Under normal circumstances, the couple gets about 80%to 85%of her pregnancy in the first year, and about 10%to 15%of the couple in the second year will be pregnant.Most infertility patients came to the doctor because of the infertility of many years of marriage. There were no other discomfort. It was only discovered that abnormalities were discovered during the medical examination and laboratory inspection of relevant parties.
Men's infertility, according to the standard of the World Health Organization, is 1 year, referring to the history of infertility life at least 12 months without conceiving the woman.Primary men's infertility means a man never conceive a woman.Secondary men's infertility refers to a man conceived a woman.Generally speaking, men's non -breeding is more likely to recover from primary infertility.
At present, infertility has become a common condition.The normal value of sperm has been reduced from 60 million per milliliter to 20 million per millilate.
The cause of men's infertility disease is very complicated, and the World Health Organization is divided into 16 categories.There are mainly the following aspects:
After the reproductive organs infected with the pathogenic bacteria of male reproductive organs, the existence of inflammation will affect the normal secretion of the gland and the decline in raw sperm function, and reduce the shape of the sperm, vitality and survival period, which will lose fertilization and lead to infertility.Most patients have symptoms such as acute orchiditis, epididymitis, urethritis, and reproductive organs.In severe cases, it can cause vasters, narrow epididymia, and even obstruction, so that sperm cannot be passed smoothly, entering women's body with eggs.
Exmedos of varicocele refers to the expansion of the vine intravenous veins of the sperm. It will be blocked by the blood flow of the testicles, the temperature rises, the metabolic disorders, and the harmful substances cannot be discharged in time, causing the testicular disorder, causing less sperm and sperm deformityThe decrease in vitality causes infertility.
Immune function is abnormal that men produce anti -sperm autoimmune.Human semen contains a variety of antigens. If there are urethritis, prostatitis, epididymitis, orchitis, the blood test barrier will be destroyed, and an immune response will occur, resulting in anti -sperm antibodies.Anti -sperm antibodies can cause sperm to lose, resulting in less essence and sperm -free, and prevent the combination of sperm eggs.
One of the important factors that lead to male infertility are infectious diseases
Infectious diseases are one of the important factors that lead to male infertility.Men's reproductive organs include external genitals, adrenal glands, epididymia, and testicles. The above parts are infected by bacteria, chlamydia, mycoplasma, and viruses, and inflammation can occur.
Prostatitis, especially chronic prostatitis, is a common disease of adult men. At a certain stage of the disease, the disease will occur, premature ejaculation and neurasthenia, which will undoubtedly affect fertility.Spermitis is easily converted into chronic after the onset of onset. It often exists or occurs at the same time as chronic prostatitis and chronic epididymitis, and it is often the cause of recurrent epididymitis.Whether it is bacterial or virus seminal vesiculitis and prostatitis, it can inhibit the spermatogenic function.Especially the semen contains bacteria, even if there is no symptoms, it can cause the phenomenon of fine cell decomposition, essential cell poisoning, shorten sperm life, and sperm condensation.The above reasons can cause infertility.
Dispotitis is often complicated by epididymitis. In severe cases, it can develop into epididymia orchitis, and it can also be posted on a systemic disease such as epidemic mumps, syphilis, and tuberculosis.Regardless of the inflammation of the testis or inflammation from other systems, the testicles are damaged.The orchitis caused by epidemic mumps is mostly unilateral onset. If it is bilateral, it can cause infertility due to testicular atrophy. At this time, the serious damage to the essence of epithelium can be seen.Therefore, there is still a reproductive ability after unilateral testicular damage. If bilateral damage is damaged, it can cause young sperm or sperm -free.Testitis or epididymitis infected by gonorrhea infection can cause testicular dysfunction and obstruction or complete obstruction of epididymal part.
Epididymitis, especially chronic epididymitis, often exists at the same time as chronic prostatitis and chronic seminal vesiculitis.During the development of inflammation, the epididymal lumen can be narrowed due to scar formation, and even develops into a completely occlusion of the lumen. If the lesion becomes bilateral, it can cause infertility.
