What are the causes of male infertility?
Men's infertility culprit 1: Haze and other environmental factors
"Haze is one of the reasons for the rapid increase in husband and wife." Experts analyzed that on the one hand, haze contain heavy metals such as lead and manganese, which will affect the quality of male sperm.The function of the device directly affects the secretion of male testosterone hormones, which will affect fertility.
Men's testicular and biological essence functions are more sensitive to certain heavy metals. The toxic substances in the haze have a killing effect on male sophisticated cells.Sperm cells are primitive cells, have the ability to protect themselves, and feel that there are more toxic ingredients in the blood. They are in a dormant state. Excessive replication must be metabolized with a lot of material in blood, so when it dormitory, it cannot play a reproductive role.
It can also be seen clinically that patients with infertility in surrounding are increasing.The higher ratio of domestic IVF can also show that male reproductive function is declining.There is a set of standard values of sperm volume when detecting male reproductive ability. The original sperm volume reached 100 million sperm is normal. It dropped to 60 million 40 million 4 years ago and then dropped to 20 million two years ago.The reduction of the comparison value is still relatively fast, which also shows that the next generation in recent years is indeed more difficult than the original.
In addition, many men may be related to air pollution, water pollution, and radiation pollution in addition to some unknown reasons that may have a certain relationship with smog, especially radiation pollution such as mobile phones and WIFI.
Men's Infertility Culminated 2: Reproductive urinary infection
Infection leads to a certain proportion of male infertility in infertility patients.Men's reproductive tract infection can often cause orchitis, epididymitis, seminal vesiculitis, urethritis, etc.The pathogens that have caused reproductive tract infections include gonococcus, tuberculosis, virus, mycoplasma, chlamydia, trichomoniasis, etc. Among them, germ tract infections caused by mycoplasma and chlamydia are the most common.
All reproductive tract infections can affect the generation of sperm, sperm vitality, and sperm transportation, which has a great impact on men's fertility ability.Stop treatment without authorization, the consequences are unimaginable.
Male infertility Culminated 3: Congenital genital malformations
Ill tests are the most common congenital organ abnormalities, that is, there is no testicles in congenital scrotum. It includes incomplete testicular decreased and testicular ectopic.The testicles stay in the abdominal cavity, under relatively high temperature, the testicular growth is blocked, gradually shrinking, not sperm, lack of fertility.It should be noted that the testicles stay in the abdominal cavity, and the chance of malignant tumors will increase significantly.Therefore, it should be highly valued and corrected early.Generally speaking, you should go to the hospital for surgery after 1 year old.
Diagnosis and treatment of infertility:
1. History.It is important to correctly collect the medical history. Truthful reflection of the following situations: ① Occupation and work: whether there is contact with poison (lead, mercury, phosphorus), radiation, whether high temperature operations, contact time, and whether there are protection measures; nutritional conditions;Smoke, alcohol) and so on.② Started medical history: Have you suffered from gonorrhea, mumps, tuberculosis, epididymitis, prostatitis, pyelonephritis, cystitis or spinal cord injury, have difficulty urination, no diabetes or thyroid dysfunction, etc. The treatment conditions and effects.③ Marriage and sexual living conditions: including attitudes to sexual life, sexual intercourse and frequency; there are nocturnal emission, premature ejaculation, etc., whether there are masturbation habits before marriage; how is the relationship between husband and wife, your wife's health, whether sexual life is coordinated, etc.;The time, the time of cohabitation and whether to take contraceptive measures.④ Staying and treatment: The results, collection time and methods of men's semen; what is the treatment, what is the effect; the woman's inspection.⑤ Family History: Family in the family, patients with infertility, gender malformations, genetic diseases, tuberculosis and other patients.
2. Auclear analysis of chromosome.For external reproductive organs, testicular dysplasia, and unknown sperm -free.
3. Men's infertility physical examination.Including the whole body and reproductive organs.Specifications are the same as internal medicine. In particular, we must pay special attention to development, nutrition and mental conditions, but the focus is on the examination of reproductive organs.The inspection content includes: ① Penis: Pay attention to whether there are serious phimosis, hardline, inflammation, tumor or abnormal development.② urethra: There are no fistula, lower fissure, hardships, or narrow.③ Prostate: The size of the anal diagnosis can be checked, whether there is hard constraints, pension, and massage the prostate solution for examination.④ Testicles: Measure its size, palpation hardness, whether there are hard constraints, tenderness, and pension, whether it is cryptor test.⑤ Sacrifice: Touch the hardness of the vollarization tube, whether there is nodules, tenderness, or not.
4. Laboratory inspection.Except for the semen examination as a compulsory item, the rest should be selected depending on the specific situation of the patient: ① Semen analysis: This helps to understand male fertility, which is a must -check item for infertility.The inspection content includes color, quantity, liquefaction time, pH, sperm count, activity, survival rate and form, etc.② Exposure of in vitro heterogeneous insemination: Even if conventional semen analysis is completely normal, sometimes it is still not possible to represent the insemination ability of sperm.In vitro heterogeneous insemination experiments can more accurately estimate the essence of sperm, which is very valuable to judge men's fertility.Commonly useful is the heterogeneous insemination experiment of human sperm penetrating hamster eggs, with sperm of normal fertility as a control.③ The prostate liquid examination: Normal is milky white, alkaline, and the tiny, folding lecithin particles full of vision under high -power mirrors, a little epithelial cells, starch samples and sperm, the number of white blood cells "10.When there is inflammation, the number of white blood cells increases, and even if it is seen in pile of pus, the lecithin particles are significantly reduced.
5. Immunology examination.Detecting sperm coagulation antibodies or braking antibodies in serum or slurry in the sperm condensing test or braking test.Although there are many types of detection methods, it should be selected according to local conditions.
6. Doppler ultrasound examination.Help to confirm the varicocele.
7. X -ray check.In order to determine the obstructive area of the vascular pipeline, vasters, epididymal angiography, seminal vessels, or urethral angiography can be used.Hyperproopin hemidiers take the butterfly saddle X -ray fault (positive, side positions) to determine whether the pituitary adenoma.
