical history, but often concurrent sperm -free and less sperm.
Patients with orchiditis and epididymitis caused by non -mummitis have a significant decrease in sperm density and activity rate.The testicular volume of such patients is small, and the incidence of adenitis is also higher.
Second, urogenital disease disease
In the entire crowd, the incidence of non -sperm -non -sperm -non -sperm -oriented diseases that have sexually transmitted diseases are similar, but the incidence of abnormal semen analysis is significantly higher than the latter.Sexual communication disease does not seem to affect sperm density, indicating that it will not cause stenosis or blockage of the vasal pipeline.Patients with sexually transmitted diseases are generally manifested in the decline in sperm activity, which is related to the disorders of adrenal gonades, especially related to epididymitis.
Inflammation of the urogenital system is often accompanied by urethral symptoms, and urethral symptoms include dysuria, frequent urination, urgency, hematuria, and difficulty in urination.The quality of these patients is often abnormal, especially sperm form and activity rate.Among patients with symptoms of urinary systems, 27%of people have abnormal prostate liquefaction results, or semen bacterial, or abnormal biochemistry examination, indicating that some of them have adenitis.
3. Other system diseases
The incidence of sperm non -semi -non -sperm disease occurs around adolescence, and may be accompanied by a high possibility of abnormal semen.After adolescence, sperm density is significantly lower than those who are not onset or before adolescence.Only 4.4%of patients with mumps are merged with orchitis, mostly after adolescence.Dispitis, especially bilateral orchiditis, significantly affects the quality of semen and can cause sperm -free.Whether it is unilateral or bilateral orchitis, semen abnormalities increase.In short, when mumps are combined with orchitis, they will have adverse effects on fertility.
